May 20, 2021.

Pursuant to Section 19(b)(1) ^[1] of the Securities Exchange Act of 1934 (“Act”) ^[2] and Rule 19b-4 thereunder,^[3] notice is hereby given that on May 13, 2021, NYSE Arca, Inc. (“NYSE Arca” or the “Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II below, which Items have been prepared by the self-regulatory organization. The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

The Exchange proposes to list and trade the shares of the following under NYSE Arca Rule 8.200-E, Commentary .02 (“Trust Issued Receipts”): ConvexityShares Daily 1.5x SPIKES Futures ETF. The proposed change is available on the Exchange's website at www.nyse.com,, at the principal office of the Exchange, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the self-regulatory organization included statements concerning the purpose of, and basis for, the proposed rule change and discussed any comments it received on the proposed rule change. The text of those statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant parts of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and the Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to list and trade shares (“Shares”) of the following under NYSE Arca Rule 8.200-E, Commentary .02, which governs the listing and trading of Trust Issued Receipts: ConvexityShares Daily 1.5x SPIKES Futures ETF (the “Fund”).^[4]

The Fund is a series of the ConvexityShares Trust (the “Trust”), a Delaware statutory trust.^[5] The Fund is managed and controlled by its sponsor and investment manager, ConvexityShares, LLC (the “Sponsor”). The Fund is a commodity pool and the Sponsor is a commodity pool operator subject to regulation by the Commodity Futures Trading Commission (“CFTC”) and the National Futures Association under the Commodity Exchange Act, as amended. U.S. Bank, a national banking association, will provide custody and fund accounting to the Trust and the Fund. Its affiliate, U.S. Bancorp Fund Services, will be the transfer agent (“Transfer Agent”) for Fund Shares and administrator for the Fund. Foreside will serve as the distributor for the Fund (“Distributor”).

According to the Registration Statement, the Fund is benchmarked to the T3 SPIKE Front 2 Futures Index (the “Index”), an investable index of SPIKES futures contracts. The Fund will seek to offer exposure to forward equity market volatility by obtaining exposure to the components of the Index. The Index, as described further below, is intended to reflect the returns that are potentially available through an unleveraged investment in the SPIKES futures contracts comprising the Index.^[6] The Index consists of short-term SPIKES futures contracts and measures the daily performance of a theoretical portfolio of first- and second-month futures contracts on the SPIKES Volatility Index (“SPIKES Index”).^[7] The SPIKES Index is a non-investable index that measures the implied volatility of the SPDR S&P 500 ETF ^[8] Trust (“SPY”).^[9] The Fund is not benchmarked to the SPIKES Index.

The Index is owned and maintained by T3 Index and is calculated and published by Solactive AG (“Solactive”). Solactive is not affiliated with T3 Index. The Index value calculated at the end of each business day will be available at www.convexityshares.com. The Fund's website will also provide information regarding the SPIKES futures contracts constituting the Index and the Index methodology. Futures contracts on the SPIKES Index, which futures comprise the Index, are traded on the Minneapolis Grain Exchange, LLC (“MGEX”) via the CME Globex® platform.

According to the Registration Statement, the Fund will seek daily investment results, before fees and expenses, that correspond to one-and-a-half times (1.5x) the performance of the Index for a single day. A “single day” is measured from the time the Fund calculates its net asset value (“NAV”) to the time of the Fund's next NAV calculation. The NAV calculation time for the Fund is typically is 4:00 p.m. (Eastern Time (“E.T.”)). The NAV will be calculated by taking the current market value of the Fund's total assets (after the close of the NYSE Arca Core Trading Session (normally, 4:00 p.m., E.T.)), subtracting any liabilities, and dividing that total by the total number of outstanding Shares.

Description of the Index

According to the Registration Statement, the Index employs rules for selecting the SPIKES futures contracts comprising the Index and a formula to calculate a level for the Index from the prices of these SPIKES futures contracts. Currently, the SPIKES futures contracts comprising the Index represent the prices of two near-term SPIKES futures contracts, replicating a position that rolls the nearest month SPIKES futures contracts to the next month SPIKES futures contracts at or close to the daily settlement price via a Trade-At-Settlement ^[10] program towards the end of each business day in equal fractional amounts. This results in a constant weighted average maturity of one month. The rules applicable to the Index are subject to change by T3 Index.

