Answers : -

a) Option b = 19.50 %

b) Option e = 10.20%

c) Option d = 0.003894

Explanations :-

a)

Expected Return of Portfolio
State of Economy Probability(P) Return(R)
      Expected Return(P × R)
Stock G 0.15 0.10 0.015
Stock J 0.65 0.20 0.13
Stock K 0.20 0.25 0.05
Expected Return = Total (P × R) 0.1950 (19.5%)

.

b)

expected return on an equally weighted portfolio
Probability(P) Return(R) of A Expected Return(P × R) of stock A Return(R) of B Expected Return(P × R) of stock B Return(R) of c P×R of stock C
Bhoom 0.64 0.09 0.0576 0.31 0.1984 0.05 0.032
Bust 0.36 0.05 0.018 0.05 0.018 - 0.05 -0.018
0.0756 0.2164 0.014

As per the question Return of stock are equally distributed between the 3 stock , so the probability of every stock return is

   = 1/3    = 0.333333 or 33.3333%

Stock Probability(P) Return(R) Expected Return(P × R
Stock A 0.3333 0.0756 0.02519748
Stock B 0.3333 0.2164 0.07213621
Stock C 0.3333 0.014 0.00466662

Expected return on an equally weigted portfolio ( Total (P ×R))

.

c)

calculate the expected returns for the portfolio in the boom and bust states.

  • ( 0.30 x 0.09) + ( 0.30 x 0.31) + (0.40 x 0.05) = 14%
  • (0.30 x 0.05) + (0.30 x 0.05) + (0.40 x -0.05) = 1%

calculate the total portfolio expected return  

(0.64 x 14%) + (0.36 x 1%) = 9.32%

calculate deviation of boom and bust portfolios expected return.

14% - 9.32% = 4.68%

1% - 9.32% = -8.32%

square the deviation of the boom and bust portfolios

4.68%2 = 0.00219024

-8.32%2 = 0.0069224

multiply each square deviation by its respective probabilitty

  • 0.00219024 x 0.64 = 0.0014017536
  • 0.0069224x 0.36 = 0.002492064

sum of products for variance

  • portfolio variance =0.0014017536 + 0.002492064= 0.0038938176 =0.003894
