  • DAX outperformed Friday at +0.53% while the SMI and OMX Copenhagen each dropped over 0.5%, setting up a split-tone open across Europe
  • US session showed mild large-cap weakness with S&P 500 -0.17% but energy surged +1.39% on oil strength, a tailwind for Shell and BP
  • New Trump tariffs on Canada could take effect Wednesday, adding trade-risk overhang to European exporters and auto names like Stellantis

Where Europe Closed Last Session

European markets ended Friday’s session in a familiar split: Germany led while almost everything else drifted lower. The DAX 40 climbed 0.53% to 26,440, outpacing the region as industrials and autos held firm. That strength didn’t travel. The Euro STOXX 50 slipped 0.09% to 6,540, held back by broad softness across the periphery.

The FTSE 100 lost 0.21% to 10,750, weighed by miners and consumer staples. France’s CAC 40 shed 0.16% to 8,637, with luxury names giving back early gains. Italy’s FTSE MIB fell 0.20% to 53,584, and Spain’s IBEX 35 eased 0.06% to 20,157 — both unremarkable moves but enough to confirm the soggy tone outside Frankfurt.

The sharper declines came from the defensives. Switzerland’s SMI dropped 0.58% to 14,391 as pharma heavyweights Roche and Novartis pulled back. The OMX Copenhagen 25 fell 0.57% to 1,888, extending its recent weakness. The AEX in Amsterdam slipped 0.16% to 1,118. Bottom line from Friday: the DAX was a one-index rally. Today’s open needs to answer whether that German bid was a genuine rotation or a one-day anomaly.

US Overnight Snapshot

Wall Street delivered a muted session that won’t inject much energy into Tuesday’s European open. The S&P 500 dipped 0.17% and the Nasdaq Composite fell 0.28%, dragged by a 0.40% decline in the technology sector. Chip stocks did find buyers after hours on AI spending optimism — Micron and SanDisk both climbed — which could give ASML and Infineon a modest lift at the European open.

The more interesting signal came from the Russell 2000, which gained 0.52%, marking another session of small-cap outperformance. Energy was the standout sector at +1.39%, riding WTI crude’s move higher. Materials added 0.44%. Financials dipped 0.17%. The VIX fell 2.60% to 14.2 — comfortably below 15, which suggests no panic but also no conviction. For Europe, the rotation out of mega-cap tech and into energy and materials should benefit Shell, TotalEnergies, and the mining complex more than it helps SAP or ASML.

Commodity + FX Watch

Oil is the headline. WTI crude rose 1.10% to $85.40, a clear positive for BP, Shell, and TotalEnergies at the open. European energy names should trade well if Brent follows the same trajectory. Gold pushed 0.81% higher toward $4,450, which tends to support Swiss refiners and defensive positioning across the region.

Copper slipped 0.32%, a minor drag on the mining names in the FTSE 100 — Glencore and Rio Tinto may open soft. On the FX side, the yen weakened with USD/JPY rising 0.30% to 160, and AUD/USD gained 0.28% to 0.711. The stronger dollar-yen trade keeps pressure off Japanese exporters but does little for Europe directly. What matters more today is whether the euro holds its ground — any dollar strength typically compresses euro-denominated export margins for Airbus, LVMH, and the German auto sector, though it flatters their translated revenues.

What to Watch Today

  • Stellantis and the tariff overhang. New Trump tariffs on Canada could take effect as early as Wednesday. Stellantis flagged a North American turnaround snag last week, and any fresh trade escalation adds direct cost pressure to its Jeep and Ram operations. European auto names broadly — BMW, Mercedes, Volkswagen — will trade with one eye on tariff headlines all session.
  • AI spending read-through for ASML. US chip stocks rallied after hours on renewed confidence in AI capital expenditure. ASML, Europe’s highest-profile semiconductor name, should benefit from the sentiment if it carries into the cash session. Nvidia’s reported $3 billion AI infrastructure investment reinforces the demand backdrop for lithography equipment.
  • Oil-driven energy bid. With WTI above $85 and energy the top US sector overnight at +1.39%, watch Shell, BP, and TotalEnergies for early strength. If Brent crude confirms the move, the FTSE 100’s energy weighting could offset its mining drag from softer copper.
  • Swiss defensives under pressure. The SMI’s 0.58% Friday drop and continued pharma weakness suggest Zurich may lag again. Roche and Novartis need a catalyst to reverse the recent slide — neither has one on the calendar today.

Bottom Line

The setup for Tuesday leans mildly constructive but uneven. Energy names have a clear tailwind from oil strength, and the AI spending narrative gives European tech a shot at a bid — but large-cap weakness in the US and Friday’s broad softness outside the DAX suggest this won’t be a day for aggressive risk-taking. Luna3 sees a rotational session: energy and select industrials lead, defensives and pharma lag, and tariff headlines keep a lid on conviction until the Canada situation clarifies.
