is there private information in the fx market the tokyo experiment it is a common view that private information in the foreign exchange market does not exist we provide evidence against this view the evidence comes from the introduction of trading in tokyo over the lunch hour lunch re turn variance doubles with the introduction of trading which cannot be due to public information since the flow of public information did not change with the trading rules having eliminated public information as the cause we exploit the volatility pattern over the whole day to discriminate between the two alternatives private information and pricing errors three key re sults support the predictions of private information models first the vola tility u shape flattens greater revelation over lunch leaves a smaller share for the morning and afternoon second the u shape tilts upward an impli cation of information whose private value is transitory finally the morning exhibits a clear u shape when tokyo closes over lunch and it disappears when trading is introduced

after hours stock prices and post crash hangovers after hours pricing in foreign equity markets of multiple listed u s securities appeared to be efficient in predicting new york prices in the weeks immediately following the october 1987 crash but relatively uninformative in succeeding months by contrast daily changes in new york prices appear to be efficiently incorporated in after hours trading on both the tokyo and london exchanges throughout the sample period this paper suggests that the asymmetry and temporal variations in cross market correlations are consistent with rational investor behavior in equity markets with nonzero transaction costs and time varying share price volatility in the wake of the october 1987 crash a number of studies have provided evidence of significant international linkages among national equity markets where high frequency movements in the share price indices of national exchanges appear to induce sympathetic price movements in subsequent trading on other national exchanges however the cross market correlations are generally much larger in periods of extreme volatility and appear to subside to modest or even negligible associations during periods of more normal trading activity since the constituent stocks of national exchange indices are not identical it may be that the episodic increases in correlated movements of the indices are due to changes in the actual or perceived relative importance of common factors in periods of unusual volatility the thrust of this paper is to remove the issue of the disparate composition of the price indices of national exchanges by examining the prices of a set of

economic policy uncertainty financial markets and probability of us recessions we use probit recession forecasting models to assess the ability of economic policy uncertainty indexes developed by baker et al 2013 to predict future us recessions the model specifications include policy indexes on their own and in combination with financial variables such as interest rate spreads stock returns and stock market volatility both in sample and out of sample analysis suggests that the policy uncertainty indexes are statistically and economically significant in forecasting recessions at the horizons beyond five quarters the index based on newspaper reports emerges as the best predictor outperforming the term spread at the longer forecast horizons

day of the week effects and asset returns the number of empirical studies using daily stock returns is rapidly increasing researchers generally assume that the distribution of stock returns is identical for all days of the week a convenient statistical assumption but not a necessary condition of market equilibrium nevertheless there are reasons to suspect that the distribution of returns may vary according to the day of the week the most obvious is the impact of weekends on monday s return since monday s return is calculated over three instead of one calender day the mean and variance may well be higher on monday compared with any other daily return perhaps three times as large previous research has examined the daily distribution of stock returns for a monday effect while fama 1965 does not compare daily mean returns he does report that monday s variance is about 20o greater than other daily returns with a traditional distributional assumption regarding the returns on a financial asset specifies that the expected returns are identical for all days of the week contrary to this plausible assumption this paper discovers that the expected returns on common stocks and treasury bills are not constant across days of the week the most notable evidence is for monday s returns where the mean is unusually low or even negative several explanations of the results are investigated but none proves satisfactory aside from documenting significant day of the week effects the implications of the results for tests of market efficiency are examined while market adjusted returns continue to exhibit day of the week effects these effects are no longer concentrated on monday during the last year we have had many conversations with our colleagues throughout the professions we are particularly thankful to the participants at sessions of the western and american finance associations where preliminary versions of this paper were presented special thanks are due to gene fama gailen hite jon ingersoll robert jarrow merton miller clifford smith and rex thompson the expert research assistance of frank rabinovitch and youngsup yun is gratefully acknowledged 1 the list of papers using daily stock returns is too long to name recent examples include charest 1978 dodd 1980 banz 1981 and reinganum 1981

information flow and pricing errors a unified approach to estimation and testing this study examines whether rates of information flow differ between trading and nontrading periods and whether the variances of pricing errors differ at the open and close of trading the approach improves on existing methods by allowing for correlation between pricing errors and information flow and by conducting inferences at the individual security level the daytime rate of information flow is about seven times the overnight rate and the variances of pricing errors at the open are not different from those at the close of trading this evidence differs from existing results based on return variance ratios much of the empirical market microstructure literature predicates its analysis on a model in which price changes have a permanent information related component and a transitory market friction or dealer cost component two questions that have received a great deal of attention relate to the behavior of these components the first is whether and to what extent the rate of information flow into prices differs during trading and nontrading periods this is equivalent to asking whether the variance of the permanent component per unit time is different during periods when trading occurs than when trading does not occur the second question is whether pricing errors of differing magnitudes are associated with different trading mechanisms or trading preceded by an overnight period of nontrading this corresponds to asking whether the variance of the transitory component is different depending on which trading mechanism is used or whether trading has been halted for a time more generally these questions relate to whether the permanent and transitory components of price changes are heteroskedastic although both questions share the context of this model existing studies typically focus

transmission of the financial and sovereign debt crises to the emu stock prices cds spreads and exchange rates abstract this paper tests for the transmission of the 2007 2010 financial and sovereign debt crises to fifteen emu countries we use daily data from 2003 to 2010 on country financial and non financial stock market indexes to analyze the stock market returns for three country groups within emu north south and small the following results hold for both the north and south european countries while the smallest countries seem to be relatively isolated from international events first we find strong evidence of crisis transmission to european non financials from us non financials but not for financials second in order to test how the sovereign debt crisis affects stock market developments we split the crisis in pre and post lehman sub periods results show that financials become significantly more dependent on changes in the difference between the greek and german cds spreads after lehman s collapse compared to the pre lehman sub period however this increase is much smaller for non financials third before the crisis euro appreciations coincide with european stock market decreases whereas this relationship reverses during the crisis finally this reversal seems to be triggered by lehman s collapse

