Dollar-Cost Averaging: What It Is and Why It Matters
Dollar-cost averaging (DCA) is an investment strategy where you invest a fixed amount of money at regular intervals — weekly, fortnightly, or monthly — regardless of the current price, automatically buying more when prices are low and less when prices are high.
The primary advantage of DCA is that it removes the emotional paralysis of market timing. Instead of agonising over whether now is a good time to invest, you invest the same amount every period and let consistency do the work.
How DCA smooths volatility: if you invest $500/month and the market drops 20%, your next $500 buys 25% more shares at the lower price. When the market eventually recovers, those extra shares amplify your returns. Over time, your average cost per share tends to be lower than the average market price.
Research consistently shows that for most investors, DCA combined with staying invested long-term produces better outcomes than attempting to time market peaks and troughs — a task that consistently defeats even professional fund managers.
DCA is particularly powerful during bear markets, when regular investing buys more shares at depressed prices — positioning you for outsized returns during the recovery.
Implementation is simple: set up automatic recurring investments through your brokerage or fund provider, choose your amount and frequency, and let it run. Review annually rather than reactively.
