•   Credit Risk — The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a derivatives transaction or other transaction is, or is perceived to be, unable or unwilling to pay interest, repay principal on time, or defaults. The value of an investment in the Fund may change quickly and without warning as a result of issuer defaults or actual or perceived changes in the credit ratings of the Fund’s portfolio investments or to an issuer’s financial strength.

When you are getting started making actual trades, in general you should focus on making LIMIT ORDERS which will get FILLED by other traders. Not only will you pay lower fees this way, but you will also be making more composed trading setups because you aren't impatiently just market-buying or market-selling into the spread. So a general principle you should follow is to AVOID MARKET ORDERS WHEN YOU CAN! You will pay higher "taker" fees and you will be at the mercy of the spread which is a hidden fee.

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.
In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income (“UBTI”) to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on UBTI, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a return and pay tax on such income, and (iii) in the case of a foreign shareholder (defined below), will not qualify for any reduction in U.S. federal withholding tax. A shareholder will be subject to income tax on such inclusions without reference to any exemption therefrom otherwise available under the Code.
Trading directly on CME is not possible unless you are a broker yourself. This means that you have to pay a high fee – between thousands and hundreds of thousands of USD – to join CME. As an individual investor, you need to find a broker who trades on CME. You will then open an account with this broker – a margin account rather than a cash account because in options trading, there is a margin involved, as we have seen above. Because this poses a higher risk for the broker – in case you can’t settle your debts – these deals can only be done in special margin accounts and not cash accounts.
Because most ETFs are investment companies, absent exemptive relief or reliance on an applicable exemptive statute or rule, a Fund’s investments in such investment companies generally would be limited under applicable federal statutory provisions. Those provisions typically restrict a Fund’s investment in the shares of another investment company to up to 5% of its assets (which may represent no more than 3% of the securities of such other investment company) and limit aggregate investments in all investment companies to 10% of assets. A Fund may invest in certain ETFs in excess of the statutory limit in reliance on an exemptive order issued by the SEC to those entities or pursuant to statutory or exemptive relief and pursuant to procedures approved by the Board provided that the Fund complies with the conditions of the exemptive relief, as they may be amended from time to time, and any other applicable investment limitations.
•   Valuation Risk — In certain circumstances, portfolio holdings may be valued using techniques other than market quotations. The value established for a portfolio holding may be different from what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio holding for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio holding is sold at a discount to its established value.
ensure the delivery of the requisite number of Fund Shares through DTC to the Custodian by no later than 10:00 a.m. Eastern Time of the second Business Day (T+2) immediately following the transmittal date. Authorized Participants should be aware that the deadline for such transfers of Fund Shares through the DTC system may be significantly earlier than the close of business on the primary listing exchange. Those making redemption requests should ascertain the deadline applicable to transfers of Fund Shares through the DTC system by contacting the operations department of the broker or depositary institution affecting the transfer of Fund Shares. The Balancing Amount, if any, must be transferred in U.S. dollars directly to the Custodian through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by the Custodian no later than 2:00 p.m. Eastern Time on the second Business Day (T+2) immediately following the transmittal date. If the Custodian does not receive both the required Fund Shares and the Balancing Amount, if any, by 10:00 a.m. and 2:00 p.m., respectively, on the second Business Day (T+2) immediately following the transmittal date, such order will be deemed not in proper form and cancelled.
By now you may ask yourself, “If I think that the price of an asset is going to rise, why should I buy a call option and not the asset itself?” The answer is this: Options give you leverage. That means that with a limited amount of capital, you can profit much more by buying options than assets – but also lose much more. This is because a small difference in the price of the underlying asset immediately leads to a substantial change in the price of the derivative. For example, when pork belly prices rise from 1,000 USD to 1,100 USD (an increase of 10%), call options for 1,000 USD suddenly become much more valuable – their prices may rise from 10.5 USD to 105 USD. Thus, if you have invested all of your capital in pork bellies, you will win 10% – if you have invested in pork belly call options, you will pocket a 1,000% profit.
