Combined Beta = 1

Combined return = 10%

Explanation:

given data

stock portfolio = $50,000

beta = 1.2

expected return = 10.8%

beta = 0.8

expected return = 9.2%

standard deviation = 25%

to find out

combination

solution

we get here first Combined Beta that is express as

Combined Beta = 1.2 * 50% + 0.8 * 50%

Combined Beta = 1

and

Combined return will be here

Combined return = 10.8 * 50% + 9.2 * 50%

Combined return = 10%
