The three-fund portfolio is the gold standard of lazy investing. Popularized by Bogleheads in the US, the concept adapts beautifully to India: pick one domestic equity fund, one international equity fund, and one debt fund. Rebalance once a year. Done.
Fund 1: Domestic equity
A Nifty 50 or Nifty 100 index fund covers India's largest, most liquid companies. Expense ratios run 0.05%–0.20%, and over 10-year periods these funds have outperformed the majority of active large cap managers. If you want broader exposure, a Nifty 500 index fund adds mid and small caps at a slight cost premium.
Fund 2: International equity
Most Indian investors have 100% domestic exposure — a concentration risk masked by home bias. An S&P 500 or MSCI World feeder fund adds geographic diversification. When Indian markets wobble due to local factors (elections, RBI surprises, FII outflows), global exposure acts as a shock absorber. Allocate 15%–25% here.
Fund 3: Debt
A short-duration or corporate bond fund stabilizes the portfolio and provides rebalancing ammunition. When equities crash, you sell debt (which held steady) to buy cheap equity. When equities soar, you trim and park in debt. This mechanical rebalancing forces you to buy low and sell high — the opposite of what most investors do emotionally.
The allocation question
A common starting formula: subtract your age from 100 for equity allocation. A 30-year-old might go 70% equity (split domestic + international) and 30% debt. Aggressive investors push equity to 80%+; conservative ones pull it to 60%. There is no perfect number — only the one you can hold through a 40% drawdown without panic-selling.
Why it works
Simplicity removes decision fatigue. Three funds means three things to monitor, minimal overlap, and rock-bottom costs. The enemy of returns isn't a bad fund pick — it's the investor who churns, times, and overcomplicates. Use our comparison tool to evaluate index funds side by side.
