| 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. | — | 8 | |
Q Quantum Computing Inccatalyst in 44d | A $2.5B market cap on $682K of FY25 revenue — QUBT is a $1.5B treasury wrapped in a photonics R&D lab, sold as a quantum-computing story; the balance sheet is real, the revenue is not, and a securities-fraud class action over the exact gap between the two is unresolved. | — | 8 |
| 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 | |
| A re-rated telecom-equipment turnaround wearing an AI-infrastructure mask — the optical/AI-RAN engine is real and accelerating, but the stock already prices the re-rating (P/E ~90, +109% in 12m) while ~92% of revenue is still slow-growth telecom/IP/patents. Right business, wrong entry. | — | 8 | |
| The arms-dealer of the AI optics build-out — Lumentum owns ~50-60% of the 200G/lane EML laser chip that every 1.6T transceiver needs, NVIDIA just bought $2B of preferred to lock its capacity, and revenue is compounding ~90% YoY off a real telecom trough; but at ~52x forward earnings with two customers = ~40% of revenue and a $3.8B convertible stack now in-the-money, the price already discounts flawless execution. | — | 8 | |
L Lightwave Logiccatalyst in 44d | A 35-year science project that just turned the corner from lab to foundry PDK — credible polymer-photonics platform now inside Tower & GlobalFoundries flows, but $237K of revenue against a $1.5B cap means you are buying a 2027-28 design-win option, financed by perpetual dilution, with a 17.7% short base betting it stays a promise. | — | |
| 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. | — | 8 | |
| The unglamorous AI-optics toll-collector — a 12%-gross-margin Thai contract manufacturer the market is now paying a 45× fabless multiple for; the business is genuinely inflecting (DCI +90%, 1.6T capacity doubling) but the price has front-run two years of execution AND ignores that co-packaged optics is a 2027+ structural axe over the whole pluggable-transceiver thesis. | — | 8 | |
| 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. | — | 8 | |
| 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. | — | 8 | |
| A real moat in AEC reliability and an n-1 cost edge, riding a verticalizing AI-interconnect ramp — but ~84% of revenue sits in three hyperscalers and ~41x forward earnings already prices in the optical pivot working. Bullish business, expensive stock; conviction gated on customer diversification proving out. | — | 8 | |
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. | — | 0 |
| A real, scarce, China-gated InP asset that AI-optics demand made strategic — but the stock already priced an ~80x melt-up to a ~$5.9B cap on an $88M-revenue, loss-making, single-country-manufacturing base; the asset is genuine, the multiple is a dare. | — | 8 | |
| 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. | — | 8 |
