What is Dollar-Cost Averaging?

Investing can be challenging. Even experienced investors who try to time the market to buy at the most opportune moments can come up short.

Dollar-cost averaging is a strategy that can make it easier to deal with uncertain markets by making purchases automatic. It also supports an investor's effort to invest regularly.

Dollar-cost averaging involves investing the same amount of money in a target security at regular intervals over a certain period of time, regardless of price. By using dollar-cost averaging, investors may lower their average cost per share and reduce the impact of volatility on the their portfolios.

In effect, this strategy eliminates the effort required to attempt to time the market to buy at the best prices.

Dollar-cost averaging is also known as the constant dollar plan.
