AI data and content creation could lift Seagate's and Western Digital's cross-cycle earnings even if supply catches up and pressures prices and margins. Western Digital reported hyperscaler demand signals through 2030/31, making 2013-2024 normalized earnings a poor baseline. Still not a huge fan of their stocks given their large premium to memory makers and Toshiba's production ramp. x.com  x.com 

The valuation gap favors SK hynix and Samsung over Corning, Seagate and Western Digital. Companies trading at 20x are still called cheap while the memory makers trade at 2x; Corning is not cheap on a $4 run rate even with growth, and neither are Seagate or Western Digital. The gap should narrow as memory rises while HDD stalls. x.com  x.com 

Western Digital's margins are riding price increases that management sees lasting three to four more quarters. Price per terabyte rose 28% year on year while cost per terabyte falls less than 10%; December gross margin is guided to 60-61%. At about 10x fiscal 2028 consensus earnings, the stock prices in an early end to hikes despite scarce heads and media that WD mostly makes itself. Buy, $406. Long-term contracts cover less volume further out, leaving spot sales exposed if pricing turns. x.com  … Show more

Seagate's gross margin jump to 57.8% from 52.7% shows pricing power in a supply-constrained hard-drive market. AI data needs storage, hyperscalers seek capacity, and HAMR packs more terabytes into existing factories; roughly 90% of big-cloud data sits on hard drives. Sales reached $4.2B and next-quarter guidance of $4.8B beats the Street's $4.53B. This cycle looks to be accelerating rather than peaking. Overweight, $1,050 target. x.com  x.com 

Western Digital and Seagate have the clearest long setups in storage because they combine higher margins, low competition risk and no concerns about capex or production expansion. That fits a regime where a sharply higher long end rewards free cash flow and punishes capex without an immediate payoff, after a Warsh press conference that raised doubts over Fed inflation control. The risk is that both keep getting dragged down by the broader memory sector, where DRAM and NAND look stretched. x.com 

Western Digital may offer the best chance to get on board, because in a market this concentrated, duopoly economics don't care who gets there first. It just posted the best quarter in its history, though Seagate's HAMR drives are already in hyperscale racks while Western Digital's HAMR ramp starts in 2027. x.com 

Western Digital and Seagate benefit from hard drives being the most constrained part of the AI hardware supply chain. Per TrendForce data cited by @MelvinInvests, hard drives face the longest lead times at 50 weeks, and even with Toshiba expanding production, meaningful relief is unlikely before late 2027 because new capacity takes 12-24 months to build. x.com 

Seagate ranks behind Micron and SanDisk but offers AI cold-storage and enterprise nearline leverage, while Western Digital is solid but offers less pure torque after separating SanDisk. Micron remains king on quality, HBM, NAND and AI leverage, and SanDisk has asymmetric re-rating torque if NAND tightness persists. x.com 

Western Digital benefits from HDDs' low storage cost and growing cloud demand, with higher NAND prices adding pricing power. Nearline bit demand normally grows 20-25% with some deflation, while AI data growth now exceeds 30%; HDD costs ~$0.02-$0.03/GB versus ~$0.25 for NAND. Before AI, the consolidated, ~95% cloud-exposed market looked worth a low-to-mid-teens multiple of normalized EPS. Entry barriers are extremely high, but irrational competition among the three players is a risk. x.com  x.com  … Show more

Seagate and Western Digital look more challenged because hard-disk drives appear to be a less-understood cycle play rather than a real AI thematic. The end state of AI fundamentals looks bearish, with severe multiple compression despite beats, though the path should be a bleed lower with violent rallies back up. Themes tied to agentic activity, such as CPUs, CXL and optics, should still outperform, since tech transitions and share shifts can be monetized whatever the cycle does. x.com  x.com
