Semiconductor stocks in Europe and Asia plummeted following a Wall Street sell-off, marking a significant downturn for a sector that has driven market gains this year. The Stoxx Europe 600 Technology index dropped 2.5%, with major losses for companies like ASML, Infineon Technologies, BE Semiconductor, and STMicroelectronics. In Asia, Japan’s Renesas and South Korea’s SK Hynix saw sharp declines. This sell-off reflects a broader market shift away from tech stocks due to concerns over earnings and economic slowdown. The yen's surge and expectations of US rate cuts have further impacted markets.
