The Boring Trick That Beats Market Timing
🛒 Some people spend all year trying to guess the exact day to buy. Some people put in $100 every Monday and don't look. The second group tends to win — not because they're smarter, but because they've stopped trying to be.
💡 Key idea
Invest the same amount on the same day every month and ignore the price. That is the entire strategy.
🧠 Why it matters
Dollar-cost averaging (DCA) means investing the same fixed amount on a set schedule — say $300 on the 1st of every month — no matter what the price is doing. When prices are low your money buys more shares; when they are high it buys fewer. Over time your average cost smooths out and you never have to guess the right moment.
🌍 In the real world
📉 Two people each had $12,000 in early 2008. One waited for the bottom to invest it all at once — and got so spooked by the crash they never pulled the trigger. The other just put in $1,000 a month, automatically, straight through the crash, buying their cheapest shares at the scariest moment. A decade later the DCA investor was far ahead — not because they were smart, but because they were boring and consistent.
📌 Takeaways
- Same amount, same day, every month — automate it
- Low prices mean your money buys more shares (a feature, not a bug)
- Removing the timing decision removes the emotion that wrecks returns
