Need assistance with part B

Consider the following table:

   

Stock Fund Bond Fund
Scenario Probability Rate of Return Rate of Return
Severe recession 0.05 −27% −12%
Mild recession 0.25 −7% 18%
Normal growth 0.40 12% 11%
Boom 0.30 17% −8%

a. Calculate the values of mean return and variance for the stock fund. (Do not round intermediate calculations. Round "Mean return" value to 1 decimal place and "Variance" to 2 decimal places.)  

Mean return 6.80 %
Variance 146.76 %-Squared

b. Calculate the value of the covariance between the stock and bond funds. (Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places.)

Covariance ________ %-Squared

Solutions

Expert Solution

Covariance between two assets, X and Y can be calculated as:

where rXi is the return for asset X, rYi is the return for asset Y

ERPx and ERPy are the expected returns (mean returns) for X and Y

pi is the probability for a given state i, and

N is the number of states.

Scenario Probability (p) Rate of Return (rs) Rate of Return (rb) rs-E(rs) rb-E(rb) (rs-E(rs))^2 (rs-E(rs))(rb-E(rb)) p*(rs-E(rs))(rb-E(rb))
Severe recession 0.05 -27% -12%         -0.3380         -0.1790            0.1142440           0.06050                 0.0030251
Mild recession 0.25 -7% 18%         -0.1380           0.1210            0.0190440         -0.01670               -0.0041745
Normal growth 0.40 12% 11%           0.0520           0.0510            0.0027040           0.00265                 0.0010608
Boom 0.30 17% -8%           0.1020         -0.1390            0.0104040         -0.01418               -0.0042534
Expected return 6.80% 5.90% Covariance               -0.0043420

Covariance = -43.42 %-Squared
