A hedge fund is a privately organized pooled investment vehicle that seeks returns by using a broader set of techniques than typical retail funds. Unlike mutual funds, hedge funds typically aim for absolute returns regardless of market direction and have flexibility to use short selling, leverage, derivatives, and concentrated positions. They are generally offered to sophisticated or accredited investors and institutions rather than the general public. Learn more about investment structures.

Characteristics and structure

Most hedge funds are organized as limited partnerships or limited liability companies, with professional managers making investment decisions on behalf of limited partners. Common features include performance-based compensation (historically exemplified by the "2 and 20" model), lock-up periods, notice periods for redemptions, and less public reporting than registered funds. Use of leverage and over-the-counter instruments can increase both potential gains and risks.

Common strategies

  • Long/short equity: buying undervalued stocks while shorting overvalued ones.
  • Global macro: bets on currencies, interest rates, and global economic trends.
  • Event-driven: opportunities from mergers, restructuring, or corporate actions.
  • Relative value: arbitrage between related securities.
  • Quantitative/algorithmic: systematic, model-driven trading.

Hedge funds emerged in the mid-20th century and expanded greatly with institutional demand and financial innovation. Notable episodes—such as major distress among highly leveraged funds—have shaped subsequent risk management and regulatory responses. Post-crisis reforms increased reporting and counterparty oversight in some jurisdictions, though regulation remains lighter than for mutual funds.

For investors, hedge funds can offer diversification and access to sophisticated strategies but also entail higher fees, lower liquidity, and greater opacity. Due diligence should assess strategy, risk controls, fee structure, and alignment of interests. For practical investor guidance and regulatory summaries see investor resources.
