The “Set-and-Forget” Investment
Imagine a robot chef that automatically cooks the same dishes as top restaurants—but charges 10x less. You get great results without hiring a master chef or tracking recipes daily.
That’s essentially what an index fund does for investing. It’s a low-cost, automated way to own a piece of the entire stock market (or a segment of it) without hand-picking stocks.
But how does it actually work? And why do experts like Warren Buffett love index funds? Let’s break it down.
What Is an Index Fund?
An index fund is a type of mutual fund or ETF that mirrors a market index (like Nifty 50 or Sensex) instead of trying to beat it.
Key Features:
✔ Passive Investing – No fund manager picking stocks.
✔ Diversified – Holds all (or most) stocks in the index.
✔ Low Cost – Lower fees than actively managed funds.
Example:
- Nifty 50 Index Fund → Holds the same 50 stocks as Nifty 50.
- S&P 500 Index Fund → Tracks the top 500 US companies.
How Do Index Funds Work?
- Choose an Index (e.g., Nifty 50, Sensex, Nasdaq).
- The Fund Buys All Stocks in That Index (in the same proportion).
- Your Money Grows with the Market – No need to track individual stocks.
Why Does This Work?
- Over time, most actively managed funds fail to beat the index.
- Index funds avoid human errors (emotional trading, wrong stock picks).
Why Invest in Index Funds?
1. Lower Fees
- Expense ratio: 0.1–0.5% (vs. 1–2% for active funds).
- Example: Saving 1% fees = ₹1 lakh extra on ₹10L over 20 years.
2. Consistent Returns
- Historically, Nifty 50 gives ~12% annual returns long-term.
3. Less Stress
- No need to research stocks or time the market.
4. Beats Most Mutual Funds
- 85% of active funds underperform their benchmark index (SEBI data).
Index Funds vs. Active Funds vs. ETFs
| Feature | Index Fund | Active Fund | ETF |
|---|---|---|---|
| Management | Passive (tracks index) | Active (fund manager picks stocks) | Passive (trades like a stock) |
| Fees | Low (0.1–0.5%) | High (1–2%) | Very low (0.05–0.2%) |
| Liquidity | Redeem anytime | Redeem anytime | Trade live on exchange |
| Best For | Long-term investors | Those who trust fund managers | Traders + investors |

✅ Busy Professionals (No time for stock research).
✅ Long-Term Investors (Retirement, wealth-building).
Warren Buffett’s Advice on Index Funds
“Most investors should just buy an S&P 500 index fund and keep adding to it periodically.”

✔ Index funds = Passive investing in market indices (Nifty, Sensex).
✔ Low cost, diversified, and stress-free.
✔ Ideal for long-term wealth-building.
✔ Start with as little as ₹500/month.
