What Is Long/Short Equity?
A long/short equity fund holds long positions in stocks the manager believes are undervalued and short positions in stocks believed to be overvalued. Gains can come from the longs rising, the shorts falling, or both, which means the fund's returns depend more on the manager's stock selection than on the direction of the overall market.
The approach dates to Alfred Winslow Jones, who launched what is widely considered the first hedge fund in 1949 by combining long positions with shorts and leverage. His structure of hedged exposure plus a performance fee became the template for the modern hedge fund industry, and long/short equity remains its largest single strategy.
How the Strategy Works
Managers describe their positioning through gross and net exposure. A fund that is 100% long and 60% short has gross exposure of 160% and net exposure of 40%, meaning it still benefits modestly from rising markets but far less than an index fund. Market-neutral funds run net exposure near zero, while directional long/short funds might run net long 30% to 70% depending on their outlook.
Shorting introduces mechanics of its own. The fund borrows shares through a prime broker, sells them, and hopes to repurchase at a lower price, paying a borrow fee along the way. Because a short position loses money without limit if the stock keeps climbing, and crowded shorts can squeeze violently, risk management around position sizing and factor exposures is central to the job.
Why Long/Short Equity Matters
The strategy's appeal is delivering returns driven by skill, or alpha, rather than market direction, or beta. Multi-manager platforms such as Citadel and Millennium run dozens of long/short teams under tight risk limits, paying for consistent stock selection while hedging away broad market moves. Single-manager funds often run more concentrated, higher-conviction books in the value or growth tradition.
For young professionals, long/short equity is one of the most sought-after exits from investment banking and equity research. Interviews revolve around stock pitches, and candidates are expected to pitch both a long and a short with a clear view of valuation, business quality, and the catalyst that will move the stock. Understanding gross versus net exposure is table stakes in those conversations.
