Short Selling Mechanics Interview Guide
Short selling mechanics interview guide for borrow, locates, margin, recalls, squeeze risk, long-short equity, and caveats.
Candidates discussing short books, long-short strategies, and equity execution constraints.
Short selling requires borrowed shares
To short a stock, a trader typically borrows shares, sells them, and later buys shares back to return them. Borrow availability and cost matter.
Shorts have asymmetric pain points
A short position can lose more than the initial sale proceeds if the price rises. Margin, recalls, squeeze risk, and borrow fees can force action.
Concrete example
A cheap-looking short can be unattractive if the borrow fee is high, shares are hard to borrow, or recall risk is large near an event.
Long-short strategies need short-side modeling
Backtests should include borrow constraints, short availability, fees, recalls, liquidity, and corporate actions on the short side.
Common mistakes
Candidates often treat shorting as simply negative shares. Strong answers mention locate, borrow fee, margin, recall, and squeeze risk.
