Hedge funds, explained.

There is no statutory definition of a hedge fund. What the label captures is a private, actively managed pool sold only to qualified investors and freed, by that private placement, from most of the constraints that bind retail funds. Six features recur.

• Liquid instruments. Invests in liquid assets: listed securities, bonds, indices, commodities, and increasingly cryptocurrencies.
• Flexible and higher-risk. Far more flexible, and higher-risk, than mutual funds.
• Leverage. Typically uses leverage to amplify returns.
• Two-part fees. Charges a management fee (1–2%) and a performance fee (commonly 15–20%).
• Qualified investors only. Offered only to qualified investors; offshore vehicles typically require at least US$100,000.
• Two regulated acts. Selling interests in the fund and managing its assets are regulated separately worldwide.

The first hedge fund is generally credited to Alfred Winslow Jones, a Harvard graduate who launched his vehicle in 1949.

Jones used a limited partnership, sidestepping the rules that bound mutual funds, and combined leverage to buy shares with short positions to hedge market swings. That hedged long/short book is the origin of the term, which entered common use after Carol Loomis profiled him in Fortune in 1966. By the end of the 1960s, imitators including Michael Steinhardt, George Soros, and Ray Dalio had founded their own funds.

Hedge funds sit in the middle of the risk/return field: above money-market, index, and mutual funds, below private equity and venture capital. Risk and return rise together, so the fund types line up along the diagonal.

In 2007 Warren Buffett bet US$1 million that an S&P 500 index fund would beat five funds-of-funds holding stakes in more than 200 hedge funds. The funds led early in 2008, then trailed the index over the following nine years.

Managers report performance against benchmarks and against risk. Four measures recur.

• Cumulative performance. The aggregate % change in NAV over a period, benchmarked against an index such as the S&P 500.
• Beta and alpha. Beta measures portfolio risk against the market (1 = same, <1 = less risky, >1 = riskier). Alpha is the excess return over the benchmark for that risk.
• Sharpe ratio. Return relative to risk; useful for comparing portfolios at different risk levels. Higher is better.
• Drawdown. The largest peak-to-trough decline in NAV; investors weigh its severity and duration as a gauge of downside protection.

The difference is not only where hedge funds sit on risk/return, but how they are built, who can invest, and how investors get their money back.

The industry has roughly quadrupled since the 2008 crisis, passing US$6 trillion in 2025.

U.S.-based managers run roughly 60% of global hedge fund AUM in 2025. The concentration is even sharper at the very top.

For crypto strategies, domiciliation is highly concentrated, and still tilting toward one jurisdiction.

A fund pools investors in one of three vehicles. The choice drives liability, tax treatment, and how interests are issued.

Every hedge fund is the same handful of parties bound by a few agreements. What changes is the routing, driven by the tax profile of the investors. The standard structure is below; hover any entity to see what it is and why it sits there.

Crypto strategies add a licensing layer, extra documentation, and a specialist provider stack on top of the usual fund machinery.

Five offshore centres carry most of the market, each offering a ladder of fund types from lightly regulated private vehicles to fully authorised retail funds. The Cayman Islands ladder is below; the other four centres, Gibraltar, BVI, Jersey and Guernsey, load in the same table.

Any offering of securities to U.S. investors, including interests in an offshore fund, must be registered with the SEC or fit an exemption. Regulation D (1982) created safe harbours; Rule 506(b) is the one most hedge funds use.

Beyond Regulation D sit Regulation S (offshore), Regulation CF (crowdfunding), and Regulation A. Each differs on who can invest, whether you can advertise, and resale.

Three different tests gate three different things, who can invest, whether the manager can charge a performance fee, and which Investment Company Act exemption the fund relies on.

A U.S. hedge fund manager operates in one of two adviser tiers. The line that matters most is US$150M of private-fund AUM.

Two fees drive the economics: a management fee on assets that covers operating costs, and a performance fee that is the manager’s real upside. The classic “2 and 20” has drifted lower.

And here is how a single year’s return splits between investors and the manager. Enter the fund’s terms, drag the annual gross return, and watch the two-and-twenty math play out, hurdle included.

A cluster of defined terms governs how investors enter, how the performance fee is struck, and how and when money can leave.

Standing up and running a stand-alone U.S. fund splits into one-time setup and recurring obligations across six workstreams.

Six cross-cutting questions shape almost every fund: tax, marketing, who regulates the manager and the fund, internal compliance, and trade operations.

• Taxation. The fund vehicle is untaxed: either tax-transparent (a U.S. partnership/LLC) or established in a zero-tax jurisdiction (BVI, Cayman). Structure around the key investors’ tax position; check whether the asset class triggers special rules.
• Marketing and fundraising. Capital is raised by offering shares/interests, securities of a non-public company, regulated in each jurisdiction of offer. Generally not offered to retail; sold by private placement to accredited investors.
• Regulating the management company. U.S. managers register with the SEC, file as ERAs, or register at state level (e.g. New York). BVI and Cayman require real economic presence under economic-substance rules.
• Regulating the fund. Many jurisdictions regulate internal operations, AML/KYC and insider-trading policies, qualified custody, regular audits. Some rules apply simply because the fund accepts investors from a jurisdiction (U.S., EU, U.K.).
• Internal compliance. The fund should have compliance procedures and, ideally, a CCO maintaining a manual of mandatory, voluntary, and operational obligations.
• Trade operations. Relationships with the trade-operations team (in-house or outsourced) should be formalized, execution, settlement, reconciliation, reporting. Contracts matter on compensation, confidentiality, and asset security.

A fund sits at the centre of a small roster of outside providers, some mandatory, some strategic.

Launch runs as a roughly three-month critical path across seven parallel workstreams, business plan, service providers, team, office, marketing, IT, and compliance.
