AI fatigue: Citi cuts U.S. and tech to neutral, turns bullish on Europe

Citi downgraded U.S. equities, global tech and European tech to Neutral from Overweight, warning Nasdaq positioning could turn net short after a further 5% decline; it upgraded European equities outside the U.K. to Overweight. The bank cited weaker AI sentiment, wider credit spreads and slower earnings revisions, while noting lower oil prices and bond yields and resilient economic data. Citi expects global earnings growth to slow by about 20 percentage points in 2027, and says global stocks rose about 4% on average in comparable years, with defensive and high-quality shares outperforming.

Analysis

This is a positioning warning, not a clean signal to short technology. If Nasdaq exposure is already near neutral, further de-risking could create a sharp but temporary squeeze; the more durable concern is whether weaker AI sentiment translates into lower capex expectations and downward earnings revisions. Watch semiconductor, cloud, and data-center supply-chain guidance—not sentiment alone—for confirmation. Citi’s 2027 earnings-growth outlook is a forecast, not a verified earnings inflection.

Relative exposure looks more actionable than a broad risk-off bet. Europe ex-U.K. may benefit from lower oil and less direct technology concentration, but a slowing global earnings backdrop could still pressure export-sensitive cyclicals and materials. Healthcare offers a cleaner defensive expression; materials and food and beverage are more exposed to commodity, China-demand, and input-cost reversals. Falling bond yields support duration-sensitive equities, while widening credit spreads are a counter-signal that argues against assuming an uncomplicated rotation into European cyclicals.

Near term (days to weeks), positioning-driven volatility cuts both ways and can reverse quickly. Over 1–3 months, the key tests are AI-related earnings revisions, credit spreads, and whether oil and yields remain lower. Over 6–18 months, sustained AI-spending cuts would threaten the investment chain well beyond chipmakers; stable spending and revisions would invalidate the underweight thesis. The article offers no company-specific catalyst for Citigroup (C); do not treat the bank’s market call as a fundamental signal on its own shares.

Key Decisions for Investors

• Prefer a modest, beta-aware relative-value position: long Europe ex-U.K. equities (for example, EZU) versus U.S. technology (for example, XLK), rather than an outright equity short. Stage entry and keep the position small given squeeze risk; reduce or exit if European earnings revisions deteriorate relative to U.S. tech or oil reverses higher.
• Within Europe, favor healthcare over materials as the more defensive expression of slowing earnings growth. Treat any materials overweight as conditional on evidence of resilient global demand, not simply lower oil prices.
• Avoid adding to an AI/technology underweight solely on sentiment. Reassess after the next round of hyperscaler and semiconductor guidance: stable capex plans and improving EPS revisions, alongside tighter credit spreads, would falsify the cautious thesis and favor covering shorts.
• Track Nasdaq positioning, AI-linked earnings revisions, credit spreads, oil, and bond yields as the decision dashboard. A further positioning washout without estimate cuts could be a contrarian entry signal; estimate reductions plus persistent spread widening would favor maintaining relative underweights.
• No standalone trade in Citigroup (C) is supported by this market-strategy article; verify company-specific earnings, credit, and capital signals before making a stock-level decision.
