| A genuine top-4 global optical-component IDM riding the AI interconnect wave — but it is the low-margin generalist (~8% net) trading at a specialist multiple after a 5x run, with consensus targets implying ~55% downside. Real franchise, priced for a margin structure it has never earned. | — | 1 | |
C Coherent Corpcatalyst in 43d | An II-VI/Coherent merger debt-mule reborn as the picks-and-shovels supplier of the AI-optics supercycle — backed out to 2028, Nvidia-anchored, and de-risking the balance sheet — but priced at ~49x forward EPS that already embeds flawless CPO execution it has not yet proven. | — | 1 |
| A 20-year serial cash-burner with a real PLC fab and a going-concern stamp, re-skinned as a CPO/AI-optics pure-play — the FR8 order is genuine but the balance sheet, not the technology, decides this stock. | — | 1 | |
| The cheapest, highest-margin way to own the 800G/1.6T AI-interconnect ramp — but it is a no-CIK Chinese A-share whose 47% margins, 96% offshore revenue and ~52x P/E all rest on a Broadcom-DSP / Lumentum-EML leash it doesn't own and a hyperscaler order book it can't diversify. | — | 1 | |
| A near-death epiwafer monopolist just got bought out of bankruptcy by its own customer — own the InP photonics call, not the company; the AI-optical TAM is real but the float is a recovery option on a chronically capex-starved, margin-thin foundry whose two largest customers now sit on its board. | — | 1 | |
| A genuine top-tier Chinese optics merchant (top-3 passive, #9 global components, real InP/SiPh chip + 1.6T/CPO roadmap) trapped behind a 6-year private wrapper — the only tradeable expression today is the STAR-Market IPO it has been "about to file" since 2023; not investable until the S-1 (招股书) lands, and the coverage ticker 0877.HK is the WRONG company. | — | 8 | |
| The picks-and-shovels king of the AI buildout — #1 in optical transceivers with >50% of Nvidia's wallet and the lowest forward P/E of any peer — but it is a margin-taker squeezed between US chip suppliers it cannot displace (Broadcom/Marvell DSP, Lumentum/Coherent EML) and Nvidia's own CPO/in-house ambitions, and the price already discounts flawless 1.6T execution. | — | 1 |
