Warren Buffett started selling chewing gum at age six and bought his first stock at eleven. His investing career now spans over 80 years. Crucially, 99% of his wealth came after he turned 50—that’s the power of compounding.
Buffett summed up his philosophy with a classic analogy:
“Life is like a snowball. The important thing is finding wet snow and a very long hill.”
-Wet snow = High-quality assets with high ROE
-Long hill = Time
The formula is simple: FV = PV × (1 + r)^n
But its power defies intuition. At a 10% annual return:
| Years | Capital Multiplier |
| 7 | ~2x |
| 14 | ~4x |
| 21 | ~8x |
| 30 | ~17x |
The secret isn’t necessarily a sky-high return—it’s time. Buffett’s ~20% annualized return isn’t otherworldly, but sustained over 60 years, it built a fortune worth tens of billions.
DCA is the most practical way for ordinary investors to harness compounding:
1.Start early: Start DCA-ing ¥1,000/month at 25 vs. ¥2,000/month at 35—by age 60, the early starter likely ends up ahead.
2.Stay consistent: Pausing during downturns is compounding’s worst enemy. Keep buying—you accumulate more shares at lower prices.
3.Reinvest dividends: Opt for dividend reinvestment so payouts compound too.
Take the CSI 300 ETF (2014–2024): DCA ¥1,000 monthly.
Total invested: ¥120k
Ending value: ~¥158k
Of that, ~¥38k comes from compounded gains.
Extend that another 10 years (assuming the same ~5% annualized return), and the ending value could reach ~¥260k—the second decade’s growth far outpaces the first.
In theory, frequent small wins can amplify returns through compounding. But grid strategies risk “breaking the grid” in strong trending markets. Actual results hinge on price paths and whether upper/lower bounds are triggered. Plus, not all capital participates in every trade—historical simulations ≠ future results.
Suppose each grid trade nets a 5% gain, triggered 20 times a year:
Simple addition: 100%
Compound calculation: (1.05)^20 ≈ 2.65x, or 165%
In practice, you won’t deploy all capital in every trade. Still, the frequent turnover in grid trading can accelerate capital velocity, creating a compounding-like effect.
Buffett’s counsel to everyday investors is refreshingly simple:
“Keep buying low-cost index funds via DCA—and then don’t peek.”
It sounds too easy. Yet few pull it off. Human nature drives us to chase rallies and panic in crashes. Successful DCA demands the opposite: buy more when prices fall, resist chasing highs.
On huice.org, you can backtest these ideas using historical data (for reference only). Seeing 10-year DCA results can help build the conviction to stay the course.
