UBS Downgrades US Stocks on Fading Buybacks
Investment bank UBS has downgraded the U.S. stock market, warning that key drivers of its recent outperformance are weakening. The bank cited fading corporate buybacks and an “asymmetric structural downside risk” to the U.S. dollar amid growing geopolitical instability as primary concerns for investors.
This downgrade shifts UBS's rating on U.S. equities from "Overweight" to "Neutral," a significant change that aligns U.S. stocks with a standard benchmark allocation in global portfolios. The bank has maintained its "Overweight" recommendation for emerging market stocks, suggesting a potential rotation of capital to other regions. A key driver of past U.S. market outperformance, corporate stock buybacks, is losing its edge. UBS notes that the buyback yield for U.S. stocks is now largely on par with the global average and even falls short of markets like the United Kingdom, diminishing a crucial support for earnings-per-share growth. Concerns over the U.S. dollar are central to the downgrade. Strategists at UBS forecast the euro will appreciate to $1.22 against the dollar and warn of "asymmetric structural downside risks." Historically, a 10% drop in the dollar's trade-weighted index has led to U.S. stocks underperforming the global market by about 4%. Valuations for U.S. stocks are also a major concern. After adjusting for sector differences, the price-to-earnings ratio of U.S. equities is roughly 35% higher than comparable international markets. This represents a significant premium over the historical average of about 4% since 2010. This sentiment is reflected in recent market performance. Year-to-date, several overseas indexes like the MSCI World ex-USA Index, Japan's Nikkei 225, and Europe's Stoxx 600 have outperformed the S&P 500, which has remained relatively flat. The downgrade also points to policy uncertainty and its potential impact on corporate spending and earnings. UBS suggests that when global economic growth accelerates past 3.5%, as it's expected to, U.S. stocks historically tend to underperform relative to global markets. However, not all of Wall Street shares UBS's caution. Many analysts entered 2026 with optimistic forecasts, predicting the S&P 500 would continue its multi-year rise, driven by factors like accelerated earnings growth and investments in artificial intelligence.
