Share | Stock Return/Purchase Date Calculator The returns (profits and losses) for buy-and-hold investors have been on a roller coaster ride since prices peaked in 2000 and 2007. To see how buy-and-hold investing has performed during this and other investing periods, use the Stock Return/Purchase Date Calculator. The calculator displays a chart of percent returns for a selected period for a given stock highlighting the profitable investment dates in green and the unprofitable ones in red. The chart shows the percent return of each buy-and-hold investment for a period of purchase dates that you specify on the input form below. The percent return for each purchase date is computed using the following formula: Percent return = ((Today's closing price - Purchase date closing price) / Purchase date closing price) * 100 The calculator assumes that the stock has been held since the purchase date so the percent return is valued as of today's closing price. All prices are from Yahoo! Finance. Stock Return/Purchase Calculator To avoid slow computations, use Weekly or Monthly prices for durations >= 10 years.
