NEW YORK, Jan 4, 2026, 19:39 ET — Market closed Western Digital (WDC) shares closed Friday up nearly 9% at $187.70, extending a sharp rally in data-storage names as 2026 began.

The burst matters because Western Digital has become a fast-moving proxy for AI-linked infrastructure spending.

NEW YORK, Jan 4, 2026, 14:01 ET — Market closed Vertiv Holdings shares jumped 8.4% on Friday after Barclays upgraded the industrial stock to overweight and lifted its price target to $200. “The recent selloff in the shares creates an attractive entry point,” Barclays analyst Julian Mitchell wrote.
