---------------------------------------------------------------------------

II. Description of the Proposal, as Amended

    Currently, position limits for options on ETFs and ETNs, such as 
those subject to this proposal, are determined pursuant to Exchange 
Rule 4.11, and, with certain exceptions, vary according to the number 
of outstanding shares and past six-month trading volume of the 
underlying stocks, ETFs, or ETNs. Options on the securities with the 
largest numbers of outstanding shares and trading volume have an option 
position limit of 250,000 contracts (with adjustments for splits, re-
capitalizations, etc.) on the same side of the market; and stocks, 
ETFs, and ETNs with fewer outstanding shares and lower trading volume 
have position limits of 200,000, 75,000, 50,000, or 25,000 contracts 
(with adjustments for splits, re-capitalizations, etc.) on the same 
side of the market. Options on FXI, EFA, EWZ, TLT, VXX, and EWJ are 
currently subject to the standard position limit of 250,000 contracts 
as set forth in Exchange Rule 4.11.\8\ Interpretation and Policy .07 of 
Exchange Rule 4.11 currently sets forth separate position limits for 
options on certain ETFs, including 500,000 contracts for options on EEM 
and IWM, and 900,000 contracts for options on QQQQ.\9\
---------------------------------------------------------------------------

    \8\ See Notice, supra note 3, at 41457. The Exchange states that 
FXI tracks the performance of the FTSE China 50 Index, which is 
composed of the 50 largest Chinese stocks and EFA tracks the 
performance of MSCI EAFE Index, which has over 900 component 
securities. Id. at 41458. The Exchange also states that the MSCI 
EAFE Index ``is designed to represent the performance of large and 
mid-cap securities across 21 developed markets, including countries 
in Europe, Australasia and the Far East, excluding the U.S. and 
Canada.'' Id. According to the Exchange, EWZ tracks the performance 
of the MSCI Brazil 25/50 Index, which is composed of shares of large 
and mid-size companies in Brazil and TLT tracks the performance of 
ICE U.S. Treasury 20+ Year Bond Index, which is composed of long-
term U.S. Treasury bonds. Id. The Exchange also states that VXX 
tracks the performance of S&P 500 VIX Short-Term Futures Index Total 
Return. Id. According to the Exchange, ``the Index is designed to 
provide access to equity market volatility through CBOE Volatility 
Index futures. The Index offers exposure to a daily rolling long 
position in the first and second month VIX futures contracts and 
reflects market participants' views of the future direction of the 
VIX index at the time of expiration of the VIX futures contracts 
comprising the Index.'' Id. The Exchange also states that EWJ tracks 
the MSCI Japan Index, which tracks the performance of large and mid-
sized companies in Japan. Id.
    \9\ The Exchange states that EEM tracks the performance of the 
MSCI Emerging Markets Index, which is composed of approximately 800 
component securities. According to the Exchange, the MSCI Emerging 
Markets Index ``consists of the following 21 emerging market country 
indices: Brazil, Chile, China, Colombia, Czech Republic, Egypt, 
Hungary, India, Indonesia, Korea, Malaysia, Mexico, Morocco, Peru, 
Philippines, Poland, Russia, South Africa, Taiwan, Thailand, and 
Turkey.'' Id. The Exchange also states that IWM tracks the 
performance of the Russell 2000 Index, which is composed of 2,000 
small-cap domestic stocks, and QQQQ tracks the performance of the 
Nasdaq-100 Index, which is composed of 100 of the largest domestic 
and international nonfinancial companies listed on the Nasdaq Stock 
Market LLC. Id.
---------------------------------------------------------------------------

    The purpose of the proposed rule change, as amended, is to amend 
Interpretation and Policy .07 to Exchange Rule 4.11 to increase the 
position and exercise limits for options on FXI, EFA, EWZ, TLT, VXX, 
and EWJ to from 250,000 contracts to 500,000 contracts.\10\ The 
Exchange further proposes to amend Interpretation and Policy .07 to 
Exchange Rule 4.11 to increase the position limits for options on EEM 
and IWM from 500,000 contracts to 1,000,000 contracts, and to increase 
the position limits for options on QQQQ from 900,000 contracts to 
1,800,000 contracts.\11\ The Exchange states its belief that increasing 
position limits for the options subject to this proposal will lead to a 
more liquid and competitive market environment for these options that 
will benefit customers interested in this product.\12\
---------------------------------------------------------------------------

