FYI: Eugene Fama, the de-facto originator of the Efficient Market Hypothesis, helped popularize the Fama-French three-factor model, which he developed alongside Finance professor Kenneth French in the 1990s. The three factors: size, value, and quality, were joined by a momentum component in the Carhart four-factor model. That model, developed in 1997, now serves as a reference point for a suite of new iShares smart-beta ETFs.
