Correlation Risk Portfolio Interview Guide
Correlation risk portfolio interview guide for correlation, stress correlation, diversification, regime shifts, examples, and checks.
Candidates explaining diversification failures and dependency changes.
Correlation risk is dependency risk
Correlation risk is the risk that relationships between assets or strategies change, especially when diversification is most valuable.
Stress periods can compress diversification
Assets that look weakly related in calm periods may sell off together under funding pressure, liquidity shocks, or common macro drivers.
Concrete example
A portfolio of separate equity signals may still have hidden market beta. During a broad selloff, correlations can rise and losses can cluster.
Check correlations by regime
Look at rolling correlations, crisis windows, factor exposures, scenario shocks, and dependence beyond linear correlation when stakes are high.
Common mistakes
Candidates often quote a single historical correlation. A stronger answer asks whether that estimate is stable and relevant to future stress.
