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 

Sandisk's datacenter shipments and restrained bit-supply plan strengthen its growth case, without settling contract protection in a downturn. Management attributed roughly 60% of fiscal Q1 revenue growth to volume and 40% to price; datacenter sales rose 61% sequentially to $4.8B, supplying 88% of total growth. It retains mid-to-high-teens bit growth rather than accelerating supply. Consumer sales fell 29%, and the CFO cautioned against carrying Q2's growth rate into fiscal Q3. x.com  x.com 

SanDisk's data-center flash growth shows AI inference is becoming a larger storage customer. Data-center revenue reached $4.8bn, up 61% in a quarter and over 40% of sales; total revenue of $11bn and EPS of $49.51 beat expectations. Guidance of $12.4bn revenue and $56 EPS suggests feared supply normalization has not yet eroded pricing. Overweight, with a $2,700 target. x.com  x.com 

Networking, power and compute look more durable than cyclical memory in the AI buildout. Lumentum's revenue compounded year after year across the 2010s and 2020s, unlike Micron's; AWS revenue also compounded. Lumentum, Nebius, Bloom Energy and Credo should heavily outperform SanDisk and Micron from here, though AI itself remains heavily doubted. x.com  x.com 

A supply response could compress Western Digital's pricing and margins, eroding its apparent cheapness. Its 2013-24 normalized earnings merit a look: even huge demand growth in other industries eventually drew supply and mediocre returns. A digestion/reset would hurt buy-and-hold investors, though the outcome is uncertain. Pre-AI economics were mediocre and unlikely to become amazing post-AI; TSMC's stronger pre-AI economics make its post-AI case better. x.com  x.com  x.com 

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 

AI data-center investment needs outside AI spending to rise 33-fold by 2030 to break even. Hyperscalers hold $4.5 trillion in debt and future liabilities, but corporate and SaaS token spending outside circular deals is only $60 billion annualized against a $2 trillion break-even ARR. SK hynix says memory shortages may last until 2031, raising capex and CoreWeave default risk; Mitsubishi warns turbines are booked through 2031 and cost 400% more, delaying CoreWeave and Oracle data centers. x.com  … Show more

Deployment limits will slow AI hardware spending and expose cyclical suppliers such as SK hynix. Amazon has hardware waiting for power, and Broadcom's CEO said some clients delayed shipments because they could not deploy. Cheap forward multiples can mark a cyclical peak as analysts extrapolate growth. The slowdown could have begun or be a year away; timing is uncertain, so reducing cyclical risk in favor of healthier, genuinely cheap names looks better. x.com  x.com  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

Sandisk's growth is coming entirely from higher prices, not more bits shipped, which makes it hard to sustain. Revenue grew 97% quarter over quarter as almost every hyperscaler raised capex to cover rising prices. Its roughly 80% gross margin is excessive and customers resent it; as long as demand far exceeds supply it can keep both, but supply eventually catches up and margins will erode. The open questions are how long new fabs take and whether Sandisk or rivals add the supply. x.com  x.com  … Show more
