May 28, 2021.

I. Introduction

On February 11, 2021, The Nasdaq Stock Market LLC (“Exchange” or “Nasdaq”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 19b-4 thereunder,^[2] a proposed rule change to amend Equity 4, Rule (“Rule”) 4754 relating to the Limit Up-Limit Down (“LULD”) closing cross. The proposed rule change was published for comment in the Federal Register on March 3, 2021.^[3] On April 9, 2021, the Exchange filed Amendment No. 1 to the proposed rule change, which amended and superseded the proposed rule change as originally filed.^[4] On April 15, 2021, pursuant to Section 19(b)(2) of the Act,^[5] the Commission designated a longer period within which to approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether to disapprove the proposed rule change.^[6] The Commission has not received any comment letters on the proposed rule change. The Commission is publishing this notice to solicit comments on Amendment No. 1 from interested persons, and is approving the proposed rule change, as modified by Amendment No. 1, on an accelerated basis.

II. Description of the Proposed Rule Change, as Modified by Amendment No. 1

The Nasdaq closing cross is the Exchange's process for determining the price at which orders will be executed at the close and for executing those orders, and the price determined by the Nasdaq closing cross is the Nasdaq official closing price for securities that participate in the cross.^[7] The Nasdaq closing cross begins at 4:00 p.m.,^[8] and the Exchange applies a price range within which the Nasdaq closing cross must occur.^[9] Currently, the Exchange applies a threshold amount that is the greater of $0.50 or 10% of the midpoint of the Nasdaq best bid and offer, and that amount is then added to the Nasdaq best offer and subtracted from the Nasdaq best bid to establish the price range.^[10]

The LULD closing cross is the Exchange's process for executing closing trades in Nasdaq-listed securities when an LULD trading pause pursuant to Rule 4120(a)(12) exists at or after 3:50 p.m. and before 4:00 p.m.^[11] The Exchange proposes to make certain changes to the LULD closing cross in order to further align that process with the regular Nasdaq closing cross process.^[12]

A. LULD Closing Cross Time and Benchmark Prices

Currently, unlike the regular Nasdaq closing cross, the LULD closing cross occurs at 4:00 p.m. unless an order imbalance exists, in which case the Exchange will extend the time of the cross by one minute until the order imbalance no longer exists.^[13] If this condition persists until 5:00 p.m., the Exchange will not conduct an LULD closing cross in the security and will instead use the last sale on the Exchange as the Nasdaq official closing price for that security.^[14] In addition, currently, unlike the regular Nasdaq closing cross, the Exchange does not apply a price range within which the LULD closing cross must occur. The Exchange now proposes to eliminate extensions of the LULD closing cross beyond 4:00 p.m.^[15] and to require that the LULD closing cross occur within certain benchmark prices.

As proposed, for any security that entered a trading pause that was extended prior to 3:50 p.m., the upper (lower) benchmark price would be established by adding (subtracting) a threshold amount to the upper (from the lower) auction collar ^[16] that was last updated with the extension of the trading pause, rounded to the nearest minimum price increment (with midpoint prices being rounded up), and the lower (upper) benchmark price would be the lower (upper) auction collar that was last updated with the upper (lower) auction collar used to calculate the upper (lower) benchmark price.^[17] For any security that entered a trading pause that was not extended prior to 3:50 p.m., the upper (lower) benchmark price would be established by adding (subtracting) a threshold amount to the upper auction collar for a Limit Up triggered pause (from the lower auction collar for a Limit Down triggered pause), rounded to the nearest minimum price increment (with midpoint prices being rounded up), and the lower (upper) benchmark price would be the lower (upper) auction collar disseminated with the upper (lower) auction collar used to calculate the upper (lower) benchmark price.^[18] For any security that entered a trading pause at or after 3:50 p.m., the upper (lower) benchmark price would be established by adding (subtracting) a threshold amount to the upper band for a Limit Up triggered pause (from the lower band for a Limit Down triggered pause), rounded to the nearest minimum price increment (with midpoint prices being rounded up), and the lower (upper) benchmark price would be the lower (upper) band in place at the time the trading pause was triggered.^[19] The benchmark prices would be published via the Nasdaq UTP SIP and Exchange proprietary data feeds.^[20]

