The first step is always the hardest. And individual investors taking their first steps in an investment program must also confront a sea of stock market uncertainty. Some plunge headlong into the market with all their savings. Others barely wet their feet before heading back to the safe shores of their money market funds. The problem, however, with these two all-or-nothing approaches is one of timing—the risk of entering the market at a high point in the market cycle.
Dollar cost averaging is simple in concept: Invest a fixed amount at equal intervals and continue to do so over a long period. The result is that more shares of a stock or mutual fund are purchased when prices are relatively low and less are purchased when prices are relatively high. This can result in lower average per share cost over time.
