U.S. Real Estate | 4.5% |
Gold | 6.5% |
These historical return comparisons demonstrate why many financial advisors recommend a diversified portfolio that includes multiple asset classes. While stocks have provided the highest long-term returns, they also come with higher risk and volatility.

Risks and Considerations of Long-Term Investing
Market Volatility
While stocks have historically provided strong long-term returns, they can be volatile in the short term and even end the year down. The market has experienced significant drops in the past – and probably will again in the future – but historical data shows that maintaining a long-term perspective has typically rewarded patient investors.
Impact of Inflation
With historical inflation averaging around 2-3% annually, it’s crucial to consider how this affects your investment’s purchasing power. This is one reason why stocks, which have historically outpaced inflation, can be an effective long-term investment vehicle. During periods of high inflation, say 5% per year, if you earn 5% on your investments you effectively have earned zero in terms of real return.
Interest Rates
Interest rates directly and indirectly impact investment returns and market behavior. When central banks adjust rates, it creates a ripple effect throughout the economy and financial markets. Higher interest rates can reduce corporate profits through increased borrowing costs, with growth stocks often more sensitive to rate changes than value stocks.
Economic Cycles
Economic cycles, also known as business cycles, typically progress through four main phases that can span several years: expansion, peak, contraction, and trough. Understanding these cycles helps investors anticipate market movements and adjust strategies accordingly. Over the span of three decades, one might expect to experience several such cycles from trough to peak.
Global Events
In today’s interconnected world, global events and geopolitical risks can rapidly impact investment returns across all markets. Understanding these connections helps investors prepare for and respond to international developments that may persist over the next several decades, including increased globalization, climate change, and a shift to green energy.
Company-Specific Risks
Individual companies face unique risks that can significantly impact investment returns, regardless of broader market conditions. Holding a diversified portfolio that includes stocks of several industry sectors, size, geographic proximity, and years in business can help mitigate these risks. Buying and holding a passive investment in something like an S&P 500 index fund can be a cost-effective way to diversify.
While economic downturns and bear markets can be unsettling, they often create opportunities for long-term investors. Market history shows that downturns, though painful in the moment, are typically temporary setbacks in a longer upward trend. During these periods, your regular investments buy shares at reduced prices, which can enhance long-term returns when the market recovers. Think of downturns as temporary sales on quality investments. The key is maintaining perspective and staying committed to your investment strategy rather than reacting emotionally to short-term market movements.
Research on Historical Investing Returns
Research by Dr. Jeremy Siegel and John Bogle, the founder of Vanguard, looked back over a period of 196 years and compared the real returns of stocks, bonds, and gold. They found that if an investor had started around the year 1810 (the New York Stock Exchange was actually founded in 1817) and put $10,000 in gold, their inflation-adjusted portfolio would be worth just $26,000. The same investment in bonds would have grown to $8 million. However, had the investor picked stocks in 1810, he would have turned his $10,000 into $5.6 billion.
Stocks are still the big winner if you select a more realistic time frame; most investors have a 30- to 40-year horizon, not 200 years. Between January 1980 and January 2010, the average annualized growth rate of the S&P 500 was 8.15%. The Dow Jones averaged 8.81% over the same period, while the NASDAQ jumped 9.51% yearly. Bond returns averaged less than 3% between 1980 and 2010. The dollar had an average inflation rate of 3.30% per year between 1980–2010, meaning that $1,000 in a savings account in 1980 would have a real value of $2,646.31 in 2010.
The 30-year period between 1985 and 2015 was even stronger. The S&P averaged 8.73%, the Dow Jones averaged 9.33%, and the NASDAQ averaged an impressive 10.34% per year.
What Are the Tax Implications of Investing in Stocks for 30 Years?
Long-term investments (i.e., held over 1 year) are taxed at preferential long-term capital gains tax rates: 0%, 15%, or 20%, depending on your income. Using tax-advantaged accounts like Roth IRAs can help eliminate taxes on gains entirely. Regular rebalancing can also be used for tax-loss harvesting to offset realized gains.
What Are Smart Ways to Choose Stocks for Long-Term Investment?
A wise approach to choosing stocks for long-term investment focuses on fundamental strength rather than short-term market movements. Look for companies that have demonstrated staying power through multiple economic cycles, maintain healthy balance sheets, and hold strong competitive positions in their industries. These companies typically generate consistent cash flow and, ideally, share profits with stockholders through dividends or buybacks.
For many investors, though, the simplest and most effective approach is investing in low-cost index funds that track the broad market, providing instant diversification and reducing the risk of picking individual stocks.
What Are the Best Platforms for Automating Monthly Stock Investments?
Several mainstream investment platforms have made automated investing both easy and cost-effective. Fidelity and Vanguard, among others, are particularly well-suited for long-term investors, offering easy-to-use automatic investment plans and a wide selection of no-fee funds. Charles Schwab provides an excellent combination of fractional share investing and automation, making it perfect for small monthly investments. And, M1 Finance has revolutionized the space with its automated portfolio management and rebalancing features. Roboadvisors are another easy-to-use automated option that can be set up with automatic recurring deposits. The key is choosing a platform that aligns with your investment style and offers the specific features you need, whether that’s detailed research tools or a simple, hands-off approach.
What Are the Benefits of Dollar-Cost Averaging for Long-Term Investors?
Dollar-cost averaging takes the guesswork out of investing by establishing a routine of regular investments regardless of market conditions. Instead of trying to time the market perfectly, you invest the same amount each month (say, $100), naturally buying more shares when prices are lower and fewer when they’re higher. This systematic approach not only helps manage risk but also removes emotional decision-making from the investment process. Over time, this strategy tends to result in a lower average cost per share than trying to pick the perfect moment to invest.
The Bottom Line
Investing just $100 monthly in stocks over a period of 30 years could potentially grow to a significant sum, thanks to the power of compound interest and historical stock market returns. While there are risks to consider, a disciplined approach to regular investing, combined with a long-term perspective, can help build substantial wealth over time.
