Use Case — Equity Factor Tilt Review

Given portfolio weights, benchmark weights, and a value-factor score per holding: 1. calculate active share 2. calculate the portfolio's and benchmark's value-factor exposure (pm.factors.portfolio_factor_exposure) 3. calculate the active style tilt (pm.equity.factors.style_tilt) 4. calculate shareholder yield for the largest overweight name 5. decide whether the fund's active share is explained mostly by this single style tilt, or by stock-specific bets uncorrelated with it
