What Are Hedge Funds and How Do They Work?

Hedge funds are private investment pools that raise money from wealthy individuals and institutions and deploy it across almost any asset using strategies that ordinary mutual funds can’t touch. A hedge fund manager can borrow heavily, bet against stocks, trade derivatives, and shift capital across markets worldwide. In return for that flexibility, investors pay high fees, have to meet federal wealth or income thresholds to get in, and generally can’t pull their money out on demand. Understanding what hedge funds are and how they work comes down to five things: how they’re organized, what they invest in, who’s allowed to participate, what it costs, and how hard it is to get your money back.

How a Hedge Fund Is Organized

Most hedge funds are set up as limited partnerships. The manager is the general partner and makes every trading decision. Investors come in as limited partners: they put up capital but have no say in what the fund buys or sells. Managers typically invest a meaningful share of their own wealth alongside investors, so both sides win or lose together.

The reason hedge funds can operate so freely is that they avoid registering as investment companies under the Investment Company Act of 1940. They do this by relying on one of two exemptions. A fund using Section 3(c)(1) can take up to 100 investors, who generally must be accredited. A fund using Section 3(c)(7) has no cap on investor count but limits participation to qualified purchasers, a much higher wealth bar.1Office of the Law Revision Counsel. 15 USC 80a-3 – Definition of Investment Company Those exemptions are what let hedge funds skip most of the regulatory apparatus that governs mutual funds.

Entry minimums start around $100,000 and can run into the millions, which puts hedge funds out of reach for most people even when they technically qualify.

What Hedge Funds Invest In

Managers have wide latitude, but a handful of strategies dominate the industry. Many funds mix them or shift approaches as conditions change.

  • Long/short equity: buying stocks expected to rise while short-selling stocks expected to fall. The short positions are meant to offset losses when markets drop. This is the most common hedge fund strategy.
  • Global macro: large directional bets on currencies, interest rates, commodities, or whole economies based on macroeconomic analysis. These funds move fast across asset classes and borders.
  • Event-driven: targeting specific corporate situations such as mergers, spin-offs, or bankruptcies, looking for gaps between where a security trades and where it should trade once the event resolves.

Leverage, Short Selling, and Derivatives

What sets hedge funds apart from conventional investing is the toolkit. Leverage lets a fund borrow against existing assets to control a much larger position than its cash alone would support. Gains get amplified. So do losses. The SEC’s reporting definition of a hedge fund captures the idea: a fund that can borrow more than half its net asset value, or have gross exposure exceeding twice its net value.2SEC.gov. Form ADV – General Instructions

Short selling lets a manager profit from falling prices by borrowing a security, selling it, then buying it back later at a lower price. Derivatives like options and futures do double duty: hedging existing positions against losses, or placing speculative bets with less upfront capital. These tools create the potential for outsized returns and introduce risks that don’t exist in a simple buy-and-hold portfolio.

To make leverage work in practice, funds rely on large banks known as prime brokers for lending, trade execution, custody, and clearing. The prime broker extends credit and holds the collateral. A prime broker’s distress can freeze a fund’s ability to trade, and a fund’s collapse can create significant losses for its prime broker.

Who Can Invest

Federal securities law limits hedge fund participation to investors who meet wealth or income thresholds. The premise is that wealthier investors can absorb losses and evaluate the risks of unregistered securities. There are two tiers.

Accredited Investors

To invest in a fund using the Section 3(c)(1) exemption, you generally need to be an accredited investor under Rule 501 of Regulation D. You qualify if your individual income exceeded $200,000 (or $300,000 jointly with a spouse or partner) in each of the past two years with a reasonable expectation of the same this year. Alternatively, you qualify with a net worth above $1 million, not counting your primary residence. Certain professional licenses, including Series 7, Series 65, and Series 82, also qualify you regardless of income or net worth.3U.S. Securities and Exchange Commission. Accredited Investors

Qualified Purchasers

The larger funds using Section 3(c)(7) require investors to be qualified purchasers. For an individual, that means owning at least $5 million in investments, excluding your home and any business property.4Cornell Law Institute. 15 USC 80a-2(a)(51) – Definition of Qualified Purchaser Institutional investors face a $25 million threshold. Because these funds have no cap on the number of investors, they can grow much larger than 3(c)(1) funds, which is why most of the biggest hedge funds in the world use this structure.

