Expert Solution

No. of Shares Share Price Expected Return
Apple Computer 600 537 12%
Cisco System 10000 24 10%
Colgate Palmolive 5000 93 8%

(a) The above data is provided. We will first calculate the total value of od individual stocks in the portfolio.

Value of stock = No. of shares*Share Price

Value of Apple computer shares = 600*537 = 322200

Value of Cisco Systems shares = 10000*24 = 240000

Value of Colgate-Palmolive shares = 5000*93 = 465000

Total value of the portfolio = Value of Apple computer shares + Value of Cisco Systems shares + Value of Colgate-Palmolive shares = 322200+240000+465000 = 1027200

Weight of Apple computers =WA = Value of Apple computer shares/Total value of the portfolio = 322200/1027200 = 0.3137 = 31.37%

Weight of Cisco Systems =WC = Value of Cisco shares/Total value of the portfolio = 240000/1027200 = 0.2336 = 23.36%

Weight of Colgate-Palmolive =WCP = Value of Colgate-Palmolive shares/Total value of the portfolio =465000/1027200 = 0.4527 = 45.27%

Weight of Apple computers =WA = 31.37%, Weight of Cisco Systems =WC = 23.36%, Weight of Colgate-Palmolive =WCP = 45.27%

(b) Expected Return on Apple Computers = E[RA] = 12%, Expected Return on Cisco Systems = E[RC] = 10%, Expected Return on Colgate-Palmolive = E[RCP] = 8%

Expected Return of the portfolio is calculated using the formula:

E[Rp] = E[RA]*WA + E[RC]*WC + E[RCP]*WCP​​​​​​​ = 12%*31.37% + 10%*23.36% + 8%*45.27% = 9.72%

Expected return of the portfolio = 9.72%

(c) Apple stock goes up by $ 24​, Cisco rises by $ 4​, and​ Colgate-Palmolive falls by $ 13

New share price of Apple = 537+24 = 561

New share price of Cisco = 24+4 = 28

New share price of Colgate-palmolive = 93-13 = 80

Value of Apple computer shares = 600*561 = 336600

Value of Cisco Systems shares = 10000*28 = 280000

Value of Colgate-Palmolive shares = 5000*80 = 400000

Total value of the portfolio = Value of Apple computer shares + Value of Cisco Systems shares + Value of Colgate-Palmolive shares = 336600+280000+400000 = 1016600

Weight of Apple computers =WA = Value of Apple computer shares/Total value of the portfolio = 336600/1016600 = 0.3311 = 33.11%

Weight of Cisco Systems =WC = Value of Cisco shares/Total value of the portfolio = 280000/1016600 = 0.2754 = 27.54%

Weight of Colgate-Palmolive =WCP = Value of Colgate-Palmolive shares/Total value of the portfolio =400000/1016600 = 0.3935 = 39.35%

No. of Shares New Share Price Expected Return New value Weights
Apple Computer 600 561 12% 336600 33.11%
Cisco System 10000 28 10% 280000 27.54%
Colgate Palmolive 5000 80 8% 400000 39.35%

New weight of Apple computers =WA = 33.11%, New weight of Cisco Systems =WC = 27.54%, New weight of Colgate-Palmolive =WCP = 39.35%

(d) Expected Return on Apple Computers = E[RA] = 12%, Expected Return on Cisco Systems = E[RC] = 10%, Expected Return on Colgate-Palmolive = E[RCP] = 8%

Expected Return of the portfolio is calculated using the formula:

E[Rp] = E[RA]*WA + E[RC]*WC​​​​​​​ + E[RCP]*WCP​​​​​​​ = 12%*33.11% + 10%*27.54% + 8%*39.35% = 9.88%

Expected Return of the portfolio at new prices = 9.88%
