Recently, the Mutual Fund Site presented a post about the easiest and smartest investment strategy: investing regularly on an automated contribution plan. This investment strategy is also (or better) known as Dollar Cost Averaging and makes perfect sense when used with mutual funds, whether more-volatile funds that invest in small cap stocks, index funds, or even bond funds.

Aside from buying more units when the markets are down (and less units when the market is up), Dollar Cost Averaging strips the issue of “market timing” out of your investment strategy. This can be fairly important because virtually nobody can “time” the market with absolute accuracy. That means only luck and no amount of research can help an investor buy at the absolute lowest.

Likewise, even the unluckiest investor will have difficulty buying at the absolute highest, but we often feel that way – that we bought at the highest and now our investments are doomed to fail.

This is where Dollar Cost Averaging makes great sense. Not only because it takes the “guess” work and “luck” out of the situation, but because historically it errs on the up-side. That means that if you use dollar cost averaging, your returns are more likely going to resemble the returns of someone who has the great luck and skill to buy at the absolutely lowest days.

This may seem strange because one would think that, statistically, you are more likely to buy the “average” or median between the best and worst possible days to invest. This would be true in a flat market, but historically markets have risen. Therefore, in a 10-year rolling average, even the “worst” possible day will be the best day at some point.

In fact, a Canadian Financial institution actually ran these numbers based on their market, the S&P TSX index. In their illustration, if you were to invest at the absolute worst days over the period of 1989 through to 2009, your returns would still be positive at 5.42% annually. The absolute best days: 7.36%.

And by employing a Dollar Cost Averaging strategy and invested each month on the first business day of the month, your return would have been 6.38%, less than 1% lower than if you had invested at the absolute best time possible for the year but nearly 2% better than if you had invested on the absolute worst days.

Interesting that a simple, more-affordable strategy could yield such positive results. But again, when you look at the historically rising market, it makes sense. In a declining market, the rates above would probably be reversed, but ultimately, investing through an automated investment program (dollar cost averaging) allows you the benefits of not having to worry about the impossibility of market timing, especially when it comes those riskier mutual funds, like those investing in small cap stocks. The investment strategy, however, can be used with other types of investments as well, even those in declining market-value environment such as bond funds.

Give it some thought….
