Summary

Lee Ju-yeon reviews a US session in which the main indexes fell but semiconductors, SK hynix ADR, and optical networking names outperformed. He sees the memory upcycle and AI-driven semiconductor rotation as intact despite oil near $100 and US 10-year yields near 4.85%. He also flags Meta's new AI agent as a competitive threat to Google, is cautious on Apple foldable component suppliers, and warns about close-of-session Korean ETF rebalancing selling in Samsung Electronics and SK Hynix.

  • US indexes fell for a third day, but Philadelphia semis and SK hynix ADR outperformed.
  • Memory pricing expectations strengthened on UBS ASP forecasts and supply shortage views.
  • Oil near $100 and US 10-year yields near 4.85% are macro pressures, but the speaker does not see them breaking the market.
  • Hedge fund underweight positioning supports an 'empty house' rotation into semiconductor and optical names.
  • Meta's free consumer AI agent Muse lifted META and pressured Alphabet.
  • Apple's foldable iPhone launch is seen as limited near-term positive for component suppliers, with memory preferred.
  • About 1.4 trillion won of ETF rebalancing selling in Samsung Electronics and SK hynix may create late-session volatility.
Ideas

Memory supercycle lifts Micron, SK hynix
UBS now sees third-quarter memory average selling prices rising more than 20%, above the prior 15-20% bull case and the 10-15% mainstream forecast, and the speaker highlights supply shortages continuing into next year. Combined with AI agent and inference-driven demand, this supports the memory upcycle and names like Micron, Samsung Electronics, and SK hynix.

AI inference shift lifts AMD, Marvell demand
The shift from training GPU dominance toward AI inference, CPU, and agentic AI demand is broadening the AI trade. AMD and Marvell Technology are beneficiaries of excess CPU demand and data-center revenue surge forecasts, and the speaker frames them as part of the new AI infrastructure leadership rather than just an Nvidia/Broadcom story.

Semiconductor positioning washed out; rotation can lift
Hedge funds have cut semiconductor exposure to the bottom 4% of its one-year range, meaning selling is largely exhausted and positioning is very light. In this 'empty house' setup, even modest reallocation into AI/memory/optical names can keep semiconductor stocks bid despite weak macro conditions.

Optical networking demand continues on AI buildout
AI optical communication and networking names are attracting concentrated inflows as data-center buildout broadens beyond memory. The speaker notes Cloudflare jumped more than 10% and network/platform names also gained, and he sees continued expectations for optical connectivity and platform demand.

Oil and energy stay elevated until midterms
Oil is breaking above the psychological $100 level because the US-Iran conflict is likely to persist until the US midterm elections, with Trump indicating oil may fall only after that. US gasoline inventories are at multi-decade lows, adding upward pressure on crude oil and supporting energy/refining equities as war beneficiaries into that window.

Meta's free AI agent hurts Alphabet
Meta's new Muse AI agent is mostly free, consumer-friendly, and well received by analysts, targeting everyday tasks rather than OpenAI/Anthropic enterprise agents. The speaker sees Meta's installed platform as a major advantage and views Alphabet/Google's high-end assistant positioning as relatively less attractive, which contributed to Alphabet's sharp sell-off.

Apple squeeze makes foldable suppliers unattractive
The foldable iPhone Duo launch is a positive new form factor long term, but near-term Apple is squeezing non-memory component suppliers because memory prices are expensive. The speaker says foldable-related component makers are not attractive for now and prefers playing the memory beneficiaries instead.