The level of the Index is published by one or more major market data vendors in real time at least once every 15 seconds and at the close of trading in the Exchange's Core Trading Session (normally 4:00 p.m., E.T.) on each business day.

The Index is comprised solely of SPIKES futures contracts. SPIKES futures contracts were launched for trading by MGEX, via the CME Globex® platform, on December 14, 2020. According to the Registration Statement, SPIKES futures contracts allow investors to invest based on their view of the forward implied market volatility of SPY. Investors that believe the forward implied market volatility of SPY will increase may buy SPIKES futures contracts. Conversely, investors that believe that the forward implied market volatility of SPY will decline may sell SPIKES futures contracts. While the SPIKES Index represents a measure of the expected 30-day volatility of SPY, the prices of SPIKES futures contracts are based on the current expectation of the expected 30-day volatility of SPY on the expiration date of the futures contract.

SPIKES Index

According to the Registration Statement, the SPIKES Index is an index designed to measure the implied volatility of SPY over 30 days in the future. The SPIKES Index is calculated based on the prices of certain put and call options on SPY. The SPIKES Index is reflective of the premium paid by investors for certain options linked to the level of the S&P 500. The SPIKES Index is a theoretical calculation and cannot be traded on a spot basis. The SPIKES Index is reported by Bloomberg Finance L.P. and Reuters under the ticker symbol “SPIKE.” The SPIKES Index is calculated and disseminated every 100 milliseconds.

Investment Objectives and Strategies

According to the Registration Statement, the Fund will seek daily investment results, before fees and expenses, that correspond to one-and-a-half times (1.5x) the performance of the Index for a single day. The Fund is benchmarked to the Index, which is comprised of SPIKES futures contracts, and will seek to offer exposure to market volatility through publicly traded futures markets.

Under normal market conditions,^[11] the Fund will invest primarily in SPIKES futures contracts to gain the appropriate exposure to the Index. Under certain circumstances, the Fund may also invest in futures contracts and swap contracts (“VIX Related Positions”) on the Cboe Volatility Index (“VIX”),^[12] an index that tracks volatility and would be expected to perform in a substantially similar manner as the SPIKES Index.

In seeking to achieve the Fund's investment objective, the Sponsor will use a mathematical approach to investing. Using this approach, the Sponsor determines the type, quantity and mix of investments that the Sponsor believes, in combination, should produce daily returns consistent with the Fund's objective.

The Fund seeks to achieve its investment objective through the appropriate amount of exposure to the SPIKES futures contracts included in the Index. The Fund will not directly invest in the SPIKES Index. In addition, under specified circumstances described below, the Fund may invest in VIX Related Positions.

In the event accountability rules, price limits, position limits, margin limits or other exposure limits are reached with respect to SPIKES futures contracts, the Sponsor may cause the Fund to invest in VIX Related Positions. According to the Registration Statement, the Sponsor expects the Fund's positions in VIX Related Positions to consist primarily of VIX futures contracts.^[13] In the event accountability rules, price limits, position limits, margin limits or other exposure limits are reached with respect to VIX futures contracts, or if the market for a specific VIX futures contract experiences emergencies or disruptions or in situations where the Sponsor deems it impractical or inadvisable to buy or sell VIX futures contracts, the Fund would hold VIX swap agreements.

The Fund will also hold cash or cash equivalents such as U.S. Treasury securities or other high credit quality, short-term fixed-income or similar securities (such as shares of money market funds) as collateral for investments and pending investments.

Creation and Redemption of Shares

According to the Registration Statement, the Fund will create and redeem Shares from time to time in one or more “Creation Units” or “Redemption Units” (together, “Units”). A Unit consists of 25,000 Shares. The size of a Unit is subject to change. The creation and redemption of Units are made in exchange for delivery to the Fund or the distribution by the Fund of the amount of cash represented by the Units being created or redeemed, the amount of which is based on the combined NAV of the number of Shares included in the Units being created or redeemed determined as of 4:00 p.m. E.T. on the day the order to create or redeem Units is properly received. If permitted by the Sponsor in its sole discretion with respect to the Fund, an “Authorized Participant” may also agree to enter into or arrange for an exchange of a futures contract for related position (“EFCRP”) or block trade with the Fund whereby the Authorized Participant would also transfer to the Fund a number and type of exchange-traded futures contracts at or near the closing settlement price for such contracts on the purchase order date. Similarly, the Sponsor in its sole discretion may agree with an Authorized Participant to use an EFCRP to effect an order to redeem Units.^[14] All APs would be able to use an EFCRP to effect orders to create or redeem Units.

