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 

Sandisk's fast-growing data-center revenue strengthens its case among memory names with upside. Data-center revenue rose 61% quarter over quarter; revenue of $11.03B, adjusted EPS of $49.51 and adjusted gross margin of 85.1% all exceeded estimates. For upside among Micron, Sandisk and Kioxia, Micron ranks first, then Sandisk, then Kioxia, until further guidance. x.com  x.com 

Micron's AI memory-chip sales and accelerating growth support its upside case. Its 3.3/5 WATCH rating reflects a business with 60% of sales from cloud and data-center chips, 64 cents of profit per sales dollar and 256% sales growth last year. At the Oct. 15 close of $878.84, it traded about 42% below estimated fair value of $1,512.34. The case needs strong sales growth and expanding margins and cash flow; slower growth or a price outrunning the business are warning signs. x.com 

Semiconductors could stay undersupplied for a long time as more capable AI per dollar creates more uses and drives compute demand. Micron and NVIDIA trade at low forward P/Es because investors fear peak cyclical earnings, yet current earnings show no slowdown. Shortages may worsen as AI adoption spreads, though the industry could remain cyclical; a reversal of the forced rollover trade is hoped for, not assured. x.com  x.com  x.com 

Micron's cheaper forward valuation, stronger revenue growth and higher five-year ROIC make it the better buy than Sandisk, alongside its exposure to AI-driven HBM demand. Per StockAnalysis, Micron's revenue growth is 256% versus 175%, forward P/E is 5.12 versus 5.84, and five-year ROIC is 27.24% versus 21.47%. Sandisk leads on projected EPS growth, at 23.96% versus Micron's 17.16%. x.com  x.com  x.com 

Each new AI wave is lifting demand across Micron's HBM, DRAM and storage products. Micron said training, inference, agentic AI and physical AI raise memory needs; the stock still trades at about 5x next-twelve-month earnings, leaving its growth story just getting started. x.com 

Micron's surging memory revenue points to a supercycle. Its segment and NAND revenue charts show a sharp recent acceleration, while the stock tests its rising 30-week average. x.com 

SpaceX's beat has relit the AI trade and given semiconductors a fresh catalyst. Chips led Wednesday's close, with AMD, Nvidia, Micron, Marvell and Broadcom all up, but SMH is still below its 21-day average near 594. It needs to hold 536 and reclaim 562 before buyers regain control; 594 is the next test. x.com  x.com 

Strong AI demand and hyperscaler spending make the selloff a mid-cycle correction despite neocloud financing stress. Widening CCC spreads expose leveraged firms to higher borrowing costs; US competition with China supports AI buildout. The base case is a bottom in roughly 5-7 days, then stabilization and eventually a broader reversal, though some projects may fail and valuations compress. IREN, Cipher, Nebius, Applied Digital, Micron, AMD, ASML and Intel are worth gradually accumulating. x.com 

Rising AI equipment demand could sustain the buildout behind Micron, Nebius, Marvell, Bloom Energy and Applied Optoelectronics. ASML says customers are raising short- and medium-term forecasts, some are interested in orders for 2029 or 2030, and its currently planned 2027-28 supply may not fully meet demand. The dip in these AI stocks might be a buying opportunity. x.com
