Quick Answer
Dollar-cost averaging invests a fixed amount at regular intervals regardless of short-term market movements. It can reduce timing pressure and build discipline, but it cannot guarantee profit, prevent losses or outperform lump-sum investing. Outcomes still depend on asset returns, fees, horizon and execution.
Correct Interpretation and Practical Use
Core Explanation
A fixed amount buys more units when prices are lower and fewer when prices are higher. That is a mathematical mechanism, not a promise of recovery. DCA can lose money if the asset declines, fees are excessive or contributions stop. When cash is already available, phasing it in also creates an opportunity cost while cash waits.
How to Use This
- Confirm the asset is suitable instead of using DCA to justify a poor product.
- Calculate sales, platform and annual fund costs.
- Set the amount, frequency, horizon and review conditions.
