Index fund investing is one of the most powerful wealth-building strategies available to everyday investors. Warren Buffett himself recommends it.

An index fund tracks a market index like the S&P 500, giving you instant diversification across hundreds of companies with a single purchase.

The key advantages: extremely low fees (often 0.03-0.10%), broad diversification, and historically strong returns averaging 10% annually over the long term.

To get started, open a brokerage account with Vanguard, Fidelity, or Schwab. Start with whatever you can afford, even 50 dollars per month adds up significantly over time.
