@aleabitoreddit My man @yongwoonkang was predicting that Largan Precision (3008) would make a great transition from camera lenses to CPO.

$AXTI ‘s production and supply chain faced significant disruptions from Chinese export controls on InP, but recent improvements in license approvals have substantially mitigated this major risk.
Meanwhile, Japan’s JX Metals announced back in February that it plans to triple InP substrate capacity by 2030 to meet surging AI-driven optical networking demand.
The company is investing another ¥20 billion, with new capacity coming online from 2027.
InP is a critical material for optical transceivers and future photonic-electronic convergence technologies.
After multiple expansion rounds, JX Metals is clearly positioning itself as a key supplier in the AI optical infrastructure stack.
The stock has started reaction, but if a meaningful pullback comes, I may use it as an opportunity to build a position for next year.

ASE benefits from TSMC's CoWoS overflow — when TSMC can't handle demand, orders spill over to ASE. But the bigger bottleneck for 2027 isn't packaging capacity itself, it's ABF substrates (the material connecting chips to circuit boards). According to a US investment bank report, ABF substrate shortages are projected to hit 10% in H2 2026, 21% in 2027, and 42% by 2028. AI chips are the driver — each generation needs more layers and area, with top-tier AI accelerators using 15-18x more ABF than standard PC chips.
