I spoke to a number of boomers recently who were contemplating investing in bank or credit union Certificates of Deposit (CDs) because they were not comfortable with market volatility. They were asking about Dollar Cost Averaging versus Lump Sum Investing so I thought it was time to revisit the concept.
Dollar Cost Averaging, or DCA, (let’s face it, in this business everything has to be alphabet soup) is a strategy where you systematically invest a fixed dollar amount at regular intervals i.e. monthly or quarterly. It works best as a long-term strategy since the idea is that by systematically investing you are buying more shares when the market is down and fewer shares when the market is up thereby reducing the average share price that you pay for the security.
DCA isn’t designed to protect you from a loss in a declining market (although it can as we will discuss later) and it doesn’t guarantee a gain but it does eliminate the stress of deciding when to invest so you do away with “market timing”. It’s a disciplined strategy so make sure you have a longer term goal and the resources to maintain the strategy through the highs and lows.
You may not realize it but if you are investing through a retirement IRA or 401k you are in effect using a DCA strategy since money is coming out of your check each pay period and automatically invested in your 401k or IRA. Here’s a graph showing how the average share price is lowered using a DCA strategy courtesy of Forefield, Inc.:
Often the question comes up, “which is better, DCA or Lump Sum investing?” The answer isn’t that simple. Lump Sum investing depends on the timing of the investment.
If you enjoy following the market and consider yourself an experienced investor then you may feel confident timing the buying and selling of your investments and you may be able to outperform a DCA strategy. As we know, the markets are not predictable and many investors fall prey to the “buy high and sell low” trap. As a result their losses may be more severe than the DCA investor who is buying smaller amounts when the market is at a high.
Since a DCA investor is buying more shares of a security as the price declines there is some downside protection in a declining market. As the market rebounds the DCA investor will “break even” faster than their Lump Sum investor because the DCA investor owns more shares at a lower average price than the Lump Sum investor who invested before the market started declining.
Which makes the most sense for you? Among other factors it depends on what you goal is and how long you have to invest. It also depends on your risk tolerance and comfort level with investing in the market. You can get more information of how to find your risk tolerance here.
Keep in mind that it’s not an all of nothing proposition. DCA might make sense for part of your portfolio while investing with a lump sum may be suitable for another part of your portfolio. In either event the key is to stay invested and avoid jumping in and out of the market.
