What is the S&P 500?
The S&P 500 (Standard & Poor’s 500 Index) is a stock market index that tracks the performance of the 500 largest publicly traded companies in the United States. Some of the most well-known companies in the index include Apple, Microsoft, Amazon, Google, and Tesla.
It was created in 1957 and has since become one of the best indicators of the U.S. economy’s overall health. Investors prefer the S&P 500 because it offers diversification, stability, and long-term growth potential.
Why Invest in the S&P 500?
- Strong Historical Performance: The S&P 500 has provided an average annual return of about 10% over the long run.
- Diversification: By investing in the index, you get exposure to 500 companies across multiple industries, reducing risk compared to investing in a single stock.
- Low Maintenance: Unlike picking individual stocks, an S&P 500 investment requires minimal research and management.
- Great for Long-Term Investors: Ideal for those saving for retirement or long-term financial goals.

Mutual funds work similarly to ETFs but trade only once per day at the market close.

- Vanguard 500 Index Fund (VFIAX)
3. Fractional Shares (Great for Small Investors)
- Some brokers allow you to invest small amounts (even $1) into an ETF or mutual fund without buying full shares.
Step 4: Buy Your S&P 500 Investment
- Search for the ETF ticker symbol (e.g., VOO, SPY, IVV).
- Enter the amount you want to invest.
- Choose “Market Order” (to buy immediately) or “Limit Order” (to set a price at which you want to buy).
- Click Buy and confirm your purchase.
Step 5: Hold and Reinvest
- Leave your investment to grow over years or decades.
- Consider automatic reinvestment of dividends to maximize compound growth.
- Invest consistently over time using a strategy called dollar-cost averaging (DCA).
