Investing Basics Know-How

Starting an Investment Program With Dollar Cost Averaging

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.

Bragging rights aside, there is good reason to determine your own portfolio’s performance: Measuring the performance of your total portfolio is useful to see if the long-term terminal value that you hope to achieve with your investment program is realistic.

In general, you should be examining the return on your portfolio to make sure it is within the target range you expected, based on the investment mix you have settled upon. If it isn’t, you may need to make some adjustments, switching out of underperforming (relative to peers) segments of your portfolio, or you may need to make changes in your future projections—for...
