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 $1 trillion market cap echoes Cisco in 2000, when the story got too big and multiples went parabolic before the bloodbath. An AI bubble pop is inevitable. x.com 

AI skepticism leaves Nvidia, Broadcom and Micron looking cheap on forward earnings. Their forward P/E ratios are 14, 18 and 5, respectively; the market may eventually stop doubting AI. x.com 

Micron is a loser from the AI-lab drama because it needed AI training runs to stay hot. Elon Musk, Dario Amodei and Sam Altman have pivoted to messaging that AI could kill you, and with AI already polling badly, that could make it very hard for AI to keep attracting the investment dollars it was getting. If the money dries up, a slowdown in frontier training would undercut that demand. x.com 

If Micron has only two years of decent forecasts, its limited visibility warrants a lower multiple, not a higher one. x.com 

Micron's AI-driven cash generation looks outsized for its size amid market concern about debt risk. Its quarterly free cash flow has reached about $32.9B in under two years, above the peak quarters shown for Meta, Amazon, Google and Microsoft; only Nvidia and Apple have posted higher quarters, despite each being about five times Micron's size. x.com 

AI suppliers' profits and signed demand distinguish this buildout from dotcom overcapacity. AI leaders rose 2.9x on 3.1x earnings growth versus 7.4x on 2.1x before 2000; cloud providers have $2.3T in signed backlog. Alphabet, Microsoft, Amazon and Meta could repay debt with about six months' cash flow, unlike 2008's leveraged banks. Micron has multiyear take-or-pay deals and ASML has orders years ahead. Memory profits are cyclical; TSMC, ASML and GE Vernova remain favored in AI's early innings. … Show more

Alphabet's AI capex payback is being repriced, making its post-earnings decline more than a one-day mood swing. Guidance and cloud and AI margin commentary are the near-term tests. If growth continues but the multiple compresses, the risk is duration in mega-cap AI, not a collapse in technology growth. 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 

Apple's roughly 35x forward earnings premium looks unsustainable. If fear around the AI trade fades, its gains could stall or reverse. x.com  x.com
