New York Stock Market AI Beneficiary Stocks Plunge 13%... 5 Trillion Won Vanished in a Day

Celestica Inc. (NYSE: CLS) shares plunged 13.18% to close at $299.83 on the New York Stock Exchange on the 28th, cutting its market capitalization to about $34.4 billion (roughly ₩45 trillion). In a single day, the company lost nearly $4 billion in market value (around ₩5 trillion), with trading volume exceeding 5 million shares.

The previous day, Celestica reported fourth-quarter 2025 revenue of $3.65 billion and adjusted EPS of $1.89, outperforming both market expectations and its own guidance. Full-year revenue rose 28% year-over-year to $12.39 billion. Citing strong AI data-center demand, the company raised its 2026 outlook to $17 billion in revenue and $8.75 in adjusted EPS. It also announced plans to expand U.S. manufacturing capacity to supply next-generation AI infrastructure hardware, including Google’s TPU systems.

Headquartered in Toronto, Canada, Celestica is an electronics manufacturing service provider that supplies data-center hardware—such as servers and switches—and communications and network equipment to major global IT and cloud customers. Its stock had surged several hundred percent over the past two years amid an AI data-center investment boom. Despite strong results and outlook, analysts attribute the sharp share drop to profit-taking and renewed caution over what many saw as an overheated valuation.
