Samsung's HBM4 ramp makes SK hynix's ability to defend its HBM lead the key question in the memory race. Chosun Biz reports SK hynix's HBM4 shipments may have missed expectations for a second straight quarter amid Nvidia Rubin delays and chip tuning. Counterpoint puts Samsung's Q2 HBM share at 33%, up from 21%; TrendForce expects strong SK hynix Q3 profits. Samsung is the preferred memory stock right now, though there may be no single clear winner. SK hynix's October 28 report is the next check. x.com
