UBS Downgrades US Stocks, Citing Fading Drivers
Investment bank UBS has downgraded its outlook for U.S. equities, warning that key market drivers like corporate buybacks are fading. The bank highlighted "asymmetric structural downside risks" to the U.S. dollar, suggesting that the factors behind years of American market outperformance are beginning to weaken.
The valuation gap between U.S. stocks and their global counterparts has become a primary concern. According to UBS, U.S. equities are trading at a 35% premium to international markets after adjusting for sector differences, a significant jump from the 4% average premium seen since 2010. This stretched valuation is prompting some institutional investors to redirect new capital to overseas markets. A weakening U.S. dollar is another headwind. Analysts at multiple firms, including Morgan Stanley and ING, forecast a decline for the dollar in the first half of 2026, with UBS targeting a EUR/USD rate of 1.22. Historically, a falling dollar has often coincided with U.S. stocks underperforming global markets, creating a more favorable environment for international investments. This shift is already visible in 2026 market performance. While the S&P 500 has remained relatively flat, the MSCI World ex-USA Index has gained approximately 8%. Other markets have seen even stronger performance, with Japan's Nikkei 225 rising about 17% and Europe's Stoxx 600 up around 7%. The boost from corporate share buybacks, a long-time driver of U.S. market outperformance, is also diminishing. While the total dollar value of buybacks reached record levels in 2025, the number of companies announcing new repurchase plans hit a 10-year low in the third quarter of that year, indicating the trend is losing breadth. Heightened policy uncertainty in Washington adds another layer of risk for investors. Specific policy proposals, including potential caps on credit card interest rates, new import tariffs, and possible restrictions on private equity investments in the housing market, have created an unpredictable environment for corporate planning and investment. Despite the downgrade to "Neutral," UBS strategists are not entirely bearish on the U.S. market, maintaining a year-end target of 7,500 for the S&P 500. The bank acknowledges that the U.S. retains a significant lead in the adoption and development of artificial intelligence, which is expected to support earnings growth in related sectors.
