The Funds may invest in the securities of other investment companies, including exchange-traded funds (ETFs) and unit investment trusts (UITs), to the extent that such an investment would be consistent with the requirements of the 1940 Act or any exemptive order issued by the SEC. If a Fund invests in, and thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations.
An initial coin offering (ICO) is a controversial means of raising funds for a new cryptocurrency venture. An ICO may be used by startups with the intention of avoiding regulation. However, securities regulators in many jurisdictions, including in the U.S., and Canada have indicated that if a coin or token is an "investment contract" (e.g., under the Howey test, i.e., an investment of money with a reasonable expectation of profit based significantly on the entrepreneurial or managerial efforts of others), it is a security and is subject to securities regulation. In an ICO campaign, a percentage of the cryptocurrency (usually in the form of "tokens") is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often bitcoin or ether.[62][63][64]

Other forms of swap agreements that the Funds may enter into include: interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified level, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels.

Bitcoin has been on a tear this year, surging at least 1,000 percent in 2017.

The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.[18]
Having said that, bitcoin price action remains fraught with wild and inexplicable gaps, like a $400 drop and rise in an hour in the late hours of July 30, according to Bloomberg.  This particular trade, and unwind seems to have affected bitcoin pricing globally and likely impacted trading of the U.S. listed contracts as well.  Volumes and open interest seemed to have increased around the time of this large trade unwind.  It could be a coincidence, though I suspect that some smart traders, aware of the situation, put short trades on in these future contracts to take advantage of the forced unwind.
Investment in mortgage-backed securities poses several risks, including among others, prepayment, market and credit risk. Prepayment risk reflects the risk that borrowers may prepay their mortgages faster than expected, thereby affecting the investment’s average life and perhaps its yield. Whether or not a mortgage loan is prepaid is almost entirely controlled by the borrower. Borrowers are most likely to exercise prepayment options at the time when it is least advantageous to investors, generally prepaying mortgages as interest rates fall, and slowing payments as interest rates rise. Besides the effect of prevailing interest rates, the rate of prepayment and refinancing of mortgages may also be affected by appreciation in home values, ease of the refinancing process and local economic conditions. Market risk reflects the risk that the price of a security may fluctuate over time. The price of mortgage-backed securities may be particularly sensitive to prevailing interest rates, the length of time the security is expected to be outstanding, and the liquidity of the issue. In a period of unstable interest rates, there may be decreased demand for certain types of mortgage-backed securities, and each Fund invested in such securities wishing to sell them may find it difficult to find a buyer, which may in turn decrease the price at which they may be sold. Credit risk reflects the risk that a Fund may not receive all or part of its principal because the issuer or credit enhancer has defaulted on its obligations. Obligations issued by U.S. government-related entities are guaranteed as to the payment of principal and interest, but are not backed by the full faith and credit of the U.S. government. The performance of private label mortgage-backed securities, issued by private institutions, is based on the financial health of those institutions. With respect to GNMA certificates, although GNMA guarantees timely payment even if homeowners delay or default, tracking the “pass-through” payments may, at times, be difficult.

Bitcoin futures promise more flexibility for investors and potentially a more stable price. Yet, there is a chance that volatility could increase in the interim and while strategies like shorting and using leverage hold a lot of potential when used within the right infrastructure, they can be detrimental to smaller investors and, in the worst case scenario, could derail the market in dangerous ways.

All three DBRS rating categories for short term debt use “(high)”, “(middle)” and “(low)” as subset grades to designate the relative standing of the credit within a particular rating category. The following comments provide separate definitions for the three grades in the Prime Credit Quality area, as this is where ratings for active borrowers in Canada continue to be heavily concentrated.
Bitcoin and other cryptocurrencies have evolved from a playful experiment among technical experts to an established and growing branch of the global financial industry. This means that the times in which cryptocurrency traders and investors only concerned themselves with straightforward buying and selling are over. Derivatives are now entering the picture.
