$ATEYY
advantest3/10Does he own it?
No first-person buying, holding, adding, or sizing language anywhere. ATEYY appears only as one name among a dozen in CPO/silicon-photonics ecosystem lists. He muses that an equal-weighted ecosystem long "might not be a bad idea" but never states he took a position or disclosed any weight. Pure coverage of a large-cap testing name.
His thesis
ATEYY is framed as a key beneficiary of the silicon-photonics / co-packaged-optics buildout, specifically on the testing side of the bottleneck (optical alignment, qualification cycles). He groups it with other testing names like KEYS, and ties it to the Global Foundries photonics/CPO ecosystem and the expected ramp where SiPh modules exceed half of data-center transceiver sales by 2026. Mildly positive on the whole basket rather than singling ATEYY out.
How his view evolved
Brief, consistent thread over two weeks in April 2026. Started naming ATEYY as a testing/optical-alignment play, then folded it into a broader GFS photonics ecosystem ticker list with a passing "equal-weight the basket" idea. No deepening conviction or position-building.
Key points
- Cast as a testing/optical-alignment beneficiary of the CPO and silicon-photonics bottleneck
- Appears only inside multi-name ecosystem lists, never singled out
- Floats an equal-weighted ecosystem long but never states an actual position or weight