    \10\ Pursuant to Exchange Rule 4.12, Interpretation and Policy 
.02, which is not being amended by the proposed rule change, the 
exercise limits for FXI, EFA, EWZ, TLT, VXX, and EWJ options would 
be similarly increased.
    \11\ Pursuant to Exchange Rule 4.12, Interpretation and Policy 
.02, which is not being amended by the proposed rule change, the 
exercise limits for EEM, IWM, and QQQQ options would be similarly 
increased. The Exchange also proposes to make non-substantive 
corrections to the names of IWM and EEM in Rule 4.11, Interpretation 
and Policy .07.
    \12\ See Notice, supra note 3, at 41459.
---------------------------------------------------------------------------

    In support of its proposal to increase the position limits for QQQQ 
to 1,800,000 contracts, the Exchange compared the trading 
characteristics of QQQQ to that of the SPDR S&P 500 ETF (``SPY''), 
which currently has no position limits.\13\ The Exchange states that 
the average daily trading volume through August 14, 2017 for QQQQ was 
26.25 million shares compared to 64.63 million shares for SPY.\14\ The 
total shares outstanding for QQQQ were 351.6 million compared to 976.23 
million for SPY.\15\ The fund market cap for QQQQ was $50,359.7 million 
compared to $240,540 million for SPY.\16\
---------------------------------------------------------------------------

    \13\ See id. at 41458. See also Exchange Rule 4.11, 
Interpretation and Policy .07. The Commission notes that the lack of 
position limits for SPY is currently subject to a pilot program. See 
Securities Exchange Act Release Nos. 67937 (September 27, 2012), 77 
FR 60489 (October 3, 2012) (SR-CBOE-2012-091) (eliminating position 
and exercise limits for SPY options on a pilot basis); and 81017 
(June 26, 2017), 82 FR 29960 (June 30, 2017) (SR-CBOE-2017-050) 
(extending the SPY pilot program to July 12, 2018).

    In support of its proposal to increase the position limits for EEM 
and IWM from 500,000 contracts to 1,000,000 contracts, the Exchange 
compared the trading characteristics of EEM and IWM to that of QQQQ, 
which currently has a position limit of 900,000 contracts.\17\ The 
Exchange states that the average daily trading volume through July 31, 
2017 for EEM was 52.12 million shares and IWM was 27.46 million shares 
compared to 26.25 million shares for QQQQ.\18\ The total shares 
outstanding for EEM were 797.4 million and for IWM were 253.1 million 
compared to 351.6 million for QQQQ.\19\ The fund market cap for EEM was 
$34,926.1 million and IWM was $35,809.1 million compared to $50,359.7 
million for QQQQ.\20\

    In support of its proposal to increase the position limits for FXI, 
EFA, EWZ, TLT, VXX, and EWJ from 250,000 contracts to 500,000 
contracts, the Exchange compared the trading characteristics of FXI, 
EFA, EWZ, TLT, VXX, and EWJ to that of EEM and IWM, both of which 
currently have a position limit of 500,000 contracts.\21\ The Exchange 
states that the average daily

[[Page 57503]]

trading volume through July 31, 2017 for FXI was 15.08 million shares, 
EFA was 19.42 million shares, EWZ was 17.08 million shares, TLT was 
8.53 million shares, VXX was 55.04 million shares, and EWJ was 6.06 
million shares compared to 52.12 million shares for EEM and 27.46 
million shares for IWM.\22\ The total shares outstanding for FXI was 
78.6 million, EFA was 1178.4 million, EWZ was 159.4 million, TLT was 60 
million, VXX was 96.7 million, and EWJ was 303.6 million compared to 
797.4 million for EEM and 253.1 million for IWM.\23\ The fund market 
cap for FXI was $3,343.6 million, EFA was $78,870.3 million, EWZ was 
$6,023.4 million, TLT was $7,442.4 million, VXX was $1,085.6 million, 
and EWJ was $16,625.1 million compared to $34,926.1 million for EEM and 
$35,809.1 million for IWM.\24\