What Hedge Funds Cost

Hedge fund fees are substantially higher than what you’d pay for an index fund or an actively managed mutual fund. The traditional model, “2 and 20,” combines a 2% management fee on assets under management with a 20% performance fee on profits. Industry-wide, management fees have drifted lower in recent years, with the average closer to 1.4% to 1.5%, but most funds still charge 20% of profits. Either way, you pay the manager whether the fund makes money or not, and you give up a meaningful slice of gains when it does.

High-Water Marks

Most funds include a high-water mark, which blocks the manager from collecting performance fees until the fund passes its previous peak. If a fund drops 15% one year and recovers 10% the next, the manager earns no performance fee because the fund hasn’t reached a new high. Without this protection, a manager could earn performance fees on a recovery that only gets investors back to even.

Hurdle Rates

Some funds also set a hurdle rate, a minimum return the fund must clear before performance fees kick in. A fund with a 5% hurdle that returns 4% owes the manager no performance fee that year. Common benchmarks include a fixed percentage (often 3% to 6%) or a reference rate like SOFR or a Treasury yield. Hurdle rates keep investors from paying performance fees for returns they could have gotten from a savings account.

Why You Can’t Just Pull Your Money Out

A hedge fund investment is not liquid the way a brokerage account is. Multiple layers of restrictions govern when and how much you can withdraw.

Lock-Ups and Redemption Windows

Most funds impose an initial lock-up during which you can’t withdraw capital at all. A one-year lock-up is standard; some funds lock capital for two years or longer. After the lock-up expires, you can typically redeem only on specific dates, quarterly or sometimes annually. Nearly all funds also require advance notice of 30 to 45 days before a redemption date. Miss the notice window and you wait until the next one.

Gates and Side Pockets

Even when you’re eligible to redeem, the fund can limit how much leaves at once. A redemption gate typically caps total withdrawals at around 10% of the fund’s shares on any redemption date. If investors collectively ask for more than that, every request is cut proportionally.

Side pockets handle illiquid holdings. When a fund owns something that can’t be readily valued or sold, like debt in a bankrupt company, the manager can segregate it into a side pocket. You can redeem the liquid portion of your account, but your share of the side-pocketed asset stays locked until the manager sells it or it matures. Fund documents generally cap side pockets at 10% to 20% of net assets for any single position and around 40% in the aggregate.

How Hedge Funds Are Regulated

Hedge funds themselves are largely exempt from registration, but their managers are not. The regulatory framework centers on the adviser rather than the fund, and it has expanded significantly since the 2008 financial crisis.

Adviser Registration

Under Title IV of the Dodd-Frank Act, most hedge fund managers must register with the SEC as investment advisers under the Investment Advisers Act of 1940. Registration is required for advisers managing $150 million or more; those below that threshold are exempt from SEC registration, though they may still need to register with state regulators.5Cornell Law Institute. Dodd-Frank Title IV – Regulation of Advisers to Hedge Funds and Others Registration brings fiduciary duties, record-keeping requirements, and periodic SEC examinations.

Form ADV and Form PF

Registered advisers file Form ADV, a two-part disclosure. Part 1 covers ownership, business practices, affiliations, employee disciplinary history, and client information. Part 2 requires plain-English brochures describing fees, conflicts of interest, and strategies.6U.S. Securities and Exchange Commission. Form ADV Anyone considering a hedge fund should review the manager’s Form ADV before committing capital; it’s publicly available through the SEC’s Investment Adviser Public Disclosure database.

