Consider the two (excess return) index-model regression results for stocks a and b. the risk-free rate over the period was 6%, and the market’s average return was 14%. performance is measured using an index model regression on excess returns. stock a stock b index model regression estimates 1% + 1.2(rm − rf) 2% + 0.8(rm − rf) r-square 0.576 0.436 residual standard deviation, σ(e) 10.3% 19.1% standard deviation of excess returns 21.6% 24.9% a. calculate the following statistics for each stock: (round your answers to 4 decimal places.)

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
