Long Short Equity Quant Interview Guide
Long-short equity quant interview guide covering long and short books, borrow, beta, factors, costs, examples, and risk.
Candidates discussing relative returns, constraints, borrow, and risk.
Long-short equity combines positive and negative views
A long-short equity portfolio buys securities expected to outperform and shorts securities expected to underperform over a horizon.
Shorting has practical constraints
Borrow availability, borrow fees, recalls, short-sale rules, and squeeze risk can change the attractiveness of the short book.
Concrete example
A strategy may go long top-ranked stocks and short bottom-ranked stocks while targeting beta, sector, and factor neutrality.
Risk comes from both sides
Longs can fall, shorts can rise, borrow can become expensive, and factor exposures can dominate intended stock selection.
Common mistakes
Candidates often ignore the short side. A strong answer includes borrow, liquidity, risk limits, and exposure controls on both sides.
