Dollar-Cost Averaging: The Boring Strategy That Works
Published 3 August 2026
Dollar-cost averaging means buying a fixed amount on a fixed schedule, regardless of price. It is unglamorous, requires no skill, and outperforms most people who try to be clever.
How it works
$50 every Friday. Price high, you get less. Price low, you get more. You automatically buy more when things are cheap and less when expensive โ the opposite of what emotion produces.
Why it beats timing
Timing the market requires being right twice: when to buy and when to sell. Most professionals cannot do this reliably. Someone checking prices between other commitments certainly cannot.
More importantly, DCA removes the decision. No deciding whether today is the day. No watching a dip and wondering if it will fall further. The decision was made once; everything after is execution.
What it protects you from
Mostly yourself. The two ways people lose money are buying tops out of excitement and selling bottoms out of fear. DCA does neither, because it does not consult your feelings.
It also removes the worst outcome: putting everything in on one day that turns out to be a peak.
Being honest about the limits
DCA is not magic. In a market that only falls, you lose money more slowly than a lump sum, but you still lose. It does not make a bad asset good.
And historically, in markets that mostly rise, lump-sum investing beats DCA on average โ because time in the market matters. DCA wins on behaviour, not arithmetic. It is the strategy you can actually stick to.
Doing it properly
- Pick an amount you will not need. Selling early because rent is due destroys the whole point.
- Pick a schedule and automate it. Weekly or monthly. Manual means you will eventually skip during a crash โ exactly when you should not.
- Stick to established assets. DCA into something that goes to zero simply arrives at zero on a schedule.
- Think in years. Judging it after two months is judging the weather, not the climate.
- Decide your exit now. A price, a date, or a goal. Written down while you are calm.
