Stock Track | Corning Plunges 5.42% in Pre-Market as Profit-Taking Hits Optical Communication Sector After Rapid Rally

Stock Track05-15

Corning's stock experienced a pre-market plunge of 5.42%, extending the broader pullback across the optical communication sector that has been observed this week.

The selloff reflects continued profit-taking pressure following a rapid run-up in the stock. Corning had gained over 22% in the prior five trading days and approximately 126% year-to-date, driven by strong AI data center demand and long-term supply agreements with major AI compute companies.

The current weakness is part of a broader sector correction, with optical communication and fiber optic stocks seeing notable declines after a sharp surge earlier in the week. The electronic components sector as a whole is showing broad softness amid this profit-taking activity.
