Closet Indexing
An active fund that holds a portfolio close to its benchmark while charging active management fees.
How it is identified
Test: low active share and low tracking error combined with an expense ratio typical of active management
Unit
qualitative
In depth
A closet indexer cannot outperform by enough to cover its fee, because it barely deviates from the index — the arithmetic makes underperformance close to certain rather than merely likely. The diagnostics are active share, which measures the proportion of holdings differing from the benchmark, and tracking error, which measures how far returns deviate. An R-squared above 95% with a high expense ratio is the statistical signature. The problem is structural rather than dishonest: a fund large enough must hold the largest stocks in roughly index weights, so scale pushes funds toward the index whether or not the manager intends it.
Worked example
A fund with an R-squared of 96%, tracking error of 0.9% and an expense ratio of 1.8% is charging 1.6 points more than an index fund for returns that differ from the index by less than one point a year.
