Introduction to Dollar Cost Averaging
Dollar cost averaging (DCA) is a disciplined investment approach that helps mitigate market volatility and eliminates the need for market timing. By investing fixed amounts at regular intervals, you automatically purchase more shares when prices are low and fewer when prices are high. This systematic method smooths out your average purchase price over time.
How it works:
- Invest $100 monthly in a $50 stock → Buy 2 shares
- Price drops to $40 → Buy 2.5 shares with same $100
- Price rises to $60 → Buy 1.67 shares
- Result: Average cost of $46.67/share vs. initial $50