---------------------------------------------------------------------------

    The Exchange notes that the options reporting requirements of 
Exchange Rule 4.13 would continue to be applicable to the options 
subject to this proposal.\25\ As set forth in Exchange Rule 4.13(a), 
each Trading Permit Holder (``TPH'') must report to the Exchange 
certain information in relation to any customer who, acting alone, or 
in concert with others, on the previous business day maintained 
aggregate long or short positions on the same side of the market of 200 
or more contracts in any single class of option contracts dealt in on 
the Exchange.\26\ Further, Exchange Rule 4.13(b) requires each TPH 
(other than an Exchange market-maker or Designated Primary Market-
Maker) \27\ that maintains a position in excess of 10,000 non-FLEX 
equity option contracts on the same side of the market, on behalf of 
its own account or for the account of a customer, to report to the 
Exchange information as to whether such positions are hedged, and 
provide documentation as to how such contracts are hedged.\28\
---------------------------------------------------------------------------

    \25\ See id.
    \26\ The report must include, for each such class of options, 
the number of option contracts comprising each such position and, in 
the case of short positions, whether covered or uncovered. See 
Exchange Rule 4.13(a).
    \27\ According to the Exchange, market-makers (including 
Designated Primary Market-Makers) are exempt from the referenced 
reporting requirement because market-maker information can be 
accessed through the Exchange's market surveillance systems. See 
Notice, supra note 3, at 41459.
    \28\ According to the Exchange, this information would include, 
but would not be limited to, the option position, whether such 
position is hedged and, if so, a description of the hedge, and the 
collateral used to carry the position, if applicable. See id.
---------------------------------------------------------------------------

    The Exchange believes that the existing surveillance procedures and 
reporting requirements at the Exchange, other options exchanges, and at 
the several clearing firms are capable of properly identifying unusual 
and/or illegal trading activity.\29\ According to the Exchange, its 
surveillance procedures utilize daily monitoring of market movements 
via automated surveillance techniques to identify unusual activity in 
both options and underlying stocks.\30\ In addition, the Exchange 
states that its surveillance procedures have been effective for the 
surveillance of trading in the options subject to this proposal, and 
will continue to be employed.\31\
---------------------------------------------------------------------------

    \29\ See id.
    \30\ See id.
    \31\ See id. at 41459 n.23. The Exchange represents that more 
than 50% of the weight of the securities held by the options subject 
to this proposal are also subject to a comprehensive surveillance 
agreement (``CSA''). See id. at 41458. Additionally, the Exchange 
states that the component securities of the MSCI Emerging Markets 
Index on which EEM is based for which the primary market is in any 
one country that is not subject to a CSA do not represent 20% or 
more of the weight of the MSCI Emerging Markets Index. See id. 
Further, the Exchange states that the component securities of the 
MSCI Emerging Markets Index on which EEM is based for which the 
primary market is in any two countries that are not subject to CSAs 
do not represent 33% or more of the weight of the MSCI Emerging 
Markets Index. See id.
---------------------------------------------------------------------------

    The Exchange further states its belief that the current financial 
requirements imposed by the Exchange and by the Commission adequately 
address concerns that a TPH or its customer may try to maintain an 
inordinately large unhedged position in the options subject to this 
proposal.\32\ Current margin and risk-based haircut methodologies, the 
Exchange states, serve to limit the size of positions maintained by any 
one account by increasing the margin and/or capital that a TPH must 
maintain for a large position held by itself or by its customer.\33\ In 
addition, the Exchange notes that the Commission's net capital rule, 
Rule 15c3-1 under the Act,\34\ imposes a capital charge on TPHs to the 
extent of any margin deficiency resulting from the higher margin 
requirement.\35\

