The CAC 40 rose 0.9% to close at 8,327 on Thursday, rebounding from a near one-month low in the previous session as gains in technology, luxury, and financial stocks lifted the index.
STMicroelectronics surged 7.1%, supported by strong sentiment across the semiconductor sector after demand for SK Hynix's US share offering exceeded available shares by more than sevenfold.
The company also projected second-quarter revenue of about $3.45 billion and a gross margin of roughly 34.8%, signaling solid growth momentum.
Luxury stocks also advanced, with LVMH rising 1.6% and Hermès gaining 3.6%.
Financials added to the rally, as BNP Paribas climbed 1.3%, Crédit Agricole rose 1.2%, and Société Générale advanced 3.2%.
