What Is an Index Fund and Why Should You Invest?

Index Funds — The Simplest Way to Build Wealth

An index fund is a type of mutual fund or ETF that tracks a market index (like the S&P 500 or Nifty 50). Instead of a fund manager picking stocks, it simply buys all the stocks in the index.

Why Index Funds Win

Lower fees: 0.03-0.20% vs 1-2% for actively managed funds. On $100,000, that saves $1,000-2,000/year.

Better returns: Over 90% of actively managed funds fail to beat their benchmark index over 15 years.

Instant diversification: One fund gives you exposure to hundreds or thousands of companies.

No research needed: You do not need to pick individual stocks or time the market.

Start with a broad market index fund and invest consistently through dollar cost averaging.