The Exchange proposes to initially set the price threshold amounts at the greater of $1.00 or 10% for securities with a reference price greater than $1.00 (or $0.50 for securities with a reference price equal to or less than $1.00).^[21] As proposed, Nasdaq management would be able to set and modify these thresholds from time to time upon prior notice to market participants.^[22]

As proposed, at 4:00 p.m., the Exchange would conduct the LULD closing cross, and if the cross price would fall outside of the benchmark prices, the LULD closing cross would execute all available orders at a price within or equal to the benchmark prices.^[23] Any unexecuted orders intended for the LULD closing cross (i.e., market on close (“MOC”),^[24] limit on close (“LOC”),^[25] and imbalance only (“IO”) orders),^[26] including those that fall outside the benchmark prices, would be cancelled.^[27] All other orders not executed in the LULD closing cross would be processed according to the entering firm's instructions.^[28]

B. LULD Closing Cross Price Determination

Currently, the LULD closing cross price is determined by the same execution algorithm as the regular Nasdaq closing cross.^[29] The Exchange now proposes to modify the methodology for determining the LULD closing cross price.^[30] As proposed, the LULD closing cross would occur at the price within the benchmark prices established pursuant to proposed Rule 4754(b)(6)(E) that maximizes the number of shares of eligible interest,^[31] MOC, LOC, and IO orders in the Nasdaq market center to be executed.^[32] If more than one such price exists, the LULD closing cross would occur at the price within the benchmark prices that minimizes any imbalance.^[33] If more than one such price exists, the LULD closing cross would occur at the entered price within the benchmark prices at which shares will remain unexecuted in the cross.^[34] If no price within the benchmark prices would satisfy these conditions, then: (i) If an imbalance exists, the LULD closing cross would occur at a price equal to the upper (lower) benchmark price for a buy (sell) imbalance; and (ii) if no imbalance exists, the LULD closing cross would occur at a price that minimizes the distance from the last published upper band (lower band) for a Limit Up (Limit Down) trading pause.^[35]

Currently, Rule 4754(b)(6) provides that, in the event of an LULD closing cross, MOC, LOC, and IO orders intended for the closing cross entered into the system and place on the book prior to the trading pause will remain on the book to participate in the LULD closing cross, but these orders may not be modified or cancelled. Rule 4754(b)(6) also provides that, during the pause and prior to 4:00 p.m., new orders (other than MOC or LOC orders) may be entered, modified, and cancelled and may participate in the LULD closing cross. The Exchange now proposes to modify the handling of MOC, LOC, and IO orders such that they could be entered, modified, and cancelled pursuant to Rules 4702(b)(11), 4702(b)(12), and 4702(b)(13), respectively.^[36] Therefore, as proposed, MOC, LOC, and IO orders could be entered, modified, and cancelled during the same time periods for an LULD closing cross as for a regular Nasdaq closing cross. However, unlike the regular Nasdaq closing cross where if the price of an IO order to buy (sell) is higher than (lower than) the highest bid (lowest offer) on the Nasdaq book, the price of the IO order will be modified repeatedly to equal the highest bid (lowest offer) on the Nasdaq book,^[37] for purposes of LULD closing cross price selection, buy (sell) IO orders would be re-priced to one minimum price increment below (above) the LULD band that triggered the trading pause.^[38]

C. Imbalance Information

Currently, Rule 4754(b)(6)(B) provides that, in the event of an LULD closing cross, the Exchange continues disseminating the order imbalance indicator (“NOII”) every second until after hours trading begins. The Exchange proposes to amend this rule to also specify the dissemination of the early order imbalance indicator (“EOII”) before the LULD closing cross.^[39] As with the regular Nasdaq closing cross, EOII would be disseminated every 10 seconds beginning at 3:50 p.m. until the NOII begins to disseminate, and the NOII would be disseminated every second beginning at 3:55 p.m. until market close.^[40]

Currently, Rule 4754(b)(6)(B) also provides that the near price, far price, and reference prices contained in the NOII all represent the price at which the LULD closing cross would execute should the cross conclude at that time. As proposed, the near clearing price ^[41] and reference price contained in the EOII and NOII, as applicable, would represent the price at which the LULD closing cross would execute should the cross conclude at that time (i.e., bounded by the benchmark prices),^[42] and the far clearing price would represent the price at which eligible interest, MOC, LOC, and IO orders would execute (i.e., not bounded by the benchmark prices).^[43]

