Abstract:
A dynamic and flexible method, system and apparatus for managing index mutual funds and index exchange traded funds (ETFs) through using and measuring Relative Strengths and Alphas of the underlying index components to periodically reweight the underlying index components. These reweightings are used in the daily rebalancing of the respective index mutual funds/ETFs to decrease market risk and seek to improve returns above those of the statically weighted index. The disclosure demonstrates how various mutual fund/ETF indexes are flexibly weighted according to Relative Strength and Alpha calculations each standing alone or used in combination. The determination of the relative weights of Relative Strength and Alpha can be made periodically by management using a back testing and computer optimization process. After periodic determination of index component weights the mutual fund/ETF index portfolio rebalancing can occur daily, multiple intervals intraday, or any interval which conforms to regulatory requirements. Portfolios suitable for this method and apparatus include equity, bonds, or hybrids (equity and bonds).

RELATED APPLICATION  
       [0001]     This Application claims the benefit of U.S. Provisional Application No. 60/625,867, filed on Nov. 8, 2004. 
     
    
     FIELD OF THE INVENTION  
       [0002]     This invention relates to a system and method that manages a fund of financial instruments based on relative strength, weighting, alphas and rebalancing.  
       BACKGROUND OF THE INVENTION  
       [0003]     Mutual Funds, which had their origin in 1925, have been classified into one of two categories. The first category is those mutual funds that are actively managed portfolios that consist of stocks specifically chosen for that portfolio. Fundamental analysis (evaluation of a company&#39;s earning prospects) was used in the decision process when creating and managing this category of mutual fund. The second category is mutual funds that consist of an index that was created and maintained by entities such as Standard and Poor and Dow Jones Indexes. These indexes are generally recognized by the marketplace as proxies for the sector of the market that they represent. Investors believe that a particular sector or the market will do well in the future or simple want broad exposure to the market with great diversification among stocks purchase these indexes and hold for various periods of time.  
         [0004]     Exchange Traded Index Funds (ETFs), a more recent innovation coming into existence in the last 10 years, seek to track various indexes, are traded on an established exchange (currently primarily the New York and American Exchanges). ETFs offer the investor the opportunity for real time exchanges in and out of a number of recognized indexes through use of a broker. ETFs have a structure that allows investors more numerous opportunities for exchanges and relatively lower expense ratios but investors often face decrease liquidity of their shares and incur commission expenses for exchanges in and out that are absorbed by equivalently structured mutual funds.  
       DESCRIPTION OF INDEXES  
       [0005]     Indexes are most commonly market capitalization (free floating shares) weighted. That is, the index components with the largest total market capitalization are weighted the heaviest within the index. Some indexes are equal weighted with each component assigned an equal weight within the index. At least one index is price weighted with the highest priced security component receiving the greatest weight and the lowest priced component receiving the least weight. The common feature is that these market indexes have permanent fixed weightings that are assigned by the sponsoring entity and managed in a completely passive manner. The mutual fund companies/ETFs who use these indexes for their funds seek to emulate the stated fixed weightings exactly regardless of changing market conditions or changing performance of the indexes components.  
         [0006]     The sponsoring companies for these indexes usually make additions or deletions to their indexes yearly or less frequently by removing some old names and adding new names while maintaining the Index&#39;s fixed weightings. The reasons for these deletions are usually due to poor performance by index components. The reasons for index additions include a company with strong growth and rising prospects within its index sector in terms of company size or importance. These changes are made by the sponsoring index companies on an as needed basis.  
         [0007]     Investors can own an index that correlates with the broad market (i.e. S&amp;P 500), large cap old line industrial stocks (Dow Industrials), and a broad market sector (i.e. Dow Transportation or Dow Utilities). Investors can choose to own a more defined and narrow market sector (i.e. SOX semiconductor index, XAU gold index, XOI Oil index, Morgan Stanley Internet Index, GSTI Multimedia Networking Index). In addition, indexes have been created to give exposure to certain regions of the world (Europe Dow Jones Stock 50, Emerging Markets Index) or individual large countries (i.e. Germany DAX 30, France—CAC40, Great Britain—FTSE 100). Country funds also include many smaller geographical regions (i.e., Netherlands AEX Index—Amsterdam Stock Exchange, Spain IBEX 35 index Madrid Stock Exchange, Brazil—Bovespa—BVSP index, Australia—All Ordinaries—AORD Index). Indexes known as style indexes have also been created to invest in a particular market cap size stock (i.e. Russell 2000 small capitalization, mid cap S&amp;P 600). The above are examples but not a complete list of index types.  
         [0008]     Examples of Bond Index Funds can include Corporate Bonds (short, medium, and long term), High Yield (junk bonds), mortgage-backed bonds (Ginnie Maes), Treasury Bonds as quoted by primary Treasury bonds dealers, Tax Free Municipal Bonds, Special Agency. Local, and State issue bonds.  
         [0009]     Real Estate Investment Trust constituents are another example to apply this system.  
         [0010]     Index funds provide several benefits to investors. A large number of security components provide portfolio diversity reducing unique stock risk within a portfolio. In addition, fairly large sums of money can be rapidly invested in indexes because of the large number of securities in the index that absorb the capital with negligible price slippage.  
         [0011]     To date index investing has remained a completely passive task. A mutual fund company/ETF currently seeks to offer its customers an exact replication of an index&#39;s performance by replicating the security components exactly as well as replicating the fixed weighted structure presented by the creator of the index. (i.e., Dow Jones Indexes and Standard and Poor).

