Hedge Fund
Also known as: Absolute return fund
Not an asset but a licence: pooled capital free to go long, short, levered and anywhere — strategies as the product.
1 · SnapshotThe one idea to remember
2 · BeginnerWhat is it, really?
A hedge fund is a pool of money that is allowed to do almost anything. That is the whole point of it. It can bet that a price will fall as easily as that it will rise. It can borrow to make its bets bigger. It can put half the fund into one idea. It can trade any market on this site. Ordinary funds are fenced in on every one of those; a hedge fund is not.
The name is a leftover. Alfred Winslow Jones set up a fund in 1949 that paired bets up with bets down, so that the market itself stopped mattering — he had hedged it away. Plenty of funds that carry the name today hedge nothing whatsoever.
What you are actually buying is a strategy and the people running it. It is not an asset class the way shares or bonds are. Some funds buy shares they like and sell short ones they don't. Some bet on interest rates and currencies around the world. Some trade the gap between a bond and the insurance on it. Some simply follow whichever trend is running. Some wait for takeovers and bankruptcies. And the firms that now dominate — Citadel, Millennium — run dozens of small teams at once under one shared set of risk limits.
The selling point is that the returns do not follow the stock market. For some strategies that is true. For others it is a line in a brochure. The standard fee is 2% of your money every year plus 20% of any gain, and after those fees the average hedge fund has done worse than a plain index fund since 2008. The best platforms, meanwhile, have gone on compounding. The average tells you almost nothing here; the gap between the best and the worst is the story.

The strategy map
| Family | Bet | Typical profile |
|---|---|---|
| Equity long/short | Stock selection, both directions | Some market beta, single-name risk |
| Global macro | Rates, FX, commodities via top-down views | Lumpy, crisis-friendly |
| Trend/CTA | Momentum across futures | Long droughts, crisis convexity |
| Relative value/arb | Pricing gaps (converts, curves, bases) | Steady carry, tail blowups (LTCM's family) |
| Event-driven | Mergers, restructurings | Deal-break risk, deal-cycle-dependent |
| Multi-strategy platform | All of the above + risk discipline | The current industry endgame; pass-through fees |
Terms that matter
Management fee (1–2%; platforms charge "pass-through" costs instead, often totalling 3–8%), incentive fee (15–20%+) with high-water marks; redemption terms (monthly/quarterly with notice, gates in stress — liquidity mismatch killed many in 2008); leverage via prime brokers.
How institutions actually use them
Less "beat the market" than portfolio engineering: trend and macro for crisis convexity, relative value as bond substitutes, market-neutral as uncorrelated carry — evaluated on correlation and drawdown behaviour, not headline return.

Performance measurement done properly
Hedge fund indices overstate returns (survivorship, backfill bias — worth 2–4%/yr). Serious evaluation regresses returns on tradable factor proxies:
What the symbols mean
- Ra return
- ta point in time
- rthe interest rate, per year
- alphareturn beyond what the market exposure explains
- betahow much a holding moves with the market
- Fthe forward or futures price
Much of the industry's "alpha" decomposes into cheaply replicable alternative betas (short vol, FX carry, trend) — the basis of the liquid alt-beta products that undercut fees. Residual alpha concentrates in capacity-constrained strategies and the platform giants' infrastructure edge.
The platform model's mechanics
Multi-managers run pod structures: tight drawdown limits per team (cut at −5%), centralised risk netting, leverage 5–10x on market-neutral books. The model manufactures consistency but synchronises deleveraging — pod-shop crowding unwinds (e.g. quant equity events) are the new systemic signature, monitored via prime-broker data.
Risk beyond volatility
Left-tail properties dominate: short-vol strategies exhibit high Sharpe until they don't (peso problem); illiquid holdings + liquid redemption terms create run dynamics; leverage makes funding terms (margin, rehypothecation) the true capital structure. Due diligence weight: operations and counterparty structure ≥ strategy narrative — most fund deaths are operational.
The formulas above are standard textbook formulations, simplified for teaching. They explain the mechanism — they are not a valuation tool, and they will not reproduce a dealer’s price.
