CAC 40 Under Pressure: Construction Declines, STMicro Soars Amid Ormuz Tensions Easing

A Parisian Trading Session Influenced by Geopolitics

The announced easing between Washington and Tehran over the Strait of Hormuz sets the backdrop for the European session. After several days of escalation, the two capitals have agreed to pause strikes and resume technical discussions on reopening the energy corridor to commercial traffic. This relative détente limits the risk premium on oil, even though Brent crude remains around $72.50 per barrel and tanker security remains a key concern.

Other major European markets show a trend close to equilibrium: the DAX is up 0.05% in Frankfurt, the FTSE 100 is down 0.19% in London, and the STOXX 600 declines by 0.03%. In Paris, the session is selective, with the technology sector in demand, while major construction and luxury stocks are distinctly out of favor. In the background, Asia closed mixed, with the Hang Seng rising by 1.57% at the close and the Nikkei 225 up by 0.15%.

STMicro and tech drive the few gains

Leading the CAC 40, STMicroelectronics jumps by 3.6% to 64.83 euros, driven by a significant upward revision of target prices from brokers: HSBC, with a buy rating, increases its target from 53 to 84 euros, while JP Morgan, with a neutral rating, adjusts its from 48 to 71.50 euros. The French-Italian semiconductor company significantly dominates the midday rankings.

Following behind, the technology sector and services are also on the rise: Dassault Systèmes advances by 1.78% to 18.25 euros, Publicis Groupe gains 1.45% to 87.88 euros, and Capgemini climbs 0.89% to 90.48 euros. Thales rounds out the top five with an increase of 0.88% to 218.40 euros, benefiting from an initiation of coverage with an « overweight » rating by Oxcap Analytics, with a target set at 325 euros.

Concessions, Construction, and Luxury Sectors See Significant Decline

The bottom of the leaderboard is dominated by players in infrastructure and construction. Vinci dropped 2.81% to 126.45 euros, followed by Eiffage, down 2.42% to 127.05 euros. Bouygues fell 2.23% to 48.64 euros and Saint-Gobain lost 2.03% to 78.96 euros. The sector, sensitive to macroeconomic expectations and long-term interest rates, bears the brunt of the day's sharpest declines.

In the luxury sector, EssilorLuxottica fell 2.31% to 164.75 euros. The stock remains affected by target adjustments: HSBC, while maintaining a buy rating, lowered its target from 340 to 200 euros, while Goldman Sachs cut its target from 260 to 230 euros, also retaining a buy rating. Overall, the Paris session illustrates investors' mixed reading: a geopolitical respite benefiting certain global cyclical segments, yet lingering caution regarding domestic stocks most exposed to the investment cycle.
