What is a hedge fund? How it works, strategies, fees, risks and who can invest

• What it is: a private pooled fund with flexible strategies, leverage, short selling and derivatives, outside most mutual fund rules.
• Who can invest: in the U.S., mainly accredited investors, with income over $200,000 ($300,000 with a spouse or partner) or net worth over $1 million excluding the home.
• Fees: 1% to 2% a year plus 20% of profits in the classic model; HFR's industry averages were about 1.3% and just under 16% in early 2026.
• Liquidity: redemptions monthly, quarterly or yearly, often after a lock-up of one year or more, and they can be suspended.

The name comes from hedging. The fund usually credited as the first, launched by Alfred Winslow Jones in 1949, bought stocks it expected to rise and sold short others it expected to fall, so that a market drop would hurt less. Today the word covers very different funds, many of which do not hedge at all: what they share is a legal form, private and lightly regulated, and a fee model.

This guide explains how hedge funds work, their main strategies, who can invest, what they cost, their risks and how to check one before investing, with figures from the SEC and HFR.

What a hedge fund is

According to the SEC's investor bulletin, hedge funds pool investors' money and invest it to make a positive return, with more flexible strategies than mutual funds: many use leverage, short selling and other speculative practices that mutual funds rarely use. They are sold privately rather than to the general public, which exempts them from several rules designed to protect retail investors. Most do not register under the Investment Company Act of 1940, relying on exemptions for funds with no more than 100 investors or with only “qualified purchasers”, individuals with at least $5 million in investments. They do not publish a daily price and follow no standard method to report performance.

They are not unregulated, though. Their managers are subject to the same anti-fraud rules as everyone else and owe a fiduciary duty to the funds they manage; above a certain size, they register with the SEC as investment advisers and file Form ADV, which anyone can read on the SEC's Investment Adviser Public Disclosure site.

The main hedge fund strategies

HFR, which tracks the industry, sorts hedge funds into four broad families. Their assets at the end of September 2026:

In total, industry capital reached $5.64 trillion, its 16th consecutive quarterly increase, as $34.5 billion of new money more than offset $27.4 billion of performance losses; HFR's equal-weighted index of hedge funds slipped 0.6% over the quarter (HFR, October 22, 2026). A fund of hedge funds invests in several hedge funds instead of individual securities, and adds its own layer of fees.

Who can invest in a hedge fund

In the United States, private funds are generally reserved for accredited investors. For an individual, the SEC's criteria are:

• Income over $200,000, or $300,000 with a spouse or partner, in each of the last two years, with the same level expected this year;
• Net worth over $1 million, alone or with a spouse or partner, excluding the primary residence;
• Professional licenses in good standing: Series 7, Series 65 or Series 82;
• Knowledgeable employees of the fund itself.

Funds that rely on the second exemption go further and accept only qualified purchasers. Everyone else can reach some of the same strategies through mutual funds and ETFs often called “liquid alternatives”: they are open to all, with daily liquidity and the protections of the Investment Company Act, including limits on borrowing, and their results and fees vary widely from one fund to another.

What hedge funds cost

The classic model is “2 and 20”. The SEC describes an annual management fee of 1% to 2% of assets plus a performance fee of 20% of profits, higher than mutual fund fees, and warns that a performance fee can push a manager to take more risk. Fees have come down: HFR estimated the industry-wide averages at 1.32% for the management fee and about 15.8% for the incentive fee in the first quarter of 2026. Many funds charge the performance fee only on gains above their previous peak, a rule known as a high-water mark.

Take $100,000 in a fund charging 1.5% and 20% that gains 10% before fees in a year. The management fee takes about $1,500; the performance fee takes 20% of the remaining $8,500 of gain, or $1,700. The investor keeps about $6,800, a 6.8% return instead of 10%. Exact calculations differ from fund to fund, which is why the offering documents matter, and a fund of hedge funds adds a second layer of fees on top.

The risks

• Leverage: borrowing magnifies gains and losses and can turn a conservative strategy into a very risky one.
• Liquidity: withdrawals are limited, often after a lock-up of a year or more, and the fund can suspend them during market stress.
• Valuation: illiquid holdings are hard to price, managers often have wide discretion, and that valuation also sets their fees.
• Performance reporting: there is no standard method, and figures may be estimates or exclude fees.
• Concentration and opacity: some funds hold a few large positions and disclose little about them.
• Manager risk: the SEC's enforcement cases include managers who hid conflicts of interest, took excessive fees or diverted investors' money.

The best-known failure remains Long-Term Capital Management, a fund run by renowned traders and economists: heavily leveraged, it lost most of its capital in a few months in 1998, and the Federal Reserve Bank of New York brought its lenders together to organize a rescue.

How to check a hedge fund before investing

1. Read the offering memorandum and subscription documents: strategy, where the fund is based, risks, fees, expenses and conflicts of interest.
2. Understand the strategy, and whether it uses leverage, derivatives or short selling.
3. Ask how assets are valued and how performance is calculated, before or after fees.
4. Check the redemption terms: frequency, notice period, lock-up, redemption fees, power to suspend.
5. Research the manager on the SEC's Investment Adviser Public Disclosure site and on FINRA BrokerCheck.
6. Ask where the assets are held, with which custodian, and whether an independent auditor verifies them every year.

Hedge funds or index funds?

Hedge funds offer something different from the market: returns that depend less on whether stocks rise or fall, sometimes with smaller swings. They do not promise to beat a stock index, and their fees take a large share of what they earn. For most savers, who cannot invest in them anyway, a low-cost diversified index fund remains the usual core of a long-term portfolio, as the guide on index funds, ETFs and mutual funds explains. Accounts and priorities are covered in the guides on brokerage accounts and on where to invest money.

Hedge funds outside the United States

In the European Union, hedge funds are alternative investment funds governed by the AIFM directive and generally reserved for professional investors; each country sets the conditions for individuals. In France, the AMF states that professional funds are open to an individual who invests at least €100,000, or through a discretionary management mandate; in Spain, the threshold is generally €100,000 too. Some UCITS funds sold to the public use alternative strategies within the limits of European rules.
