Answer:
Portfolio beta = 1.1075
Step-by-step 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,
- w represents the weight of each stock in portfolio
Portfolio beta = 0.30 * 0.95 + 0.25 * 1.12 + 0.25 * 1.13 + 0.20 * 1.30
Portfolio beta = 1.1075