Authorized Participants are the only persons that may place orders to create and redeem Units. Authorized Participants must be (1) registered broker-dealers or other securities market participants, such as banks and other financial institutions, that are not required to register as broker-dealers to engage in securities transactions, and (2) Depository Trust Company participants.

Creation Procedures

According to the Registration Statement, on any business day, an Authorized Participant may place an order to create one or more Units.^[15] Purchase orders must be placed by 2:00 p.m. E.T. or the close of the Core Trading Session on the NYSE Arca, whichever is earlier. Purchase orders are irrevocable.

The total payment required to create each Creation Unit is the NAV of 25,000 Shares on the purchase order date.

Redemption Procedures

According to the Registration Statement, the procedures by which an Authorized Participant can redeem one or more Units mirror the procedures for the creation of Units. On any business day, an Authorized Participant may place an order with the Transfer Agent, and accepted by the Distributor, to redeem one or more Units. Redemption orders must be placed by 2:00 p.m. E.T. or the close of the Core Trading Session on the NYSE Arca, whichever is earlier. Redemption orders are irrevocable.

Upon request of an Authorized Participant made at the time of a redemption order, the Sponsor at its sole discretion may determine, in addition to delivering redemption proceeds, to transfer futures contracts to the Authorized Participant pursuant to an EFCRP or to a block trade sale of futures contracts to the Authorized Participant.

Determination of Redemption Proceeds

The redemption proceeds from the Fund consist of the cash redemption amount and, if permitted by the Sponsor in its sole discretion with respect to the Fund, an EFCRP or block trade with the Fund as described above. The redemption proceeds from the Fund consist of a cash redemption amount equal to the NAV of the number of Units requested in the Authorized Participant's redemption order on the redemption order date, less transaction fees and any amounts attributable to any applicable EFCRP or block trade.

Indicative Fund Value

In order to provide updated information relating to the Fund for use by investors and market professionals, an updated “Indicative Fund Value” (“IFV”) will be calculated. The IFV will be calculated by using the prior day's closing NAV per Share of the Fund as a base and will be updating throughout the Core Trading Session of 9:30 a.m. E.T. to 4:00 p.m. E.T. to reflect changes in the approximate aggregate per Share value of the investments held by the Fund based on the most recently available prices for the Fund's investments. The IFV will be disseminated on a per Share basis every 15 seconds during the Exchange's Core Trading Session and be widely disseminated by one or more major market data vendors during the NYSE Arca Core Trading Session. The IFV will be readily available from the Fund's website, automated quotation systems, published or other public sources, or major market data vendors' website or on-line information services.

Availability of Information

The NAV for the Fund's Shares will be disseminated daily to all market participants at the same time, after 4 p.m. each day. In addition, the Fund's website, www.convexityshares.com,, will display the end of day closing NAV. The daily holdings of the Fund will be available on the Fund's website before 9:30 a.m. E.T. each day. The website disclosure of portfolio holdings will be made daily and will include, as applicable, (i) the composite value of the total portfolio, (ii) the quantity and type of each holding (including the ticker symbol, maturity date or other identifier, if any) and other descriptive information including, in the case of a swap, the type of swap, its notional value and the underlying instrument, index or asset on which the swap is based, (iii) the market value of each investment held by the Fund, (iv) the type (including maturity, ticker symbol, or other identifier) and value of each Treasury security and cash equivalent, and (v) the amount of cash held in the Fund's portfolio. The Fund's website will be publicly accessible at no charge.

The Fund's website will include a form of the prospectus that may be downloaded. The Fund's website will include additional quantitative information updated on a daily basis, including, trading volume, the prior business day's NAV, market closing price or mid-point of the bid/ask spread at the time of calculation of such NAV (the “Bid/Ask Price”),^[16] and a calculation of the premium and discount of the market closing price or Bid/Ask Price against the NAV. The website and information will be publicly available at no charge.

