Europe Just Beat the S&P 500 by Its Widest Weekly Margin Since March. Follow the Money.

The Stoxx Europe 600 is on course this week for its biggest outperformance over the S&P 500 since March, and the catalyst is not obscure. European stocks rose, headed for their biggest weekly outperformance over the S&P 500 since March, as the region benefits from a switch among investors out of the AI trade and from some positive earnings news. That combination of a stumbling US growth trade and strengthening European fundamentals is precisely the kind of structural inflection worth tracking with discipline rather than dismissing as noise.

The US side of the ledger is telling. The S&P 500 and the Nasdaq marked their biggest one-day fall since July on Wednesday after hotter-than-expected consumer inflation data fueled expectations of further interest-rate hikes from the US Federal Reserve, dragging on tech stocks. Semiconductor maker TSMC’s cautious note for 2027, citing macroeconomic uncertainties, also dented sentiment. The pressure intensified Thursday: tech stocks fell with Nvidia down 2.5%, Intel over 6%, SpaceX over 5%, Micron 4%, Dell over 9% and Broadcom 2.5%. After trading at all-time highs just one week ago, the S&P 500 was off 1% from its week-ago record, while the tech-heavy Nasdaq had fallen more than 3% below its peak.

Europe absorbed relatively little of that damage. The Stoxx 600 rose 0.3% to 641.75 points by early Friday morning and was up more than 1% for the week. Robust earnings from European firms helped steady markets at the end of a volatile week marked by a selloff in high-flying tech names on concerns over Chinese competition and increased debt funding to develop AI infrastructure. The dispersion is the point: the indices that carry the least AI weight absorbed the least AI pain.

The earnings backdrop reinforces the case. Barclays strategists expect European earnings to have jumped 21% in the third quarter, partly boosted by a weaker euro, with the team led by Emmanuel Cau noting that “resilient hard data and positive pre-announcements suggest third-quarter estimates remain within reach and beats are likely.” Morgan Stanley raised its MSCI Europe target to 2,840 for June 2027, implying about 12% upside, citing stronger earnings-per-share growth. Early reporters are already delivering. Schneider Electric raised its 2026 core profit and revenue targets for the second time this year, with third-quarter revenue growing 16.9% organically to €11.46 billion, beating analysts’ average forecast of €11.13 billion.

The structural argument for Europe is also cleaner than the headlines suggest. European equities appear well-positioned to capture reflationary tailwinds given their cheaper valuation, lower crowding and easier earnings comparisons, without being overly dependent on the fate of the AI trade. The concentration risk that defines US large-cap exposure simply does not exist in the same form across the Atlantic. The largest ten companies in the US make up about 40% of the index; in Europe, the top ten companies make up just 15% of total index market capitalisation.

The honest risk: this move is partly defensive, not purely fundamental. When US rates rise and AI spending is questioned, capital rotates toward whatever carries less exposure, not necessarily toward whatever is most attractive on its own merits. Barclays sees the pace of earnings upgrades easing into 2027, writing that a “peaking growth impulse, tougher base effects and fading energy tailwinds point to a moderation in earnings momentum.” France’s fiscal position remains a live concern. The FTSE 100’s outperformance this week looks solid; the broader case requires monitoring the earnings season now underway.

The allocation call: treat this as a real rotation worth building, not a short-term flight to safety to fade. Barclays strategists indicated that if the earnings season for the Stoxx Europe 600 constituents exceeds expectations, European value stocks, growth stocks, and small-cap stocks could see significant benefits. Industrials and financials are the sectors showing leadership. Position in broad European exposure through the Stoxx 600 or DAX, watch the earnings flow over the next three weeks for confirmation, and set a clear stop below the pre-breakout consolidation. If the AI-rate pressure in the US deepens, this gap widens further. If the Fed pivots or AI capex fears ease, the relative trade compresses fast.
