Barclays Backs U.S. Stocks Amid Energy-Driven Volatility and AI-Led Earnings Upside

Barclays told clients that the combination of a sudden energy-price shock and accelerating AI-driven corporate investment supports remaining overweight U.S. equities. The bank highlighted resilient earnings momentum, adjusted valuations in Big Tech, and a policy gap between the Federal Reserve and the European Central Bank as reasons to favor the U.S. market.

Key Points

  • Barclays recommends staying overweight U.S. equities, citing AI-driven earnings upside and a growing investment cycle - sectors impacted: technology, industrials, capital goods.
  • The bank forecasts U.S. corporate earnings to rise about 15% in 2026 and notes that Big Tech forward multiples have fallen to their lowest levels since early 2025 - sectors impacted: technology, communications.
  • Monetary policy divergence - the Fed has more room to overlook energy-driven inflation than the ECB, supporting a relative advantage for U.S. equities - sectors impacted: financials, sovereign bond markets, equities.

Barclays is recommending that investors retain an overweight position in U.S. equities, arguing that a distinctive mix of higher energy prices and an AI-led earnings upswing makes the U.S. market the preferable destination for risk assets. In a client note, analyst Ajay Rajadhyaksha framed the view with the phrase "fear the headlines, but trust the cycle," and cautioned that while headline risks are real, "the worst-case scenarios will not materialize."

The bank pointed to recent market stress driven by a spike in energy prices after the U.S.-Iran conflict. That shock has produced headwinds for both stocks and bonds this quarter, but Barclays sees it as a near-term disruption rather than a lasting systemic shock.

On the fundamentals, Barclays noted that the S&P 500 has declined about 3% so far this year, yet it identifies several structural tailwinds supporting U.S. equities. Central to the argument is broadening adoption of artificial intelligence across corporate America and a widening investment cycle across Western economies, which Barclays expects to underpin earnings and capital expenditure.

The bank projects U.S. corporate earnings will increase roughly 15% in 2026, and it described that earnings outlook as the "key differentiator" when comparing U.S. prospects with Europe. Barclays also highlighted that valuations have adjusted, observing that forward multiples for Big Tech names have contracted to their lowest levels since early 2025 even as analysts' earnings revisions have strengthened.

This apparent de-rating alongside rising earnings, Barclays says, indicates that market performance "is not just a 'Magnificent 7' story."

Monetary policy differences are another element in the bank's U.S.-overweight stance. Barclays argues the Federal Reserve has greater scope to look through energy-driven inflation than the European Central Bank, where markets continue to price in additional tightening. That policy asymmetry, the bank contends, "reinforces the gap between U.S. and European equities."

Summing up, Barclays describes the U.S. as offering the clearest mix of solid earnings growth, AI-driven capital spending, margin support and policy flexibility. The bank's guidance to investors is tactical: "lean into structural winners while hedging near-term macro and policy risks."

Risks

  • Geopolitical-driven energy shock: a surge in energy prices linked to the U.S.-Iran conflict has already dented stocks and bonds and remains a near-term risk - impacted sectors: energy, utilities, consumer discretionary.
  • Policy uncertainty in Europe: markets still expect additional ECB tightening, creating a policy asymmetry that could widen U.S.-Europe performance gaps - impacted sectors: European equities, exporters.
  • Short-term market volatility: the combination of headline risk and repricing in bond and equity markets could disrupt near-term returns, underscoring the need to hedge macro and policy risks - impacted sectors: global equities, fixed income.
