Offshore fund

An investment vehicle that is domiciled outside the U.S. and has no limit on the number of non-U.S. investors it can take on. Although the fund's securities transactions occur on U.S. exchanges and are executed by a U.S. manager, or general partner, its administration and audits are conducted offshore -- usually in a tax haven like the Cayman Islands. Because it is administered outside the U.S., non-U.S. investors and such U.S. investors as pension funds and other tax-exempt entities aren't subject to U.S. taxes.

Opportunistic investment strategy

An approach that seeks to produce the greatest possible returns by making aggressive investments in the most-efficient products at a given time. Such funds typically hold their investments for five to 30 days, based on the momentum of the investments' values. They usually experience low volatility.
