AI data center infrastructure stocks have lost $4.2 trillion in market value since June, nearly erasing half of the $9.4 trillion gained over the previous 12 months. According to PANews, a Financial Times analysis reported on November 15, the losses have affected manufacturers, utilities and mining companies supplying the data center buildout as investors question the sustainability of the AI boom.
The selloff in technology stocks and concerns about slower data center expansion have weighed on suppliers. HVAC installer Comfort Systems USA (FIX) and fiber-optic manufacturer Corning (GLW) have each fallen by about half from previous peaks, while motion-control products maker Allient (ALNT) is down 35% from its record high in October.
