European stock exchanges closed a volatile week with overall gains, driven by declining bond yields and reduced expectations of a Federal Reserve interest rate hike in October, according to Il Sole 24 ORE. Investors rotated capital out of technology equities and into defensive sectors and sovereign debt, reacting to shifting inflation data and surging crude oil prices.
The tech sector declined 3.4% across Europe, with semiconductor and hardware manufacturers absorbing heavy losses. Milan bore the brunt of the regional sell-off, finishing the week down as high-profile chip components suffered double-digit drops. Technoprobe fell 22.4%, STMicroelectronics dropped 11.6%, and Prysmian declined 11.2%, according to Il Sole 24 ORE. By contrast, defensive sectors found strong demand, pushing food and beverage stocks up by 7.6%.
Broader European indices countered the technology weakness. Paris advanced 2%, Frankfurt rose 2.1%, Amsterdam gained 1.1%, Madrid climbed 1.5%, and London added 3.1%. Safe-haven flows boosted sovereign bonds, giving US Treasuries their best weekly performance since February. The US 10-year yield retreated to 5.1% after touching highs above 5.3% that had not been seen since 2002.
Global Chip Sector Faces Worst Losing Streak Since 2008
The contraction in technology stocks extended globally, with Wall Street’s SOX semiconductor index heading toward its eighth losing session, a negative sequence not recorded since 2008, Websim reported. South Korea’s Kospi index suffered a 17% weekly loss, marking its worst weekly performance since October 2008 following an 8% single-day drop.
Market pressure on technology shares intensified amid scrutiny over debt levels at sector participants like Coreweave, coupled with variable corporate earnings reports from US banks and European luxury groups. While Cucinelli reported growth, Lvmh signaled weakness in China. Meanwhile, ASML and TSMC reported robust customer demand extending through the end of the year, with the Dutch equipment manufacturer noting that order wait times remain exceptionally extended, according to Websim.
In fixed-income markets, investor demand for safety directed 12 billion dollars into bond funds during the week. US Treasuries attracted 2.4 billion dollars, European government bonds captured 1.1 billion dollars, and money market funds experienced outflows of 53 billion dollars, Websim noted.
