Is Overreliance on U.S. Stocks a Retirement Risk for Americans?

The investment landscape for American retirement savers continues to shift but one trend remains concerning: the overwhelming reliance on U.S. stocks in retirement portfolios. In light of recent market performance during the first 100 days of Donald Trump’s second term, it’s crucial for investors to assess the impact of home country bias on their retirement savings. This article delves into the implications of this overexposure and the importance of diversification in achieving financial security.

Diversification Strategies in the Wake of Market Volatility

If you successfully diversified your investment portfolio ahead of Trump’s second term, congratulations are in order. Investments in safer assets like gold and silver have yielded notable gains, with gold rising 25% and silver up 13% since Trump’s inauguration on January 20, 2025. Additionally, currencies such as the Japanese yen and Mexican peso have strengthened against the U.S. dollar, offering substantial returns for savvy investors who opted for diversification.

Despite the prudent moves of some, most Americans remain heavily invested in U.S. equities to the detriment of their long-term financial health. According to Vanguard’s “How America Saves” report, the typical investor allocates a staggering 79% of their retirement savings into stocks, predominantly U.S. stocks. The implication of this home country bias can be severe, particularly during times of market turbulence.

The Performance Gap: U.S. Stocks vs. International Markets

Market data since Trump’s inauguration reveals troubling trends for those who relied solely on U.S. stocks. The S&P 500 index has suffered a 6% decline since January, with even steeper losses observed in the Russell 2000 (down 12%). Comparatively, those who diversified into international markets fared better – the iShares Core MSCI EAFE index, which tracks stocks from Europe, Australasia, and the Far East, returned 13% during the same timeframe. This stark contrast highlights the advantages of global diversification, emphasizing how exposure to international assets can mitigate risks associated with domestic market downturns.

Understanding Home Country Bias and Recency Bias

Investors frequently fall prey to home country bias, an inclination to favor domestic investments that can leave their portfolios overly susceptible to U.S. market fluctuations. While proponents of American equities argue that historical outperformance justifies this bias, they overlook the economic fallacy of recency bias, which overemphasizes recent trends and ignores longer-term patterns.

An examination of returns from indices illustrates this point: an investor in the Vanguard Total U.S. Stock Market Index Fund would have lost 8% since inauguration, whereas someone investing in the Vanguard Total World Stock Market Index Fund would be down only 3%. If the investor had split their assets evenly between the U.S. fund and the Vanguard FTSE Developed Markets Fund, they would break even. These findings highlight the necessity for investors to diversify their portfolios across various geographical regions and asset classes.

Bonds: The Underestimated Asset Class

Amidst market volatility, bonds have showcased stability, with U.S. Treasury bonds and inflation-protected securities returning approximately 3% each since Trump’s inauguration. Investment-grade corporate bonds also demonstrated resilience, yielding 2%. For 401(k) participants invested in target-date funds, the performance largely depends on the fund’s equity allocation. For instance, the Vanguard LifeStrategy Growth Fund (80% stocks) has declined by 1.5%, while the Vanguard LifeStrategy Income Fund (80% bonds) has appreciated by 1.5%. This serves as a reminder that a diversified portfolio can prove advantageous when navigating choppy market waters.

Lessons from Past Market Volatility

The current climate should not be perceived as uniquely tumultuous. Historical analysis reveals varying degrees of market downturns during the initial phases of other presidential terms, including Barack Obama’s first term in 2009 and Franklin Roosevelt’s second term in 1937. While market performance can fluctuate dramatically based on policy changes and external events, the role of diversification remains crucial for long-term investors.

Concluding Thoughts on Retirement Strategy

Amid the volatility and uncertainty that accompanies political and economic changes, investors should not forsake diversification as a cornerstone of their investment strategy. By reducing reliance on U.S. stocks and embracing a more varied portfolio, retirement savers can better position themselves to withstand market fluctuations. Ultimately, educating oneself about the risks of home country and recency biases will empower investors to make informed decisions that are essential for achieving their financial goals.
