Scenario Analysis Quant Interview Guide
Scenario analysis quant interview guide for scenario design, shocks, correlations, nonlinear exposures, interpretation, and examples.
Candidates evaluating portfolios under hypothetical market moves.
Scenarios ask what if
Scenario analysis evaluates portfolio behavior under specified market moves, such as rate shocks, equity selloffs, spread widening, or liquidity freezes.
Scenario design is judgment
Useful scenarios are plausible enough to inform decisions and severe enough to reveal vulnerabilities. They should match the portfolio exposures.
Concrete example
For a rates-sensitive portfolio, test parallel curve moves, curve steepening, credit spread widening, and correlation changes rather than one simple shock.
Nonlinear exposure matters
Options, leverage, stop-outs, funding, and liquidity constraints can make losses nonlinear. A scenario should capture those mechanics when relevant.
Common mistakes
Candidates often pick arbitrary shocks. Explain why the scenario is relevant, what assumptions it uses, and how the result would change decisions.