Advisers managing $1.5 billion or more in hedge fund assets also file Form PF, which gives the SEC and the Financial Stability Oversight Council detailed data on fund size, leverage, counterparty exposure, and risk concentrations.7U.S. Securities and Exchange Commission. Form PF Frequently Asked Questions Recent amendments to Form PF, with a compliance date in mid-2025, added current reporting for certain significant events such as extraordinary investment losses and large margin calls.8Federal Register.

When a hedge fund starts selling interests to investors, it must file a Form D notice with the SEC within 15 days of the first sale.9U.S. Securities and Exchange Commission. Filing a Form D Notice And though hedge funds are exempt from many mutual fund rules, they remain fully subject to federal anti-fraud law. The SEC regularly brings cases against managers who misrepresent performance, fabricate statements, or run Ponzi schemes.10U.S. Securities and Exchange Commission. Hedge Funds

How Hedge Fund Investments Are Taxed

Because hedge funds are partnerships, the fund itself pays no tax. Income, gains, losses, and deductions pass through to investors. Each year you receive a Schedule K-1 (Form 1065) reporting your share of the fund’s activity, and you use it to complete your own return.11Internal Revenue Service. 2025 Partners Instructions for Schedule K-1 (Form 1065) The K-1 splits income into categories (ordinary business income, short-term and long-term capital gains, dividends, interest), and each category lands on a different line or form. Most investors need a tax professional to handle a hedge fund K-1 correctly.

One wrinkle catches people off guard: you owe tax on your share of the fund’s income whether or not you received a distribution. If the fund had taxable gains during the year and you didn’t redeem, you still owe the IRS.11Internal Revenue Service. 2025 Partners Instructions for Schedule K-1 (Form 1065) This is sometimes called phantom income, and it can create cash flow problems for investors who weren’t expecting the bill.

Managers get a slice of profits as carried interest, which is technically a partnership allocation rather than a salary. Under 26 U.S.C. § 1061, carried interest qualifies for long-term capital gains rates only if the underlying assets were held more than three years, not the usual one-year threshold.12IRS. Section 1061 Reporting Guidance FAQs Gains on assets held three years or less get recharacterized as short-term and taxed at ordinary income rates.

The Risks

The SEC’s own investor guidance is blunt: hedge funds don’t have to provide the same level of disclosure as mutual funds, and it can be difficult to fully evaluate or verify the terms of your investment.10U.S. Securities and Exchange Commission. Hedge Funds That information gap is the starting point.

  • Leverage amplifies losses. A fund with 2x leverage that suffers a 30% decline in its positions loses 60% of investor capital. In extreme scenarios, losses can exceed the original investment.
  • Illiquidity. Between lock-ups, gates, and notice requirements, your money can be effectively trapped during the exact market conditions when you most want it back. The 2008 crisis saw numerous funds freeze redemptions entirely.
  • Limited transparency. Hedge funds generally don’t disclose holdings the way mutual funds must. You may not know exactly what the fund owns, how leveraged it is, or what counterparty risks it carries until those risks show up.
  • Fraud. The SEC has brought many cases involving managers who fabricated track records, ran Ponzi schemes, or sent fake account statements. The private nature of these funds makes fraud harder to detect early.10U.S. Securities and Exchange Commission. Hedge Funds
  • Underperformance after fees. Over most measured periods, the average hedge fund has trailed the S&P 500. Management and performance fees create a drag many managers never overcome. The largest funds have a somewhat better record, but results are inconsistent year to year.

This doesn’t make hedge funds inherently bad investments. Some strategies provide diversification and downside protection that traditional portfolios can’t replicate. But sales pitches tend to emphasize flexibility and absolute returns while playing down the costs, illiquidity, and information disadvantages built into the structure. Reading the fund’s offering memorandum, checking the manager’s Form ADV, and understanding every fee and redemption restriction before signing are the bare minimum before writing a check.
