The FTSE MIB declined 1.5% to close at 52,024 on Tuesday, as a global sell-off in technology stocks weighed on investor sentiment. Semiconductor firm STMicroelectronics led the decline, plunging near 8% amid concerns over elevated valuations in artificial intelligence-related companies and renewed market volatility. The automotive sector also weakened, with losses in Ferrari (-1.5%) and Stellantis (-6.8%). Banking and insurance stocks contributed to the market's decline, led by losses in Intesa Sanpaolo (-1.5%), UniCredit (-1.5%), Assicurazioni Generali (-0.8%), BPER Banca (-0.7%) and BMPS (-0.6%). Elsewhere, Prysmian declined 4.1%. Utilities were relatively resilient, with Enel and Terna advancing on the back of lower oil prices, although Snam ended the session in negative territory.