models of stock returns a comparison in this paper a discrete mixture of normal distributions is proposed to explain the observed significant kurtosis fat tails and significant positive skewness in the distribution of daily rates of returns for a sample of common stocks and indexes stationarity tests on the parameter estimates of this discrete mixture of normal distributions model revealed significant differences in the mean estimates that can explain the observed skewness and significant differences in the variance estimates that can explain the observed kurtosis an alternative explanation for the observed fat tails is the symmetric student model the result of a comparison between the models is that the discrete mixture of normal distributions model has substantially more descriptive validity than the student model for many years both financial economists and statisticians have been concerned with the description of stock market returns the form of the distribution of stock returns is a crucial assumption for mean variance portfolio theory theoretical models of capital asset prices and the prices of contingent claims for example understanding the behavior of the variance is essential to option pricing models empirical tests of asset pricing models and the efficient markets hypothesis draw statistical inferences that are also conditional on distributional assumptions the most convenient assumption for financial theory and empirical methods is that the distribution of security rates of return be multivariate normal with parameters that are stationary over time since the normal distribution is stable under addition any arbitrary portfolio of stocks will also be normally distributed with the additional assumption of risk aversion mean variance theory follows furthermore the assumptions of normality and parameter stationarity are required for most of the econometric techniques typically used in empirical research tests of the normality hypothesis on the daily returns of the dow jones industrial stocks by fama 121 revealed more kurtosis fatter tails than that predicted from a sample of independent and identically distributed normal variates fama concluded from this evidence that the distribution of price changes conforms better to the stable paretian distribution with characteristic exponent

information effects and stock market response to signs of firm deterioration a recent issue of the journal of financial economics june september 1978 is devoted to reporting anomalous evidence regarding market efficiency this study may qualify under the same heading here we examine the market response to information about firms whose future is assessed as being extremely problematic

international transmission of information evidence from the euroyen and eurodollar futures markets abstract this paper examines the information transmission between japan and the us by using the tokyo euroyen and chicago eurodollar futures these two interest rate futures markets provide a better understanding of international information transmission than stock markets which have been shown to exhibit nonsynchronous trading and market segmentation the results show that traders in tokyo chicago use information that is revealed overnight in chicago tokyo the bivariate egarch t model provides no evidence of volatility spillovers in either direction suggesting that the opening price rapidly reflects foreign information the overall results support the hypothesis that the domestic market efficiently adjusts to foreign news the results are also broadly consistent with the covered interest arbitrage effects

round the clock market efficiency and home bias evidence from the international japanese government bonds futures markets abstract this paper examines how information is processed between almost identical international futures markets london liffe and tokyo tse jgb futures in these markets variations in open to open changes are virtually the same as those of close to close changes suggesting that information is transmitted efficiently across markets with small opening pricing errors the overall results confirm market efficiency around the clock yet the intraday u shaped patterns in volume volatility of the london jgb futures suggest home bias in international investments indicating a less global view of trading than expected specifically at the liffe open london investors rush to rebalance portfolios instead of doing so at the tse close which is only one hour before the liffe opens

liquidity dynamics and cross autocorrelations this paper examines the relation between information transmission and cross autocorrelations we present a simple model where informed trading is transmitted from large to small stocks with a lag in equilibrium large stock illiquidity induced by informed trading portends stronger cross autocorrelations empirically we find that the lead lag relation increases with lagged large stock illiquidity further the lead from large stock order flows to small stock returns is stronger when large stock spreads are higher in addition this lead lag relation is stronger before macro announcements when information based trading is more likely and weaker afterward when information asymmetries are lower

does economic policy uncertainty matter for commodity market in china evidence from quantile regression this paper investigates the effect of economic policy uncertainty epu on china s agricultural and metal commodity futures returns across quantiles we address this issue using the panel quantile

price reversals bid ask errors or market overreaction abstract we show that bid ask errors in transaction prices are the predominant source of apparent price reversals in the short run for nasdaq firms once we extract measurement errors in prices caused by the bid ask spread we find little evidence of market overreaction on the contrary we find that security returns are positively and not negatively autocorrelated we also show that bid ask errors lead to substantial spurious volatility in transaction returns about half of measured daily return variances can be induced by the bid ask effect

variance ratio statistics and high frequency data testing for changes in intraday volatility patterns variance ratio tests are routinely employed to assess the variation in return volatility over time and across markets however such tests are not statistically robust and can be seriously misleading within a high frequency context we develop improved inference procedures using a fourier flexible form regression framework the practical significance is illustrated through tests for changes in the fx intraday volatility pattern following the removal of trading restrictions in tokyo contrary to earlier evidence we find no discernible changes outside of the tokyo lunch period we ascribe the difference to the fragile finite sample inference of conventional variance ratio procedures and a single outlier

time series copulas for heteroskedastic data we propose parametric copulas that capture serial dependence in stationary heteroskedastic time series we suggest copulas for first order markov series and then extend them to higher orders and multivariate series we derive the copula of a volatility proxy based on which we propose new measures of volatility dependence including co movement and spillover in multivariate series in general these depend upon the marginal distributions of the series using exchange rate returns we show that the resulting copula models can capture their marginal distributions more accurately than univariate and multivariate generalized autoregressive conditional heteroskedasticity models and produce more accurate value at risk forecasts

the time varying correlation between uncertainty output and inflation evidence from a dcc garch model abstract using a new uncertainty index from baker et al 2012 we evaluate the time varying correlation between macroeconomic uncertainty inflation and output estimation results from a multivariate dcc garch model reveal that the sign of the correlation between macroeconomic uncertainty and inflation changed from negative to positive during the late 1990s whereas the correlation between uncertainty and output is consistently negative

