Infineon stock closed at EUR 53.94 on Xetra on September 14, 2026, down 7.6 percent. The move followed a broad tech selloff in Europe, with Reuters reporting that Germany's Infineon shed 7.6 percent as AI slowdown warnings hit chipmakers.

September 14, 2026 in numbers

Infineon Technologies AG (ISIN DE0006231004) finished the session below its prior close after a volatile day. MarketScreener showed the share at EUR 53.94, with a 5-day change of -7.62 percent and a 1st Jan change of +2.47 percent, while Reuters said European shares slipped as AI caution weighed on the sector.

The stock's session move also tracked a weaker semiconductor backdrop, with Morningstar reporting that European chipmakers Infineon Technologies and STMicroelectronics were down 6.3 percent and 3.9 percent, respectively. That made Infineon's decline larger than the broader sector move.