This website disclosure of the Fund's daily holdings will occur at approximately the same time as the disclosure by the Trust of the daily holdings to Authorized Participants so that all market participants are provided daily holdings information at approximately the same time. Therefore, the same holdings information will be provided on the public website as well as in electronic files provided to Authorized Participants. Accordingly, each investor will have access to the current daily holdings of the Fund through the Fund's website.

Complete real-time data for SPIKES futures contracts is available by subscription through on-line information services. MGEX also provides delayed futures information on current and past trading sessions and market news free of charge on its website. The level of the Index will be published at least every 15 seconds both in real time from 9:30 a.m. to 4 p.m. E.T. and at the close of trading on each business day by Bloomberg and Reuters. The level of the SPIKES Index and the VIX is available from Bloomberg and Reuters. Price information regarding cleared VIX swap contracts is available from major market data vendors. Price information regarding VIX futures is available from the Cboe Futures Exchange and from major market data vendors. Price information for cash equivalents is available from major market data vendors. Price information for non-exchange-traded VIX swap contracts may be obtained from brokers and dealers who make markets in such instruments. Information regarding the previous day's closing price and trading volume information for the Shares will be published daily in the financial section of newspapers. Quotation and last-sale information regarding the Shares will be disseminated through the facilities of the Consolidated Tape Association (“CTA”).

Trading Halts

With respect to trading halts, the Exchange may consider all relevant factors in exercising its discretion to halt or suspend trading in the Shares of the Fund.^[17] Trading in Shares of the Fund will be halted if the circuit breaker parameters in NYSE Arca Rule 7.12-E have been reached. Trading also may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable. The Exchange may halt trading during the day in which an interruption to the dissemination of the IFV or the value of the Index occurs. If the interruption to the dissemination of the IFV or the value of the Index persists past the trading day in which it occurred, the Exchange will halt trading no later than the beginning of the trading day following the interruption. In addition, if the Exchange becomes aware that the NAV with respect to the Shares or disclosure of the Fund's daily holdings is not disseminated to all market participants at the same time, it will halt trading in the Shares until such time as the NAV and the Fund's daily holdings is available to all market participants.

Trading Rules

The Exchange deems the Shares to be equity securities, thus rendering trading in the Shares subject to the Exchange's existing rules governing the trading of equity securities. Shares will trade on the NYSE Arca Marketplace from 4 a.m. to 8 p.m. E.T. in accordance with NYSE Arca Rule 7.34-E (Early, Core, and Late Trading Sessions). The Exchange has appropriate rules to facilitate transactions in the Shares during all trading sessions. As provided in NYSE Arca Rule 7.6-E, the minimum price variation (“MPV”) for quoting and entry of orders in equity securities traded on the NYSE Arca Marketplace is $0.01, with the exception of securities that are priced less than $1.00 for which the MPV for order entry is $0.0001.

The Shares will conform to the initial and continued listing criteria under NYSE Arca Rule 8.200-E. The trading of the Shares will be subject to NYSE Arca Rule 8.200-E, Commentary .02(e), which sets forth certain restrictions on Equity Trading Permit (“ETP”) Holders acting as registered Market Makers in Trust Issued Receipts to facilitate surveillance. A minimum of 100,000 Shares of each Fund will be outstanding at the commencement of trading on the Exchange. With respect to the application of Rule 10A-3 ^[18] under the Act, the Fund will rely on the exception contained in Rule 10A-3(c)(7).^[19] The Exchange will obtain a representation from the issuer of the Shares of the Fund that the NAV per Share of the Fund will be calculated daily and will be made available to all market participants at the same time.

Surveillance

The Exchange represents that trading in the Shares will be subject to the existing trading surveillances administered by the Exchange, as well as cross-market surveillances administered by the Financial Industry Regulatory Authority (“FINRA”) on behalf of the Exchange, which are designed to detect violations of Exchange rules and applicable federal securities laws.^[20] The Exchange represents that these procedures are adequate to properly monitor Exchange trading of the Shares of the Fund in all trading sessions and to deter and detect violations of Exchange rules and federal securities laws applicable to trading on the Exchange.