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0035]     An alternative to actively managed mutual fund and completely passively managed mutual fund index portfolio would be to create a third category of mutual fund. The mutual fund would be described as a semi-passive index fund portfolio structure. No active fundamental research would be done on any securities eliminating huge research costs. All components of the index would be retained. However, the mutual fund&#39;s/ETF index components would be weighted and reweighted periodically to emphasize index component securities which are predicted to appreciate faster in the future than the underlying index to which they belong. The index would under emphasize index component securities, which are predicted to under perform the underlying index to which the security component belongs. By employing this process diversification and the relatively low management cost of indexes as compared to actively managed funds would be maintained through use of computers to optimize the weightings. The method and process to achieve these relative weightings and reweighting is described.  
         [0000]     Method and Process  
         [0036]     The method describes a way for mutual funds/ETFs to balance and rebalance the fund indexes in a manner to achieve superior price performance in comparison to the statically weighted indexes. The US Security and Exchange Commission currently requires mutual funds to balance once a day (ETFs real time) by pricing all mutual funds and providing the index&#39;s owner with a value know as net asset value (NAV). More frequent intraday balancing can and does occur. Currently, Fidelity Sector Funds balances their sector funds each hour establishing a net asset value for these indexes at each interval. The fund family/ETF creator using this balancing process will most likely continue to adjust index as the sponsoring index company makes periodic additions or deletions to the index. However, the Fund/ETF may also choose not to do so.  
         [0037]     Since this invention describes a process for variable weightings and at variable time intervals of index mutual funds/ETFs, a third category of Mutual Fund investing and a second category of ETF is described. By systematically overweighting better performing index components and systematically underweighting lesser performing index performance and using computers to optimize the weightings and the timing of reweightings the goal of increased index fund performance can be realized for minimal relative costs while maintaining security diversification and index type liquidity enabling relatively large amounts of capital to enter and exit the index with little price slippage.  
         [0038]     Two technical indicators (Relative Strength and Alpha) focusing exclusively on price would be used to determine daily rebalancing weights of the components. The relative strength and alpha numbers would be determined at fixed intervals from as often as one day to as long as one year. Computer optimization through both back testing and forward testing can be used to help Index fund management to determine the precise time interval and component weightings to use.  
         [0039]     A relative strength (and/or alpha) number would be assigned to each component and compared to either the underlying index of which the component is a member or a broader index (i.e. S&amp;P 500, Dow Industrials), which the index manager wishes the component performance to be compared. A security rising faster than the underlying index being compared to would have a relative strength number or greater than 50 and less than 100. A securities price rising slower than the index would have a relative strength number of less than 50 and greater than 1. Thus, all index components would be assigned a periodic ranking of from 1 to 99 at specific time intervals determined by the index managers.  
         [0040]     The index portfolio would be more heavily weighted with stock components having higher relative strength numbers that are rising and underweighted with stock components which have low RS number and all falling. A change in reweighting rebalancing intervals would occur periodically. Daily index rebalancing according to net buying and selling from customers orders would occur as usual to establish a daily NAV (net asset value) as currently required by government regulators.  
         [0041]     A variable number of time periods can be used to recalculate the relative weightings. (i.e., weekly time periods). Periodic review of relative weightings can be done by fund management (i. e., Evaluation Frequency can be Yearly, Quarterly, Monthly, Bi-Weekly, or Daily).  
         [0042]     Computers and software can be used to assist in determining the ideal weightings and the frequency of weightings evaluations by management through use of an optimization process, which includes back testing, a process is used to test various RS and Alpha Weightings to determine an optimal weighting.  
         [0043]     An additional indicator, known as alpha, would be calculated on every index component and used in the index component weighting decisions. These formulas for alpha and relative strength would be reduced to computer code. The computer code in the form of usable software would be used to determine optimized component weighting levels and as well as optimized time intervals to review the weightings and suggest the shift in relative strength and alpha weighting to be shifted among the index components  
         [0044]     The amount of index component purchases and/or sells each day would be a function of both predetermined stock weightings and the index owners demand to buy and this particular index on a particular day.  
         [0045]     Relative Strength is calculated with a Relative Strength Index (RSI) Equation:
 
