Answer:
0.67
Explanation:
Beta measures the systemic risk of a portfolio
The portfolio's beta can be determined by adding together the weighted beta of each stock in the portfolio
weighed beta of a stock = percentage of the stock in the portfolio x beta of the stock
total number of stocks in the portfolio 400 + 290 + 700 = 1390
(400 / 1390 x 0.6) + (290 / 1390 x 1.2) + (700 / 1390 x 0.5) =
0.17 + 0.25 + 0.25 = 0.67
