ProShares Short QQQ(AMEX:PSQ)

PSQ makes a straight bet against the popular QQQ ETF by providing inverse exposure to the NASDAQ-100 index an index of 100 tech-heavy firms listed on NASDAQ that excludes financials. The fund uses a combination of swaps on the NASDAQ-100 ETF (QQQ), swaps on the index itself, and NASDAQ-100 futures to achieve this exposure. As with most inverse and leveraged products, PSQ is designed to provide this exposure on a daily basis, not as a long-term inverse bet against the index. Investors holding the fund for longer than a day will be exposed to the effects of compounding on returns, and will be unlikely to realize the stated exposure over extended periods of time.
