Summary

Director Lee Ju-yeon reviews the August 15 US market decline and the 10-year Treasury yield surge to 4.7%, arguing the Korean market has likely made a bottom supported by seven weeks of foreign inflows. She expects AI/data-center and physical AI themes, especially semiconductor memory and robotics value-chain names, to remain leadership. She also flags next week's catalysts including Ingenia's IPO, US retail earnings, FOMC minutes, and robot/aerospace events.

  • US equities fell modestly as 10-year Treasury yields spiked toward 4.7% after weak retail sales and consumer sentiment.
  • Rate hike odds have receded, but recession and stagflation concerns are rising.
  • KOSPI and KOSDAQ are seen building a bottom with foreign inflows and potential institutional chase/short-squeeze dynamics.
  • Memory semis strengthened on SanDisk's investor day and Micron re-rating potential.
  • AI data center, power infrastructure, robotics/physical AI value chain, healthcare, and aerospace are key leadership themes.
  • Next week watch Ingenia Therapeutics IPO, Curacle sympathy, US retail earnings, FOMC minutes, robot conferences, and option expiry.
Ideas

Watch 10-year Treasury yield closely.
The 10-year Treasury yield is the most important short-term variable. It surged to 4.7% after weak retail sales and inflation expectations, pressuring growth stocks. Rate hike odds have receded given weak jobs, subdued inflation, and weak consumption, so yield spikes are expected to be temporary, but next week's market direction will likely track the 10-year yield closely.

Memory demand strong; Micron can re-rate.
SanDisk's investor day was well received and confirmed strong memory demand, lifting SanDisk more than 7% and Micron 2.3%. Applying SanDisk's model to Micron implies a re-rating from roughly 6-7x PER toward 10-12x, supporting substantially higher memory-related share prices.
Lee Ju-hyeon Director, Xangle 12:20
Korean market bottomed, foreign inflows returning.
Lee Ju-yeon argues the Korean market has made a meaningful bottom: KOSPI's weekly chart held above prior lows, and this week foreign investors returned with nearly 8 trillion won in net buying on top of seven straight weeks of global inflows. The rally can become self-reinforcing because institutional equity weightings were reduced during the decline and institutions are now underperforming their benchmark, forcing chase buying that could evolve into a short-squeeze-like advance if foreign inflows, semiconductor momentum, and institutional buying continue.

Post-earnings rotation favors earnings-insensitive sectors.
With earnings season essentially over, Lee expects leadership to rotate into sectors where earnings were not the main driver and where the earnings burden had been heavy. Healthcare/biotech, robotics, aerospace, secondary batteries, renewables, and ESS are candidates to strengthen next week.
Lee Ju-hyeon Director, Xangle 22:24
SK Telecom, NAVER, LG data-center plays.
Within Korean AI/data-center names, Lee explicitly says to watch SK Telecom, NAVER, and LG as data-center-related large caps because data center momentum is forming on top of earnings expectations.
Lee Ju-hyeon Director, Xangle 23:34
Physical AI robotics value chain leads.
Physical AI is the main theme and Hyundai Motor is the center of the Korean robot value chain. Lee recommends watching Hyundai Autoever, Hyundai Mobis, HL Mando, SPG, Robotis, LG Innotek, LG Electronics, and also Rainbow Robotics and NAVER as part of the broader physical AI/robotics chain.
Lee Ju-hyeon Director, Xangle 24:48
Curacle moves with Ingenia IPO.
Ingenia Therapeutics, a biotech with more than 1 trillion won in technology-transfer history, lists on Tuesday. Curacle shares the same IPO momentum, so Curacle is likely to move together with Ingenia before and around the listing, with some of that expectation already being reflected.
Lee Ju-hyeon Director, Xangle 25:20
Watch retail earnings for consumer signal.
Next week's US retail earnings from Home Depot, Target, and Walmart will provide a check on consumer health at a time when retail sales and sentiment have deteriorated. Lee says these reports can drive market volatility and should be watched closely.
