Swarn bought 200 shares of a stock for $36 per share. He paid $245 in trading commissions. He has received dividends in the amounts of $98, $156, and $300 over the last three years, respectively. Assuming that Swarn is in the 15% marginal tax bracket for capital gains and dividends, what is his holding-period return if he sells all of the shares at $40 each with a $245 trading commission? What is Swarn's tax-adjusted holding period rate of return?
