A long-short fund is an investment vehicle, typically a hedge fund, that simultaneously buys stocks expected to increase in value and sells short stocks expected to decrease. Buying "long" means you own the stock and profit if it rises. Selling "short" means you borrow shares, sell them, and profit if the price falls before you buy them back. Running both positions at the same time lets the fund generate returns from individual stock selection rather than depending on the entire market going up.
As of 2025, global hedge fund assets under management surpassed $5 trillion, with long-short equity strategies representing the largest sub-asset class within that universe. The strategy has been a cornerstone of professional investing for decades precisely because it gives fund managers more tools to express their views on individual companies.
The goal is not just to make money when markets rise. A well-run long-short fund aims to profit from the spread between its best ideas on the long side and its worst ideas on the short side, regardless of what the broader market does.
Consider a simplified example. A fund manager believes Company A, a technology firm trading at $100, is undervalued. They also believe Company B, a competitor in the same sector, is overvalued at $80. The fund buys Company A long and sells Company B short. If Company A rises to $120 and Company B falls to $60, the fund profits $20 per share on the long and $20 per share on the short, for a total gain of $40. This profit is independent of whether the technology sector as a whole went up or down.
Net exposure is the difference between the long portfolio and the short portfolio, expressed as a percentage of total capital. It tells you how much the fund's performance depends on overall market direction.
A fund with 70% long exposure and 30% short exposure has a net exposure of +40%, meaning it still benefits significantly from a rising market. A fund with 50% long and 50% short has near-zero net exposure and is called market-neutral. Most long-short equity funds operate with a positive long bias, typically between 30% and 60% net long, because managers generally find more attractive ideas on the long side than the short side.
Long-short funds carry specific risk categories that differ from traditional mutual funds. Morgan Stanley identifies four that every investor in this strategy needs to understand.
Long-short funds and market-neutral funds are related but not interchangeable. Market-neutral funds represent a more constrained version of the strategy, with long and short positions sized to achieve near-zero net exposure. Standard long-short funds maintain a positive market bias, which means they capture more upside in bull markets but also absorb more downside during corrections. The choice between them depends on how much market exposure you want as part of your overall portfolio.
Traditionally, long-short equity strategies were available only to institutional investors and high-net-worth individuals through hedge funds with minimum investments of $1 million or more. Fidelity's June 2025 launch of the Fidelity Managed Futures ETF and similar products reflect a broader trend of packaging sophisticated strategies into accessible, lower-cost exchange-traded fund wrappers. Several long-short equity exchange-traded funds now offer this exposure to retail investors at annual expense ratios well below traditional hedge fund fee structures.