patterns in japanese common stock returns day of the week and turn of the year effects stock markets in the united states and foreign countries exhibit a strong weekly seasonal 1 an empirical regularity for which no theoretical explanation has been found one s belief in this phenomenon would be strengthened if it is known to also occur in capital markets separated from those in the united states by distance institutional arrangements and culture this paper extends the results found in 5 and more closely examines the day to day stock market returns for japan while we find a weekly seasonal in japan its nature is significantly different in a statistical sense from the american one for example the lowest mean return in japan occurs on tuesday not monday as in the united states thus while the day of the week effect for american stocks has been casually called the weekend effect it should not be referred to in this way for japanese stocks the next part of the paper examines causes for the unique japanese seasonal we investigate whether the results in japan are associated with those in the united states and in particular consider whether the low tuesday return in japan and the low monday return in the united states are due to time zone differ ences the settlement process and the measurement error problem also are treated we next consider the relationship between foreign exchange returns and stock market returns the seasonal in daily foreign exchange returns does not offset the seasonal in daily stock market returns thus both japanese and american investors confront a day of the week effect in the japanese stock mar ket our data also allow us to investigate the turn ofthe year effect japanese stock returns in january are significantly above the returns during the rest of the year however unlike some reports using u s data see 12 and 13 we find no interaction in japan between the monday effect and the january effect

directional predictability from oil market uncertainty to sovereign credit spreads of oil exporting countries evidence from rolling windows and crossquantilogram analysis abstract given the recent collapse of oil prices this study investigates the directional predictability from the oil market uncertainty to the sovereign credit default swap cds spreads of four oil exporting gcc countries bahrain qatar saudi arabia and united arab emirates and five other oil exporting countries brazil mexico norway russia and venezuela using the modified bootstrap rolling window approach the empirical results reveal a significant directional predictability from oil uncertainty to the cds spreads of most of those oil exporting countries during the subperiods 2010 2011 and 2014 2015 that is during the periods when oil volatility follows a rising trend the most significant directional predictability is found for qatar bahrain saudi arabia and norway particularly during the 2014 2015 oil price collapse subperiod whereas there is no directional predictability found in the case of brazil for mexico the oil market uncertainty predicts cds spreads mostly during 2014 and for venezuela the directional predictability flows are highly impactful and concentrated during 2011 13 to check the robustness of our estimations we use a novel quantile dependence measure called the cross quantilogram that was developed by han et al 2016 the estimation results of this approach confirm our main findings and indicate that the surge in oil volatility predicts the cds spreads in different quantiles overall the findings highlight that the sovereign credit risk of the gcc and the other oil exporting countries is at least partially driven or directionally predicted by the oil volatility shocks this has important implications for investment and policy decisions

anomalies or illusions evidence from stock markets in eighteen countries abstract this paper examines five seasonal patterns in stock markets of eighteen countries the weekend turn of the month end of december monthly and friday the thirteenth effects we find a daily seasonal in nearly all the countries but a weekend effect in only nine countries interestingly the daily seasonal largely disappears in the 1980s the last trading day of the month has large returns and low variance in most countries many countries have large december pre holiday and inter holiday returns the january returns are large in most countries and a significant monthly seasonal exists in ten countries

private information trading volume and stock return variances new evidence is provided on the determinants of stock return variances first when the tokyo stock exchange is open on saturday the weekend variance increases weekly variance is unaffected however despite an increase in weekly volume second the listing of u s stocks in tokyo substantially increases the number of trading hours but tokyo volume is negligible for these u s stocks and their 24 hour variance is unaffected the overall results are consistent with the predictions of private information based rational trading models but inconsistent with both the irrational trading noise and public information hypotheses

correlations in price changes and volatility across international stock markets the short run interdependence of prices and price volatility across three major international stock markets is studied daily opening and closing prices of major stock indexes for the tokyo london and new york stock markets are examined the analysis utilizes the autoregressive conditionally heteroskedastic arch family of statistical models to explore these pricing relationships evidence of price volatility spillovers from new york to tokyo london to tokyo and new york to london is observed but no price volatility spillover effects in other directions are found for the pre october 1987 period article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

reasons for insolvency amongst small firms a review and fresh evidence the growing and diverse literature on insolvency is comprehensively and critically reviewed the limited portfolio that small firms represent in particular as regards their managerial capabilities is suggested as an added reason for the strong inverse correlation of probability of insolvency with firm size the evidence from a hitherto largely untapped source of data the reports of the british official receiver is analysed using contingency tables the most important reason for their failure given by the owners of insolvent firms is weaknesses in operational management particularly in the adequacy of their capital marked inter temporal and interregional differences are evident within the data

how do exchange rates co move a study on the currencies of five inflation targeting countries abstract this paper does three things first it explores the type of asymmetry in exchange rate correlation for five inflation targeting countries we show their currencies co move more closely with the currencies of some influential foreign countries during joint appreciations than joint depreciations against a world currency second it establishes empirically the linkage between interest rate differentials and exchange rate correlation we find evidence that both widening and narrowing interest rate differentials will reduce the correlation third it proposes a new version of the asymmetric dynamic conditional correlation model the model proves to be capable of providing great insight into the two issues investigated

stale information shocks and volatility we propose a new approach to measuring the effect of unobservable private information on volatility using intraday data we estimate the effect of a well identified shock on the volatility of stock returns of european banks as a function of the quality of public information available about the banks we hypothesize that as publicly available information becomes stale volatility effects and its persistence increase as private information of investors becomes more important we find strong support for this idea in the data we further show that stock volatility is higher just before important announcements if information is stale

intraday volatility in international stock index futures markets meteor showers or heat waves the international transmission of intraday price volatility among the united states united kingdom and japanese stock index futures markets in the period 1988 1994 is investigated in this paper the empirical results based on extreme value estimators and vector autoregression indicate the rapid transmission of information between markets the volatilities of the u s and u k futures markets appear to follow a meteor shower rather than a heat wave type of process this means that these volatilities react to shocks from other markets i e they cannot be described only by their past values however the heat wave hypothesis is not rejected for the japanese market meaning that the shocks to japanese volatility are mostly country specific a multivariate garch model supports the u k and japanese but not the u s results

