What Are Index Funds?
Index funds are investment vehicles that track market indexes like the S&P 500, offering instant diversification. Unlike individual stocks, they spread your money across hundreds of companies. Legendary investors like Warren Buffett recommend them because they typically outperform actively managed funds while charging lower fees.
Why They're Perfect for Passive Income
For beginners, index funds eliminate the stress of stock-picking. As Fidelity ZERO Large Cap Index (FNILX) shows, some funds even have 0% expense ratios. Historically, the S&P 500 averages 8-10% annual returns. You just invest regularly and let compounding work over time.
Getting Started in 3 Steps
1. Choose Your Brokerage
Open an account with platforms like Vanguard, Fidelity, or Charles Schwab. Many offer commission-free ETF trading and low minimum investments.
2. Pick Your Fund
Top beginner options:
- Vanguard S&P 500 ETF (VOO): 0.03% fee
- Schwab S&P 500 Index (SWPPX): 0.02% fee
- Fidelity ZERO Large Cap: 0% fee
3. Automate Investments
Set up recurring deposits. Even $50/month grows significantly over decades. Use dollar-cost averaging to smooth out market volatility.
