Answer:
CCC's new required return be 16.5%
Explanation:
For computing the new required return, first, we have to compute the risk-free rate of return which is shown below:
Expected return = Risk- free rate of return + Beta × (Market risk - Risk- free rate of return)
12% = Risk- free rate of return + 1.5 × (10% - Risk- free rate of return))
12% = Risk- free rate of return + 15% - 1.5% Risk- free rate of return
So, the Risk- free rate of return is 6%
Now the average stock is increased by 30%
So, the new market risk is 13% and other things will remain constant
So, the new required return equal to
= 6% + 1.5 × (13% - 6%)
= 6% + 1.5 × 7
= 16.5%