D. Other Changes

The Exchange proposes to specify in Rule 4754(b)(6) that the LULD closing cross process only applies to Nasdaq-listed securities, rather than all stocks. The Exchange also proposes a conforming change in Rule 4754(b)(6)(B)(i) to clarify that the LULD closing cross applies when a trading pauses exists (rather than is triggered) at or after 3:50 p.m. and before 4:00 p.m. Finally, the Exchange proposes to update obsolete cross references in Rules 4756(c)(3)(B) and 4763(b) to Rule 4751.^[44]

III. Discussion and Commission Findings

After careful review, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange.^[45] In particular, the Commission finds that the proposed rule change, as modified by Amendment No, 1, is consistent with Section 6(b)(5) of the Act,^[46] which requires, among other things, 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 foster cooperation and coordination with persons engaged in facilitating transactions in securities, 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.

The Commission believes that the proposed benchmark prices and other changes to the LULD closing cross would more closely align the LULD closing cross process with the regular Nasdaq closing cross process and would promote a more consistent experience for those that participate in the crosses. The Commission also believes that the differences between the proposed LULD closing cross process and the regular Nasdaq closing cross process are reasonably designed to reflect the differences in market conditions leading up to the crosses.

More specifically, the Commission believes that the proposed benchmark prices for the LULD closing cross would help ensure that the closing price of a security is reasonably related to current market conditions. The Commission also believes that the addition of benchmark prices would further harmonize the LULD closing cross process with the regular Nasdaq closing cross process, while reflecting market conditions for the security leading up to the LULD closing cross. In particular, the Commission believes that the proposed methodology for determining the benchmark prices would reflect that there is no continuous trading in the security and no Nasdaq best bid and offer based on continuous trading in the security during the pause leading up to the cross,^[47] that the cross would occur following a period of increased volatility in the security,^[48] and the direction of trading that triggered the pause in the security and the existence of buy or sell pressure in the security leading up to the cross.^[49]

The Commission also believes that the proposed methodology for determining the LULD closing cross price would reflect the proposed benchmark prices and allow for similar experiences for those that participate in the regular Nasdaq closing cross and the LULD closing cross. In addition, the Commission believes that the proposed methodology, including the proposed definitions of eligible interest and imbalance and the proposed treatment of IO orders, are reasonably designed to reflect market conditions leading up to the LULD closing cross, including that there is no continuous trading in the security and no Nasdaq best bid and offer based on continuous trading in the security leading up to the cross, and the existence of any buy or sell imbalance in the security leading up to the cross.

Further, the Commission believes that the proposal to eliminate extensions of the LULD closing cross past 4:00 p.m. would provide more certainty regarding the timing of the LULD closing cross and align that timing with the regular Nasdaq closing cross. The Commission also believes that the proposed timing for entering, modifying, and cancelling MOC, LOC, and IO orders for the LULD closing cross would allow additional interest to participate in the cross and further align the LULD closing cross process with the regular Nasdaq closing cross process with respect to these orders.

Finally, the Commission believes that the proposal to specify the dissemination of EOII would provide transparency regarding the information that is disseminated in advance of the LULD closing cross.^[50] Similarly, the Commission believes that the proposal to specify that the LULD closing cross only applies to Nasdaq-listed securities and clarify that the LULD closing cross applies when a trading pause exists (rather than is triggered) at or after 3:50 p.m. and before 4:00 p.m. would provide greater transparency regarding the LULD closing cross process. The Commission also believes that updating obsolete cross references in Rules 4756(c)(3)(B) and 4763(b) would provide greater clarity in the Exchange's rules.