a multivariate garch model of international transmissions of stock returns and volatility the case of the united states and canada this study examines the short run dynamics of returns and volatility for stocks traded on the new york and toronto stock exchanges the main finding is that inferences about the magnitude and persistence of return innovations that originate in either market and that transmit to the other market depend importantly on how the cross market dynamics in volatility are modeled moreover much weaker cross market dynamics in returns and volatility prevail during later subperiods and especially for canadian stocks with shares dually listed in new york implications for international asset pricing hedging strategies and regulatory policy are discussed

economic policy uncertainty shocks and stock bond correlations evidence from the us market abstract this paper examines the effects of economic policy uncertainty shocks on stock bond correlations for the us market we devise a general framework which distinguishes a positive shock from a negative one and nests either as its special case the results show that innovations in the policy uncertainty index impact negatively and asymmetrically on the subsequent stock bond correlations which are characterized by a structural break and positive type asymmetry

the effect of earnings surprises on information asymmetry abstract we examine the effect of earnings surprises on changes in information asymmetry we hypothesize and find that asymmetry is lower higher in the quarter following positive negative earnings surprises compared to firms that meet the consensus analyst earnings forecast the relations between earnings surprises and information asymmetry are stronger when the surprises are more likely to capture investors attention examining the source of these changes we show that decreased information search activities is the most important factor for asymmetry declining after positive surprises for negative surprises decreased uninformed trading plays a dominant role increasing asymmetry

the international transmission of information in eurodollar futures markets a continuously trading market hypothesis abstract this paper studies the transmission of information in three eurodollar futures markets the imm simex and liffe the results show that relevant information is revealed during the trading hours of the imm and liffe but not the simex the interest rates of the three markets are cointegrated with a single common stochastic trend granger causality runs from the market that is placed in the last trading order within 24 hours in the vector error correction model and this causal relationship is shorter than one day an approach of variance decomposition and impulse response functions exploring the common factor in the cointegration system is employed analogous to the causality results the common factor is driven by the last trading market in the 24 hour trading sequence specifically each market while it is trading impounds all the information and rides on the common stochastic trend the overall results suggest that these three markets can be considered one continuously trading market

dynamic co movements of stock market returns implied volatility and policy uncertainty we examine time varying correlations among stock market returns implied volatility and policy uncertainty our findings suggest that correlations are indeed time varying and sensitive to oil demand shocks and us recessions

international listings and risk abstract this paper examines changes in volatility associated with the listing of us firms stocks on overseas exchanges implied volatilities are calculated for 40 firms that had exchange listed options at the time of their international listing the analysis documents significant increases in anticipated volatility following the overseas exchange listing while an industry matched control sample shows no meaningful changes in volatility we interpret the findings as supportive of the noice trading hypothesis jel f30

day of the week and intraday effects in stock returns abstract this study examines day of the week effects using hourly values of the dow jones industrial average we find that over the 1963 1983 period the weekend effect has sifted from characterizing active trading on monday to characterizing the non trading weekend over the early part of our sample period negative returns characterize each hour of trading on monday while the return from friday close to monday open is positive in the most recent subperiod monday average hourly returns after noon are all positive and the weekend effect is due to negative average returns from friday close to monday open

how does economic policy uncertainty drive gold stock correlations evidence from the uk abstractin this article we investigate the effects of economic policy uncertainty epu on correlations between the uk stock market and gold market we find that less certain economic policies result in lower correlations while more certain economic policies result in higher correlations the correlations are symmetric and show no structural breaks caused by the recent financial crisis the recent financial crisis has not changed epu effects on the correlations the effects of one positive one standard deviation shock of the logarithmic change rate of the epu on the correlations last approximately 19 months

forecasting losses on a liquidating long term loan portfolio abstract assessing the condition of financial institutions and valuation of loan portfolios in secondary markets require the estimation of exposure to losses on existing portfolios of long term loans data from a major u s financial institution were used to construct a forecasting model with markovian structure and nonstationary transition probabilities the model proved to be effective in representing changes in probability of default that occur as individual loans mature and accurate in forecasting aggregate defaults and losses on a nationwide portfolio of long term loans

u s stock market crash risk 1926 2010 abstract this paper examines how well alternate time changed levy processes capture stochastic volatility and the substantial outliers observed in u s stock market returns over the past 85 years the autocorrelation of daily stock market returns varies substantially over time necessitating an additional state variable when analyzing historical data i estimate various one and two factor stochastic volatility levy models with time varying autocorrelation via extensions of the bates 2006 methodology that provide filtered daily estimates of volatility and autocorrelation the paper explores option pricing implications including for the volatility index vix during the recent financial crisis

stock market structure and volatility the procedure for opening stocks on the nyse appears to affect price volatility an analytical framework for assessing the magnitude of the structurally induced volatility is presented the ratio of variance of open to open returns to closeto close returns is shown to be consistently greater than one for nyse common stocks during the period 1982 through 1986 tbe greater volatility at the open is not attributable to the way in which public information is released since both the opento open return and the close to close return span the same period of time instead the greater volatility appears to be attributable to private information revealed in trading and to temporaryprice deviations induced by specialist and other traders the implied cost of immediacy at the open is significantly higher than at the close other empirical evidence in this article documents the volume of trading at the open the time delays between the exchange opening and the first transaction in a stock the difference in daytime volatility versus overnight volatility and the extent to which volatility is related to trading volume

international transmission of stock market movements this paper investigates the international transmission mechanism of stock market movements by estimating a nine market vector autoregression var system using simulated responses of the estimated var system we i locate all the main channels of interactions among national stock markets and ii trace out the dynamic responses of one market to innovations in another generally speaking a substantial amount of multi lateral interaction is detected among national stock markets innovations in the u s are rapidly transmitted to other markets in a clearly recognizable fashion whereas no single foreign market can significantly explain the u s market movements also the dynamic response pattern is found to be generally consistent with the notion of informationally efficient international stock markets

