1515 ET [Dow Jones]--Five data center companies who got their start in the cryptocurrency mining business are set up for "rapid growth," UBS analysts write in a note, initiating coverage of the stocks with buy ratings. The companies -- Hut 8, TeraWulf, Core Scientific, Cipher Digital, and Applied Digital -- already have connections to power grids that will prove increasingly valuable, given that "time to power is the key factor in data center development," the analysts write. "They occupy the enviable position of right place, right time with the skills and assets to supply crucial inputs in the largest infrastructure spending project in history."
