•   Equity and Market Risk — The equity markets are volatile, and the value of securities, swaps, futures, and other instruments correlated with the equity markets may fluctuate dramatically from day-to-day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, stocks may underperform other equity investments. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease.

Provide a list or diagram of all persons directly or indirectly controlled by or under common control with the Registrant. For any person controlled by another person, disclose the percentage of voting securities owned by the immediately controlling person or other basis of that person’s control. For each company, also provide the state or other sovereign power under the laws of which the company is organized.
Beneficial owners of Shares are not entitled to have Shares registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and are not considered the registered holder thereof. Accordingly, each Beneficial Owner must rely on the procedures of DTC, the DTC Participant and any Indirect Participant through which such Beneficial Owner holds its interests, to exercise any rights of a holder of Shares. The Trust understands that under existing industry practice, in the event the Trust requests any action of holders of Shares, or a Beneficial Owner desires to take any action that DTC, as the record owner of all outstanding Shares, is entitled to take, DTC would authorize the DTC Participants to take such action and that the DTC Participants would authorize the Indirect Participants and Beneficial owners acting through such DTC Participants to take such action and would otherwise act upon the instructions of Beneficial owners owning through them. As described above, the Trust recognizes DTC or its nominee as the owner of all Shares for all purposes. Conveyance of all notices, statements and other communications to Beneficial owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of Shares holdings of each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial owners holding Shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such

Each Fund has adopted certain investment restrictions as fundamental policies that cannot be changed without a “vote of a majority of the outstanding voting securities” of the Fund. The phrase “majority of outstanding voting securities” is defined in the 1940 Act as the lesser of: (i) 67% or more of the shares of the Fund present at a duly-called meeting of shareholders, if the holders of more than 50% of the outstanding shares of the Fund are present or represented by proxy; or (ii) more than 50% of the outstanding shares of the Fund. (All policies of a Fund not specifically identified in this Statement of Additional Information or its Prospectus as fundamental may be changed without a vote of the shareholders of the Fund.) For purposes of the following limitations, all percentage limitations apply immediately after a purchase or initial investment.

So far, these derivatives market have only been a niche occupied by crypto enthusiasts. That is until one of the newcomers, Crypto Facilities, and an incumbent in the derivatives market have joined forces: Crypto Facilities and the CME Group. The CME Group (controlling, for example, the Chicago Mercantile Exchange that has been around for more than a century) is a large-scale business that is officially regulated and audited by the US financial authorities. It settles its contracts in fiat money rather than cryptocurrency, thus enabling non-crypto experts to speculate on Bitcoin.
In general, a foreign corporation that is not engaged in and is not treated as engaged in a U.S. trade or business is nonetheless subject to tax at a flat rate of 30% (or lower tax treaty rate), generally payable through withholding, on the gross amount of certain U.S.-source income that is not effectively connected with a U.S. trade or business. There is presently no tax treaty in force between the United States and the jurisdiction in which any Subsidiary is (or would be) resident that would reduce this rate of withholding tax. Income subject to such a flat tax is of a fixed or determinable annual or periodic nature and includes dividends and interest income. Certain types of income are specifically exempted from the 30% tax and thus withholding is not required on payments of such income to a foreign corporation. The 30% tax generally does not apply to capital gains (whether long-term or short-term) or to interest paid to a foreign corporation on its deposits with U.S. banks. The 30% tax also does not apply to interest which qualifies as “portfolio interest.” Very generally, the term portfolio interest includes U.S.-source interest (including OID) on an obligation in registered form, and with respect to which the person, who would otherwise be required to deduct and withhold the 30% tax, received the required statement that the beneficial owner of the obligation is not a U.S. person within the meaning of the Code.
When a Fund purchases a put or call option on a futures contract, the Fund pays a premium for the right to sell or purchase the underlying futures contract for a specified price upon exercise at any time during the option period. By writing (selling) a put or call option on a futures contract, a Fund receives a premium in return for granting to the purchaser of the option the right to sell to or buy from the Fund the underlying futures contract for a specified price upon exercise at any time during the option period.
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[49] Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[50] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[51]
The tables below show performance examples of an UltraPro and UltraPro Short ProShares Fund that have investment objectives to correspond to three times (3x) and three times the inverse (-3x) of, respectively, the daily performance of an index. In the charts below, areas shaded lighter represent those scenarios where a Fund will return the same as or outperform (i.e., return more than) the index performance times the stated multiple in the Fund’s investment objective; conversely, areas shaded darker represent those scenarios where the Fund will underperform (i.e., return less than) the index performance times the stated multiple in the Fund’s investment objective.
Each Fund, from time to time, in the ordinary course of business, may purchase securities on a when-issued or delayed-delivery basis (i.e., delivery and payment can take place between 30 and 120 days after the date of the transaction). These securities are subject to market fluctuations and no interest accrues to the purchaser during this period. At the time a Fund makes the commitment to purchase securities on a when-issued or delayed-delivery basis, the Fund will record the transaction and thereafter reflect the value of the securities, each day, in determining the Fund’s NAV. Each Fund will not purchase securities on a when-issued or delayed-delivery basis if, as a result, it determines that more than 15% of the Fund’s net assets would be invested in illiquid securities. At the time of delivery of the securities, the value of the securities may be more or less than the purchase price.
Since a portion of the Fund’s assets are invested in short positions in bitcoin futures contracts, the Fund will likely decline in value when the price of bitcoin futures contracts goes up (unless such losses are offset by gains in the value of the Fund’s positions in other investments), a result that is the opposite from the results of taking long positions in bitcoin futures contracts.
I have worked with the CME in the past on product development (specifically CDS futures) and from my experience, they would not have missed anything this simple.  In fact, while I am not a huge fan of the concept of Bitcoin futures, as currently implemented, I do not expect any errors in the operation of the CME or CBOE futures contract.  I am sure that regulators will be questioning them on the back of the OKEX, as they should, and I am also quite positive the exchanges here will pass with flying colors.
The rights of indemnification under the Declaration of Trust may be insured against by policies maintained by the Trust, and shall be severable, shall not affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be a Covered Person, and shall inure to the benefit of the heirs, executors and administrators of such a person.

