The S&P 500 is a well-known benchmark that tracks the performance of about 500 of the largest U.S. companies. Many investors use it as a core part of their retirement portfolios because it is diversified and efficient. Over time, the S&P 500 has delivered average annual returns of about 10%. Low-cost index funds and ETFs that follow the S&P 500 are popular choices for people saving for retirement.
How you invest in the S&P 500 should change as you get older. Your investment strategy depends on your age, risk tolerance, and retirement goals. Here’s how financial experts suggest you approach S&P 500 investing at different life stages.
Young Investors (Ages 20–40): Focus on Growth
High Stock Allocation
Young investors have time on their side. They can handle the ups and downs of the stock market because they have years to recover from losses. Experts recommend that people in their 20s keep up to 90% of their portfolio in stocks. Even in your 40s, an 80% stock allocation is often suitable.
Long-Term Investing
Passive investing in S&P 500 index funds or ETFs, such as VOO or SPY, is a smart move for young investors. The best results come from buying and holding over the long term, rather than trying to time the market.
Dollar-Cost Averaging
Investing a fixed amount regularly, known as dollar-cost averaging, helps smooth out market ups and downs. This strategy builds discipline and reduces emotional reactions to market swings.
Stay Calm During Market Drops
Market downturns are normal. If your investment plan matches your goals and risk tolerance, it’s usually best to stay invested—even when the market falls.
Mid-Career Investors (Ages 40–50): Start Rebalancing
Keep Contributing
During these years, it’s important to continue investing, even if life gets expensive. If your employer matches your retirement contributions, try to invest at least enough to get the full match.
Shift Toward Safety
As retirement gets closer, gradually move some money from stocks to safer investments like bonds. This helps protect your savings from big market swings.
The Rule of 100 (and Variations)
A common guideline is to subtract your age from 100 to find your ideal stock percentage. Some experts suggest using 110 or even 120 minus your age for a higher stock allocation. However, these are just starting points—your personal situation matters most.
Rebalancing is Key
Review your portfolio regularly. If stocks have grown to take up too much of your investments, sell some and buy more bonds or other assets to keep your risk balanced.
Pre-Retirees (Ages 50+): Protect What You’ve Built
Lower Risk, But Don’t Abandon Stocks
As you near retirement, focus more on protecting your savings. This doesn’t mean avoiding stocks completely. Keeping some S&P 500 exposure can help your money grow, but it should be part of a diversified mix.
Diversification Matters
Spread your investments across different asset types, such as stocks, bonds, and government securities. Even within stocks, don’t put everything into the S&P 500, as a few big tech companies now make up a large part of the index.
Match Investments to Retirement Needs
As retirement approaches, shift your portfolio to match your expected expenses and income needs. Consider healthcare, travel, and housing costs.
