In a ground-breaking article in the May, 1970 issue of the Journal of Finance, entitled "Efficient Capital Markets: A Review of Theory and Empirical Work," E. Fama proposed three types of efficiency: (i) strong-form; (ii) semi-strong form; and (iii) weak efficiency. He was a co-founder of Fama–French three-factor model (1993).

CFDR = (r m – r f )*(sigma p /sigma m – beta p ) sigma p /sigma m could be called the «degree of volatility» NB: sigma p /sigma m > beta p Analysis of abnormal return by E. Fama
