You are expecting either a recession or steady growth next year. Recession has a 33% probability of happening. In steady growth, stock ABC returns 11.00% and stock XYZ returns 8.00%. In a recession, stock ABC returns -5.80% and stock XYZ returns -3.60%. You are going to put together a portfolio of these two stocks with positive portfolio weight in each and allocate 47% of the portfolio to ABC with the remainder to XYZ.

Stock ABC :

State of Economy Probability (P) Return (x) Px x - sum of Px (x - sum of Px)^2 P*(x - sum of Px)^2
Steady Growth 0.67 11 7.37 5.544 30.735936 20.59307712
Recession 0.33 -5.8 -1.914 -11.256 126.697536 41.81018688
Mean 5.456 Variance 62.403264

Stock XYZ :

State of Economy Probability (P) Return (y) Py y - sum of Py (y - sum of Py)^2 P*(y - sum of Py)^2
Steady Growth 0.67 8 5.36 3.828 14.653584 9.81790128
Recession 0.33 -3.6 -1.188 -7.772 60.403984 19.93331472
Mean 4.172 Variance 29.751216
State of Economy Probability (P) x - sum of Px y - sum of Py P*(x - sum of Px * )(y - sum of Py)
Steady Growth 0.67 5.544 3.828 14.21902944
Recession 0.33 -11.256 -7.772 28.86893856
Covariance between ABC & XYZ 43.087968

Variance of the portfolio = weight of ABC^2*Variance of ABC + Weight of XYZ^2*Variance of XYZ + 2 * Weight of ABC * Weight of XYZ * Covariance between ABC and XYZ

= 0.47^2 * 62.40 + 0.53^2* 29.75 + 2 * 0.47*0.53*43.09

= 13.78 + 8.36 + 21.47 = 43.61
