10. February 26, 2007 Materials Created by Glenn Snyder – San Francisco State University 10 Systematic and Unsystematic Risk As more stocks are added, each new stock has a smaller risk-reducing impact  p falls very slowly after about 10 stocks are included, and after 40 stocks, there is little, if any, effect. The lower limit for  p is about 27% =  M   M = Market Risk  p = Portfolio Risk

14. February 26, 2007 Materials Created by Glenn Snyder – San Francisco State University 14 Market Risk Premium Market Risk Premium (RP M )  The additional return over the risk-free rate needed to compensate investors for assuming an average amount of risk  RP M = (R M – R F ) R M = market portfolio rate with ß = 1.0

February 26, 2007 Materials Created by Glenn Snyder – San Francisco State University 16 Sharpe and Treynor Ratios Treynor Ratio – calculates the average return over and above the risk-free rate of return per unit of the world market portfolio risk.  Treynor Ratio = (R i – R f ) /  i R i = Average return of the portfolio during period i R f = Average return of the risk-free rate during period i b i = The systematic (market) risk of the world market portfolio during period i
