Human-written opinions, AI deep dives, single-ticker research, and factor notes — all the analysis output in one place.
United Epitaxy booked a four-year US datacenter laser deal, Chuan Hsin's InP substrate rallied 22%, Nvidia's Rubin CPX pushed HBM4 models +60%, and Japan's HBM probe suppliers doubled operating profit — one chain, four countries, one physical constraint
SK Hynix's supplier neighborhood is still white-hot, but a CXMT threshold breach and a QoQ NVIDIA inventory build are pricing Korea's memory premium for a compression the export headline is hiding.
Korea's July HS8542 semiconductor exports surged +166.29% YoY to $32.7B, the eighth consecutive triple-digit month, and on the surface that print reads as vindication for SK Hynix (000660) and Samsung Electronics (005930). Underneath the headline, three data points complicate that read. CXMT's DRAM market share broke 10% for the first time, the Chinese memory maker began HBM3E production, and NVIDIA (NVDA)'s DSI extended to 119.7 days in 2027-Q2 from 115.1 days a quarter earlier — a ~5-day inventory build against the exact node Korean memory is priced against.
Three days that closed out NVIDIA's identity as a merchant chip vendor — software, CPU, GPU, and rack all sold from the same counter.
The final chapter of the three-vendor oligopoly — Korea, US, Taiwan, and Japan reorganize around a fourth line, all at once
The memory shortage stopped being a data-center accounting problem and reached the store shelf
Google TPU orders ease, Anthropic surges — a structural shift where one AI lab now anchors both custom silicon and merchant GPU roadmaps
