A hedge fund is a private investment pool that uses borrowed money and complex strategies to try to earn returns that beat the market

A hedge fund takes money from wealthy investors, borrows additional capital, and uses both to buy and sell stocks, bonds, currencies, and other assets. The fund manager makes the trading decisions and keeps a percentage of the profits — typically 20 percent. Unlike a mutual fund, which is regulated and open to ordinary investors, a hedge fund operates with fewer rules and accepts only accredited investors (people with high net worth or income). The word "hedge" originally meant protecting one investment by betting against another, but modern hedge funds use that term loosely and pursue many different strategies.

The core difference from a regular investment fund is leverage — the ability to borrow money to amplify gains. If a hedge fund has $100 million from investors and borrows $200 million, it controls $300 million in assets. When those assets rise 10 percent, the fund gains $30 million instead of $10 million. But when assets fall 10 percent, the losses are also magnified. This is why hedge funds can produce outsized returns or catastrophic losses.

Key Takeaways

  • Hedge funds borrow money to control more assets than investors actually put in, which magnifies both gains and losses.
  • The fund manager typically takes 20 percent of profits plus an annual fee of 1 to 2 percent of assets under management.
  • Hedge funds use strategies like short selling (betting a stock will fall), options trading, and buying undervalued companies that mutual funds cannot use.
  • Your money is usually locked in for a set period — often one to three years — and you cannot withdraw it on demand like a mutual fund.
  • Hedge funds are lightly regulated compared to mutual funds, which means less investor protection but also more freedom for the manager to pursue unconventional bets.

How money flows in and out of a hedge fund

An investor writes a check to the hedge fund and becomes a limited partner. The fund manager (the general partner) invests that money alongside some of their own capital. The investor's money sits in the fund for a set lockup period — commonly one to three years — during which you cannot withdraw it. After the lockup ends, many funds allow withdrawals on a quarterly or annual basis, but you usually have to give 30 to 90 days' notice.

The fund charges two layers of fees. The management fee is typically 1 to 2 percent of your total investment per year, paid whether the fund makes money or loses it. On top of that, the manager takes a performance fee — usually 20 percent of any profit the fund earns. If your $1 million investment grows to $1.2 million in a year, you pay the management fee on the full $1 million, and the manager takes $40,000 (20 percent of the $200,000 gain). The remaining $160,000 profit is yours.

This fee structure is why hedge fund managers can become extremely wealthy. A manager running a $1 billion fund with $100 million in annual gains collects $20 million in performance fees alone, plus $10 to $20 million in management fees.

The strategies hedge funds use to make money

Long/short equity is the most common approach. The manager buys stocks they think will rise (long positions) and borrows and sells stocks they think will fall (short positions). If both bets work, the fund profits on the way up and on the way down. A mutual fund can only buy stocks, so it makes money only when prices rise.

Arbitrage exploits price differences. If a stock trades at $50 on one exchange and $50.50 on another, the fund buys the cheaper one and sells the expensive one simultaneously, pocketing the 50-cent difference across thousands of shares. Merger arbitrage bets that a deal will close at the announced price — if Company A agrees to buy Company B for $60 per share, the fund buys Company B at $58, betting the deal will complete.

Distressed debt means buying bonds or loans from companies in financial trouble, often at steep discounts. If a company owes $100 million and is heading toward bankruptcy, its bonds might trade at 40 cents on the dollar. The fund buys them, works with management to restructure, and sells them at a higher price or holds them through recovery.

Event-driven strategies bet on corporate actions like spinoffs, bankruptcies, or management changes. Macro strategies make large bets on economic trends — for example, shorting a currency the manager believes will weaken or buying government bonds ahead of an interest rate cut.

Why hedge funds use borrowed money

Leverage amplifies returns when the manager's bets are correct. A hedge fund with $100 million from investors might borrow $200 million from banks, giving it $300 million to deploy. If those assets return 10 percent, the fund gains $30 million. After paying interest on the borrowed $200 million (say, 5 percent, or $10 million), the net gain is $20 million on the original $100 million investment — a 20 percent return instead of 10 percent.

The danger is that leverage works both ways. If the $300 million in assets falls 10 percent, the fund loses $30 million. After paying the $10 million interest, the loss is $40 million against the original $100 million investment — a 40 percent loss. Lenders also have the right to demand repayment if the fund's assets fall below a certain threshold, forcing the manager to sell positions at the worst possible time.

This is why some of the largest hedge fund collapses have been spectacular. Long-Term Capital Management, which borrowed heavily to bet on bond prices in 1998, lost $4.6 billion in a matter of weeks when its models failed.

