Company
Lumentum Holdings is a US maker of optical and photonic components, including lasers and transceivers, used in telecom, datacenter, and networking equipment.
ClearBridge added to Lumentum, Credo and Astera Labs in Q3 while the Russell 3000 Growth rose 0.5% and small-cap growth fell 9.4%. It says it used the AI volatility to broaden its tech exposure as its mid-cap growth benchmark lost 5.8%.
Reality
Lumentum says its AI data-centre optical parts are sold out until roughly 2029, with about 70% of demand for some products going unmet in 2027. Customers are paying toward the expansion, but Bloomberg reports that new optical capacity takes three to five years to build.
Reality
PicoJool, the Gelsinger-backed optics startup, raised a $27.5 million Series A to get its VCSEL links for AI data centers qualified with customers. For operators, that means a new low-power option to put through trials, with volume supply still at the planning stage.
Reality
Asked where Chuseok cash gifts should go, Korea's five largest fund houses named ten ETFs, half of them with US or global mandates, and the one fund three firms picked independently holds US dividend growers.
Reality
Kiwoom's S&P 500 Momentum ETF replaced 54 of its 99 holdings in one scheduled rebalance, putting Apple on top at 9.23%, dropping Nvidia and Broadcom, and raising Intel and AMD to 4.89% each.
Reality
The book grew from about $7bn in a year, and roughly half of it is priced by funding rounds rather than by markets, which means a demand forecast built on customer orders is partly a forecast of Nvidia's own marks.
Reality
China supplies close to 30% of some transformer and switchgear categories and more than 40% of US battery imports, so the Energy Department's new power to condition those purchases lands on a buildout planning to go from 62 GW to 152 GW.