 RSI= 100   −[100/1 +RS], 
 
         [0046]     where Relative Strength (RS)=Average of x # of day&#39;s closes up/Average of x # of day&#39;s close down.  
         [0047]     For an example of x=14 days, the procedure is as follows: 
        (1) Obtain the sum of the UP closes for the previous 14 days and divide this sum by 14. This is the average UP close.     (2) Obtain the sum of the down closes for the previous 14 days and divide this sum by 14. This is the average down close.     (3) Divide the average UP close by the average DOWN close to obtain the Relative Strength (RS).     (4) Add 1.00 to the RS.     (5) Divide the result obtained in Step 4 into 100.     (6) Subtract the result obtained in step 5 from 100. This is the first RSI.        
 
         [0054]     Moving forward, it is only necessary to use the previous average UP close and the previous average DOWN close in the calculation of the next RSI. This procedure alters the above steps (1) and (2) as follows. 
        1. To obtain the next average UP close, multiply the previous average UP close by 13 and add to this number today&#39;s UP close and divide the total by 14.     2. To obtain the next average down close, multiply the previous average DOWN close by 13 and add to this number today&#39;s DOWN close and divide the total by 14. 
 
 Steps (3), (4), (5) and (6) are the same as the initial RSI. 
       
 
         [0057]     The following Relative Strength (RS) Weighting examples are for a Normal Weighting of 1.0:  
       EXAMPLE 1  
       [0058]     95% or higher RS rating weighted 3×normal weighting  
         [0059]     5% or lower RS rating weighted 0.25×normal weighting  
       EXAMPLE 2  
       [0060]     90%-95% RS rating weighted 2.5×normal weighting  
         [0061]     5%-10% RS rating weighted at 0.33×normal weighting  
       EXAMPLE 3  
       [0062]     85% -90% RS rating weighted 2.0×normal weighting  
         [0063]     10% -15% RS rating weighted 0.50% normal weighting  
       EXAMPLE 4  
       [0064]     80%-85% RS rating weighted 1.5×normal weighting  
         [0065]     15%-20% RS rating weighted 0.75% normal weighting  
         [0066]     For these examples, calculations and adjustments to list are made on a weekly basis. Quarterly reevaluation of weightings are made with computer optimization.  
         [0000]     Definition of Alpha and How it is Used  
         [0067]     ALPHA, Raw ALPHA, Weighted ALPHA, and Raw Weighted ALPHA. The Alpha is a measure of how much a stock has risen or fallen, typically over a one-year period. However, alpha can also be defined as any absolute against an index (broad or narrow) for a much shorter period of time. For example, alpha could be expressed as 15 days positive price increase either against a stock price itself or against an underlying index. Of course an explanation of how alpha is currently defined should accompany the alpha numbers calculated.  
         [0068]     Original research of alpha was restricted to large cap stocks, so the corresponding rise in the S&amp;P 500 index was subtracted. There are a number of stocks that do not fit well into any category and others that fit into more than one category. Our calculations will be presented either without subtracting any index or subtracting the index with which they are more closely identified.  
         [0069]     If no index alpha is subtracted then the term Raw Alpha is used.  
         [0070]     Weighted Alpha: First how much a stock has changed in a one-year period is determined. Then more weight is assigned at the most recent period and less weight (for example, 0.5) at the beginning of the period. A weighted alpha is a measure of one-year growth with an emphasis on the most recent activity and then subtracting the growth of its underlying index.  
         [0071]     Raw Weighted Alpha is a Weighted Alpha without subtracting the underlying index. The defined the default time period for alpha calculations is one year.) 
        A stock that has risen over the one year period will have a positive Raw Weighted Alpha.     stock that has not changed or has changed very little will have a zero or small Weighted Alpha.     stock whose price has dropped over the period will have a negative Weighted Alpha. 
 
