Factor Risk Model Quant Interview Guide
Factor risk model quant interview guide for factors, exposures, covariance, specific risk, attribution, examples, and validation.
Candidates explaining portfolio exposures and common risk drivers.
Factor models explain common risk
A factor risk model decomposes portfolio behavior into exposures to shared drivers plus specific residual risk that remains after those drivers.
Exposures make hidden bets visible
A portfolio may appear diversified by names while carrying large exposure to value, momentum, rates, beta, sector, or liquidity factors.
Concrete example
A long-short book can be dollar neutral but still have a large growth factor exposure. A factor model helps identify that risk.
Risk models need validation
Check whether predicted risk matches realized risk, whether factors are stable, and whether residuals contain unmodeled common structure.
Common mistakes
Candidates often treat factor labels as complete explanations. Factor models simplify reality and can miss tail, liquidity, or nonlinear risks.
