Semtech benefits as larger AI clusters need faster, more efficient links between GPUs and switches, which its CopperEdge and FiberEdge chips supply. Data center revenue rose 91% year over year. The stock keeps setting all-time highs despite a broad semiconductor sell-off and tops US semiconductors by Momentum Score at 99, ahead of AMD and NVIDIA. x.com 

Semtech's AI interconnect story has turned from multiple emerging bets into an explicit FY27 product stack. 800G remains durable, LPO has started shipping, ACC/CopperEdge enters production shipment this quarter, and HieFo offers a path to much higher content at 3.2T while being accretive in year one. Q1 guidance beat the Street on revenue, gross margin and EPS. The case weakens if, by summer, Semtech still cites design activity rather than measurable revenue from ACC, 1.6T FiberEdge or HieFo. … Show more

Semtech's valuation already assumes strong execution, so the stock needs growth to keep pace with a fast-expanding optical market. It is one of the few names with real products across all three AI networking layers, from scale-up copper to scale-out optics chips and, via the HieFo laser deal, scale-across. FY26 data center revenue rose 58% to $223M, with over 50% growth guided for FY27. BofA sees the optical market growing from $14B in 2025 to $73B by 2030, a pace that would ease the multiple. … Show more

Semtech is put forward as a stock to own. x.com 

Semtech is gaining share in a growing market, with content per unit about to jump and a higher-margin business left after its divestiture. FiberEdge's 800G share rose from 18% to over 50% as transceiver units roughly tripled, and it expects over 50% of 1.6T this year. Content per transceiver rises from high single digits to $80-90 as the industry moves to 3.2T in 18-24 months. Gross margin should start at 64% after the cellular module sale, versus 53% two quarters ago. x.com 

Semtech does not deserve its status as a hot optical stock, since it is mostly a low-quality analog business with only a couple of data center parts. The move has been striking, though being wrong is possible. x.com 

Semtech's low-power chips connect AI clusters and are hard to replace once designed in. The stock is breaking out, with quarterly relative performance back at highs and about 20% to go to the 1.618 Fibonacci extension. x.com 

Semtech is forming one of the strongest cup patterns in semiconductors, backed by AI data-center networking and optical connectivity exposure with accelerating revenue and EPS growth. The stock is now pushing up the right side of a massive multi-month base. x.com 

TSMC's latest results point to AI chip demand still running ahead of supply, supporting the semiconductor and equipment trade. Cantor says TSMC raised its 2026 revenue outlook again, guided December-quarter sales above consensus and held 65-67% gross-margin guidance through the N2 ramp; its bullish sector read names Nvidia, Broadcom, AMD, ASML, Applied Materials, Lam Research and KLA. Jensen Huang says AI labs need not reach trillions in revenue to justify the buildout. x.com  x.com 

Semtech benefits from Nvidia's strategy of scaling up with copper for as long as possible. At Computex 2026, Jensen Huang said to use copper wherever you can and optics only where you must. Nvidia's Blackwell NVL72 racks use thousands of copper cables rather than fiber to link GPUs within a rack, and keeping data intact over that copper relies heavily on signal-integrity chips from Semtech's active copper cable alliance. x.com