 Subtracting the change of an index from alpha will lower the alpha number but lower it on a relative basis as long as the same index is used in comparison or stock alphas. 
       
 
         [0075]     Characteristics of Alpha include the following: 
        Alpha can be measured for any time period (but most typically for a one year time frame)     Alpha can be a measured of the security against itself     Alpha can be a measured of the security against a specified underlying index     Alpha can be a measured that is either weighted equally among the days, weeks, months, or years for which it is measure or weighted more heavily toward the more recent times frame periods either days, weeks, months, or years.        
 
         [0080]     The following are examples of Relative Weightings of Alphas, for a one-year period of Alpha Weightings:

       [0093]     90 day alpha weighted most recent month×2. Months 2 and 3 both×1. Measured against the security itself.  
         [0094]     The following are examples of use of RS and Alpha in combination:  
       EXAMPLE #1  
       [0095]     Both RS and Alpha 95% or greater for the Index group evaluated Weighted at 3×normal weightings  
       EXAMPLE #2  
       [0096]     Both RS and Alpha 90% or greater for the Index group evaluated Weighted at 2.5×normal  
       EXAMPLE #3  
       [0097]     RS greater than 95% and Alpha greater than 90% for Index group evaluated Weighted at 2×normal weightings  
       EXAMPLE #4  
       [0098]     RS greater than 80% and Alpha greater than 90% for Index group evaluated Weighted at 1.5×normal weightings  
       EXAMPLE #5  
       [0099]     RS greater than 85% and an absolute 15 day positive Alpha of 0.15 as compared to the underlying index group.  
       EXAMPLE #6  
       [0100]     RS greater that 75% and an absolute 30 day positive Alpha of 0.25 as compared to the underlying security itself.  
         [0101]     The method describes the use of alpha (with a corresponding rise of an index subtracted), Raw alpha (no index subtracted), Weighted Alpha (with a corresponding rise of an index subtracted) and time periods weighted to variable specifications, and Raw Weighted Alpha (no index subtracted) and weighted to variable specifications as depicted in the above examples.  
         [0102]     Mutual Fund/ETF Indexes can be weighted by using RS and Alpha as determinates of the relative weightings either alone or in combination.  
         [0103]     Change of Weightings in Relative Strength (RS) and Alpha. A flexible process where management can change index weightings using RS and/or Alpha at any time is described. Computer optimization is a very important tool in evaluating the weighting changes. Some reasons that may suggest that a weighting change is needed include changes in the characteristics of the market as a whole. Such as change in market from trending up to trending sideways, market from trending sideways to trending down, market trending up to market trending down, market trending down to market trending up, price volatility changing from high to low or price volatility changing from low to high.  
         [0104]     Although a quarterly review of mutual fund index/ETF weightings with the aid of a computer optimization process can provide a time benchmark, the frequency of review is flexible can be done as frequent or infrequently as management deems and in sync with current market conditions. Index weightings can be done using RS (relative strength) exclusively, or using alpha (clearly defined) exclusively. Index weightings also can be determined using RS and Alpha together. Using the power of the computer processing chip and software thousands of computations and permutations can be rapidly calculated to aid in determining the optimal index weightings for the current market environment of equity, bonds, and or hybrid (equity and bond) portfolios.  
         [0105]     The present invention provides: 
        Index Portfolios weightings modifications using Relative Strength of the index components against the underlying index or against another broad index (i.e. S&amp;P 500)     Index Portfolio weightings modifications using Alpha of the individual index components against the underlying index or against another broad index (i.e. S&amp;P 500)     Index Portfolios weightings modifications using Relative Strength and Alpha in combination at various weighting percentages. (i.e. Relative Strength 50% and Alpha 50%)     Alpha may be defined as Alpha, Raw Alpha, Weighted Alpha, or Raw Weighted Alpha in terms of how alpha is calculated and used in the formula for index portfolio weightings (see definitions above)        
 
