Understanding S&P 500 ETFs: The Cornerstone of Long-Term Investing
S&P 500 ETFs track the Standard & Poor's 500 Index, representing approximately 80% of the total US equity market capitalization. Constantly screened for profitability, liquidity, and financial viability, the S&P 500 has a long history across many economic cycles, though returns are not guaranteed and it has had significant declines.

How to Evaluate S&P 500 ETFs (Investor Checklist)
- Expense Ratios Matter Over Decades: Over a 30-year horizon, saving 7 basis points between VOO (0.03%) and SPY (0.09%) compounds into thousands of dollars in preserved capital.
- Understand Market-Cap Weighting Concentration: The top 10 companies in the S&P 500 currently represent over 30%-35% of total index weight, heavily driven by big tech.
- Reinvest Dividends Automatically: Historically, reinvested dividends have made up a meaningful share of the S&P 500’s total return.
