Drawdown Quant Interview Guide
Drawdown quant interview guide for peak-to-trough losses, max drawdown, recovery, path-dependent risk, examples, and limitations.
Candidates evaluating strategy risk beyond volatility.
Drawdown is path-dependent loss
Drawdown measures decline from a previous peak to a later trough. It captures pain along the path, which volatility or average return can hide.
Maximum drawdown is historical worst path
Maximum drawdown reports the largest observed peak-to-trough loss in the sample. It is useful, but it is sample-specific and does not bound future losses.
Concrete example
Two strategies can have similar average return and volatility, but one may suffer a long 30 percent drawdown while the other has smaller, faster recoveries.
Recovery matters
A drawdown discussion should include time to recovery, capital constraints, investor behavior, and whether losses coincide with stressful market conditions.
Common mistakes
Candidates often quote max drawdown as if it is a stable parameter. A stronger answer asks how long the sample is and what unobserved tail scenarios remain.
