- S&P 500: Higher volatility due to tech-heavy composition, but higher growth potential
Implication: Conservative investors may choose FTSE 100 for income and stability. Aggressive investors seeking capital appreciation may lean toward the S&P 500.
6. Currency and Global Exposure
- FTSE 100: Although UK-based, many companies earn revenue globally, so returns can be affected by currency fluctuations (GBP vs USD/EUR).

Currency changes can significantly impact returns for international investors.

Strategy Tip: Many global investors diversify by holding both indices to balance growth and income.
Conclusion
The FTSE 100 and S&P 500 serve different purposes in an investor’s portfolio. The FTSE 100 provides stability and consistent dividends, while the S&P 500 offers exposure to high-growth companies and long-term capital gains.
