What Is a Hedge Fund? How It Differs From a Mutual Fund

A hedge fund is a pooled investment vehicle that raises capital from a limited set of investors and pursues a broad, often aggressive mandate — including leverage, derivatives, short selling, and concentrated bets — in pursuit of returns that don’t move in lockstep with the broader market. The name is a historical artifact: the earliest funds literally tried to “hedge” market risk by pairing long and short positions, though most modern hedge funds pursue strategies far beyond that original idea.

Who can invest

Hedge funds are structured to avoid the heavy regulatory disclosure requirements that apply to funds sold to the general public, and in exchange they’re restricted to accredited investors — individuals and institutions that meet income, net worth, or professional thresholds meant to indicate they can absorb losses and don’t need the same regulatory protection as retail investors. This typically means institutional investors (pension funds, endowments, insurance companies), high-net-worth individuals, and family offices, rather than an everyday retail brokerage account.

This restriction is the structural reason hedge funds can do things a retail mutual fund generally cannot: use significant leverage, hold concentrated positions in a small number of securities, and take on illiquid or complex positions without the diversification and liquidity rules that protect retail investors in more heavily regulated fund structures.

Fee structure: “two and twenty”

Hedge funds are famous for a fee structure often summarized as “two and twenty”: a 2% annual management fee on assets under management, regardless of performance, plus a 20% performance fee on any profits generated. The management fee covers operating costs; the performance fee is meant to align the manager’s incentives with generating actual returns rather than just gathering assets.

Many funds also apply a high-water mark, meaning the performance fee only kicks in once the fund’s value exceeds its previous peak — a manager who loses money one year doesn’t collect a performance fee on merely recovering back to where investors started. These exact terms vary fund to fund and have compressed somewhat industry-wide as competition for capital has increased, but the two-and-twenty framing remains the standard reference point.

Common strategies

“Hedge fund” describes a legal and fee structure, not a single strategy — funds pursue very different approaches under that umbrella:

• Long/short equity — buying stocks expected to rise while shorting stocks expected to fall, aiming to profit from the spread regardless of overall market direction.
• Global macro — betting on broad economic trends: interest rates, currencies, commodities, driven by macroeconomic views rather than individual company analysis.
• Event-driven — positioning around specific corporate events like mergers, spinoffs, or bankruptcies, where the fund is betting on the outcome of a defined event rather than general market direction.
• Quantitative — using systematic, model-driven strategies executed algorithmically rather than discretionary human stock-picking.
• Distressed debt — buying the debt of financially troubled companies at a discount, betting on recovery or a favorable outcome in restructuring.

Hedge fund vs mutual fund vs private equity

These three get grouped together as “alternative investments” in casual conversation, but they differ in structure, liquidity, and strategy:

	Hedge fund	Mutual fund	Private equity
Investor eligibility	Accredited investors only	Open to the public	Accredited/institutional investors
Typical liquidity	Periodic (monthly/quarterly), often with lock-ups	Daily	Illiquid for years (fund lifespan)
Regulatory oversight	Lighter	Heavier (retail protections apply)	Lighter
Typical strategy	Broad — long/short, macro, derivatives	Long-only, diversified	Buying and operationally improving private companies
Fee structure	Management fee + performance fee	Management fee (expense ratio) only	Management fee + performance fee (“carry”)

Private equity and hedge funds share the accredited-investor restriction and a similar management-plus-performance fee structure, but they target fundamentally different assets: hedge funds mostly trade liquid, publicly traded securities, while private equity buys stakes in private companies directly and typically holds them for years while working to improve their operations before selling. Understanding how startup funding rounds work covers the earlier end of that private-company spectrum, before a company would be a plausible private equity target.

Risk and leverage

Because hedge funds can use leverage — borrowing to amplify the size of a position beyond the capital actually invested — both gains and losses scale accordingly. A fund that borrows to double its exposure doubles its percentage gains on a winning position and doubles its percentage losses on a losing one. This is a large part of why hedge fund failures, when they happen, tend to be dramatic rather than gradual: concentrated, leveraged positions that go wrong can erase a fund’s capital far faster than a diversified, unleveraged portfolio would. It’s also why the accredited-investor restriction matters as a policy matter — the strategies that make outsized returns possible are the same ones that make outsized losses possible.

The takeaway

A hedge fund is defined less by any single strategy and more by its structure: capital pooled from accredited investors, deployed with fewer regulatory constraints than a retail mutual fund, typically charging a management fee plus a performance fee. That freedom allows leverage, shorting, and concentrated bets that retail-facing funds generally can’t use, which is the source of both hedge funds’ potential for outsized returns and their potential for outsized losses.
