What is Dollar Cost Averaging (DCA)?

Dollar cost averaging is an investment strategy where you invest a fixed amount at regular intervals, regardless of market conditions. This approach reduces the impact of volatility by buying more shares when prices are low and fewer when prices are high.

Formula:

Average Cost = Total Invested / Total Shares Purchased

DCA naturally results in a lower average cost per share than buying all at once at the high point.
