Weight of stock A= $250,000 / $1,000,000
= 0.25
Weight of stock B= $100,000 / $1,000,000
= 0.10
Weight of stock C= $300,000 / $1,000,000
= 0.30
Weight of stock D= $350,000 / $1,000,000
= 0.35
Portfolio beta = 0.25*1.25 + 0.10*1.60 + 0.30*0.80 + 0.35*-0.20
= 0.3125 + 1.16 + 0.24 - 0.07
= 1.6425
The required return of the portfolio is calculated using the Capital Asset Pricing Model (CAPM)
The formula is given below:
Ke= Rf+b[E(Rm)-Rf]
where:
Rf= risk-free rate of return
Rm= expected rate of return on the market.
Rm-Rf= Market risk premium
b= Stock’s beta
Ke= 4% + 1.6425*(11% - 4%)
= 4% + 11.4975%
= 15.4975% 15.50%.
