Stock Track | Corning Plummets 6.71% Intraday on Broadcom-Led Sector Selloff and Patent Ruling Loss

Stock Track06-04

Corning's stock plummeted 6.71% during Thursday's intraday trading session, marking a significant decline for the optical communications component manufacturer.

The sharp drop is attributed to a broader selloff in the optical communications sector, led by peer Broadcom. Despite posting strong quarterly results, Broadcom's CEO declined to raise the company's fiscal 2027 AI revenue guidance, creating negative sentiment that rippled across the sector and dragged down optical peers including Corning.

Compounding the pressure was a legal setback for Corning, which lost an initial ruling in a 337 investigation to Chinese manufacturer Rainbow Shares. The ruling challenges Corning's glass substrate patent moat, a key competitive advantage. Analyst sentiment also contributed to the decline, with Barclays maintaining a Hold rating on the stock with a price target of $180.00.
