Why Stocks Build More Wealth Than Anything Else

From 1928-2023, the S&P 500 averaged 10.2% annual returns. A single $10,000 investment in 1928 would be worth $93 million today. Real estate averaged 3-4%. Bonds: 5-6%. Gold: 2-3%. Stocks win by a landslide over long periods.

The Three Stock Investing Strategies

1. S&P 500 Index Fund (Passive, Low-Cost)

Buy VOO, SPY, or IVV—index funds that track the S&P 500. You own tiny slices of 500 largest US companies (Apple, Microsoft, Amazon, etc.). Costs 0.03% annually. Historically returns 10% per year. Warren Buffett recommends this for 99% of people. Calculate your timeline with the S&P 500 Calculator.

2. Dividend Growth Investing

Buy dividend-paying stocks (companies that share profits with shareholders). Reinvest dividends to buy more shares. Over time, your dividend income grows exponentially. Popular among retirees seeking passive income. Use the Dividend Calculator to model this.

3. Balanced Portfolio (Stocks + Bonds)

80/20 or 60/40 stock/bond allocation. Stocks provide growth, bonds provide stability. As you age, shift toward more bonds (e.g., 80% stocks at age 30 → 60% stocks at age 50). Lower returns than 100% stocks but less volatility. Model with the Portfolio Calculator.

Index Funds vs. Individual Stocks: Which Builds More Wealth?

Index Funds (S&P 500):

Individual Stocks (Stock Picking):

Verdict: For most people, S&P 500 index funds win. Easier, cheaper, and better returns than 90% of professionals.

The Power of Dividend Reinvestment

Dividend stocks pay you cash quarterly (e.g., $1,000 invested in a 4% dividend stock pays you $40/year). Reinvest those dividends to buy more shares, which generate more dividends, which buy more shares—compounding accelerates.

Example: $10,000 invested in SCHD (dividend ETF) at 3.5% yield, 8% total returns:

Dividend reinvestment adds $20,787 over 30 years on a $10,000 investment. Always reinvest dividends until you need the income.

Stock Market Crashes: Should You Worry?

The market crashes every 5-10 years. It's normal. Here's what happened historically:

Pattern: Every crash recovers. Every panic seller loses money. Every long-term holder wins.

If you held through 2000-2023 (including two massive crashes), you averaged 10.2% returns. If you sold during the crashes and bought back later, you likely underperformed.

Strategy: Keep buying during crashes. When the market falls 20-30%, you're buying stocks on sale. This is how wealth is built.
