Summary

Lee Ju-yeon reviews overnight US market weakness and argues Korean equities can rebound at the open. He focuses on AI infrastructure rotation into semiconductors, memory, power, nuclear, optical communication, and substrate stocks, while flagging oil and geopolitical risks. He also discusses conditional pharma/bio recovery and Hanwha Ocean's frigate order.

  • US indexes fell but semiconductor and Korea-related ETFs outperformed, supporting a Korean rebound open.
  • Copper's record-high consolidation supports cable and power infrastructure momentum.
  • AI infrastructure demand is broadening, with nuclear, power grid, optical communication, and CPU/substrate themes active.
  • Memory semiconductor charts and positioning suggest an early upward reversal for Samsung Electronics and SK hynix.
  • CPI/PPI could trigger a rebound in beaten-down pharmaceutical and biotech stocks.
  • Iran-related oil supply headlines push Brent near $100, a key risk level.
  • Hanwha Ocean's Thai frigate order gives cheap shipbuilders a long-term positive catalyst.
Ideas
Lee Ju-hyeon Director, Xangle 2:00
Copper breakout supports cable power stocks.
Copper hit a record high and is consolidating near the highs with a pattern of higher lows; the technical setup suggests an upside breakout can occur anytime, which would give fresh momentum to Korean cable and power infrastructure companies that are the biggest beneficiaries of copper prices.

Nuclear power grid rotation lifts Korean equipment.
US nuclear, SMR, and power grid names surged on AI infrastructure demand; in Korea, Doosan Fuel Cell, Sanil Electric, and LS Electric are direct related beneficiaries, and power infrastructure rotation is continuing even though some subareas have not yet surged.

Tesla uptrend intact after FSD catalyst.
Tesla rose about 4% after FSD approval in Slovenia and continued expectations for the October vote; the stock is rebounding from the lower end of its rising trend channel, and the technical pattern suggests the uptrend and positive expectations remain intact.
Lee Ju-hyeon Director, Xangle 9:53
Pharma/biotech rebound if inflation data tame.
Korean pharmaceutical and biotech stocks have been pressured by high Treasury yields, geopolitical risk, and oil-led inflation concerns; if upcoming CPI and PPI print within expectations, some rate burden could ease and beaten-down pharma/bio could attempt a rebound, but upside is likely capped until then.
Lee Ju-hyeon Director, Xangle 10:39
Memory semis breaking out reversal early.
Micron, SanDisk, and MSCI Korea ETF EWY are all breaking upward from triangle consolidations; Goldman Sachs sees upside for memory semis, hedge funds have very low tech positioning, semiconductor volatility has halved, and in Korea only Samsung Electronics and SK hynix buybacks have been net buyers recently, suggesting an early reversal with elastic upside if institutional flows return.

Hardware momentum beats software now.
The IGV software ETF remains in a downtrend from recent highs while hardware and semiconductor names are turning upward; flows are rotating from software into AI hardware and infrastructure, so the current direction favors hardware over software.

Lee Ju-hyeon Director, Xangle 14:33
Oil watching $100 on Iran risk.
Fox News reported that the US struck Iran's Kharg Island area, which handles the majority of Iranian crude exports; if confirmed, oil supply anxiety persists. Brent is near $99 and WTI near $94, and a break of the $100 psychological level would increase market concern, so the oil setup deserves monitoring.
Lee Ju-hyeon Director, Xangle 18:07
CPU bottleneck supports Korean substrate stocks.
Amazon's AI data center partnership with Qualcomm and a related $4 billion warrant issuance show that CPUs have become a bottleneck in AI infrastructure expansion; Intel, AMD, and Nvidia are entering the CPU market and Qualcomm has secured a large customer. Historically, when the CPU theme is highlighted, Korean substrate stocks move, making them a watch item for related follow-through.
Lee Ju-hyeon Director, Xangle 20:28
Corning deal supports Korean optical names.
Corning's 30-year fiber supply agreement with Verizon and planned US capacity expansion drove optical communication stocks sharply higher; in Korea, RF Materials and Seongwoo Electronics are the representative non-theme names, while most other local optical communication plays are theme-driven and require caution on continuity.
Lee Ju-hyeon Director, Xangle 21:48
Hanwha Ocean order supports cheap shipbuilders.
Hanwha Ocean won Thailand's frigate order worth 680 billion won for the first ship, with potential expansion to 4 trillion won including follow-up orders, giving it new backlog momentum; HD Hyundai Heavy lost the bid, but both shipbuilders are near share-price bottoms and remain cheap long-term opportunities, though near-term upside may be limited by the stronger won and their large market caps.
