Answer:
beta of stock B = 1.33
Explanation:
the beta of treasury bills is 0
the beta of stock A = 1.46
the beta of stock B = ?
the portfolio contains equal amounts of each investment and its overall beta is 0.93
0.93 = (0 x 1/3) + (1.46 x 1/3) + (B x 1/3)
0.93 = 0 + 0.4867 + 0.333B
0.93 = 0.4867 + 0.333B
0.4433 = 0.333B
B = 0.4433 / 0.333 = 1.33
