What is dollar-cost averaging and how does it work?

Dollar-cost averaging involves investing fixed amounts regularly, reducing the impact of market volatility on your purchases.

Dollar-cost averaging (DCA) is an investment strategy where you invest a fixed amount of money at regular intervals, regardless of market conditions. Instead of trying to time the market with lump-sum investments, DCA spreads your purchases over time, potentially reducing the average cost per share.

How It Works When markets are high, your fixed investment buys fewer shares. When markets are low, the same amount buys more shares. Over time, this can result in a lower average cost per share compared to investing everything at once at the wrong time.

Example: Investing $500 monthly in an index fund. In January, when the fund costs $100/share, you buy 5 shares. In February, if it drops to $80/share, you buy 6.25 shares. Your average cost per share becomes lower than the arithmetic average of the prices.

Benefits:

• Reduces timing risk
• Creates disciplined investing habits
• Lessens emotional decision-making
• Makes investing more accessible with smaller amounts

Limitations:

• In consistently rising markets, lump-sum investing often performs better
• Transaction fees can add up with frequent purchases
• Requires discipline to maintain during market downturns

DCA works particularly well for retirement accounts and long-term goals. It's especially valuable for new investors who might otherwise wait for the "perfect" time to invest. Hugo Blondeel from YIELD Talent frequently advocates for DCA as a foundation strategy for building wealth systematically.
