c.12.8%
d.14.6%
Group of answer choices
The expected return is computed as shown below:
= Return of Stock A x Weight of Stock A + Return of Stock B x Weight of Stock B
Return of Stock A is computed as follows:
= Prob. of Boom Economy x return of Stock A in Boom Economy + Prob. of Normal Economy x return of Stock A in Normal Economy + Prob. of Slow Down Economy x return of Stock A in Slow Down Economy + Prob. of Recession Economy x return of Stock A in Recession Economy
= 0.20 x 0.40 + 0.40 x 0.25 + 0.30 x 0.00 + 0.10 x - 0.20
= 0.08 + 0.10 + 0 - 0.02
= 16% or 0.16
Return of Stock B is computed as follows:
= Prob. of Boom Economy x return of Stock B in Boom Economy + Prob. of Normal Economy x return of Stock B in Normal Economy + Prob. of Slow Down Economy x return of Stock B in Slow Down Economy + Prob. of Recession Economy x return of Stock B in Recession Economy
= 0.20 x 0.28 + 0.40 x 0.12 + 0.30 x 0.07 + 0.10 x 0.00
= 0.056 + 0.048 + 0.021 + 0
= 12.5% or 0.125
So, the expected return is computed as follows:
= 0.16 x [ $ 1,200,000 / ($ 1,200,000 + $ 800,000) ] + 0.125 x [ $ 800,000 / ($ 1,200,000 + $ 800,000) ]
= 0.16 x [$ 1,200,000 / $ 2,000,000] + 0.125 x [$ 800,000 / $ 2,000,000]
= 0.096 + 0.05
= 14.6%
So, the correct answer is option d.
