What Is a Hedge Fund?

A hedge fund is a pooled investment fund that gathers money from a relatively small number of professional or wealthy investors and pursues returns using a wide and flexible range of strategies. The name is historical: early funds “hedged” by holding some investments expected to rise and others expected to fall, aiming to profit regardless of the market’s overall direction. Today the term covers a broad family of funds united less by a single technique than by their freedom to invest in almost anything, in almost any way.

How a hedge fund works

Like other pooled funds, a hedge fund combines investors’ capital and invests it according to a defined strategy. What sets hedge funds apart is the tools they are permitted to use. They can borrow money to amplify positions, a practice known as leverage; they can engage in short selling, profiting when an asset’s price falls; and they can use derivatives, contracts whose value derives from an underlying asset, to speculate or manage risk. These techniques can magnify gains but also magnify losses, which is one reason access is restricted.

Hedge funds are typically run by a management firm led by a portfolio manager. Investors’ money is often subject to lock-up periods, during which it cannot be withdrawn, and redemptions may be allowed only at set intervals. This gives managers the freedom to pursue longer-term or less liquid positions than a fund offering daily dealing could.

Who can invest, and how they are regulated

Hedge funds are generally not open to the general public. In the United States they are usually limited to “accredited investors” and institutions that meet income or wealth thresholds set by the Securities and Exchange Commission, on the reasoning that such investors can better absorb losses and assess complex risks. In the United Kingdom they are marketed to professional and sophisticated investors and overseen by the Financial Conduct Authority. Because their clientele is restricted, hedge funds face lighter disclosure and marketing rules than funds sold to ordinary savers, though managers and the funds themselves still fall within the regulatory perimeter.

Fees and strategies

Hedge funds are known for charging more than mainstream funds. A traditional model, often summarised as “two and twenty”, combines an annual management fee of around two per cent of assets with a performance fee of around twenty per cent of profits, though actual terms vary widely and have drifted lower in recent years. The performance fee is meant to align the manager’s incentives with investors’, but it also means costs can be high when a fund does well.

Strategies are diverse and include:

• Long/short equity, buying shares expected to rise while shorting those expected to fall.
• Global macro, betting on broad economic trends in currencies, rates and commodities.
• Event-driven, trading around mergers, restructurings or other corporate events.
• Relative value, exploiting price differences between related securities.

How hedge funds differ from mutual funds

The contrast with a mutual fund is instructive. Mutual funds are widely available to retail investors, are tightly regulated, offer daily dealing and generally avoid heavy leverage or short selling. Hedge funds are exclusive, more lightly regulated, less liquid and far freer in their methods. In short, mutual funds prioritise accessibility and standardisation, while hedge funds prioritise flexibility and pursue absolute returns.

Why they matter

Although hedge funds hold only a fraction of global investment assets, they are influential. Their trading can move markets, their demand for short selling and derivatives contributes to price discovery, and large institutions such as pension funds and endowments allocate to them in search of returns that do not simply track the stock market. They also attract scrutiny, since leverage can transmit stress through the financial system, a concern highlighted during periods of turmoil and every recession. For most individuals, hedge funds remain out of reach and largely of interest as a feature of how professional and institutional capital is managed.
