ETFs and index funds

Low-cost funds that track a whole market — arguably the simplest, most powerful tool for everyday investors.

An index fund aims to match a market index (like a country's 500 largest companies) rather than beat it. An ETF (exchange-traded fund) is a fund that trades on a stock exchange like a share. Many ETFs are index funds.

Why they're so popular

  • Diversification: one purchase can own hundreds or thousands of companies worldwide.
  • Low cost: with no expensive stock-picking team, ongoing charges are often 0.05–0.30% a year. Low costs strongly predict good long-term outcomes. See fees.
  • Simplicity and transparency: you know exactly what you own.
  • Strong track record: index funds have historically beaten the majority of higher-cost active funds over long periods.

Index fund vs ETF

  • ETF: trades intraday at market price; buy through a broker.
  • Traditional index fund: priced once daily at NAV; often bought directly from the provider or platform. For long-term investors the practical difference is small — pick whichever is cheaper and simpler on your platform.

A common core

A single global equity index fund plus a bond fund can form a complete, diversified, low-cost portfolio. Adjust the split to your risk tolerance.

Key takeaway

For most people, broad, low-cost index funds/ETFs are the simplest route to sensible, diversified, long-term investing.
