You have $10636 to invest in a stock portfolio. Your choices are Stock X with an expected return of 13.35 percent and Stock Y with an expected return of 10.69 percent. If your goal is to create a portfolio with an expected return of 11.81 percent, how much money (in $) will you invest in Stock X? Answer to two decimals, carry intermediate calcs. to four decimals.
Expected return of portfolio = (W1 x r1) + (W2 x r2) +…. (Wn x rn)
W 1, W2… W n = Weight of stock 1, 2 … n etc.
r 1, r 2… r n = Return of stock 1, 2 … n etc.
Suppose weight of stock X is WX and that of stock Y is WY
WX + W y = 1
W y = 1 - WX
Expected return of portfolio = (WX x rX) + (WY x rY)
11.81 % = (WX x 13.35 %) + (WY x 10.69 %)
0.1181 = (WX x 0.1335) + (WY x 0.1069)
0.1181 = (WX x 0.1335) + [(1-WX) x 0.1069]
0.1181 = 0.1335 WX - 0.1069 WX + 0.1069
0.1181 = 0.0266 WX + 0.1069
0.0266 WX = 0.1181 - 0.1069
0.0266 WX = 0.0112
WX = 0.0112/0.0266 = 0.421052631578947 or 0.4211
Amount to invest in stock X = 0.4211 x $ 10,636 =$ 4,478.8196 or $ 4,478.82
$ 4,478.82 needs to invest in stock X.
