AXT (AXTI.US) jumped **16.59%** to $113.30 leading the sector, intraday high +17.18% at $113.88; Applied Optoelectronics (AAOI.US) rose **7.52%** to $181.76, intraday high +10.67% at $187.09; Marvell Technology (MRVL.US) gained **5.06%** to $293.85, intraday high +8.12% at $302.40, holding above $300. Coherent (COHR.US) rose **4.27%** to $401.48, with intraday high of +9.23% at $420.57 before some pullback; POET Technologies (POET.US) up **4.95%** to $13.15; Corning (GLW.US) up **4.14%** to $186.62; Lumentum (LITE.US) up **2.54%** to $945.00, with intraday high of +8.35% at $998.50 before pulling back below the open. Only Nokia (NOK.US) edged down 0.95% to $14.66, diverging from the sector trend. Leveraged ETF amplification was significant — Marvell 2x bull ETF (MVLL.US) rose 10.50% to $177.85, intraday high +15.78%; AAOI derivative AAOX.US up 14.37% to $51.56, intraday high +20.74%, with single-day amplitude of ~12% reflecting strong leveraged-fund inflows. The rally reflects the "AI compute upgrade cycle driving demand for optical modules/components" narrative — the market is repricing high-speed optical interconnect demand for Nvidia's next-gen Rubin AI racks. Marvell continues to benefit from the "Trainium supply chain re-rating" narrative plus NVDA's $2 billion investment and AMD's strategic stake. AXT, as a III-V semiconductor materials supplier, benefits from upstream optical component re-rating. AAOI, Coherent, Lumentum, POET benefit from AI data center high-bandwidth optical interconnect adoption. Corning, as a fiber leader, benefits from global AI data center expansion driving high-speed fiber demand. Nokia was relatively restrained as profit-taking emerged after its previous run-up on AI network strategy + Nordic index strength. ### Related Stocks - [AAOI.US](https://longbridge.com/en/quote/AAOI.US.md) - [COHR.US](https://longbridge.com/en/quote/COHR.US.md) - [AXTI.US](https://longbridge.com/en/quote/AXTI.US.md) - [POET.US](https://longbridge.com/en/quote/POET.US.md) - [MRVL.US](https://longbridge.com/en/quote/MRVL.US.md) - [MVLL.US](https://longbridge.com/en/quote/MVLL.US.md) - [AAOX.US](https://longbridge.com/en/quote/AAOX.US.md) - [COHX.US](https://longbridge.com/en/quote/COHX.US.md) - [AXTU.US](https://longbridge.com/en/quote/AXTU.US.md) - [AXTX.US](https://longbridge.com/en/quote/AXTX.US.md) - [POEL.US](https://longbridge.com/en/quote/POEL.US.md) - [MRVU.US](https://longbridge.com/en/quote/MRVU.US.md) - [GLW.US](https://longbridge.com/en/quote/GLW.US.md) - [LITE.US](https://longbridge.com/en/quote/LITE.US.md) - [NOK.US](https://longbridge.com/en/quote/NOK.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [AMD.US](https://longbridge.com/en/quote/AMD.US.md) - [NOA3.DE](https://longbridge.com/en/quote/NOA3.DE.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) ## Related News & Research - [Marvell's AI Rally Runs Into a Price Check](https://longbridge.com/en/news/290703045.md) - [Marvell (MRVL) Buys Celestial AI And XConn As Nvidia Deepens Ties](https://longbridge.com/en/news/290685194.md) - [Focused Wealth Management Inc Takes $608,000 Position in Marvell Technology, Inc. $MRVL](https://longbridge.com/en/news/290663776.md) - [Marvell CFO Daniel Durn disposes of 2,250 common shares worth $632,272.5](https://longbridge.com/en/news/290604928.md) - [7,409 Shares in Marvell Technology, Inc. $MRVL Bought by Davis Investment Partners LLC](https://longbridge.com/en/news/290794312.md)
