What Is a Hedge Fund, What Is a Hedge, and Why Are They Called That
Hedge funds are named after a specific risk-management technique that most of them no longer use. Here's what the original hedge was, why it worked, and what the term actually means today.
The name “hedge fund” is one of finance’s great misnomers. Most hedge funds today do not hedge in any meaningful sense of the word. Some run pure directional bets. Others use leverage that amplifies risk rather than reducing it. A handful are barely distinguishable from aggressive mutual funds with a more expensive fee structure.
And yet the name stuck. To understand why, you have to go back to 1949 and the man who invented the structure.
Alfred Winslow Jones and the Original Hedge
Alfred Winslow Jones was a sociologist turned journalist turned portfolio manager. In 1949 he set up a private investment partnership and described his strategy as a “hedged fund” — a fund that explicitly hedged its market exposure.
His insight was simple and elegant.
Most investors of his era were either long the market or in cash. If the market went up, they made money. If it went down, they lost money. Their returns were overwhelmingly determined by the direction of the overall market rather than by any skill in picking individual stocks.
Jones thought this was a waste. If you were a good stock picker, your edge should come from picking the right stocks, not from being long during a bull market and unlucky during a bear one.
His solution was to go long stocks he believed were undervalued and short stocks he believed were overvalued — simultaneously. The long positions would profit if those stocks rose. The short positions would profit if those stocks fell.
The key was that the two positions roughly cancelled out the broad market exposure. If the market crashed 20%, his longs would probably fall and his shorts would probably fall more, cushioning the damage. If the market rallied 20%, his longs would probably rise and his shorts would probably rise less, meaning he still made money on the net differential.
This was the hedge. He was not hedging individual stock risk. He was hedging market risk — the systematic exposure to the direction of the overall market that every conventional long-only fund carries and cannot escape.
Jones also added leverage: he borrowed to amplify both the long and short books simultaneously, which increased potential returns without proportionally increasing market directional risk (since the hedge partially offset it).
What “Hedge” Actually Means
In the original and correct sense, a hedge is any position taken specifically to offset the risk of another position.
A farmer who sells wheat at a fixed forward price to protect against a price fall has hedged. A company that buys currency forwards to lock in exchange rates before an international purchase has hedged. Jones buying shorts alongside his longs to reduce market exposure had hedged.
The hedging logic has two components:
- Identify the risk you do not want — in Jones’s case, the risk that the whole market moves against him regardless of his stock-picking quality.
- Take an offsetting position — one that gains when that specific risk materialises.
Done properly, a hedge reduces variance without necessarily reducing expected return. If your edge comes from stock selection rather than market direction, removing market directional risk lets your actual edge surface in your returns. You are not giving up return — you are surgically removing the noise you cannot predict in exchange for clarity on the return you believe you can generate.
The Structure of a Hedge Fund
Beyond the strategy, Jones also established the legal and commercial structure that the industry still uses.
He organised his fund as a limited partnership. The outside investors are limited partners — they put up capital and share in profits and losses up to the value of their investment. Jones himself was the general partner — he managed the portfolio and took on unlimited liability for the fund’s obligations.
This structure gave the fund flexibility that registered investment companies (mutual funds) did not have: the ability to short, use leverage, trade derivatives, and invest in illiquid assets without the regulatory constraints imposed on public vehicles.
Jones charged a performance fee of 20% of profits — no management fee initially. The idea was alignment: he ate what he killed. This became the template for the industry’s fee structure, eventually evolving into the “two and twenty” model: a 2% annual management fee on assets under management plus 20% of any profits above a hurdle rate or high-water mark.
Because the structure requires investors to be sophisticated enough to understand what they are investing in and to bear losses without running to a regulator, hedge funds are generally restricted to accredited investors — individuals and institutions with sufficient wealth or financial expertise that regulators consider them capable of fending for themselves.
Why the Name Stuck Despite the Drift
Jones’s hedged fund worked. By the 1960s he had outperformed every mutual fund in the country over ten years and the strategy attracted imitators.
The imitators called themselves hedge funds because that was what Jones had built. But over time the definition drifted. The legal and commercial structure — limited partnership, performance fees, accredited investors — remained consistent. The actual strategy did not.
By the 1970s and 80s, global macro funds run by managers like George Soros and Paul Tudor Jones were operating with essentially pure directional bets on currencies, interest rates, and commodities. There was nothing mechanically hedged about Soros breaking the Bank of England in 1992 by shorting the pound. That was a concentrated directional conviction driven to its extreme. The word “hedge” had nothing to do with it.
Today, hedge fund is an administrative category more than a strategy category. It describes the legal wrapper — private partnership, limited investor access, performance fee, substantial flexibility in what instruments can be held — not the degree of market risk reduction inside it.
The Major Hedge Fund Strategies Today
The industry is broadly segmented by how they generate returns:
Long/Short Equity — the original Jones model. Long positions in favoured stocks, short positions in disliked ones. The market exposure (beta) can be anywhere from nearly zero (market neutral) to substantially positive. Many long/short equity funds today run meaningfully net long and have limited actual hedging relative to Jones’s original vision.
Global Macro — directional bets on interest rates, currencies, commodities, and equity indices. These funds trade in large liquid markets and make significant top-down calls on economic developments. They can and do hedge individual positions but the overall portfolio often has substantial directional exposure.
Quantitative / Systematic — strategy driven by models and algorithms rather than discretionary judgement. This includes statistical arbitrage, factor investing, and trend following. Quant funds range from nearly market neutral to heavily directional depending on the strategy.
Event Driven — trading around specific corporate events: mergers and acquisitions, spinoffs, bankruptcies, earnings surprises. Merger arbitrage (buying the target, shorting the acquirer after a deal announcement) is a classic example that does have a natural hedge built in — but the hedge is against deal risk, not market risk.
Relative Value / Fixed Income Arbitrage — taking positions that profit from price discrepancies between related instruments. These strategies are often market neutral by design but can carry significant liquidity risk and leverage, as Long-Term Capital Management demonstrated in 1998.
Credit — investing in corporate bonds, distressed debt, and structured credit. Often not hedged in the Jones sense.
The Honest Accounting
Jones’s original insight — that market directional exposure is a source of noise rather than skill for a stock picker — remains valid and intellectually coherent. The hedge was not risk avoidance. It was risk isolation: removing the market risk in order to express only the stock-selection skill for which the manager was presumably being paid.
The problem is that genuine market neutrality is hard to maintain, expensive to hedge, and reduces the AUM-proportional management fee income during periods where the long book vastly outperforms. Many funds that launched as long/short have gradually drifted to net long as their businesses scaled and AUM grew.
At the same time, the 2-and-20 fee structure means the alignment that Jones originally intended — paid only for profits — has been partially replaced by the management fee, which runs regardless of performance. A fund charging 2% annually on 200 million a year before the first dollar of return. That changes incentive structures in ways Jones likely did not intend.
The term “hedge fund” now means: a private investment vehicle, accessible to sophisticated investors, with flexible investment mandates and a performance fee structure. Whether it actually hedges anything is a separate question that requires reading the fund’s strategy documentation rather than relying on what the name implies.
The name comes from where it started. Where it goes depends on who is running it.
