In this series, we highlight several factors’ returns along with the broad index. These are factors – or stock characteristics – we monitor closely. Factor returns equal the difference in the average return of the highest ranked 10% (decile 1) of stocks minus the lowest ranked 10% (decile 10) within each metric. Returns are based on stocks that pass our screen for liquidity, price, and analyst coverage; therefore, some index constitutes are excluded (except for index return). Ranks are sector neutral and equal weight. Stocks are ranked one week before the return period date, with returns calculated for the following week.