V. Accelerated Approval of Proposed Rule Change, as Modified by Amendment No. 1

The Commission finds good cause to approve the proposed rule change, as modified by Amendment No. 1, prior to the thirtieth day after the date of publication of notice of the filing of Amendment No. 1 in the Federal Register. As discussed above, in Amendment No. 1, the Exchange specified the dissemination of certain imbalance information before the LULD closing cross, clarified the process for calculating the LULD closing cross price and the benchmark prices, specified the treatment of IO orders for purposes of LULD closing cross price selection, provided additional explanation to support the proposal, specified the implementation date for the proposal, and made other clarifying, technical, and conforming changes. The Commission believes that the changes made in Amendment No. 1 do not raise any material or novel regulatory issues and they provide further clarity to and consistency within the proposal. Accordingly, the Commission finds good cause, pursuant to Section 19(b)(2) of the Act,^[51] to approve the proposed rule change, as modified by Amendment No. 1, on an accelerated basis.

VI. Conclusion

It is therefore ordered, pursuant to Section 19(b)(2) of the Act,^[52] that the proposed rule change (SR-NASDAQ-2021-009), as modified by Amendment No. 1, be, and hereby is, approved on an accelerated basis.

For the Commission, by the Division of Trading and Markets, pursuant to delegated authority.^[53]

15.  In connection with eliminating extensions of the LULD closing cross, the Exchange proposes to remove Rule 4754(b)(6)(A)(iii), which currently describes extensions of the LULD closing cross, and parts of Rule 4754(b)(6)(C)(iii), which currently describe the handling of certain orders after 4:00 p.m. for purposes of the LULD closing cross.

16.  See Rule 4120(c)(10) (describing the auction collars for reopening following an LULD trading pause).

17.  See proposed Rule 4754(b)(6)(E)(i). The Exchange states that it would use the last widened auction collar in this scenario because a security that entered a trading pause prior to 3:50 p.m. would be subject to the Exchange's reopening process in Rule 4120(c)(10), where the Exchange would halt the security for an initial five-minute period and extend the halt in five-minute increments if the specified reopening criteria are not met, widening the relevant auction collar at the start of each five-minute extension. See Amendment No. 1, supra note 4, at 9 n.18.

18.  See proposed Rule 4754(b)(6)(E)(ii). The Exchange states that this scenario would cover securities that entered a trading pause between 3:45 p.m. and 3:50 p.m., and because the Exchange does not extend the reopening process in Rule 4120(c)(10) or widen auction collars past 3:50 p.m., it would use the initial reopening auction collar. See Amendment No. 1, supra note 4, at 9-10 n.19.

19.  See proposed Rule 4754(b)(6)(E)(iii). The Exchange states that it would use the LULD band that triggered the pause in this scenario because the Exchange does not conduct the LULD reopening process at or after 3:50 p.m. and therefore there are no reopening auction collars in this scenario. See Amendment No. 1, supra note 4, at 10 n.20.

20.  See Amendment No. 1, supra note 4, at 8.

21.  See id. at 8-9.

22.  See proposed Rule 4754(b)(6)(E). These threshold amounts, like the threshold amounts currently used for the regular Nasdaq closing cross, would be published on the Exchange's public website. See Amendment No. 1, supra note 4, at 8.

23.  See Amendment No. 1, supra note 4, at 12.

24.  See Rule 4702(b)(11) (defining a MOC order as an order type entered without a price that may be executed only during the Nasdaq closing cross).

25.  See Rule 4702(b)(12) (defining a LOC order as an order type entered with a price that may be executed only in the Nasdaq closing cross, and only if the price determined by the Nasdaq closing cross is equal to or better than the price at which the LOC order was entered).

26.  See Rule 4702(b)(13) (defining an IO order as an order entered with a price that may be executed only in the Nasdaq closing cross and only against MOC orders or LOC orders).

27.  See Amendment No. 1, supra note 4, at 12.

28.  See id.

29.  See id. at 16.

30.  See proposed Rule 4754(b)(6)(D). See also Rule 4754(b)(2)(A)-(F) (describing the methodology for determining the regular Nasdaq closing cross price).

31.  For purposes of the LULD closing cross, the Exchange proposes to define “eligible interest” to have the same meaning as “close eligible interest” in Rule 4754(a), with the addition of any new orders with an eligible underlying order type and order attribute entered during the trading pause. See proposed Rule 4754(b)(6)(A)(i). See also Rule 4754(a)(1) (defining “close eligible interest” to mean any quotation or any order that may be entered into the system and designated with a time-in-force of SDAY, SGTC, MDAY, MGTC, SHEX, or GTMC).

