An
investment strategy in which one makes
investments in the same dollar amount at regular times. For example, one may
buy $1,000 in
Stock A every month, regardless of Stock A's current
price. Because this means one buys fewer shares when the
price is high and more when the price is low, dollar-cost averaging aims to reduce the average
cost of the
shares one buys. This increases the
profit per share when one
sells the stock. Dollar cost averaging is most common with shares of a
mutual fund or a
retirement plan. It is also called a constant dollar plan.
