Dollar-cost averaging is a systematic program of investing equal sums of money at regular intervals, regardless of the price of the investment. Investing by dollar-cost averaging means that you purchase number of shares when the share price is down. And you purchase number of shares when the price is up. Therefore, dollar-cost averaging allows you to purchase most of your investment shares at costs. Suppose that David is an investor using a dollar-cost averaging investment strategy. Each month David invests $900, regardless of the price of the investment at that particular time. The following table shows how a dollar-cost averaging strategy would affect David's investment in a fluctuating market, a declining market, and a rising market. For each market type, calculate the average share price and the average share cost based on the information given in the table.
