Infineon Takes the Heaviest Blow as a Rival’s Cautious Outlook Rattles European Chip Stocks
Published on 07/24/2026 at 13:51 | Redaktion boerse-global.de
For a company that had nothing new to report on Friday, Infineon found itself squarely in the crosshairs of a sector-wide selloff triggered by events thousands of kilometres away. The German chipmaker’s shares slid 6.64 percent on Thursday, closing at €65.25, making it the worst performer in the DAX. The culprit? A disappointing revenue forecast from Franco-Italian rival STMicroelectronics that sent shockwaves through the semiconductor industry.
STMicroelectronics cut its third-quarter revenue guidance to $3.7 billion, falling short of the $3.8 billion analysts had pencilled in. The market reaction was brutal — shares in the Paris-listed company plunged as much as 17 percent at one point, hitting their lowest level since mid-May. The selloff quickly infected other European chip stocks, with BE Semiconductor, Melexis and Infineon all taking hits in early trading.
The irony is that STMicro’s underlying business performance was actually solid. Second-quarter revenue climbed 26 percent year-on-year to nearly $3.5 billion, slightly ahead of the $3.51 billion consensus estimate. But that wasn’t enough to shield the stock from the harsh judgement of investors who had pushed valuations higher during the sector’s recent rally.
Jefferies analyst Janardan Menon offered a potential explanation for the cautious outlook: production of the iPhone 18 may be ramping up more slowly than anticipated. That observation acted as a warning flare for the entire supply chain, since smartphone manufacturing delays often ripple across multiple chip suppliers simultaneously.
Should investors sell immediately? Or is it worth buying Infineon?
Adding to the pressure was Texas Instruments, the US chipmaker that reported second-quarter results that actually beat expectations. Revenue came in at $5.46 billion, while earnings per share of $2.14 topped forecasts. The third-quarter guidance was also optimistic, with revenue expected between $5.65 billion and $6.15 billion and EPS in the range of $2.23 to $2.57. Yet investors sold the stock in after-hours trading anyway, suggesting that even a solid beat wasn’t enough to satisfy a market that had already priced in strong performance.
The nervousness spread to European names like Infineon, which shares many of the same end markets — particularly automotive and industrial. Both STMicro and Texas Instruments serve these sectors, making Infineon especially vulnerable to sentiment shifts among its peers.
Despite Thursday’s drubbing, Infineon’s year-to-date performance remains impressive at roughly 73 percent in the black. But the stock has now fallen 27 percent from its 52-week high of €89.67, hit on June 3. The pullback suggests that some of the earlier gains may have run ahead of the underlying business fundamentals.
Chart watchers see a fragile picture. The relative strength index sits at 40.1, a neutral reading that offers little directional clarity. A sustained breakout above previous resistance levels has yet to materialise, leaving the current recovery looking more like a countermove within a short-term downtrend.
Analysts remain broadly positive on Infineon’s structural strengths, but the market’s focus has shifted to valuation. After such a steep rally, investors are scrutinising price-to-earnings ratios more closely and punishing any whiff of disappointment.
Infineon at a turning point? This analysis reveals what investors need to know now.
The next major test for Infineon comes on August 5, 2026, when the company reports its fiscal third-quarter results. Management has sounded upbeat, forecasting revenue of around €4.1 billion based on an assumed euro-dollar exchange rate of 1.17. Alongside the top line and margins, investors will be watching order intake, cash flow and the forward guidance for clues about whether the company can avoid the same fate as STMicro.
The parallel is hard to ignore. STMicro delivered a fundamentally sound quarter and still got punished because expectations had run too high. Infineon shareholders will be hoping history doesn’t repeat itself.