The surveillances referred to above generally focus on detecting securities trading outside their normal patterns, which could be indicative of manipulative or other violative activity. When such situations are detected, surveillance analysis follows and investigations are opened, where appropriate, to review the behavior of all relevant parties for all relevant trading violations.

The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares, SPIKES futures, VIX futures and other underlying exchange-listed instruments with other markets and other entities that are members of the ISG, and the Exchange or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading in the Shares, SPIKES futures, VIX futures and other underlying exchange-listed instruments from such markets and other entities. In addition, the Exchange may obtain information regarding trading in the Shares, SPIKES futures, VIX futures and other underlying exchange-listed instruments from markets and other entities that are members of ISG or with which the Exchange has in place a comprehensive surveillance sharing agreement (“CSSA”).^[21] The Exchange has in place a CSSA with MGEX regarding trading in all futures contracts on MGEX.

All of the net assets of the Fund invested in futures contracts shall consist of futures contracts whose principal market is a member of the ISG or is a market with which the Exchange has a CSSA.

In addition, the Exchange also has a general policy prohibiting the distribution of material, non-public information by its employees.

All statements and representations made in this filing regarding (a) the description of the Index, portfolio holdings and reference assets, (b) limitations on Index or portfolio holdings or reference assets, or (c) applicability of Exchange listing rules specified in this filing shall constitute continued listing requirements for listing the Shares on the Exchange.

The issuer has represented to the Exchange that it will advise the Exchange of any failure by the Fund to comply with the continued listing requirements, and, pursuant to its obligations under Section 19(g)(1) of the Act, the Exchange will monitor for compliance with the continued listing requirements. If the Fund is not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under NYSE Arca Rule 5.5-E(m).

Information Bulletin

Prior to the commencement of trading, the Exchange will inform its ETP Holders in an Information Bulletin of the special characteristics and risks associated with trading the Shares. Specifically, the Information Bulletin will discuss the following: (1) The risks involved in trading the Shares during the Opening and Late Trading Sessions when an updated IFV will not be calculated or publicly disseminated; (2) the procedures for purchases and redemptions of Shares in Creation Units and Redemption Units (and that Shares are not individually redeemable); (3) NYSE Arca Rule 9.2-E(a), which imposes a duty of due diligence on its ETP Holders to learn the essential facts relating to every customer prior to trading the Shares; (4) how information regarding the IFV is disseminated; (5) how information regarding portfolio holdings is disseminated; (6) the requirement that ETP Holders deliver a prospectus to investors purchasing newly issued Shares prior to or concurrently with the confirmation of a transaction; and (7) trading information.

In addition, the Information Bulletin will advise ETP Holders, prior to the commencement of trading, of the prospectus delivery requirements applicable to the Fund. The Exchange notes that investors purchasing Shares directly from the Fund will receive a prospectus. ETP Holders purchasing Shares from the Fund for resale to investors will deliver a prospectus to such investors. The Information Bulletin will also discuss any exemptive, no-action, and interpretive relief granted by the Commission from any rules under the Act. In addition, the Information Bulletin will reference that the Fund is subject to various fees and expenses described in the Registration Statement.

The Information Bulletin will also disclose the trading hours of the Shares and that the NAV for the Shares will be calculated after 4:00 p.m. E.T. each trading day. The Information Bulletin will disclose that information about the Shares will be publicly available on the Fund's website.

Further, the Exchange states that FINRA has implemented increased sales practice and customer margin requirements for FINRA members applicable to inverse, leveraged and inverse leveraged securities (which include the ConvexityShares Daily 1.5x SPIKES Futures ETF) and options on such securities, as described in FINRA Regulatory Notices 09-31 (June 2009), 09-53 (August 2009), and 09-65 (November 2009). The Fund does not seek to achieve its primary investment objective over a period of time greater than a single day. ETP Holders that carry customer accounts will be required to follow the FINRA guidance set forth in these notices.

2. Statutory Basis

The basis under the Act for this proposed rule change is the requirement under Section 6(b)(5) ^[22] that an exchange have rules that are 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, in general, to protect investors and the public interest.