---------------------------------------------------------------------------

Amendment No.1

    As noted above, on November 22, 2017, the Exchange filed Amendment 
No. 1 to the proposed rule change to provide additional justification 
and support for the proposal. In Amendment No. 1, the Exchange states 
that it submitted the proposal at the request of market participants 
whose on-exchange activity has been ``hindered by existing position 
limits, causing them to be unable to provide additional liquidity not 
just on the Exchange, but also on other options exchanges on which they 
participate.'' \36\ In further support of its proposed increases in 
position limits, in Amendment No. 1, the Exchange describes at length: 
(i) The creation and redemption process for ETFs (and a similar process 
for the ETN to which the proposal relates \37\); (ii) the arbitrage 
activity that ensues when such instruments are overpriced or are 
trading at a discount to the securities on which they are based and 
helps to keep the instrument's price in line with the value of its 
underlying portfolio; and (iii) how these processes serve to mitigate 
the potential price impact of the ETF or ETN shares that might 
otherwise result from increased position limits.\38\
---------------------------------------------------------------------------

    \36\ See Amendment No. 1 at 4-5. The Exchange reiterates its 
understanding that certain market participants are opting to execute 
trades involving large numbers of options contracts in the symbols 
subject to the proposal in the over-the-counter market, and argues 
that these large trades do not contribute to the price discovery 
process performed on a lit market. See id. at 5.
    \37\ With regard to the ETN option included in the proposal--
VXX--the Exchange acknowledged that there is no direct analogue to 
ETF ``creation,'' but observed that the ETN issuer may sell 
additional VXX shares from its inventory. Regardless of whether VXX 
shares are redeemed or new VXX shares are issued, the Exchange 
stated, an issuer may transact in VIX futures in order to hedge its 
exposure, resulting in an arbitrage process similar to the one 
described for ETFs described above, thereby helping to keep an ETN's 
price in line with the value of its underlying index. See Amendment 
No. 1 at 7-8.
    \38\ See id. at 6-7.
---------------------------------------------------------------------------

    In addition, in Amendment No. 1, the Exchange notes that some of 
the ETFs and the ETN to which the proposal relates are based on broad-
based indices that underlie cash-settled options that are economically 
equivalent to the relevant ETF or similar to the relevant ETN, but 
where the option on the index is either subject to no position limit or 
is subject to a position limit reflecting a notional value that is 
larger than the position limit for the option on the ETF absent the 
proposed increase.\39\ For the other ETFs in the proposal where this 
does not apply, the Exchange argues that, based on the liquidity, 
breadth, and depth of the underlying market, the index referenced by 
the ETF would be considered a broad-based index under the Exchange's 
rules.\40\ According to the Exchange, if certain position limits are 
appropriate for the options overlying the

[[Page 57504]]

same index or is an analogue to the basket of securities that the ETF 
tracks, then those same economically equivalent position limits should 
be appropriate for the option overlying the ETF.\41\ The Exchange 
believes that the new position limits it is proposing meet this 
criterion.\42\ The Exchange also cites data in support of its argument 
that the market capitalization of the underlying index or reference 
asset of each of the ETFs and the ETN is large enough to absorb any 
price movements that may be caused by an oversized trade.\43\
---------------------------------------------------------------------------

    \39\ See id. at 8, and the Exchange's discussion of QQQQ, IWM, 
VXX, and EEM, and EFA, id. at 8-11.

TLT, and EWJ, id. at 12-14.
    \41\ See id. at 8.
    \42\ See id. at 8-14. For each of the ETFs and the ETN subject 
to the proposal, the Exchange cites specific data to illustrate its 
argument.

