Euro STOXX 600 Gains 9.7% in Q1, Marking Strongest Quarterly Performance Since October 2020
Claire Weston
The pan-European STOXX 600 rose 9.7% in Q2 — its strongest quarter in nearly four years — driven by AI-fueled tech gains, with easing Middle East tensions and lower oil prices adding support.
How strong was this rally?
The STOXX 600 closed at 639.77 on June 30, up 0.6% on the day and 9.7% for the quarter.
That marks the best single quarter since October 2020 and a third consecutive monthly gain.
This means → European equities are not bouncing — they have sustained a three-month uptrend.
What drove the gains?
Tech stocks led. Europe's tech sector posted its highest quarterly gain since October 2001.
ASML rose 3.33%, STMicroelectronics gained about 3%, and Infineon added roughly 2.7% — all lifted by expectations of expanding AI infrastructure spending.
In plain terms = as long as markets believe "building AI means buying more chips and equipment," European chipmakers ride the wave.
Notably, European tech outperformed its U.S. counterpart both for the month and the quarter — a rare occurrence in recent years.
What else contributed beyond tech?
Siemens Energy rose about 5% after reaffirming strong demand for AI-related equipment on its quarterly earnings call.
This means → AI's pull extends beyond chips into power infrastructure.
Easing Middle East tensions also mattered: oil prices fell back to pre-Iran-conflict levels, reducing energy cost pressure on the European economy.
Any standout in healthcare?
Abivax surged over 20% after reporting positive top-line data for obefazimod — an anti-inflammatory drug in development.
The broader healthcare sector rose 0.9%, a modest but directionally consistent gain.
What to watch next quarter?
The key test is whether tech can deliver earnings that match the AI capital-expenditure cycle's promise.
In plain terms = markets have already priced in "AI will be big." The next step is whether corporate results actually meet those expectations.
If earnings fall short, valuations inflated by forward expectations face correction risk.
