Sam Sharp purchased 100 shares of Electric Lighting Inc. (ELI) one year ago for $60 per share. He also received cash dividends totaling $5 per share over the past twelve months. Now that ELI’s stock price has increased to $64.50 per share, Sam has decided to sell his holdings. What is Sam’s gross (pre-tax) and net (after-tax) return on this investment, assuming that he faces a 15% tax rate on dividends and capital gains?
