You own a stock portfolio invested 30 percent in Stock Q, 25 percent in Stock R, 25 percent in Stock S, and 20 percent in Stock T. The betas for these four stocks are .95, 1.12, 1.13, and 1.30, respectively. What is the portfolio beta? (Do not round intermediate calculations and round your answer to 2 decimal places, e. g., 32.16.)

Portfolio beta = 1.1075

Explanation:

The portfolio beta is a function of the weighted average of the individual stocks betas' that form up the portfolio. To calculate the portfolio beta, we use the following formula,

Portfolio beta = wA * Beta of A + wB * Beta of B + ... + wN * Beta of N

Where,

Portfolio beta = 0.30 * 0.95  +  0.25 * 1.12  +  0.25 * 1.13  +  0.20 * 1.30

Portfolio beta = 1.1075
