To The Moon

Trump's proposed ban on Chinese optical transceivers ignited one of the strongest rallies the optical networking and AI hardware sector has seen this year.

The move fueled broad buying across companies tied to optical components, photonics, semiconductor equipment, networking, and AI infrastructure.

Biggest winners included:

• $Silver Verde May Mining Co., Inc.(SIVE)$ +20.33%

• $Applied Optoelectronics(AAOI)$ +17.31%

• $Lightwave Logic, Inc.(LWLG)$ +13.49%

• $Fabrinet(FN)$ +13.27%

• $Coherent(COHR)$ +12.53%

• $POET Technologies Inc(POET)$ +12.09%

• $Aehr Test(AEHR)$ +11.96%

• $Marvell Technology(MRVL)$ +10.42%

• $Wolfspeed Inc.(WOLF)$ +9.51%

• $Teradyne(TER)$ +9.58%

The rally quickly broadened across the entire optical supply chain:

• $Lumentum(LITE)$ +6.38%

• $Credo Technology Group Holding Ltd(CRDO)$ +6.68%

• $Ciena(CIEN)$ +5.33%

• $MACOM Technology Solutions Holdings, Inc.(MTSI)$ +4.40%

• $Viavi Solutions(VIAV)$ +6.23%

• $Semtech(SMTC)$ +6.31%

• $LightPath(LPTH)$ +8.68%

• $nLIGHT(LASR)$ +8.15%

Semiconductor manufacturing and testing names also joined the move:

• $Amkor Technology(AMKR)$ +7.75%

• $FormFactor(FORM)$ +7.67%

• $Onto Innovation Inc.(ONTO)$ +6.86%

• $Lam Research(LRCX)$ +5.14%

• $Applied Materials(AMAT)$ +4.15%

• $Cohu(COHU)$ +4.86%

• $Veeco Instruments(VECO)$ +4.57%

• $STMicroelectronics NV(STM)$ +3.97%

The market's message was clear: if restrictions reduce reliance on Chinese optical transceivers, capital is likely to rotate toward Western suppliers across the AI networking ecosystem.

Whether the proposal ultimately becomes policy remains to be seen, but today's price action highlights how strategically important optical networking has become in the AI infrastructure buildout.
