Diversification Is Key For Long-Term Investing

Diversification across different asset classes is crucial for managing risk in a decades-long portfolio. Investing solely in stocks leaves you exposed to volatility and potential crashes. Adding bonds, real estate, commodities, and other assets helps smooth out returns over time. Diversification means you won’t get the highest possible returns, but it provides stability and reduces significant losses.

The 60/40 Stock/Bond Portfolio Has Historically Performed Well

The traditional 60/40 stock/bond portfolio allocation has proven itself over almost a century of market ups and downs. With 60% invested in stocks for growth and 40% in bonds for stability, this portfolio has achieved solid returns averaging close to a 7.8% annually for the past 30 years. It experiences some down years but far fewer than a 100% stock portfolio. For investors with a moderate risk tolerance, 60/40 provides a time-tested formula.[1]

An 80/20 Stock/Bond Split Offers More Growth Potential

An 80/20 stock/bond portfolio may be preferable for investors focused on maximizing long-term returns. With 80% allocated to equities, this portfolio has historically achieved over 8.81% average annual returns over the past 30 years. However, the tradeoff is higher volatility – you’ll see more negative return years compared to 60/40. If you have an increased risk tolerance and a lengthy investing timeline, 80/20 could optimize your overall gains.[2]

Going 100% Stocks Maximizes Returns But Increases Volatility.

An aggressive 100% stock portfolio has posted the highest historical returns. The average yearly return of the S&P 500 is 9.86% over the last 30 years, as of the end of September 2023. This assumes dividends are reinvested. Adjusted for inflation, the 30-year average stock market return (including dividends) is 7.14%However, it also sees severe downturns during market crashes, with the worst year on record showing a 43% loss. The long-term returns could be spectacular if you can stomach this rollercoaster and won’t need to sell for decades. But most investors are better off with at least some bond allocation to smooth out the violent swings.[3]

Consider Your Age And Risk Tolerance When Choosing An Asset Allocation

Your age and willingness to accept losses should guide your asset allocation. When younger, a higher percentage in equities takes advantage of long time horizons and compounding. As you near retirement, bonds become more important for preserving capital. And your emotional reaction to market volatility factors in – if you lose sleep during downturns, you likely need a more conservative asset mix overall.

Target Date Funds Are A Simple Starting Point For Beginners

Target date funds provide a hands-off approach to asset allocation that automatically adjusts over time. The fund manager selects an appropriate stock/bond mix based on the target retirement year. You have a higher percentage of capital in stocks when you are young and your bond exposure slowly increases as you near retirement age. This makes target date funds an excellent choice for investing novices just getting started. As your wealth grows, you should control your asset allocation more directly.

Don’t Get Hung Up On Asset Allocation When Just Starting Out

When first investing, your priority should be getting started, saving capital to invest, and putting your money to work. Start with automatic deposits into your retirement account at your job and try to get the full company 401(k) match. Take your time finding the perfect asset allocation from day one. Instead, choose a broadly diversified index fund that exposes you to the whole market. As you gain experience and your portfolio grows, you can fine-tune your allocation to suit your goals and risk tolerance.

Re-Evaluate Your Asset Mix As You Get Closer To Retirement

While more aggressive when younger, your asset allocation should become more conservative as retirement approaches. The typical trajectory is to reduce equity exposure and increase fixed-income assets like bonds. This helps protect your nest egg right before and during withdrawals. You should revise your portfolio annually and consider shifting to a more stable asset mix in the ten years before retirement?