asymmetric predictability of conditional variances we show that there is an asymmetry in the predictability of the volatilities of large versus small firms using both univariate and multivariate arma garch m parameterizations we find that volatility surprises to large market value firms are important to the future dynamics of their own returns as well as the returns of smaller firms conversely however shocks to smaller firms have no impact on the behavior of either the mean or the variance of the returns of larger capitalization companies article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the information value of failure predictions in credit assessment abstract this paper is concerned with the information value of failure prediction in the context of bank lending decisions it argues that earlier concerns about the methodology and robustness of classificatory models are given the volume of confirmatory studies no longer of practical significance instead the problem is whether reported classificatory performance provides information of value new information in a plausible ex ante decision situation in interpreting ex post evidence it appears that claimed information value is directly dependent on assumptions about factors which are neither specified nor testable within the conventional ex post experiment past claims for information value have used extreme values for these assumptions but it is argued that with plausible alternative assumptions the ex post evidence is also consistent with negative information value

are correlations of stock returns justified by subsequent changes in national outputs abstract in an integrated world capital market the same pricing kernel is applicable to all securities we apply this idea to the stock returns of different countries we investigate the underlying determinants of cross country stock return correlations first we determine for a given measured degree of commonality of country outputs what should be the degree of correlation of national stock returns we propose a framework that contains a statistical model for output and an intertemporal financial market model for stock returns we then attempt to match the correlations generated by the model with measured correlations our results show that under the hypothesis of market segmentation the model correlations are much smaller than observed correlations however assuming world markets are integrated our model correlations can be matched with observed correlations

a note on the transmission of public informtion across inetrnational stock markets abstract previous studies have established that public information cannot explain the decrease in return volatility during the closing of a stock exchange the present study shows that the failure of the public information hypothesis in explaining the trading nontrading volatility differential is merely a domestic phenomenon the manifestation of public information in an international setting is very different specifically the absence of price information due to the closing of the us market affects both volatility and trading volume in the canadian market

economic policy uncertainty in the us does it matter for the euro area abstract we investigate the effects of a us economic policy uncertainty shock on some euro area macroeconomic aggregates via structural vars we model the indicators of economic policy uncertainty recently developed by baker et al 2013 jointly with the aggregate price indexes and alternative indicators of the business cycle for the two above indicated economic areas according to our svars a one standard deviation shock to us economic policy uncertainty leads to a statistically significant fall in the european industrial production and prices of 0 12 and 0 06 respectively the contribution of the us uncertainty shock on the european aggregates is shown to be quantitatively larger than the one exerted by an euro area specific uncertainty shock

the valuation and market rationality of internet stock prices this paper provides an analysis of some existing as well as new evidence of the relation between market prices and fundamentals in the internet sector over the period january 1998 to february 2000 appealing to results across a broad class of outcomes we demonstrate a strong circumstantial case against market rationality in particular we investigate i the level of internet stock prices given their underlying fundamentals ii responses of stock prices to information based events and iii the volatility of internet prices we review several potential explanations of these phenomena including one based on heterogeneous beliefs across investors who are subject to short sales constraints we provide a discussion of the empirical evidence supporting this latter explanation copyright 2002 oxford university press

tax uncertainty and business activity abstract we investigate the extent to which uncertainties about tax policies affect business activities we develop a statewide tax uncertainty measure tu measure and show that it captures state corporate tax uncertainty by comparing adjacent counties across state borders we show that increasing tax uncertainty by one standard deviation a 30 increase in the tu measure leads to a 0 17 point per year decrease in the growth rate of establishments over two years the result holds after conducting a variety of robustness checks and is not likely to be driven by general state policy uncertainties

market efficiency around the clock some supporting evidence using foreign based derivatives abstract this paper examines whether information across international markets is rationally incorporated into stock prices we find that japanese nikkei index based futures traded in the u s provide complete information about contemporaneous overnight japanese returns moreover existing cross dependence between the u s and japanese stock index returns is subsumed by the information content of the derivative securities our findings cast doubt on trading models based on irrational traders who either overreact or only partially adjust to movements in foreign stock markets

lunch break and intraday volatility of stock returns an hourly data analysis of tokyo and new york stock markets abstract unlike the new york stock exchange the tokyo stock exchange shuts down for a lunch break this paper analyzes effects of this institutional feature on volatility of stock returns we show that the lack of trading itself reduces the volatility

information trading and stock returns lessons from dually listed securities this paper compares the intra day patterns on the nyse and amex of volatility trading volume and bid ask spreads for european and japanese dually listed stocks with american stocks of comparable average trading volume and volatility it is shown that the intra day patterns for these stocks are remarkably similar even though public information flows differ markedly across these stocks during the trading day in the early morning all stocks have higher volatility than later in the day but this phenomenon is most pronounced for japanese stocks and affects american stocks the least we argue that these patterns are consistent with markets reacting to the overnight accumulation of public information but are inconsistent with the view that early morning volatility can be attributed to monopolistic specialist behavior

the relationship between daily u s and japanese equity prices evidence from spot versus futures markets abstract the daily and overnight transmission of equity prices between the u s and japan is examined in this paper this study documents that the use of the opening value of an equity index to represent equity prices at the open is unlikely to be reliable and the calculated opening values of the nikkei 225 and especially the s p500 indexes mostly reflect prior days closing prices unlike prior studies this paper accounts for this problem of non synchronous trading at the open and finds that u s equity prices do not lead japanese equity prices as both u s and japanese opening equity prices reflect overnight price changes in the other market