III. Proceedings To Determine Whether To Approve or Disapprove SR-CBOE-
2017-057, as Amended, and Grounds for Disapproval Under Consideration

    The Commission is instituting proceedings pursuant to Section 
19(b)(2)(B) of the Act \44\ to determine whether the proposed rule 
change, as amended, should be approved or disapproved. Institution of 
proceedings is appropriate at this time in view of the legal and policy 
issues raised by the proposal, as discussed below. Institution of 
proceedings does not indicate that the Commission has reached any 
conclusions with respect to any of the issues involved. Rather, as 
described below, the Commission seeks and encourages interested persons 
to provide comment on the proposed rule change, as amended.
---------------------------------------------------------------------------

    \44\ 15 U.S.C. 78s(b)(2)(B).
---------------------------------------------------------------------------

    Pursuant to Section 19(b)(2)(B) of the Act,\45\ the Commission is 
providing notice of the grounds for disapproval under consideration. 
The Commission notes that position and exercise limits serve as a 
regulatory tool designed to address manipulative schemes and adverse 
market impact surrounding the use of options.\46\ As discussed above, 
the Exchange has proposed to increase the position and exercise limits 
for options on FXI, EFA, EWZ, TLT, VXX, and EWJ from 250,000 contracts 
to 500,000 contracts, for options on EEM and IWM from 500,000 contracts 
to 1,000,000 contracts, and for options on QQQQ from 900,000 contracts 
to 1,800,000 contracts. The proposed increase in position and exercise 
limits for each marks a substantial increase from current levels, for 
which the Exchange recently has provided additional justification and 
analysis.\47\
---------------------------------------------------------------------------

    \45\ Id.
    \46\ See, e.g., Securities Exchange Act Release No. 68086 
(October 23, 2012), 77 FR 65600 (October 29, 2012) (SR-CBOE-2012-
066).
    \47\ The Commission notes that the Exchange filed Amendment No. 
1 to provide additional justification and analysis in support of the 
proposed position and exercise limits on November 22, 2017. See 
supra note 6.
---------------------------------------------------------------------------

    The Commission is instituting proceedings to allow for additional 
analysis of, and input from commenters with respect to, the consistency 
of the proposed rule change, as amended, with Section 6(b)(5) of the 
Act,\48\ which requires that the rules of a national securities 
exchange be designed to prevent fraudulent and manipulative acts and 
practices, to promote just and equitable principles of trade, to remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system and, in general, to protect investors and the 
public interest, and not be designed to permit unfair discrimination 
between customers, issuers, brokers, or dealers.

IV. Procedure: Request for Written Comments

    The Commission requests that interested persons provide written 
submissions of their data, views, and arguments with respect to the 
issues identified above, as well as any other concerns they may have 
with the proposal. In particular, the Commission invites the written 
views of interested persons concerning whether the proposed rule 
change, as amended, is consistent with Section 6(b)(5), or any other 
provision of the Act, or the rules and regulations thereunder. Although 
there do not appear to be any issues relevant to approval or 
disapproval which would be facilitated by an oral presentation of data, 
views, and arguments, the Commission will consider, pursuant to Rule 
19b-4 under the Act,\49\ any request for an opportunity to make an oral 
presentation.\50\
---------------------------------------------------------------------------

    \49\ 17 CFR 240.19b-4.
    \50\ Section 19(b)(2) of the Act, as amended by the Securities 
Acts Amendments of 1975, Public Law 94-29 (June 4, 1975), grants to 
the Commission flexibility to determine what type of proceeding--
either oral or notice and opportunity for written comments--is 
appropriate for consideration of a particular proposal by a self-
regulatory organization. See Securities Acts Amendments of 1975, 
Senate Comm. on Banking, Housing & Urban Affairs, S. Rep. No. 75, 
94th Cong., 1st Sess. 30 (1975).
---------------------------------------------------------------------------

    The Commission asks that commenters address the sufficiency and 
merit of the Exchange's statements in support of the proposal, as 
amended, in addition to any other comments they may wish to submit 
about the proposed rule change. In particular, the Commission seeks 
comment on whether the position and exercise limit for each option as 
proposed could impact markets adversely.
    Interested persons are invited to submit written data, views, and 
arguments regarding whether the proposed rule change, as amended, 
should be approved or disapproved by December 26, 2017. Any person who 
wishes to file a rebuttal to any other person's submission must file 
that rebuttal by January 9, 2018. Comments may be submitted by any of 
the following methods:
