More memory CapEx may yield proportionally fewer bits as HBM consumes more wafer capacity, supporting SK hynix and Samsung's pricing. Both reported double-digit quarterly DRAM and NAND price gains; Samsung targets 60-70% of mid- to long-term capacity under LTAs. SK hynix has the stronger execution record, but Samsung could benefit enormously from conventional memory without winning HBM4. If trends persist, normalized margins could rise, though memory remains cyclical. x.com 

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. … Show more

SK hynix stands to benefit from higher HBM prices as supply remains constrained. Needham expects HBM price increases next year and tight memory supply through 2030; SK hynix has finalized 2027 HBM prices and volumes with major customers. SK hynix also plans roughly KRW100 trillion in FY2026 shareholder returns, including at least KRW30 trillion in dividends and KRW60 trillion in share acquisitions and cancellations. x.com  x.com 

Memory's thesis keeps getting better as next-generation HBM pricing roughly triples. Per @EhrmantrautCap_, HBM3E sold at $1.50 per Gb, while Samsung is negotiating around $4.50 or more for HBM4 with major customers, before volume even ramps. Memory has been one of the best holds all year, and it is hard not to stay bullish even after the run. x.com 

Samsung Electronics' surging profits show how the AI memory shortage is paying suppliers. Quarterly operating profit reached ₩107tn, nearly nine times a year ago, while sales more than doubled to ₩195.3tn. Alongside SK hynix's results and Microsoft's willingness to pay more for memory, the memory supercycle looks real. x.com 

Higher HBM stack requirements favor Samsung Electronics shares, even as the broader semiconductor industry suffers and DRAM is in dire straits. Daishin Securities says plans for 4-high and 6-high HBM in low-end inference appear shelved, while Nvidia's 8-high Rubin option appears dropped amid base-die supply constraints and customers' preference for bandwidth. x.com 

Micron, Samsung Electronics and SK hynix look very cheap if their long-term agreements do not impose overly conservative price ceilings. Greater clarity on those pricing terms could send memory stocks up 30% in a single day. x.com 

SK hynix's contracted volumes make revenue more dependable than margins. LTAs cover over half of 2027-28 capacity, but not all demand through 2029 is signed, and prices still move within agreed ranges. Big customers' 2027 HBM volume and pricing are settled; HBM4 yields are ahead of plan. Server DDR5 shipments rose over 40% quarter on quarter, though most of the earnings beat came from pricing. Management expects the HBM profit premium over regular DRAM to narrow next year. x.com 

Sold-out HBM and cash returns make SK hynix look too cheap for a memory cycle that has not ended. Its HBM capacity is sold through 2027, 12-layer HBM4 is shipping, and next year's HBM prices are forecast to rise 121%. A completed ₩40T buyback adds shareholder returns; a special dividend funded by a Kioxia stake sale is possible. At roughly 4x earnings by one estimate, the shares could go higher if the AI memory cycle persists. x.com 

SK hynix's strong pricing and secured capacity could push memory stocks higher. Per Wall St Engine, its Q3 DRAM ASP rose by a high-20s percentage quarter over quarter, while long-term agreements cover more than half of its 2027-28 capacity. Those figures support the memory upcycle. x.com
