Dollar-cost averaging is an approach of investing a fixed amount regularly into a particular investment, regardless of unit price.
When the unit price is high, the same amount buys fewer units. When the unit price is low, the same amount buys more units. This investment approach averages out the costs of your units to achieve long-term asset appreciation.
Dollar-cost averaging is a prudent investment technique to “average out” the costs of your units over time to reduce the impact of short-term market fluctuations on investments.
In fact, as you make contributions to your MPF fund at regular intervals, you are effectively using dollar-cost averaging.