The Trust and the fund have obtained an exemptive order from the SEC allowing a registered investment company to invest in the Fund’s shares beyond the limits of Section 12(d)(1) subject to certain conditions, including that a registered investment company enters into a Participation Agreement with the Trust regarding the terms of the investment. Any investment company considering purchasing shares of the Fund in amounts that would cause it to exceed the restrictions of Section 12(d)(1) should contact the Trust.
* The “Fund Complex” consists of all operational registered investment companies under the 1940 Act that are advised by ProShare Advisors LLC and any registered investment companies that have an investment adviser that is an affiliated person of ProShare Advisors LLC.

In order to make sure that you actually have money in your margin account to settle the difference with Mortimer every day, you are required to put up an initial margin at the beginning of the contract. A lower sum, the so-called minimum margin or maintenance margin, is also defined by the broker. If the money in your margin account falls from the initial margin to the maintenance margin, it triggers a margin call: The broker requests you to fill up your margin account to at least the initial margin (of course, you may also put up more).
The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[28][31] Each block typically contains a hash pointer as a link to a previous block,[31] a timestamp and transaction data.[32] By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".[33] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
Recent bitcoin futures contract announcements from CBOE, CME, and Nasdaq have generated tremendous interest in digital assets. Bitcoin futures have been highly anticipated as they will provide traditional financial institutions with one of the first opportunities to meaningfully participate in the digital asset space via a regulated investment framework. It is an opportunity for Wall Street to catch up with Main Street on bitcoin. With the impending launch of U.S.-listed bitcoin futures, investors may wonder what the bitcoin futures curve might look like. Using information from existing digital asset derivative trading platforms such as Bitmex, OKCoin, CryptoFacilities, and BTCC (all exchanges outside of the Commodity Futures Trading Commission purview), MVIS Research has constructed an approximate curve based on non-U.S. bitcoin futures trading on these exchanges. These are real trading platforms revealing real volume.
Currently, Bitcoin futures have very high margin requirements. The Cboe requires 40% of the notional amount for maintenance margin, the CME requires 43%. Your broker will likely require more than that. The culprit behind these high requirements is Bitcoin’s high volatility—until that calms down the exchanges will protect themselves by requiring a bunch of up-front money. If you don’t come up with the money for a margin call they want to close out your position without leaving a negative balance.
that receive different proportions of the interest and principal distributions from a pool of mortgage assets. The Funds will only invest in SMBS whose mortgage assets are U.S. government obligations. A common type of SMBS will be structured so that one class receives some of the interest and most of the principal from the mortgage assets, while the other class receives most of the interest and the remainder of the principal. If the underlying mortgage assets experience greater than anticipated prepayments of principal, each Fund may fail to fully recoup its initial investment in these securities. The market value of any class that consists primarily or entirely of principal payments generally is unusually volatile in response to changes in interest rates.

!! WARNING !!! Note that on CryptoFacilities each contract is denominated by 1 BTC. So if you bought a fraction of BTC you can NOT perform a perfect hedge of the value. If you round the BTC you bought with start capital down, you will have slight overexposure LONG with the left-over BTC. If you round up and short an extra contract, you will have slight overexposure SHORT.
