AAOI (AAOI.US) led the downturn, falling **11%** to $111.16 and hitting an intraday low of $106.10. Marvell (MRVL.US) dropped **7%** to $206.22, while Lumentum (LITE.US) declined **7%** to $755.93. Axcelis Technologies (AXTI.US) slipped **7%** to $53.61, Corning (GLW.US) fell **7%** to $175.33, and Coherent (COHR.US) decreased **4%** to $298.53. Nokia (NOK.US) lost **4%** to $11.20, and POET (POET.US) dropped **4%** to $8.42. Among derivative ETFs, AAOX plunged over 22%, MVLL fell nearly 15%, LITX dropped more than 14%, while LITZ bucked the trend with a nearly 15% gain. On the trading front, the optical communication sector faced broad profit-taking pressure. Earlier rallies driven by AI infrastructure demand had pushed optical module concepts to elevated levels, leaving the sector vulnerable to a pullback. Today's market sentiment turned cautious as capital rotated out of high-flying technology names. Analysts note that while the long-term investment thesis for AI infrastructure remains intact, near-term valuation concerns prompted investors to lock in gains. ### Related Stocks - [LITE.US](https://longbridge.com/en/quote/LITE.US.md) - [AXTI.US](https://longbridge.com/en/quote/AXTI.US.md) - [GLW.US](https://longbridge.com/en/quote/GLW.US.md) - [COHR.US](https://longbridge.com/en/quote/COHR.US.md) - [MRVL.US](https://longbridge.com/en/quote/MRVL.US.md) - [NOK.US](https://longbridge.com/en/quote/NOK.US.md) - [AAOI.US](https://longbridge.com/en/quote/AAOI.US.md) - [POET.US](https://longbridge.com/en/quote/POET.US.md) ## Related News & Research - [HighTower Advisors LLC Cuts Position in Corning Incorporated $GLW](https://longbridge.com/en/news/298285659.md) - [Corning (NYSE:GLW) Earns Buy Rating from Analysts at China Renaissance](https://longbridge.com/en/news/298317168.md) - [3 Stocks Riding The Smart Glasses And Eye Care Shift Investors Should Watch](https://longbridge.com/en/news/298212746.md) - [Concurrent Investment Advisors LLC Grows Position in Corning Incorporated $GLW](https://longbridge.com/en/news/298101680.md) - [Corning Incorporated $GLW Shares Sold by HB Wealth Management LLC](https://longbridge.com/en/news/298127085.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
