Weekly Factor Returns

A look at what factors influenced the market last week

Equities were flat-to-negative last week. The small cap Russell 2000 declined 1.08% while the large cap Russell 1000 declined 0.64%. The Russell MidCap was largely unchanged (-0.04%).

Factor returns were directionally similar across the capitalization ranges. One spread exceeded normal expectations.

Volatility was not favored. The most volatile stocks underperformed the least volatile, on average, in each index. Volatility was lowest among small caps (-2.23%).

Value was positive as investors sought more reasonably priced securities during the market’s pullback. Within the large cap universe, the return difference between the most attractively valued and least attractively valued stocks was 2.06%. The large cap Value spread was one standard deviation above average.

Size was a contributing factor in each index. The largest ten percent of companies outperformed the smallest ten percent, on average, within each capitalization range. The Size spread hovered near 1.0% within each universe.

Short-term momentum (STM) reversed. The stocks that had outperformed the most over the previous four weeks tended to underperform last week. STM declined the most in the Russell 2000 (-1.92%).

Medium-term momentum (MTM) was mildly positive and not a major influence. Stocks that had outperformed the most over the preceding six months slightly outperformed last week. MTM was highest in the Russell MidCap (+0.52%).

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.
