STMicroelectronics Leads CAC 40, Reaching a New 5-Year High
The Franco-Italian semiconductor manufacturer opens the session with a strong increase, setting a new multi-year intraday high. The stock takes the lead in the Paris index, extending a spectacular rally that began in the spring. The announcement of a new 3D detection module aimed at embedded artificial intelligence fuels the movement.
New Five-Year Record and Confirmed Leadership on the CAC 40
STMicroelectronics stock rises 2.28% to €69.39 at the opening, leading the CAC 40, while the index itself is down 0.14%. The stock reached €69.76 during the session, a new five-year high surpassing the previous record of €69.72 set on June 3, 2026. The price is now very close to the psychologically important €70 mark. The increase coincides with the launch, announced this Monday, of the VL53L9 LiDAR module for direct 3D depth detection, intended for AI applications on compact systems. The company presents this product as a step in its strategy of integrating detection systems beyond standalone sensors. The recent momentum remains strong: about 26% over a month and 157.8% over three months, compared to a more modest gain of 2.42% over the week, indicating a consolidation phase before reaching the new high today. ASML also advanced by 1.51% and ASM International by 1.22%, in a still favorable sector environment.
Tense Technical Setup as it Approaches the €70 Threshold
The price is significantly above all its moving averages, with a gap of 8.76% over the MM20 (€63.80) and more than 120% over the MM200 (€31.47), illustrating the magnitude of the rally since spring. The RSI at 65 remains in the upper neutral zone without tipping into overt overbought territory, while the slightly negative MACD histogram (-0.10) indicates a short-term momentum fatigue, despite today's intraday high. The round €70 mark, briefly touched in the session, will be the next prospective buying signal; in case of a pullback, the recently surpassed resistance around €68.49 serves as an immediate support. In terms of valuation, according to the consensus of analysts surveyed, the stock is trading at about 61.9 times current year earnings and 31.5 times next year's earnings, multiples that reflect high expectations placed on the data center and embedded AI trajectory. Following the launch of a $1.5 billion convertible bond issue in mid-June, the potential crossing of the €70 mark will be the next observable technical milestone.
