* Eugene Fama E. Fama is most often thought of as the father of efficient market hypothesis (EMH), beginning with his Ph.D. thesis. 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: strong-form; semi-strong form; and weak efficiency. He was a co-founder of Fama–French three-factor model (1993). © A. Zaporozhetz, WIUU, Spring 2013

* GSS, Gross security selection = ract - rCAPM = CFDR + NSS CFDR, Compensation for diversifiable risk is the effect of higher volatility of portfolio on the GSS. CFDR = (rm – rf)*(sigmap/sigmam – betap) sigmap/sigmam could be called the «degree of volatility» NB: sigmap/sigmam > betap Analysis of abnormal return by E. Fama © A. Zaporozhetz, WIUU, Spring 2013

* NSS, Net security selection = GSS – CFDR NSS is the effect of “smart” selection of securities for a portfolio, and effective & efficient trading (opening/closing positions). © A. Zaporozhetz, WIUU, Spring 2013

* In 2012, a managed portfolio: mean returnp = 0,41% betap = 0,77 sigmap = 3,55% Market proxy is ACWIFM (0,24%;1,83%) Find: GSS Degree of volatility CFDR NSS Evaluate the portfolio manager’s performance Practice © A. Zaporozhetz, WIUU, Spring 2013

* Analysis of abnormal return by E. Fama If NSS > 0, the portfolio manager was effective: he/she “added up” to the portfolio return. If NSS < 0, the portfolio manager was not effective: he/she “ate up” some return. © A. Zaporozhetz, WIUU, Spring 2013
