US equities, as measured by the S&P 500 Index, compounded at a remarkable average annual rate of 13.5% from 2009 to 2024.1 Investors who eschewed diversification in favor of US equities saw their portfolios handily outperform more diversified portfolios—until now. 

The long-awaited broadening of returns beyond US large-cap equities began before President Donald Trump’s historic tariff announcement on April 2 sparked a significant uptick in volatility, and there are compelling reasons why this trend could continue going forward. 

Risk-conscious investors may want to consider three strategies: diversifying with fixed income, reallocating to international equities, and incorporating dividend-paying stocks.

 

1. Diversifying With Fixed Income
Even after the dramatic sell-off in the wake of Trump’s tariff announcement, US equities are still trading at a premium valuation on a forward-looking basis.2 Valuations have fallen, but still seem to be pricing in a swift resolution of trade disputes and continued optimism about artificial intelligence. 

One way to measure the relative value of stocks vs. bonds is with the earnings yield, which measures the S&P 500 Index’s most recent 12-month earnings divided by its current market price. The yield on the 10-year US Treasury recently surpassed the S&P 500 Index’s earnings yield (FIGURE 1). This may indicate that bonds are currently a better value than stocks.

After trading at a premium from 2018 until early 2022, the average price of bonds in the Bloomberg US Aggregate Bond Index (the Agg) has been trading at a discount (FIGURE 2). This fact, coupled with the potential for rate cuts by the Federal Reserve (Fed), could mean attractive total return for bonds going forward.

Another compelling argument for bonds is their attractive yields. The best predictor of future bond returns has historically been their current yield. When you overlay the ending yield of the Agg with its 10-year rolling returns, the strong correlation between yield and return is striking (FIGURE 3).

Bonds have experienced significantly lower maximum annual drawdowns than stocks during periods of market stress.

Fixed Income Has Experienced Significantly Lower Drawdowns

One of the main reasons for owning bonds is to hedge against equity volatility in a portfolio. Since 1985, bonds have averaged a maximum average annual loss of -2.3% vs. a -14.0% maximum average annual loss for stocks (FIGURE 4).

2. Reallocating to International Equities

US large-cap equities performed so well in the aftermath of the Global Financial Crisis that they were often the best-performing asset class over the past 15 years—significantly outperforming diversified portfolios. This led some market commentators to declare that we’ve been in “a bear market for diversification.”3

There are good reasons why US equities should be the cornerstone of investor portfolios: The US has a unique mix of highly innovative companies, high liquidity, and a business-friendly regulatory environment. Nevertheless, prudent risk management suggests that overlooking most of the world’s companies may not be wise (FIGURE 5). Many investors are surprised to discover that most of the best-performing stocks each year are based outside the US (FIGURE 6).

International Equities Are Less Concentrated and More Diversified by Sector

The concentration risk in many US large-cap portfolios has received a great deal of attention in recent years—and with good reason. Concentrated portfolios benefit investors when the largest holdings in the portfolio perform well, but they can significantly harm investors when they perform poorly. The S&P 500 Index, which is the basis for many of the largest mutual funds and ETFs in retirement plans and IRAs, has much more concentration risk than a comparable international index (FIGURE 7).

In addition to concentration by holdings, the S&P 500 Index is also significantly more concentrated by sector than a representative international index (FIGURE 8). The S&P 500 Index has a 30% weighting in technology, but this figure doesn’t take into account tech-oriented companies such as Amazon, Meta, Alphabet, and Tesla that are classified in different sectors. Including those types of companies pushes the technology and tech-adjacent allocation to approximately 40%.

Important Risks: Investing involves risk, including the possible loss of principal. • Fixed income security risks include credit, liquidity, call, duration, and interest-rate risk. As interest rates rise, bond prices generally fall. • For dividend-paying stocks, dividends are not guaranteed and may decrease without notice. • Foreign investments may be more volatile and less liquid than US investments and are subject to the risk of currency fluctuations and adverse political, economic and regulatory developments. These risks may be greater, and include additional risks, for investments in emerging markets.
