Risk Parity Quant Interview Guide
Risk parity quant interview guide for risk contribution, volatility scaling, correlation, allocation examples, leverage caveats, and mistakes.
Candidates discussing allocation by risk rather than capital.
Risk parity allocates by risk contribution
Risk parity aims for assets or groups to contribute similar amounts of portfolio risk. It is different from equal capital weighting because volatilities and correlations differ.
Volatility scaling is common
Lower-volatility assets may receive more capital so their risk contribution rises, while higher-volatility assets may receive less. Leverage can enter depending on the target risk.
Concrete example
If one asset is much more volatile than another, equal dollar weights can make the volatile asset dominate risk. Risk parity would reduce that imbalance.
Correlation still matters
Risk contribution depends on covariance, not just standalone volatility. If correlations change in stress, the intended risk balance can shift quickly.
Common mistakes
Candidates often say risk parity is safer by definition. A stronger answer mentions leverage, correlation shifts, estimation error, and drawdown behavior.
