I’ve actually entered positions in many tiny Korean companies recently… That actively supply memory, test, machines, etc. to $MU, $SKHY, Samsung, and others like $SMTC + US companies. It’s pretty interesting what you find in the $30-$250m range for optical components, CPUs, memory, and others that are inflecting due to AI. I don’t share these names publicly since risks/volatility is enormous. But one or two going from $40M -> $400m makes the risk/reward worth it for me personally.

Imagine being a Wall Street suit, drooling all over your big fat belly, and refusing to buy $GME in this cycle of obese adults buying card board squares of lizards that can spit fire for 69x the cost to print. Pokemon cards still hold value better than the failing U.S. dollar. Wall Street suits are staring at their silly little models, playing with their dumb discount rate, with the inability to pleasure their wives while GameStop transformed their entire business model.

So update from $LITE + Win Semi ( $SIVE ) foundry: Lumentum in a meeting with Stifel at ECOC 2026 stated: - $NVDA Spectrum-6 CPO UHP demands increased materially. - NPO as larger than CPO, with multi-wavelength external lasers lifting ASPs (Sivers offers multi wave length DFB arrays, read through on higher valued products) - Demand for UHP lasers continues to exceed supply Just a status update in terms of how the optical bottleneck is going (laser prices going up, demand exceeds supply). Digitimes also reported today Win Semi ( $SIVE foundry ) was expanding capacity for CW lasers. - "CW products... are expected to gradually emerge in the second half of 2026", with meaningful revenue contribution likely coming in 2027 and 2028. - Win has strengthened inventory management for InP substrates while moving toward 6-in InP wafers for ongoing process testing. Currently relies on Tier-1 International suppliers. - Many of this was spent on DUV tools from $ASML but (Win Semi's orders spanned machinery, equipment, and fab engineering work) So that answers a lot of questions about Sivers' partner "how is this company securing InP substrates", "4in vs 6in", "production timing" TLDR: - NPO > CPO (per Lite), multi-wavelength lasers going brrr for prices - demand > supply (continuation) - Not sure why people have been bear posting Win Semi when turns out they have everything needed to mass produce CW lasers.
