Semiconductor trade faces a capex growth ceiling even if AI delivers what bulls expect. Spending cannot compound at 70-100% a year indefinitely, and compute per dollar roughly doubles every two years, so the same budget buys more capacity later. Today's chip valuations also demand years of 20% AI earnings growth beyond 2028: roughly 10.9 extra years for AMD, 8.9 for ASML, 7 for Marvell and 6.4 for TSMC, versus 1.6 for Broadcom and 0.8 for Nvidia; Micron needs none under the chart's assumptions. … Show more

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 

TSMC may lose pricing power as performance gains shift from shrinking transistors to stacking, interconnects and optics, while logic folding could make older processes competitive. Despite strong leading-edge demand, investors may overestimate the profit share its node leadership can retain. Its cautious expansion and past reluctance toward advanced packaging suggest a risk-averse culture that protects returns but could leave it late to disruptive technologies and key customers. x.com 

Low forward earnings multiples across eleven stocks cannot persist indefinitely. Nvidia trades near 17.5x, its lowest in over a decade; Oracle near 15x, its lowest in six years. Uber is at 17x, Broadcom 19x, Vistra 15x, AppLovin 14.5x, TSMC 19x, Forgent Power Solutions 18x, Nokia 19.5x, American Express 17x and Western Digital 14x. x.com  x.com  x.com  x.com  x.com  x.com  x.com  x.com  x.com  x.com  x.com 

Celestica's conservative guidance and program pipeline leave room for further revenue upside. Its 2027 outlook is $40B, 90% above the $21B 2026 outlook, which has risen four times; a beat looks possible. StockedgeN cites 60-70 new programs, and only a few need to convert to matter at Celestica's scale. Complex racks force it up the value chain. At about 15x next-twelve-month earnings, the stock looks cheap, though a dip may be a better entry. Organic growth takes priority over buybacks. x.com  … Show more

Financing risk makes AI-linked growth stocks unattractive to add here. Much of the money reaching suppliers such as Nvidia and Micron is financed, so harder funding would limit spending on chips, compute and memory. The buildout is not over, but stock prices could remain suppressed until it slows. A significant drawdown would make adding appealing; for many high-beta names with weak fundamentals and balance sheets, the highs look to be in. x.com 

Celestica's Q3 beat and first 2027 guidance make its growth look underpriced. Revenue rose 83% and EPS 109%; management raised 2026 revenue guidance to $21B and put 2027 revenue at $40B-plus and EPS at $21.50, implying about 90% and 85% growth. At roughly 12x 2027 EPS after hours, shares are probably 50% undervalued; initial targets may have upside, with revenue growth potentially reaching 100%. At $34.50 of 2028 EPS and 24x earnings, shares would be worth $828. x.com  x.com  x.com  x.com  x.com 

TSMC's capex plans suggest the AI chip trade is not over for semiconductors, Nvidia, AMD and Micron. CFO Wendell Huang cites robust multi-year demand, including agentic AI, behind $60-64 billion of 2026 capex; TSMC expects 2026-28 spending to be even more significantly higher than in the prior three years. Hyperscaler earnings should reinforce the higher AI capex trajectory. CoreWeave-driven fears feel overdone, though the neocloud model does not appeal long term. x.com  x.com 

AI suppliers' demand may not justify today's investment. Roughly $3 trillion in revenue absent last year is needed to support the spending, yet GDP growth is weak and many companies may be seeing only incremental gains. If the estimate that Anthropic uses two-thirds of its compute for training is right, it could triple inference supply. The most likely outcome for many companies, roughly half the S&P 500, is slowing growth, compressed margins and multiples; when the bubble ends is uncertain. … Show more

TSMC's strong AI demand is straining supply, while solid company fundamentals and attractive semiconductor valuations make an abrupt stop to its advance unlikely. TSMC's Wendell Huang expects 2026-28 capex to be significantly higher than in the previous three years to support customer growth; he says most capex is tied to long-term demand. x.com
