Leveraged mutual funds seek to provide a multiple of the investment returns of a given index or benchmark on a daily or monthly basis. Inverse mutual funds seek to provide the opposite of the investment returns, also daily or monthly, of a given index or benchmark, either in whole or by multiples. Due to the effects of compounding, aggressive techniques, and possible correlation errors, leveraged and inverse funds may experience greater losses than one would ordinarily expect. Compounding can also cause a widening differential between the performances of a fund and its underlying index or benchmark, so that returns over periods longer than the stated holding period can differ in amount and direction from the target return of the same period. Consequently, these funds may experience losses even in situations where the underlying index or benchmark has performed as hoped. Aggressive investment techniques such as futures, forward contracts, swap agreements, derivatives, options, can increase fund volatility and decrease performance. Investors holding these funds should therefore monitor their positions as frequently as daily.
