Index funds are one of the easiest, most powerful ways to start investing—even if you know nothing about the stock market. In this guide, you’ll learn exactly what they are, how they work, and why they’re a favorite for long-term investors around the world.

What Is an Index Fund?

An index fund is a type of investment fund or ETF (exchange-traded fund) that automatically tracks a specific market index. Instead of trying to beat the market, it simply copies it. That means if the market grows, your investment grows too.

Example: If you invest in an S&P 500 index fund, your money is spread across the 500 largest U.S. companies like Apple, Microsoft, and Amazon—all in one fund.

How Do Index Funds Work?

Index funds are managed passively. That means no one is choosing what stocks to buy or sell. The fund just mirrors the index it’s tracking. This keeps costs low and makes performance predictable.

Popular Indexes:

  • S&P 500 – Tracks 500 major U.S. companies
  • NASDAQ 100 – Tech-focused U.S. companies
  • FTSE 100 – 100 large UK companies
  • MSCI World – Global companies across countries

Why Are Index Funds So Popular?

Because they’re low-cost, diversified, and consistently strong performers. Famous investors like Warren Buffett recommend them for most people, especially beginners.

“A low-cost index fund is the most sensible equity investment for the great majority of investors.” – Warren Buffett
