Summary

Choi Il-ho, Vice President at Chesley Investment Advisory, reviews the sharp selloff in AI infrastructure and semiconductor stocks after Anthropic CEO Dario Amodei's AI pace-adjustment comments. He argues the selloff is sentiment-driven and that underlying AI infrastructure demand and memory fundamentals remain solid, citing Citi's long-term memory outlook and supply shortages. He also covers fund manager survey positioning, energy sector leadership, and key upcoming catalysts such as FOMC and the AI Infrastructure Summit.

  • AI pace-adjustment comments triggered a 5%+ drop in the Philadelphia Semiconductor Index and 5-10% pullbacks in many semiconductor stocks.
  • The speaker views the selloff as sentiment-driven, with fundamentals and AI infrastructure demand still solid.
  • Citi's long-term memory outlook sees continual learning driving HBM, server DRAM, and eSSD demand, with shortages and price increases into 2027-2028.
  • Citi forecasts a 2027 HBM share shift: Samsung rising to 42% and SK hynix falling to 35%.
  • Fund manager survey shows cash at 3.9%, semiconductor longs crowded at 53%, and rotation toward old economy sectors.
  • Energy is the top-performing sector year-to-date at +44.5%, driven by WTI above $100 and the US-Iran war.
  • Upcoming catalysts include FOMC, Q3 earnings preview, and the AI Infrastructure Summit 2026.
  • The speaker advises caution in choppy oversold-stock trading until a clear direction emerges.

AI infra selloff is sentiment, not fundamentals.
The AI pace-adjustment comments from Anthropic triggered a sharp selloff in AI infrastructure semiconductors, but the speaker argues the underlying fundamentals have not been materially damaged and the direction and speed of AI infrastructure demand remain solid. He expects incoming data to confirm that the selloff is sentiment-driven rather than a fundamental break.

AI drives long-term memory demand and shortages.
Citi's long-term memory outlook argues that continual learning will drive memory demand, with HBM, server DRAM, and enterprise SSD demand rising simultaneously and shortages and price increases expected into 2027-2028. The speaker highlights exploding AI token usage and expects memory demand to exceed consensus, supporting the memory semiconductor group.

Samsung gains HBM share; SK hynix cedes.
Citi forecasts a 2027 HBM market share shift: Samsung Electronics rising from about 30% in 2026 to 42% in 2027, while SK hynix falls from 47% to 35%. This points to Samsung gaining high-value HBM share and SK hynix ceding relative share, a key company-level setup within the memory upcycle.