stale prices and strategies for trading mutual funds we demonstrate that an institutional feature of numerous mutual funds funds managing billions in assets generates fund net asset values that reflect stale prices because investors can trade at these navs with limited transaction costs in many cases obvious trading opportunities exist these opportunities are especially prevalent in funds that buy japanese or european equities simple feasible strategies generate sharpe ratios excess return divided by standard deviation that are many times greater than the sharpe ratio of the underlying fund we illustrate the potential of the strategy for three vanguard group mutual funds a particular issue to keep in mind is that when the strategies are implemented the gains from these strategies are matched by offsetting losses incurred by buy and hold investors in these funds

private information and weekend volatility in the tokyo and new york stock markets the variance of new york stock index returns measured from the close of friday trading to the open on monday was more than three times higher when the tokyo stock market was open on the intervening saturday than the variance when the tokyo market was closed on saturday the variance of tokyo returns from the close of friday trading to the open on monday was over thirty seven times greater when the tokyo market traded on saturday this suggests that private information revealed through trading in tokyo not only raises volatility there but also increases volatility in new york

macroeconomic announcements and price discovery in the foreign exchange market this study shows that the dominance of the overlapping trading hours of london and new york in the price discovery of the eur usd and usd jpy markets only applies on days with u s announcements different from cai et al 2008 and wang and yang 2011 we highlight the informational advantage of local traders at the arrival of macroeconomic announcements in the local market and find that macroeconomic announcements affect the pattern of price discovery across different markets consistent with chen and gau 2010 and jiang et al 2012 we also examine changes in information shares before and after the announcement a significant increase in price discovery before the announcement suggests the possibility of information leakage while enhanced price discovery efficacy after the announcement suggests that prices gradually adjust to new information not just immediately respond to the arrival of announcements

trading breaks and asymmetric information the option markets abstract we find that weekend holiday and overnight trading breaks generate excessive perceived risk in the option markets presumably due to asymmetric information which in turn encourages uninformed option traders to postpone trading this perceived risk subsides after two days accompanied by an increase in the option trading volume and the underlying index s actual price volatility these results shed light on the informational role of index options and suggest that the theoretical models results regarding information processing and price discovery in the presence of private information are not limited to single stocks but also apply to the market as a whole

economic news and equity market linkages between the u s and u k abstract the source of equity market linkages between the u s and u k is investigated by focusing on intraday price movements of stock index futures contracts we document heightened u k return volatility at 11 30 a m and 1 30 p m gmt which corresponds to regular macroeconomic releases in the u k and u s respectively the response of u k equities in the half hour surrounding the u s announcements is significant and similar to price movements for u s equities to the same announcements these results support the hypothesis that the documented international equity market linkages are attributable to reactions of foreign traders to public information originating from the u s

return autocorrelations around nontrading days we document a pattern in the serial dependence of security returns around nontrading days the correlation of returns the second day after a weekend or holiday with returns the first day after is unusually low and in many return series is negative implying a reversal of price movements we also document unusually large positive return autocorrelations the last day before and the first day after weekends and holidays the pattern has existed in equity returns for over 100 years and also exists in several futures markets implying that the pattern is robust to alternative market microstructures article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the probability of bankruptcy a comparison of empirical predictions and theoretical models abstract the last decade has witnessed the development of many empirical models to predict corporate bankruptcy and of several bankruptcy theories this paper reviews and integrates these two strands of research and finds a substantial amount of overlap however the overlap is not perfect the paper presents a new theory of bankruptcy that appears to fit the data better the paper also suggests directions for future empirical and theoretical research

meteor showers or heat waves heteroskedastic intra daily volatility in the foreign exchange market this paper seeks to explain the causes of volatility clustering in exchange rates careful examination of intra daily exchange rates provides a test of two hypotheses heat waves and meteor showers the heat wave hypothesis is that the volatility has only country specific autocorrelation alternatively the meteor shower is a phenomenon of intra daily volatility spillovers from one market to the next using the garch model to specify the heteroskedasticity across intra daily market segments we find that the empirical evidence is generally against the null hypothesis of the heat wave using a volatility type of vector autoregression we examine the impact of news in one market on the time path of per hour volatility in other markets

the information content of end of the day index futures returns international evidence from the osaka nikkei 225 futures contract abstract employing a generalized autoregressive conditional heteroskedastic garch time series model this study investigates the relationship between end of the day eod osaka nikkei index futures returns and overnight spot returns for the period september 1988 through june 1991 a statistically significant positive relationship is found between the unexpected component of eod futures returns and overnight spot returns in addition the unexpected component of eod futures returns is positively related to trading period spot returns over the next two trading days these results suggest that eod futures returns reflect the information of informed traders which is partially revealed through trading the recent elimination of eod osaka nikkei futures trading has removed an important source of information dissemination

common volatility in the industrial structure of global capital markets abstract this paper investigates the nature of the volatility process among security prices for us europe and the pacific rim capital markets using a new data set that removes the problem of disparate index composition associated with aggregate stock market index series we use the common arch feature testing methodology recently developed by engle and kozicki journal of business economics 11 pp 369 380 1993 to examine the issue of a common volatility process among asset prices of nine industry groups from three economic regions of the world economy it is found that industry return series exhibit intra industry common time varying volatility process the evidence is consistent with the view that world capital markets are related through their second moments implying that a world common time varying variance specification seems to be appropriate in modeling asset prices while our empirical evidence suggests that investors can form constant variance portfolios by investing within an industry across regions they will be better off if they invest across regions and industries rather than diversify within an industry across different geographical regions that is the industrial mix of global investment portfolios accounts for a substantial proportion of the international diversification benefits finally our results appear to be consistent with roll journal of finance 47 pp 3 41 1992 view that the industrial structure of national stock exchange indices is important for explaining cross sectional return volatility differences

