European equities finished Tuesday's session in negative territory, surrendering an early advance as investors balanced a surge in global bond yields against fresh optimism over artificial intelligence capital expenditure. The pan-European STOXX 600 declined 0.1%, having been up as much as 0.7% intraday.
Regional benchmarks were mixed but mostly softer. Germany's DAX closed roughly flat, while France's CAC 40 and London's FTSE 100 each shed about 0.5%.
Chipmakers shine on Anthropic disclosure
Semiconductor and technology shares provided the clearest support before the broader market rolled over. A Reuters report indicating that Anthropic's IPO prospectus points to a substantial step-up in cloud, computing and infrastructure spending lifted chip names on both sides of the Atlantic.
In Paris, X-Fab Silicon Foundries advanced 7.5%. ams OSRAM added 8.7% and Technoprobe rose 6.8% in Milan. German listings were strong: Infineon Technologies climbed 4.8%, Aixtron gained 4.3% and Siltronic jumped 7.17%. Amsterdam-listed ASML Holding rose 4.18%, ASM International added 4.24% and BE Semiconductor Industries gained 4.42%. STMicroelectronics rose 2.6% and Soitec gained 9.08%. In Vienna, AT&S added 7.18%, while Brussels-listed Melexis rose 3.8%.
French infrastructure names slide on tax plan
Eiffage fell 3% and Vinci dropped 2.4% after the French government proposed a significant increase in the tax on motorway concessions and major airports, a move that would directly affect the two companies' concession businesses.
Lindt & Sprüngli tumbled 8% after the Swiss chocolate maker cut its full-year organic sales growth forecast for the second time this year, citing subdued consumer sentiment and weak demand.
Julius Baer shares rose 7.2% after Switzerland's financial regulator FINMA closed enforcement proceedings related to private debt loans and the bank's client relationships with two Russian politically exposed individuals. Legrand gained 6% after the French electrical and digital building infrastructure group raised its medium-term targets.
September losses snap six-month winning streak
The month's declines have ended a six-month winning run for the STOXX 600, which is down nearly 2% in September and on course for its first monthly drop since March. Equities have been volatile throughout the month, pressured as sovereign bond yields touched their highest levels since the 2008 global financial crisis.
A fresh European Central Bank rate hike, persistent hawkish commentary from central bank policymakers, and warnings from AI industry figures about a potential development slowdown have all contributed to the selling pressure. Rising sovereign yields serve as the benchmark for pricing riskier assets; as they climb, the discount rate applied to future corporate earnings expands, compressing equity valuations.
Middle East standoff keeps energy prices elevated
A brief prospect of a diplomatic breakthrough in the Middle East flared and quickly faded earlier this month, adding to investor fatigue. Markets have effectively settled into a standoff following a sharp exchange of rhetoric between President Trump and Iranian leadership over the Strait of Hormuz. With diplomacy stalled and military posture still tense, elevated energy prices continue to limit any broader relief rally in rate-sensitive sectors.
