Optics Stocks Drop on Anthropic News, WSJ Report: Lumentum Down 10%, Corning Down 8%, AXT Down 12%
Optics stocks fell sharply as Anthropic's revenue missed expectations and rising interest rates spooked investors. Lumentum (LITE) dropped 10%, Corning (GLW) 8%, and AXT (AXTI) 12%. Fabrinet (FN) fell 20% despite record revenue, with investors viewing guidance as conservative. Lumentum and AXT are up significantly year-to-date, while Corning is up 98%.
How this was made

The 30-second read
Why it matters
Traders are likely treating the catalyst as a broad risk-off signal for AI hardware supply chains, with additional post-earnings guidance conservatism cited for Fabrinet.
Market read
This is a same-session, catalyst-driven de-risking story for optics/AI hardware names, with FN also having a guidance interpretation component.
What to watch
If the 30-year yield reverses, the group could snap back quickly given the large recent run-ups cited for LITE, AXT, and GLW.
Background
The piece links today’s optics weakness to Anthropic ARR coming in below Silicon Valley whisper figures, plus a WSJ analysis of ballooning AI-related off-balance-sheet commitments and a jump in the 30-year Treasury yield.
Ticker impact
Lumentum shares are down about 10% after the article links risk-off selling to Anthropic ARR missing whisper figures.
Choppy to lower intraday, with stabilization possible if 30-year yields ease.
The article attributes the move to a broad risk-off rotation rather than new Lumentum-specific fundamentals, but it still cites Lumentum’s same-day drawdown.
AXT is cited as down roughly 12% as investors rotate out of AI hardware names following Anthropic ARR disappointment.
Further pullback possible if yields keep rising; otherwise mean reversion risk increases.
The text emphasizes profit-taking after a strong run and ties today’s weakness to the same macro catalyst.
Corning is reported down about 8% in the same risk-off wave hitting optics supply-chain stocks.
Likely underperforms while the group de-risks; could rebound if the 30-year selloff pauses.
The article provides no new GLW-specific disclosure, only group-level price action and macro/rates context.
Fabrinet is described as down around 20% despite record Q4 revenue and a guidance range that investors view as conservative.
Downward bias may persist until investors re-rate the conservatism in guidance.
Unlike the others, the article includes concrete Q4 results and Q1 2027 guidance, framing the selloff as guidance conservatism.
Market effects
Optics and AI hardware suppliers are trading as a rates-sensitive, positioning-heavy complex after Anthropic ARR undershoots whispers.
US-focused selloff in S&P 500 optics/semis names during the session.
Global AI infrastructure capex expectations may be repriced if off-balance-sheet commitments and rates fears dominate sentiment.
Counterpoint
The article claims optics fundamentals are unchanged, so the selloff may be an overreaction to macro headlines and profit-taking rather than a demand break.
