Suppose you invest $100,000 and buy 200 shares of Apple at $200 per share ($40,000) and 1000 shares of Coca-Cola at $60 per share ($60,000). If Apple’s stock rises to $240 per share and Coca-Cola stock falls to $57 per share and neither paid dividends, what is the new value of the portfolio? What return did the portfolio earn? Show that Eq. 12.2 is true by calculating the individual returns of the stocks and multiplying them by their weights in the portfolio. If you don’t buy or sell any shares after the price change, what are the new portfolio weights?
