Summary

Park Se-ik and Choi Ho review a BNK Investment Securities downgrade of Samsung Electronics and a cautious outlook on SK hynix, both tied to slowing memory demand and rising supply. They also cover sector rotation in the Korean market, the debate between Jensen Huang and Dario Amodei on AI development speed, and the US 10-year Treasury yield breaking above 5%. Park Se-ik concludes that the 10-year yield may peak in October and turn lower, drawing a parallel to 2018.

  • BNK Investment Securities cut Samsung Electronics' target price and rating, citing limited upside after foundry recovery expectations.
  • BNK maintained a Hold on SK hynix, seeing solid AI server demand but slowing momentum and worsening memory supply-demand.
  • Korean market leadership shifted toward secondary batteries, power equipment, financials, and defense, while securities and auto parts lagged.
  • The AI safety debate contrasted Jensen Huang's push to accelerate adoption with Dario Amodei's call to pace frontier model development.
  • US 10-year Treasury yield broke above 5%, raising concerns about prolonged range-bound markets and high-rate pressure.
  • Park Se-ik expects the 10-year yield to peak in October and fall, citing seasonal patterns and the 2018 yield-break analogy.

US 10-year yield to peak and fall.
The US 10-year Treasury yield has broken through the psychological 5% level, and while the chart still suggests further upside until a clear top forms, the speaker's quantitative seasonal work shows October has often marked the high. He therefore thinks the 10-year yield may peak in October and then turn down. He compares this to 2018, when a break above 3% in the 10-year yield coincided with a sharp equity selloff, followed by a rapid decline in yields to 1.5% in 2019 and a subsequent rally, suggesting a similar peak-and-reversal pattern could be developing.
