How does index investing work?

Quick answer

Index investing means buying a fund that simply tracks a whole market index, like the S&P 500, instead of trying to pick winning stocks. You get broad diversification at low cost, matching the market's overall return rather than beating it.

Step by step

  1. You buy a fund that mirrors a market index.
  2. It gives instant, broad diversification.
  3. Fees are low since there's no active stock-picking.
  4. It aims to match the market, not beat it.
