Marvell risks paying a peak-scarcity price for Lumentum if optical supply catches up by 2028-30. The proposed ~$99B deal values Lumentum at roughly 20x guided annualized revenue and 58x estimated after-tax operating income, while Lumentum, Coherent and Chinese suppliers are adding laser capacity. The DSP-and-laser combination has strategic logic, but durable scarcity economics and Nvidia's response remain uncertain. x.com 

Photonics stocks such as Coherent, Lumentum, Corning, Applied Optoelectronics and Ciena are priced on unknown future demand rather than current results. Lumentum's revenue has been flat, yet projections for the year ending June 2029 call for $12.8 billion, over 4x this year's $2.96 billion. That is great if true, but a lot can happen before then, especially any disruption to the data-center buildout boom. x.com 

Lumentum's 109% year-on-year growth and sold-out capacity through 2029 make selling its AI optics exposure questionable. Bloomberg reported Marvell is in advanced talks to buy it; the appeal depends on the price, especially when holders of an $80 billion Lumentum would become holders of a $320 billion-plus Marvell growing 37%. x.com 

Lumentum is a great business, but at $954 its risk/reward is not attractive. Applying 30x to fiscal 2028 non-GAAP EPS of $40 gives a 2027 price target of $1,200, about 26% upside, or roughly 15% after adjusting for execution, financial, technology and supply risks. Reaching it needs on-time manufacturing ramps, sustained pricing power and cash flow without excessive dilution. Lost pricing power plus slipping OCS or laser ramps would break the thesis; a significant dip would offer a better entry. … Show more

Optical component stocks such as Lumentum, Coherent, Applied Optoelectronics and AXT look early in an unwind, as a wave of new photonics paid newsletters signals a crowded narrative. Price pays; narratives do not. x.com 

Photonics stocks remain attractive as AI optical-component demand exceeds supply: Lumentum's CEO says the company cannot meet 70% of demand for some products through 2027 or 30% for others through 2028, with some components sold out into early 2029. The cited basket is LITE, MRVL, AAOI, COHR, SIVE and AEHR. x.com 

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  x.com 

Lumentum, AXT and Coherent face potential delays to CPO and 800V, and their charts started flopping as if the stocks knew ahead of time. Per @BULLOFBRITAIN, citing a SemiAnalysis report, CPO and 800V could be pushed back to 2028–29 while NPO potentially accelerates, with caution urged on names including Lumentum. x.com 

Lumentum's AI-optics case gains longer supply visibility: CEO Michael Hurlston says capacity is effectively sold out through early 2029 and expects roughly 70% of demand for some products to go unmet through 2027; others could face roughly 30% unmet demand through 2028. Scarcity could support pricing, but earnings growth depends on capacity expansion and yield improvements translating into shipments, revenue and margins. x.com 

Photonics stocks such as Lumentum, Coherent and Applied Optoelectronics look vulnerable because the trade is far too crowded. Today's reversal in the space could be the start of the next leg down. x.com
