Stock C

Rate of Return (r )

Probability ( p )

The Economic Status

Optimistic

12 %

30 % or 0.30

Most Likely

9 %

50 % or 0.50

Pessimistic

-8%

10 % or 0.10

  1. Calculate the Expected Rate of Return E(r) for Stock C.
  1. Calculate Variance and Standard Deviation for Stock C.
  2. Calculate the Sharpe Ratio, assuming risk free rate is 4%.

It's ok tha t the probability is = 90

please make sure the answer is correct 100%

Solutions

Expert Solution

1) Expected rate of return on C

Economic Status Rate of return Probablity Expected return
Optimistic 12% 0.30 3.60
Most Likely 9% 0.50 4.50
Pessimistic -8% 0.10 -0.80
Total 7.30%

2) Variance and Standard Deviation

Economic Status Rate of return Probablity (Return - average)2

Probablity *

(Return - average)2

Optimistic 12% 0.30 22.09 6.627
Most Likely 9% 0.50 2.89 1.445
Pessimistic -8% 0.10 234.09 23.409
Total 31.481

Variance = [ Sum of Probablity * (Return - average)2 ]

              = 31.481 %2

Standard Deviation = [ Sum of Probablity * (Return - average)2 ]1/2

                            = [ 31.481 ]1/2

                            = 5.61% Answer

3) Sharpe ratio = [ ( Expected retun on security - Risk free rate ) / Standard deviation ]

                      = [ ( 7.3 - 4 ) / 5.61 ]

                      = 0.5882 Answer
