Suppose your expectations regarding the stock price are as follows: State of the Market Probability Ending Price HPR (including dividends) Boom 0.23 $ 140 52.0 % Normal growth 0.24 110 19.0 Recession 0.53 80 11.5 Use the equations E(r)=sp(s)r(s) E ( r ) = s p ( s ) r ( s ) and 2=sp(s)[r(s)E(r)]2 2 = s p ( s ) [ r ( s ) E ( r ) ] 2 to compute the mean and standard deviation of the HPR on stocks