32.  See proposed Rule 4754(b)(6)(D)(i). The Exchange states that proposed Rule 4754(b)(6)(D)(i) is similar to Rule 4754(b)(2)(A) (i.e., maximizing the number of shares executed in the cross). See Amendment No. 1, supra note 4, at 16.

33.  See proposed Rule 4754(b)(6)(D)(ii). For purposes of the LULD closing cross, the Exchange proposes to define “imbalance” to mean the number of shares of buy or sell MOC or LOC orders or eligible interest that cannot be matched with other MOC, LOC, or IO orders or eligible interest at a particular price at any given time. See proposed Rule 4754(b)(6)(A)(ii). The Exchange states that proposed Rule 4754(b)(6)(D)(ii) is based on the same principle as Rule 4754(b)(2)(B) (i.e., minimizing the number of shares that cannot be matched in the cross). See Amendment No. 1, supra note 4, at 17.

34.  See proposed Rule 4754(b)(6)(D)(iii). The Exchange states that proposed Rule 4754(b)(6)(D)(iii) is similar to Rule 4754(b)(2)(C). See Amendment No. 1, supra note 4, at 18.

35.  See proposed Rule 4754(b)(6)(D)(iv). The Exchange states that Rule 4754(b)(2)(D) uses the midpoint of the Nasdaq best bid and offer as the tiebreaker for the regular Nasdaq closing cross, whereas there would be no continuous market prior to the execution of the LULD closing cross and proposed Rule 4754(b)(6)(D)(iv) would better reflect current market forces and conditions for an LULD closing cross. See Amendment No. 1, supra note 4, at 18-19.

36.  See proposed Rule 4754(b)(6)(F)(ii).

37.  See Rule 4702(b)(13)(A).

38.  See proposed Rule 4754(b)(6)(F)(iii).

39.  See proposed Rule 4754(b)(6)(C).

40.  See id.; Amendment No. 1, supra note 4, at 21-22. See also Rule 4754(b)(1) (describing EOII and NOII dissemination for the regular Nasdaq closing cross).

41.  The Exchange proposes to replace all references to the “near price” and “far price” with the “near clearing price” and “far clearing price” respectively to align with terminology used throughout Rule 4754. See Amendment No. 1, supra note 4, at 22.

42.  See proposed Rule 4754(b)(6)(C); Amendment No. 1, supra note 4, at 22.

43.  See proposed Rule 4754(b)(6)(C); Amendment No. 1, supra note 4, at 22. The far clearing price would be different from the near clearing price and reference price to indicate that not all marketable orders can be filled within the benchmark prices. See Amendment No. 1, supra note 4, at 22.

44.  See Amendment No. 1, supra note 4, at 23.

45.  In approving this proposed rule change, the Commission has considered the proposed rule's impact on efficiency, competition, and capital formation. See 15 U.S.C. 78c(f).

46.  15 U.S.C. 78f(b)(5).

47.  As described above, the benchmark prices for the LULD closing cross would be calculated based on the reopening auction collars or the LULD bands, rather than the midpoint of the Nasdaq best bid and offer as is the case with the regular Nasdaq closing cross.

48.  As described above, the initial threshold amounts for determining the benchmark prices for the LULD closing cross (i.e., the greater of $1.00 or 10% for securities with a reference price greater than $1.00, and $0.50 for securities with a reference price equal to or less than $1.00) may be greater than the current threshold amounts for determining the price range for the regular Nasdaq closing cross (i.e., the greater of $0.50 or 10%). As with the regular Nasdaq closing cross, Nasdaq management would be able to set and modify these threshold amounts from time to time upon prior notice to market participants.

49.  As described above, the threshold amounts for the LULD closing cross would be applied to the most recently expanded reopening auction collar (if the trading pause was extended before 3:50 p.m.) or in the direction of trading that caused the trading pause (if the trading pause was not extended before 3:50 p.m. or if the trading pause occurred at or after 3:50 p.m.), whereas the threshold amounts for the regular Nasdaq closing cross are applied to both the Nasdaq best bid and Nasdaq best offer.

50.  The Commission also believes that the proposed differences between the near clearing price and reference price, and the far clearing price, would reflect the addition of benchmark prices to the LULD closing cross.
