Regular Investing: The Power of Dollar-Cost Averaging

Adding regular contributions to your investment is a form of dollar-cost averaging (DCA) — a strategy where you invest a fixed amount at regular intervals regardless of market conditions. This approach removes the pressure of trying to time the market and takes advantage of price volatility by naturally buying more units when prices drop.

Historical data shows that for most investors, consistent DCA into broad market index funds outperforms attempting to time market entry points. The key is choosing a contribution frequency that matches your cash flow and minimizes transaction costs.