the effects of market segmentation and investor recognition on asset prices evidence from foreign stocks listing in the united states non u s firms cross listing shares on u s exchanges as american depositary receipts earn cumulative abnormal returns of 19 percent during the year before listing and an additional 1 20 percent during the listing week but incur a loss of 14 percent during the year following listing we show how these unusual share price changes are robust to changing market risk exposures and are related to an expansion of the shareholder base and to the amount of capital raised at the time of listing our tests provide support for the market segmentation hypothesis and merton s 1987 investor recognition hypothesis the globalization of u s capital markets has accelerated dramatically in the past decade increasing numbers of companies from overseas have chosen to either raise capital through global equity issues or prepare for future capital raising by way of cross listings on u s exchanges as of 1997 about 1 300 non u s companies have listed their shares for trading on the new york stock exchange nyse the american exchange amex the national association of securities dealers automation quotation nasdaq system or

the week end effect in common stock returns the international evidence this paper examines the daily stock market returns for four foreign countries we find a so called week end effect in each country in addition the lowest mean returns for the japanese and australian stock markets occur on tuesday the remainder of the paper answers four questions are seasonal patterns in foreign stock markets independent of those previously reported in the u s do japan and australia exhibit a seasonal one day out of phase due to different time zones do settlement procedures across countries bias week end effects does the seasonal pattern in foreign exchange offset the week end effect in stocks for americans investing overseas some of the most anomalous empirical findings in finance are associated with the sample distributions of daily common stock returns cross 1 french 2 gibbons and hess 3 and keim and stambaugh 4 have documented that the average return on friday is abnormally high and the average return on monday is abnormally low to our knowledge this so called day of the week effect or week end effect has yet to be explained because this anomaly has been reported primarily for u s stock returns it is appropriate to investigate whether similar results occur for other countries positive findings would strongly support the proposition that the weekly seasonal effect is a general world wide phenomenon rather than the result of a special type of institutional arrangement in the u s to shed more light on this proposition our paper examines stock market returns in the u k japan canada and australia since we find a week end effect in each country we can examine a set of interesting questions for example are these seasonals independent of the previously reported seasonal in the u s due to different time zones do far eastern countries exhibit a seasonal one day out of phase do different settlement procedures across countries influence weekend effects does the seasonal in foreign exchange fluctuations see mcfarland pettit and sung 7 and levi 6 offset the week end effect in stock market returns for americans investing overseas

conditional volatility skewness and kurtosis existence persistence and comovements abstract recent portfolio choice asset pricing value at risk and option valuation models highlight the importance of modeling the asymmetry and tail fatness of returns these characteristics are captured by the skewness and the kurtosis we characterize the maximal range of skewness and kurtosis for which a density exists and show that the generalized student t distribution spans a large domain in the maximal set we use this distribution to model innovations of a garch type model where parameters are conditional after demonstrating that an autoregressive specification of the parameters may yield spurious results we estimate and test restrictions of the model for a set of daily stock index and foreign exchange returns the estimation is implemented as a constrained optimization via a sequential quadratic programming algorithm adequacy tests demonstrate the importance of a time varying distribution for the innovations in almost all series we find time dependency of the asymmetry parameter whereas the degree of freedom parameter is generally found to be constant over time we also provide evidence that skewness is strongly persistent but kurtosis is much less so a simulation validates our estimations and we conjecture that normality holds for the estimates in a cross section setting we also document covariability of moments beyond volatility suggesting that extreme realizations tend to occur simultaneously on different markets

international arbitrage pricing theory an empirical investigation in this paper we test the arbitrage pricing theory apt in an international setting inter battery factor analysis is used to estimate the international common factors and the chow test is used in testing the validity of the apt our inter battery factor analysis results show that the number of common factors between a pair of countries ranges from one to five and our cross sectional test results lead us to reject the joint hypothesis that the international capital market is integrated and that the apt is internationally valid our results however do not rule out the possibility that the apt holds locally or regionally in segmented capital markets finally the basic results of both the inter battery factor analysis and the cross sectional tests are largely invariant to the nume raire currency chosen numerous authors notably solnik 21 grauer litzenberger and stehle 11 and stulz 24 have derived various versions of the international asset pricing model iapm under alternative views of the structure of international capital markets however only a few serious attempts have been made to test various versions of the iapm these tests are largely inconclusive see solnik 20 and stehle 23 apart from the problem stressed by roll 16 of identifying the world market portfolio previous tests of the iapms suffer from the technical problem of aggregating assets of national investors using different numeraire currencies differences in the numeraire arise from differences in consumption baskets in an environment characterized by exchange rate uncertainty in a fruitful attempt to extend the arbitrage pricing theory apt of ross 18 to an international setting solnik 22 derives an international arbitrage pricing theory which is largely devoid of the aforementioned difficulties and thus more amenable to empirical testing 1 as shown by solnik testability of the apt in an

trading and returns under periodic market closures this paper studies how market closures affect investors trading policies and the resulting return generating process it shows that closures generate rich patterns of time variation in trading and returns including those consistent with empirical findings 1 u shaped patterns in the mean and volatility of returns over trading periods 2 higher trading activity around the close and open 3 more volatile open to open returns than close to close returns 4 higher returns over trading periods than over nontrading periods 5 more volatile returns over trading periods than over nontrading periods it also shows that closures can make prices more informative about future payoffs we model a competitive stock market with periodic closures in which investors trade for both allocational and informational reasons we use the model to study how market closures intrinsically affect investors trading behavior and the return generating process the purpose of this analysis is to increase our understanding of the time variation in security trading and returns that are associated with regular market closures such as the intraday and intraweek patterns in stock returns volatility and trading volume we consider a stock market in which the exogenous information flow is homogeneous over time and the market closes periodically when the market is open investors trade the stock either to rebalance their overall portfolio of assets which also includes other illiquid assets or to speculate on future stock payoffs using their private information in particular investors adjust their asset portfolio by trading the stock in order to hedge the risk of illiquid assets we refer to these trades as hedging trades and those motivated by private information as speculative trades when the market is closed hong is from the graduate school of business stanford university and wang is from the sloan school of management massachusetts institute of technology and nber the authors thank jennifer huang for programming assistance and an anonymous referee for many valuable suggestions they also thank glenn ellison john heaton craig holden andrew lo steve slezak jeremy stein rene stulz the editor the nber asset pricing lunch group and par

