Dollar Cost Averaging: What is It?
Instead of investing assets all together in a lump sum, the investor works their way into a position by slowly buying smaller amounts over a longer period of time. This spreads the cost basis out over several years, providing insulation against changes in market price.
So how do you set up your own dollar cost averaging plan?
In order to begin a dollar cost averaging plan, you must do a couple things:
- Decide exactly how much money you can invest each month or period.
- Make certain that you are financially capable of keeping the amount consistent; otherwise the plan will not be as effective.
- Select an investment that you want to hold for the long term, preferably five to ten years or longer.
- At regular intervals (weekly, monthly or quarterly works best), invest that money into the investment you’ve chosen. If your broker offers it, set up an automatic withdrawal plan so the process becomes automated.
Here are the numbers. Let's say the mutual fund share price is $50/share to start.
Purchase 1 - $100, 2 shares at $50 each
Purchase 2 - $100, 1.96 shares at $51 each (can only buy 1.96 shares b/c price has appreciated)
Purchase 3 - $100, 1.92 shares at $52 each
Purchase 4 - $100, 1.88 shares at $53 each
In this case, you would now have $400 invested in this mutual fund and you would own just under 8 shares (7.76 shares to be exact). The average price paid would be $51.50. Therefore if the mutual fund goes below that you are at a loss but if it is above that then you have gains.
Dollar cost averaging works even better when a fund decreases in value after you buy it. For instance, you buy 1000 shares of a stock at $50. It goes down to $25 and you buy another 1000 shares. At that point, you would own 2000 shares at $37.50. This helps b/c then the stock doesn't have to make it all the way back to $50 for you to break even, it only has to get to $37.50. Obviously it is useful if you believe in the prospects of a stock. If you bought a stock that has been downgraded or isn't attractive anymore, then you may just want to cut your loses.
Godspeed.
