Long-short equity.

In plain English

Long-short equity runs two books at once, one holding shares the manager expects to gain and one holding borrowed shares sold in the hope of buying them back cheaper. The long book expresses what the manager thinks is undervalued and the short book what is overvalued. Returns come from the spread between the two books rather than from market direction alone, and part of the market's overall movement is offset. Most long-short funds keep net long exposure, meaning the long book is bigger, so they still fall in a broad decline, usually by less than the index.

01Why it matters

Short positions can lose more than the amount committed, since a stock can keep rising, and these funds typically charge far higher fees than an index fund, so the strategy has a high bar to clear before it adds anything.

02The math, step by step

A fund is 100 long and 40 short, so net exposure is 60. If the longs rise 10 percent and the shorts rise 4 percent, the gross result is 10 minus 1.6, roughly 8.4 percent before fees and borrowing costs.
