What Hedge Funds Do

Hedge funds are private investment pools that can bet on prices rising or falling, use leverage and trade almost anything. Here are the main strategies, how they charge and what their filings can and cannot tell you.

Private and flexible

A hedge fund is a private fund, usually open only to wealthy individuals and institutions. Unlike most mutual funds, it can sell short, borrow heavily, trade derivatives and hold concentrated positions. Many aim for returns that do not depend on the stock market rising.

General descriptions; many funds mix approaches.

Fees and results

Hedge funds have traditionally charged about 2% of assets a year plus 20% of profits, and some large multi-strategy funds pass through even higher expenses. After fees, the average hedge fund has trailed a simple stock index over long bull markets, though some funds have delivered strong risk-adjusted returns and helped cushion downturns.

Why individual investors watch them

Large managers must publicly disclose many of their stock holdings every quarter. Those filings let anyone see what famous investors own. The key is knowing what the filings show, what they hide and how old the information is, which the rest of this category covers.
