Answer:
Step-by-step explanation:
a. Calculate the expected holding-period return and standard deviation of the holding- period return. All three scenarios are equally likely.
1/3 = 0.3333
Boom Holding Period Return - HPR
HPR = = (50 – 40 + 2)/40 = 0.3
Normal HPR=(43 – 40 + 1)/40 = 0.1
Recession HPR = (34 – 40 + 0.5)/40 = -0.1375
Expected Return =(0.3333*0.3)+(0.3333*0.1)+(0.3333*-0.1375)=0.1+0.0333-0.0458 = 0.0875
Var(r) = sd^2 = sum of p(s)[r(s)-E(r)]^2
Var(r) = (0.3333)[(0.3)-0.0875]^2 + (0.3333)[(0.1)-0.0875]^2 + (0.3333) +[-.1375-.0875]^2 =
Var(r)= 0.0151+ 0.0001 + 0.0169 = .0321
Sd(r)= sd square root = square root of 0.0321 = 0.1791
b. Calculate the expected return and standard deviation of a portfolio invested half in Business Adventures and half in Treasury bills. The return on bills is 4%.
Expected return = (0.5)(0.0875) + (0.5)(0.04) = 0.0438 + 0.02 = 0.0638
Sd = (0.5)(0.1791) = 0.0896
