Answer:
19.952%
Step-by-step explanation:
For computing the expected rate of return, first we have to determine the beta which is shown below:
= Stock Auto desk weightage × stock Auto desk beta + Stock Costco weightage × stock Costco beta
= 0.70 × 2.20+ 0.30 × 0.68
= 1.54 + 0.204
= 1.744
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below
Expected rate of return = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return)
= 6% + 1.744 × (14% - 6%)
= 6% + 1.744 × 8%
= 6% + 13.952%
= 19.952%
