A hedge fund is a pooled investment vehicle that is privately organised and is administered by professional investment managers. It is different from another pooled investment fund, the mutual fund, in that access is available only to wealthy individuals and institutional managers. Moreover, hedge funds are able to sell securities short and buy securities on leverage, which is consistent with their typically short-term and high risk oriented investment strategy, based primarily on the active use of derivatives and short positions. US hedge funds are exempt from Securities and Exchange Commission reporting requirements, as well as from regulatory restrictions concerning leverage or trading strategies.
