A lot! Profitability subsumes all of “quality” investing, explaining both the performance of the strategies that industry markets and the factors that academics employ. It also has striking power pricing “defensive equity” strategies that overweight low-beta or low-volatility stocks. Profitability tilts explain all the abnormal performance of popular “alternative value” strategies, including those adjusted for “intangibles,” and half of value's post-2007 underperformance. Profitability is crucial for pricing a wide array of seemingly unrelated anomalies, yielding a more parsimonious understanding of the cross section of expected returns.
