Explanation / Answer

1) Probability of Boom = 0.65

Return in case of boom = 10%

Probability of Recession = 0.35

Return in case of Recession = 3%

Expected Return = = xp

     = Probability of Boom * Return in case of boom + Probability of Recession * Return in case of Recession

     = 0.65 * 10% + 0.35 * 3% = 7.55%

Vairance = Var(X) = x2p 2 = 0.65* (0.1 - 0.0755)2 + 0.35* (0.03 - 0.0755)2 = 0.001115

2)

Portfolio Beta is the weighted average of the betas of individual securities.

   = 1.74 * 26.19% + 1.85 * 30.95% + 1 * 42.86% = 1.457

Stock Amount Invested Security Beta Weightage A $5,500 1.74 26.19% B $6,500 1.85 30.95% C $9,000 1 42.86% TOTAL $21,000 100.00%