         [0110]     Index and market products suitable for use with the weighting modification system of the present invention, for example, include the following: 
        Index Portfolios including Mutual Index Funds (Equity, Bond, Hybrid)     Exchange Traded Funds (Equity, Bonds, and Hybrid).     Real Estate Investment Trusts (REITs)     Traditional Bond Portfolios        
 
         [0115]     Referring now to  FIG. 1 , a system  21  of the present invention comprises a fund manager computer  20 , a client or investor computer  22  and a data source  26  that are interconnected via a communication network, shown as an Internet  24 . Fund manager computer  20  may be a single computer as shown or may in alternate embodiments be comprised of one or more computers. Client computer  22  is a computer used by one or more investor clients to obtain investment information from fund manager computer  20 . It will be appreciated by those of skill in the art that client computer  22  is one of many client computers that communicate with fund manager computer  20  via Internet  24 . Data source  26  comprises one or more databases that provide data concerning securities, particularly those contained in the portfolio being managed by fund manager computer  20 .  
         [0116]     Referring to  FIG. 2 , fund manager computer  20  comprises a processor  32 , one or more input/output (I/O) units  34 , at least one communication unit  36  and a memory  38  that are all interconnected by a bus  40 . I/O units  34 , for example, may include input devices, such as a keyboard, a mouse or other suitable input device and output devices, such as a display, a printer and any other suitable output device.  
         [0117]     Memory  38  may comprise one or more types of memory, such as random access, read only, flash, disk drives of any type and the like. Stored in memory  38  are a plurality of programs that include a fund management program  42 , a browser  44  and an operating system  46 . It will be apparent to those skilled in the art that many other programs may be resident in memory  38 .  
         [0118]     In operation, processor  32  executes or runs a plurality of instructions of fund management program  42  to provide the functionality of the method and system of the present invention. Processor  32  cooperates with browser  44  and communication unit  36  to communicate with data source  26  and client computer  22  via internet  24 .  
         [0119]     It will be appreciated by those skilled in the art that client computer  22  may be similar to computer  20 , but would not be provided with fund management program  42 .  
         [0120]     Referring to  FIG. 3 , fund management program  42  comprises a program process  60  for index component weighting and frequency of data input. Process  60  when initiated at start  61  obtains at step  62  from data source  26  prices of the index components contained in the fund portfolio. This price data may be obtained from recognized major exchanges (for example, New York Stock Exchange, American Exchange, NASDAQ, CBOE or others) where the index components are traded. A process  66  is run to obtain data (e.g., prices of index stock components) for an index and index product as originally structured , for example, Standard and Poor indexes, Dow Jones indexes and/or others.  
         [0121]     At step  64 , the index component price data obtained by step  62  is processed to provide prices of the index components at a specified periodicity, e.g., daily, hourly, twice a day or other period.  
         [0122]     At step  70 , the fund management personnel evaluate rules and strategies of the fund with the aid of computer optimization assistance. Any needed changes, such as weighting for relative strength and/or alpha, are input via I/O units  34 . At step  74 , based on input from step  70 , weighting is assigned to the relative strength and alpha of the index components list provided by step  72 . At step  68 , the relative strength and alpha calculations are performed for the index components based on the price data provided from step  64 . At step  76 , the index list is compiled based on a sort from highest to lowest relative strength and/or alpha according to any strategy decision entered via step  70  by management personnel. At step  78 , output reports of the compiled list are generated for review by management. Process  60  ends at step  80 .  
         [0123]     Referring to  FIG. 4 , fund management program  42  comprises a program process  100  for determining index weightings. Upon initiation at step  102 , step  104  waits for management input regarding index component weighting. Management&#39;s recommendations may be developed with the aid of computer optimization. Step  106  determines the relative weightings for relative strength and/or alpha. For example, index components in the upper 10% are weighted by 2.0 and index components in the lower 10% are weighted by 0.5.  
         [0124]     Step  108  determines the time-frame to be used in managing the portfolio of index components. For example, a weekly definition use 5 days of market data or less based on holidays or other circumstances. The determinations made by steps  106  and  108  may be aided by computer optimization input provided by steps  110  and  112 , respectively.  
