P4.25 Over the past 10 years, Molly O'Rourke has slowly built a diversified portfolio of common stock. Currently her portfolio includes 20 different common stock issues and has a total market value of $82,500. Molly is at present considering the addition of 50 shares of one of two common stock issues X or Y. To assess the return and risk of each of these issues, she has gathered dividend income and share price data for both over each of the last 10 years (2001-2010). Molly's investigation of the outlook for these issues suggests that each will, on average, tend to behave in the future just as it has in the past. She therefore believes that the expected return can be estimated by finding the average holding period return (HPR) over the past 10 years for each of the stocks. The historical dividend income and stock price data collected by Molly are given in the accompanying table.
