Computation Procedures

All prices are from Quandl and have been adjusted for splits and dividends. Adjusted prices values are lower than unadjusted prices.

All computations are based on monthly closing adjusted prices.

The number of shares purchased for each recurring investment is based on the monthly close of the specified stock and the amount of the recurring investment. For example, a $1,000 investment at $20 per share would buy 50 shares for that month. The number shares purchased for each recurring investment are summed to give the total number of shares purchased at the end of the investment period.

Final value of all shares is the number of initial shares plus the total number of shares purchased from all recurring investments during the dollar-cost-averaging period multiplied by the closing price of the last date.