         [0125]     Step  114  compiles a weekly list using a sort of the index components based on relative strength and/or alpha data provided by step  106  and frequency data (e.g., weekly) provided by step  108 . Step  116  generates a new index component list for fund rebalancing purposes, which may be executed based on shareholder buy and sell data. Process  100  ends at step  118 .  
         [0126]     Referring to  FIG. 5 , fund management program  42  comprises a program process  130  for sorting the index list. Process  130  can be run at any suitable intervals. For example process  130  can be run daily and at multiple intervals intra day. Upon initiation at step  132 , step  134  assigns relative strengths and/or alphas for the current weekly list sorted from highest to lowest. Step  136  sorts the new weekly list provided by step  134  by relative strength and/or alpha. Step  138  provides relative weights based on input from fund management personnel. The relative weights, for example, may be a weight of 2.0 for the top 10% of the components and 0.5 for the bottom 10% of the components in the list. The list sorted by step  136  is further sorted by step  140  by relative weights and amounts for use of index component purchases and sales. Step  144  provides a net amount of new funds from customers for buys and sells of the fund. Step  142  calculates the number of shares of each component to be bought or sold based on the available net customer funds and generates a new list with the share numbers of the components to be bought or sold. Process  130  ends at step  146 .  
         [0127]     Referring to  FIG. 6 , fund management program  42  comprises a program process  160  for a one day balancing cycle. Upon initiation at step  162 , step  164  calculates the relative number of shares of each component to be bought or sold based on new relative weight with the available net customer funds from purchase and sale of fund shares. Step  166  generates a fund list of index components for purchase and/or sale prior to market purchase and sale cut off time. Step  168  sends the net buy and sell orders for the index components to the appropriate exchanges. For example, if the NAV (net asset value) of an open ended index fund is $100 per share, and the funds investors wish to buy $1,000,000 of this index fund for a current day, a total of 10,000 new shares of this fund would be created for the current day. Step  170  generates a new portfolio at the end of the trading day by (NAV) after balancing.  
         [0128]     Step  180  comprises the daily input of customer orders for purchase and sale of fund shares from a client computer  22  or via other communication, such as telephone, facsimile and the like. Step  186  captures the daily customer input of net buy and/or sell orders of fund shares. Step  188  calculates net available funds from the net customer purchases and sales of fund shares. Step  178  generates a fund list of index components for purchase and/or sale prior to market purchase and sale cut off time for the next day. Process  160  ends at step  190 .  
         [0129]     Referring to  FIG. 7 , fund management program  42  comprises a program process  200  for a daily rebalancing cycle. Process  200  is preferably used on a daily basis. In alternate embodiments, process  200  can be run according to any desired frequency of occurrence. For example, process  200  could be run twice a day, hourly, or every  30  minutes throughout a market day. Upon initiation at step  202 , step  204  determines at the start of the day whether the relative weights remain the same or have been adjusted for the new trading session. Step  206  generates the index list prior to market purchase or sale cut off time (e.g., 3:45 EST) based on the previous day&#39;s NAV. Step  210  captures customer orders for purchase and sale of fund shares from all sources. Step  212  calculates the net dollars available for purchase or sale of index components based on the captured customer orders. Step  208  generates and sends a list of index component buy and sell orders to the trading department for execution prior to the end of the trading day. Step  214  generates a new portfolio at the end of day after rebalancing. Step  216  comprises customers checking their account via Internet  24 . Process  202  ends at step  218 .  
         [0130]     Referring to  FIG. 8 , fund management program  42  comprises a program process  230  for a real time rebalancing cycle for EFTs. Process  230  is preferably used on a daily basis. In alternate embodiments, process  230  can be run according to any desired frequency of occurrence. For example, process  230  could be run twice a day, hourly, or every  30  minutes throughout a market day. Upon initiation at step  232 , step  234  determines at the start of the day whether the relative weights remain the same or have been adjusted for the new trading session. Step  236  generates the index list prior to the beginning of the trading session and balancing after the last trade of the previous trading day. Step  240  depicts customer orders for purchase and sale of the ETF shares throughout the trading day. Step  238  depicts the exchange upon which the ETF is listed. Step  242  adjusts the ETF list of fund components in real time as to the total number of shares held by the ETF. Step  244  depicts investors checking their account information for any updates posted by their respective brokers. Step  246  generates a new portfolio index list after the trading session ends. Process  230  ends at step  248 .  