The Exchange believes that the proposed rule change is designed to prevent fraudulent and manipulative acts and practices in that the Shares will be listed and traded on the Exchange pursuant to the initial and continued listing criteria in NYSE Arca Rule 8.200-E.^[23] The Exchange has in place surveillance procedures that are adequate to properly monitor trading in the Shares of the Fund in all trading sessions and to deter and detect violations of Exchange rules and applicable federal securities laws.

The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares, SPIKES futures, VIX futures and other underlying exchange-listed instruments with other markets and other entities that are members of the ISG, and the Exchange or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading in the Shares, SPIKES futures, VIX futures and other underlying exchange-listed instruments from such markets and other entities. In addition, the Exchange may obtain information regarding trading in the Shares, SPIKES futures, VIX futures and other underlying exchange-listed instruments from markets and other entities that are members of ISG or with which the Exchange has in place a CSSA. The Exchange has in place a CSSA with MGEX regarding trading in all futures contracts on MGEX.

All of the net assets of the Fund invested in futures contracts shall consist of futures contracts whose principal market is a member of the ISG or is a market with which the Exchange has a CSSA.

The NAV for the Fund's Shares will be disseminated daily to all market participants at the same time, after 4 p.m. E.T. each day. Complete real-time data for SPIKES futures contracts is available by subscription through on-line information services. MGEX also provides delayed futures information on current and past trading sessions and market news free of charge on its website. The level of the Index will be published at least every 15 seconds both in real time from 9:30 a.m. to 4 p.m. E.T. and at the close of trading on each business day by Bloomberg and Reuters. The level of the SPIKES Index and the VIX is available from Bloomberg and Reuters. Price information regarding cleared VIX swap contracts is available from major market data vendors. Price information regarding VIX futures is available from the Cboe Futures Exchange and from major market data vendors. Price information for cash equivalents is available from major market data vendors. Price information for non-exchange-traded VIX swap contracts may be obtained from brokers and dealers who make markets in such instruments. Information regarding the previous day's closing price and trading volume information for the Shares will be published daily in the financial section of newspapers. Quotation and last-sale information regarding the Shares will be disseminated through the facilities of the CTA. The IFV will be available through on-line information services.

Moreover, prior to the commencement of trading, the Exchange will inform its Equity Trading Permit Holders in an Information Bulletin of the special characteristics and risks associated with trading the Shares. Trading in Shares of the Fund will be halted if the circuit breaker parameters in NYSE Arca Rule 7.12-E have been reached or because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable.

The proposed rule change is designed to perfect the mechanism of a free and open market and, in general, to protect investors and the public interest in that it will facilitate the listing and trading of an additional type of Trust Issued Receipts based on prices related to market volatility that will enhance competition among market participants, to the benefit of investors and the marketplace. As noted above, the Exchange has in place surveillance procedures that are adequate to properly monitor trading in the Shares in all trading sessions and to deter and detect violations of Exchange rules and applicable federal securities laws.

B. Self-Regulatory Organization's Statement on Burden on Competition

The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purpose of the Act. The Exchange notes that the proposed rule change will facilitate the listing and trading of an additional type of Trust Issued Receipts based on prices related to market volatility and that will enhance competition among market participants, to the benefit of investors and the marketplace.

The Jumpstart Our Business Startups Act, enacted on April 5, 2012, added Section 6(e) to the 1933 Act. Section 6(e) of the 1933 Act provides that an “emerging growth company” may confidentially submit to the Commission a draft registration statement for confidential, non-public review by the Commission staff prior to public filing, provided that the initial confidential submission and all amendments thereto shall be publicly filed not later than 21 days before the date on which the issuer conducts a road show, as such term is defined in 1933 Act Rule 433(h)(4). An emerging growth company is defined in Section 2(a)(19) of the 1933 Act as an issuer with less than $1,000,000,000 total annual gross revenues during its most recently completed fiscal year. The Trust meets the definition of an emerging growth company and consequently has submitted its Registration Statement on a confidential basis with the Commission. The Exchange will not commence trading in Shares of the Fund until the Registration Statement becomes effective.

The permissible price range for permitted TAS transactions is from 0.50 index points below the daily settlement price to 0.50 index points above the daily settlement price. The permissible minimum increment for a TAS transaction is 0.01 index points. See MGEX Rule 83.15 at http://www.mgex.com/​documents/​20210318-Rulebook.pdf.
