UBS downgrades the U.S. stock market. Here’s what has the investment bank worried

UBS’ prime fairness strategist dialed again his view on U.S. shares, citing mounting dangers from a weakening greenback, stretched valuations and coverage turbulence in Washington.

Andrew Garthwaite, head of worldwide fairness technique on the funding financial institution, downgraded American equities to “benchmark” in a completely invested world fairness portfolio, arguing that the elements that powered years of outperformance are beginning to fade.

The greenback danger is a central concern, Garthwaite wrote. UBS forecasts the euro climbing to $1.22 by the tip of the primary quarter and sees “uneven structural draw back dangers” to the dollar. Traditionally, when the greenback’s trade-weighted index falls 10%, U.S. equities underperform by roughly 4% in unhedged phrases, in response to the financial institution.

Overseas markets are trouncing the U.S. this yr as a weaker greenback and cheaper valuations draw capital abroad. The MSCI World ex-US index has gained about 8% in 2026, in contrast with the little modified efficiency for the S&P 500. Japan’s Nikkei 225 has rallied 17% yr to this point, whereas the Stoxx Europe 600 is up 7%, underscoring a pointy rotation away from American equities. U.S. shares struggled once more Friday as traders fretted over the potential downsides of the bogus intelligence build-out and protracted inflation at house.

One other pillar of U.S. inventory energy — company buybacks — can be shedding its edge, the financial institution stated. The buyback yield within the U.S. is now solely roughly on par with world friends, eroding what had been a key help for earnings per share development and investor flows, UBS stated. The mixed shareholder yield from dividends and buybacks within the U.S. is now about half that of Europe, the financial institution stated.

“The buybacks yield is now not distinctive and this had been an essential driver of funds move, EPS and valuation,” Garthwaite wrote.

Valuations add to the unease. UBS calculates that the sector-adjusted price-earnings ratio for U.S. shares is 35% above worldwide friends, versus a mean premium of about 4% since 2010. Roughly 60% of sectors commerce not solely at larger multiples than their world counterparts but additionally above their very own historic premium, the strategist wrote.

Coverage volatility beneath President Donald Trump is one other headwind. This yr has introduced shifts in tariff coverage, proposals to cap bank card rates of interest, potential limits on personal fairness funding in housing, renewed scrutiny of drug pricing, and strategies to curb dividends and buybacks for protection firms, UBS stated.

Nonetheless, the famous strategist stopped wanting turning outright bearish. Garthwaite stated the U.S. economic system and equities have a tendency to learn greater than friends when markets are within the early phases of a possible bubble. The financial institution additionally expects synthetic intelligence adoption to outpace most different main areas, with the doable exception of China, serving to maintain earnings development throughout key industries.

UBS strategist Sean Simonds set a year-end goal of seven,500 for the S&P 500, in contrast with a mean forecast of seven,629 amongst 14 prime strategists, in response to CNBC Professional’s strategist survey.
