As of April 06, 2026 The AI Photonics & Optical Infrastructure sector is showing a sharply divided session, led by a massive surge in $AEHR (+17.69%). The stock broke above key resistance and hit (benzinga.com/markets/tech/2…) a new 52-week high as traders piled in ahead of tomorrow's Q3 earnings report (April 7 after close), stacking on top of last week's new silicon photonics customer win for FOX-XP/FOX-NP wafer-level burn-in systems destined for hyperscale data center transceivers (benzinga.com/markets/tech/2…). The broader sector is caught between two forces today: the structural AI data center buildout narrative keeps rewarding names tied to the 800G-to-1.6T transceiver migration and SiPho testing infrastructure, while $AXTI got hammered on a proposal to raise authorized common shares from 70 million to 120 million ahead of its May 14 annual meeting, spooking investors with dilution risk even as the company plans to double InP manufacturing capacity Yahoo Finance. The result is a bifurcated tape where upstream substrate plays are bleeding and downstream equipment/transceiver names are holding or rallying. $AEHR: +17.69% $AAOI: +3.41% $LWLG: +2.74% $MRVL: +2.24% $FPLSF: +1.43% $FORM: +1.27% $KEYS: +0.58% $BESIY: +0.34% $GFS: -0.32% $POET: -0.49% $FN: -0.65% $GLW: -0.96% $COHR: -1.91% $CIEN: -3.02% $TSEM: -3.85% $SIVEF: -4.63% $SOI: -5.80% $IQE: -5.98% $LITE: -6.60% $SIVE: -11.21% $ALMU: -12.69% $AXTI: -20.53% 1. Optical Transceivers & Active Networking AAOI, LITE, CIEN, COHR, FN, GLW: Mixed action across the transceiver and optical networking complex. AAOI continues to outperform on its 800G/1.6T hyperscaler order momentum and domestic manufacturing tailwind, while LITE gave back hard despite its Nvidia strategic investment backing. CIEN and COHR are fading, possibly on profit-taking after recent runs. FN and GLW are soft but holding relatively tight. 2. Compound Semiconductor Substrates & Foundries AXTI, TSEM, GFS, IQE, SOI: Brutal day for substrate names. AXTI cratered 20% on the share authorization expansion proposal, which the market is reading as a dilution setup even though the stated purpose is funding InP capacity buildout for the AI optical cycle. IQE and SOI continue to leak on thin OTC liquidity and persistent float overhang concerns. TSEM is pulling back in sympathy. GFS is basically flat. 3. Early-Stage Photonic Materials & PICs POET, LWLG, ALMU, SIVEF, SIVE, FPLSF, BESIY: LWLG is the standout gainer in this group on continued EO polymer interest. The OTC micro-cap names (SIVE, ALMU, SIVEF) are getting crushed on what looks like liquidity-driven selling rather than any thesis-specific deterioration. POET is flat-ish and treading water. FPLSF and BESIY are holding up. 4. Semiconductor Equipment, Test & Infrastructure AEHR, FORM, KEYS, MRVL: AEHR is the clear story of the day, ripping into earnings on the back of its SiPho customer win and pre-report momentum buying. Up 158% YTD and still running. MRVL is catching a bid on broader AI semi sentiment. FORM and KEYS are green but quiet.
