Total Amount invested in the portfolio = $86000
Stock O
Amount invested in stock P = $17800
Weight of stock O in the portfolio = WO = Amount invested in stock O/Amount invested in the portfolio = 17800/86000 = 0.206976744186047
Expected return on stock O = E[RO] = 15.5%
Stock P
Amount invested in stock P = $25600
Weight of stock P in the portfolio = WP = Amount invested in stock P/Amount invested in the portfolio = 25600/86000 = 0.297674418604651
Expected return on stock P = E[RP] = 12%
Stock Q
Amount invested in stock Q = $8600 - $17800 - $25600 = 42600
Weight of stock Q in the portfolio = WQ = Amount invested in stock Q/Amount invested in the portfolio = 25600/86000 = 0.495348837209302
Expected return on stock Q = E[RP]
Portfolio
Expected return of the portfolio = E[RP] = 11.2%
Expected return of the portfolio is calculate using the formula:
Expected return of Portfolio = E[RP] = WO*E[RO] + WP*E[RP] + WQ*E[RQ]
11.2% = 0.206976744186047*15.5% + 0.297674418604651*12% + 0.495348837209302*E[RQ]
11.2% = 0.0320813953488372 + 0.0357209302325581 + 0.495348837209302*E[RQ]
11.2% = 0.0678023255813954 + 0.495348837209302*E[RQ]
0.495348837209302*E[RQ] = 0.0441976744186046
E[RQ] = 0.0441976744186046/0.495348837209302 = 8.9225352112676% ~ 8.92% (Rounded to two decimals)
Expected return on stock Q = E[RQ] = 8.92%
Answer -> 8.92%
