Suppose your expectations regarding the stock price are as follows: hpr (including dividends) ending price $140 110 80 state of the market probability 0.35 0.30 0.35 boom normal growth recession 44.5% 14.0 -16.5 use equations 5.11 and 5.12 to compute the mean and standard deviation of the hpr on stocks. derive the probability distribution of the 1-year hpr on a 30-year u. s. treasury bond with an 8% coupon if it is currently selling at par and the probability distribution of its yield to maturity a year from now is as follows
