European stocks gain on ASML sales forecast; U.S. CPI test awaited

European equity markets experienced a positive shift on Wednesday, buoyed by a robust fourth-quarter sales forecast from leading semiconductor lithography company ASML. The firm's outlook reignited investor interest in technology stocks, enabling continental indices to weather cautious remarks from the European Central Bank (ECB).

The Stoxx Europe 600 Index climbed 0.35%, while Germany's DAX and France's CAC 40 both increased by 0.5% each, whereas London's FTSE 100 edged higher by 0.1%. ASML, in particular, saw a 1.6% rise following the Veldhoven-based firm's projection of fourth-quarter net sales exceeding market expectations, driven by persistent demand for its cutting-edge lithography tools, spurred by global AI datacenter growth.

Despite ASML narrowing its full-year 2026 sales outlook, analysts were encouraged by strong Q4 bookings and capital expenditure in AI infrastructure, which lifted other semiconductor-related stocks, including ASM International (+1.5%), BE Semiconductor (+0.8%), and Infineon Technologies (+1.6%). The tech sector's rally helped continental indices maintain focus on underlying strength, rather than ECB President Christine Lagarde's comments.

Lagarde, speaking at the IMF and World Bank meetings, downplayed the likelihood of the central bank providing emergency tools to support European sovereign debt, urging French lawmakers to resolve their fiscal issues through domestic consolidation. While investors appreciated the intraday gains, broader portfolio positions were maintained with caution, awaiting the forthcoming U.S. Consumer Price Index (CPI) report.

With 10-year Treasury yields nearing multi-decade highs above 5.20%, macro investors will closely scrutinize the inflation data for hints on the Federal Reserve's possible rate hike during their October policy meeting. A more aggressive-than-anticipated CPI figure could challenge the valuation of global growth stocks.
