Stock Track | Applied Optoelectronics Plunges 5.28% in Pre-Market Amid Optical Communication Sector Selloff Triggered by POET Order Cancellation

Stock Track04-28 19:40

Applied Optoelectronics (AAOI) experienced a pre-market plunge of 5.28% on Tuesday, as selling pressure extended across the optical communication equipment sector.

The decline follows a broader sector rout triggered by news that POET Technologies saw its purchase orders from Celestial AI cancelled. Marvell Semiconductor, which acquired Celestial AI, issued a cancellation notice citing alleged breaches of confidentiality obligations. This development sent shockwaves through the optical communication industry, leading to continued selling pressure in the current pre-market session.

Other companies in the communication equipment sector, including Lumentum, Ciena, Arista Networks, and Nokia, were also trading lower, indicating a sector-wide risk-off sentiment. Despite Applied Optoelectronics' longer-term strategic expansion into AI data center optical modules, the stock faces heightened short-term volatility amid these industry headwinds.