How hedge funds differ from mutual funds and ETFs

A mutual fund is open to any investor, charges lower fees (typically 0.5 to 1 percent annually), and is heavily regulated by the Securities and Exchange Commission (SEC). You can withdraw your money daily. A mutual fund manager cannot use leverage, cannot short sell, and must hold a diversified portfolio. These restrictions protect ordinary investors but limit the manager's ability to pursue unconventional strategies.

A hedge fund accepts only accredited investors (those with $200,000 in annual income or $1 million in net worth, excluding home equity), charges much higher fees, and operates with minimal SEC oversight. The manager can use leverage, short sell, concentrate bets in a few positions, and pursue illiquid investments. Your money is locked up for years. The tradeoff is potential for higher returns — or larger losses.

An exchange-traded fund (ETF) is like a mutual fund but trades on a stock exchange throughout the day. Most ETFs are passive (they track an index) and charge very low fees. Some ETFs use leverage or short selling, but they are still regulated like mutual funds and open to all investors.

The risks of investing in a hedge fund

Leverage can wipe out your investment. If a hedge fund borrows heavily and its bets go wrong, losses can exceed 50 percent in a single year. You have no daily price quote like you do with a mutual fund, so you may not know the true value of your investment until the fund reports quarterly results.

Illiquidity is a real constraint. Your money is locked up for years, and even after the lockup period ends, you may have to wait months to withdraw. If the fund faces large redemptions from other investors, it may suspend withdrawals entirely to avoid forced asset sales.

Conflicts of interest abound. The manager takes 20 percent of profits, which incentivizes aggressive risk-taking. If a bet goes wrong, the manager's own capital is usually small compared to investor money, so they have less to lose. Some hedge funds have also engaged in fraud — Bernie Madoff's hedge fund was a Ponzi scheme that stole $65 billion.

Hedge funds are less transparent than mutual funds. You receive limited information about holdings and strategies, and the fund is not required to disclose positions to regulators. This opacity makes it harder to assess risk.

How hedge fund performance is measured

Hedge funds report returns as a percentage gain or loss per year. A fund that turns $100 million into $120 million in a year reports a 20 percent return. But this number can be misleading because it does not account for the risk taken or the fees paid. A fund that returns 15 percent but uses extreme leverage to do so is riskier than one returning 12 percent with moderate leverage.

Investors often compare hedge funds to the S&P 500 or other stock market indexes. Many hedge funds underperform the market in bull markets (when stocks are rising broadly) because they are hedged — they hold short positions that lose money when the market rises. But they may outperform in bear markets (when stocks are falling) because those short positions gain. A hedge fund's goal is often to deliver steady returns with lower volatility, not to beat the market every year.

Survivorship bias distorts reported performance. Hedge funds that fail are removed from performance databases, so the average return of "all hedge funds" is higher than it actually is. A fund that loses 50 percent and closes is not counted in next year's average.

Frequently Asked Questions

Can I invest in a hedge fund with $50,000?

Most hedge funds require a minimum investment of $500,000 to $1 million, though some accept $100,000 or $250,000. You also must be an accredited investor — earning at least $200,000 per year (or $300,000 with a spouse) or holding $1 million in net worth excluding your home. If you do not meet these thresholds, you cannot invest in a hedge fund directly.

What happens if a hedge fund loses money?

You lose your investment proportionally. If a hedge fund drops 30 percent in a year, your $1 million investment becomes $700,000. You still pay the management fee on the remaining $700,000. The manager does not pay performance fees in losing years, but they keep the management fee regardless of performance.

How is a hedge fund different from a private equity fund?

A hedge fund trades actively — buying and selling positions frequently, sometimes holding them for days or weeks. A private equity fund buys entire companies or large stakes, holds them for years, and tries to improve operations before selling. Private equity funds are even less liquid than hedge funds and typically require larger minimum investments.

Do hedge funds always use leverage?

No. Some hedge funds operate with no borrowed money at all, relying only on investor capital. These funds have lower risk but also lower potential returns. The fund's strategy determines whether leverage makes sense — a long/short equity fund might use moderate leverage, while a distressed debt fund might use none.

Why would I invest in a hedge fund if mutual funds are simpler?

Hedge funds pursue strategies that mutual funds cannot — short selling, leverage, concentrated bets, and illiquid investments. In theory, this allows a skilled manager to earn higher returns or protect against market downturns. In practice, most hedge funds underperform low-cost index funds over long periods, especially after fees. The appeal is usually to wealthy investors seeking diversification or specific market exposure, not to beat the market.
