4 © A. Zaporozhetz, WIUU, Spring GSS, Gross security selection = r act - r CAPM = CFDR + NSS CFDR, Compensation for diversifiable risk is the effect of higher volatility of portfolio on the GSS. 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

5 © A. Zaporozhetz, WIUU, Spring 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).

6 © A. Zaporozhetz, WIUU, Spring In 2012, a managed portfolio: mean return p = 0,41% beta p = 0,77 sigma p = 3,55% Market proxy is ACWIFM (0,24%;1,83%) Find: GSS Degree of volatility CFDR NSS Evaluate the portfolio managers performance Practice

7 © A. Zaporozhetz, WIUU, Spring 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.