volatility information and double versus walrasian auction pricing in us and japanese futures markets abstract this study empirically examines volatility in us and japanese commodity futures markets the us futures market comex is double auction with continuous trading whereas the japanese futures market tocom was walrasian with discrete trading until april 1991 we find intraday volatility for gold futures contracts to be significantly higher on comex than tocom throughout the sample period and is attributable to differences in information flows and market micro structures evidence is also provided that exchange volume conveys information both within and across markets which is consistent with the french and roll 1986 french k r roll r 1986 stock return variances the arrival of information and the reaction of traders journal of financial economics 17 5 26 private information based rational trading model finally daily variance and autocorrelation estimates within comex are consistent with the extant literature on equity markets

volatility in the foreign currency futures market we examine the volatility implications of around the clock foreign exchange trading with transaction data on futures contracts from the chicago mercantile exchange and the london international financial futures exchange we find higher u s european and u s japanese exchange rate volatilities during u s trading hours and higher european cross rate volatilities during european trading hours while the diclosure of private information through trading may partly explain these volatility patterns we conclude that the increased volatility is more likely driven by macroeconomic news announcements an analysis of inter and intraday data also reveals that volatility increases at times that coincide with the release of u s macroeconomic news article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

components of short horizon individual security returns abstract in this paper we present a simple model which relates security returns to three components an expected return a bid ask error and white noise the relative importance of the various components is empirically assessed and the model s ability to explain the various time series properties of individual security and portfolio returns is tested time varying expected returns and bid ask errors are found to explain substantial proportions up to 24 of the variance of security returns we also reconcile the typically negative autocorrelation in security returns with the strong positive autocorrelation in portfolio returns

where does the meteor shower come from the role of stochastic policy coordination abstract this paper examines the intra daily volatility of the yen dollar exchange rate over three different regimes from 1979 to 1988 which correspond to different degrees of international policy coordination in each regime we test for heat wave vs meteor shower effects the heat wave hypothesis assumes that volatility has only country specific autocorrelations while the meteor shower hypothesis allows volatility spillovers across markets meteor shower showers can be caused by stochastic policy coordination or by gradual release of private information the rejection of the heat wave hypothesis in the early 1980s discredits the stochastic policy coordination interpretation

international spillovers of policy uncertainty using the baker et al 2013 index of policy uncertainty for six developed countries this paper estimates spillovers of policy uncertainty we find that spillovers account for slightly more than one fourth of the dynamics of policy uncertainty in these countries with this share rising to one half during the financial crisis the us and uk are responsible for a large fraction of the spillovers since the financial crisis while the remaining countries are all net receivers of policy uncertainty shocks during and after this period

changes in institutional ownership and stock returns assessment and methodology although the relation between quarterly changes in institutional investor ownership and contemporaneous stock returns is well documented the source of the relation remains unclear because institutional ownership data are unavailable at higher frequencies in this study we develop a method to generate estimates of higher frequency covariances when one variable is observed at lower frequencies e g quarterly changes in institutional ownership and monthly stock returns our method provides evidence that institutional trading has both temporary and permanent price effects and that the latter is associated with information effects

modelling round the clock price discovery for cross listed stocks using state space methods u s trading in non u s stocks has grown dramatically around the clock these stocks trade in the home market in the u s market and potentially in both markets simultaneously we develop a general methodology based on a state space model to study 24 hour price discovery in a multiple markets setting as opposed to the standard variance ratio approach this model deals naturally with 1 simultaneous quotes in an overlap 2 missing observations in a nonoverlap 3 noise due to transitory microstructure effects and 4 contemporaneous correlation in returns due to market wide factors we apply our model to dutch stocks cross listed in the united states our findings suggest a minor role for the new york stock exchange in price discovery for dutch shares in spite of its nontrivial and growing market share

bank strategies toward firms in decline abstract small firms are usually in constant need of funds in addition when they are in decline it puts them in a weak and dependent relationship with a commercial bank the strategy followed by the bank toward these firms is a powerful influence on their success in turnaround and their very existence in order to identify generic strategies followed by banks this exploratory study analyzed data on bank responses to 192 client firms these firms have been classified as problem loans i e there is an actual default or the bank perceives a potential default on their loans as this problem in the firm arises largely out of weakness in its primary sources of payment which is operations problem loans are firms in the early stages of decline using factor analysis four distinct strategies toward these firms were identified 1 managerial involving efforts to influence strategy and operations of the firm through suggestions and recommendations 2 financial involving efforts to safeguard the security interests of the bank by seeking additional collateral and guarantees 3 legal involving recovery of funds through courts and 4 restructuring including efforts to improve capitalization the firms were clustered into six groups using factor scores thumbnail profiles of each cluster showed the groups to be distinct finally three sets of contextual variables representing firm loan characteristics event triggers and the bank client relationship were used to discriminate among the clusters of firms the variables found to be significant in discriminating among the groups and thus impacting the strategies followed toward them included firm size the secured status of the loan the bank s perception of whether the decline was due to internal or external reasons severity of the problems facing the firm and cooperation of the client significantly the extent of loss incurred by the firm and years as a client did not make a difference to the strategy used where reasons for decline were largely external to the firm financial and merger strategies were preferred when the causes were internal managerial and legal strategies were important firm size was significant banks were less inclined to adopt managerial and financial strategies toward small as against medium sized firms these findings point to important lessons for managers in their dealings with banks banks generally prefer to work with clients toward a turnaround rather than resorting to legal means of recovery to take advantage of this attitude firms need to demonstrate cooperation to secure favorable terms as long as the bank s funds are fully secured moreover because bank strategies are dependent on their perceptions of the causes of the problems managers need to recognize the importance of providing appropriate information to create the right perception