         [0131]     Referring to  FIG. 9 , fund management program  42  comprises a program process  260  for a one week cycle with daily rebalancing and weekly adjustment of weighting. Process  260  comprises a day 1 week 1 process  262 , a day 2 week 1 process  264 , day 3 week 1 process, day 4 week 1 process and a day 5 week 1 process  266 . Day 1 week 1 process  262 , day 2 week 1 process  264 , day 3 week 1 process and day 4 week 1 process are substantially identical, so only day week 1 process  262  will be described in detail. Day 2 week 1 and day 3 week 1 processes are not shown on the drawing, but are indicated by the dashed line between day 2 week 1 process  264  and day 5 week 1 process  266 .  
         [0132]     Upon initiation at step  270 , step  272  calculates net dollars or available funds based on customer orders to sell and buy fund shares captured by step  274 . Step  276  allocates the net available funds to the components of the portfolio of the previous trading day (e.g., day 5 or the preceding week). Step  278  rebalances the portfolio based on the component characteristic (relative strength and/or alpha) as described above for  FIGS. 5 and 7 . Step  280  generates a new portfolio, which serves as an input to day 2 week 1 process  264 . Step  282  reconciles the investor accounts per the net asset value (NAV) at the close of trading for day 1 week 1. Step  284  enables investors to access their accounts via Internet  24 .  
         [0133]     Day 5 week 1 process  266  at step  302  calculates net dollars or available funds based on customer orders to sell and buy fund shares captured by step  304 . Step  306  allocates the net available funds to the components of the portfolio of the previous trading day (e.g., day 4 week 1). Step  308  rebalances the portfolio based on the component characteristic (relative strength and/or alpha) as described above for  FIGS. 5 and 7 . Step  312  reconciles the investor accounts per the net asset value (NAV) at the close of trading for day 5 week 1. Step  314  enables investors to access their accounts via Internet  24 .  
         [0134]     Based on customer orders for purchase and sale of fund shares over a weekend or holiday, step  324  calculates net dollars or available funds based on customer orders to sell and buy fund shares captured by step  322 . Based on these net available funds, orders are sent to market. Step  316  captures any input of relative weight entered by an operator or a computer optimization. Reweighting can be done periodically, e.g., quarterly or other period, or upon the occurrence of some significant event, such as, an earthquake, a hurricane, act of war and other events. Step  320  provides a relative weighting based on any input from step  316 . This weighting can be unchanged or changed based on the determination of step  316 . Step  310  generates a new portfolio, based on the weighting provided by step  320 . Step  320   
         [0135]     Referring to  FIG. 10 , fund management program  42  comprises a program process  400  for a determination of index weighting. Upon initiation at step  402 , step  404  gets index data from data source  26  as needed. The needed data could be, for example, various indexes of a mutual fund family, or an ETF. Each index can be evaluated independently or collectively. Step  406  makes a time sequence determination, i.e., an internal determination of portfolio reweighting based on computer optimization with respect to time provided by step  408 . Step  412  uses a computer, such as computer  20 , to optimize weight with respect to using relative strength, alpha or a combination thereof to determine relative weights. Any suitable optimization program, such as Trade Station or other optimization program can provide the optimization. At step  410 , index fund management makes a portfolio actual weight determination based on the computer optimization result of step  412 . At step  412 , index fund management decides to accept, reject or change the optimization suggestions provided by step  412 . Step  414  provides a list of the weighting of the index components approved by step  410 . Step  416  provides a list of the weighting of the index components approved by step  410  for an ETF based on the actual weight determination of step  410 . Step  420 , based on the net available dollars from customer buying and selling of fund shares, sorts or ranks the components of a fund index by weight for daily rebalancing according to investor net buy and sell demand for the time period under consideration, e.g., one day. Step  424  sorts or ranks the components of an EFT by weight for daily rebalancing according to investor net buy or sell demand. Process  400  ends at step  426 .  
         [0136]     The present invention having been thus described with particular reference to the preferred forms thereof, it will be obvious that various changes and modifications may be made therein without departing from the spirit and scope of the present invention as defined in the appended claims.
