What Index fund means in practice
Think of an index fund as buying a slice of the entire stock market—like owning tiny pieces of hundreds of companies all at once. You don’t pick winners; you just ride the overall market’s performance. This makes it simple, low-risk, and perfect for retirement savings or growing your money over time without needing to be a finance expert.

- 2Choose funds with expense ratios below 0.20%
- 3Opt for ETFs instead of mutual funds when possible—they’re often cheaper
Mistakes to avoid
- Choosing funds just because they have 'index' in the name
- Ignoring fees when comparing similar funds
