Answer:
The expected return of your portfolio = 12.42%
Explanation:
At first we have to determine the weight for each of the stock by multiplying number of shares by stock price.
W = 525 x $43 = $22,575
X = 780 x $29 = $22,620
Y = 435 x $94 = $40,890
Z = 680 x $51 = $34,680
Total = $120,765
Stock Capital Weight(W) Expected Return(R) W x R
W $22,575 (22,575/120,765)=0.1869 10 1.8693
X $22,620 (22,620/120,765)=0.1873 15 2.8095
Y $40,890 (40,890/120,765)=0.3386 11 3.7246
Z $34,680 (34,680/120,765)=0.2872 14 4.0208
= 12.42%
