Index funds, explained simply

Owning a small slice of a whole market.

5 min read

An index fund is a mutual fund or exchange-traded fund (ETF) that aims to match the performance of a market index, like a broad group of US stocks, rather than pick individual winners.

Why many beginners look at them

  • Broad diversification in a single fund
  • Often lower costs than actively managed funds
  • No need to pick individual stocks

Keep in mind

  • Index funds still go up and down with the market
  • Not all index funds are low cost; check the expense ratio
  • Different indexes cover very different things: US stocks, international stocks, bonds
