Tracking Error Quant Interview Guide
Tracking error quant interview guide for active return volatility, benchmark-relative risk, active bets, examples, and limitations.
Candidates discussing benchmark-relative risk and portfolio deviations.
Tracking error measures active volatility
Tracking error is the volatility of returns relative to a benchmark. It captures how much a portfolio deviates from the benchmark path.
Active bets create tracking error
Sector tilts, factor exposures, security selection, leverage, and timing decisions can all increase tracking error. The source matters for interpretation.
Concrete example
A portfolio that matches benchmark return on average can still have high tracking error if it takes large offsetting active bets along the way.
Benchmark choice matters
Tracking error is meaningless without a benchmark. A portfolio may track one benchmark closely and another poorly because the reference exposure differs.
Common mistakes
Candidates often call tracking error total risk. It is benchmark-relative risk, so the benchmark and active exposures must be named.
