Infineon Technologies is trading 8.78% up now at €64.64, with the move pointing more to semiconductor-sector momentum than to a fresh company-specific trigger. - Reports around the October 2 session linked the earlier rally to Micron’s strong results and AI-driven sector optimism. - Infineon’s AI revenue growth and Bangkok factory opening also reinforced the positive outlook. - Reporting does not establish a fresh October 5 company-specific announcement as the direct cause; provided market context shows no index move above 0.5%.
