UBS Downgrades US Stocks on Fading Tailwinds
UBS has downgraded its outlook for U.S. stocks, warning that key drivers of the market's recent outperformance are beginning to fade. The investment bank cited a slowdown in corporate buybacks and "asymmetric structural downside risks" to the U.S. dollar as primary concerns.
The U.S. dollar index experienced a significant decline of approximately 8-9% in 2025, ending a period of steady appreciation. Entering 2026, the greenback has been trading below the key 100 level, hitting a four-year low in January as the Federal Reserve pivots towards interest rate cuts. This potential for a weaker dollar is echoed by multiple financial institutions, with Morgan Stanley forecasting the U.S. dollar index could drop to 94 in the second quarter of 2026. The expected Fed easing has spurred capital outflows from U.S. assets, with a net outflow of $22 billion from the stock market in January 2026 alone. Corporate buybacks, a major driver of stock performance, reached a record pace in 2025, with U.S. companies on track to repurchase $1.1 trillion to $1.2 trillion of their own shares. This activity was highly concentrated, with the top 20 companies in the S&P 500 accounting for more than half of the total value. Looking ahead, Goldman Sachs projects that while the scale of U.S. stock buybacks will grow in 2026 compared to 2025, the total nominal value will likely remain below the levels seen in 2024. This suggests a potential reduction in a key source of demand for U.S. equities. Despite the concerns raised by UBS, other major firms maintain a more bullish outlook. Goldman Sachs and J.P. Morgan both forecast double-digit gains for the S&P 500 in 2026, citing expectations for strong earnings growth, partly fueled by investment in artificial intelligence. The downgrade comes after the U.S. stock market reached an all-time high in January 2026. So far this year, performance has been mixed, with a notable rotation occurring as investors shift from last year's mega-cap tech leaders to industrial, energy, and consumer defensive stocks.
