Summary

CEO Lee Juhyeon analyzes the market divergence where KOSPI fell sharply on Samsung and SK Hynix profit-taking while KOSDAQ surged, led by robotics and healthcare stocks. He attributes positive momentum to easing oil prices and reduced rate-hike fears. Confirmation of massive AI capex from US big tech earnings strengthens the semiconductor demand thesis, and he sees Samsung Electronics as a buyable dip.

  • KOSDAQ jumps 4% on robotics and healthcare strength, while KOSPI drops 4% as Samsung and SK Hynix correct after Friday's historic surge.
  • Oil falls to $80 on US-Iran de-escalation, easing inflation and rate-hike concerns, benefiting growth stocks.
  • Amazon, Google, and Microsoft earnings confirm sustained AI capex, destroying fears of spending cuts and supporting Korean semiconductor names.
  • Samsung Electronics is viewed as a dip-buying opportunity with stronger technicals; SK Hynix faces near-term resistance.
  • Robot stocks showed early relative strength, breaking above 20-day MAs before the index, signaling a sector leadership role.
  • Healthcare/biotech stocks rally with institutional fund buying concentrated in names like SPG, PharmaResearch, and Petron.
  • Foreigners take profit after heavy two-day buying; KRW strengthens to 1,430, positive for equity sentiment.
  • Geopolitical uncertainty and a still-intact downtrend warrant caution despite emerging positive signals.
Ideas

Healthcare sector rally on growth rotation.
Healthcare and biotech stocks are contributing heavily to the KOSDAQ rally as representatives of the growth sector. Institutional fund buying is flowing into select names, and the sector is moving strongly, supported by easing oil prices and rate fears.

AI capex cycle intact, semiconductors benefit.
Big tech (Amazon, Google, Microsoft) earnings confirmed massive ongoing AI capex, shattering fears that profitability concerns would cause capex cuts. Amazon's AWS has a nearly 700 trillion won order backlog from AI companies, ensuring long-term demand. This is structurally positive for Korean semiconductor companies as the 'shovels and jeans' suppliers to the AI buildout.

Robotics sector leads with early reversal.
Korean robotics stocks have already been forming bottoms and breaking above their 20-day moving averages while the broader KOSDAQ index remained below. This early relative strength and trend reversal signal that the robotics sector is leading the market recovery and could continue to show strong upside.

PharmaResearch backed by institutional buying.
PharmaResearch is seeing strong institutional fund buying in a weak market. It is one of the stocks that received the heaviest net purchases from institutional funds recently, and its price is responding well, indicating a positive supply/demand setup.
Lee Ju-hyeon Director, Xangle 16:30
SPG benefits from institutional accumulation.
SPG, a robot reducer supplier, is one of the stocks where institutional funds have been net buying most aggressively even during the market's sharp decline. This institutional accumulation and the resultant strong price action make it worth monitoring for follow-through.
Lee Ju-hyeon Director, Xangle 17:03
Petron power on pre-rally base build.
Petron had already formed a base camp and established a base at support, turning its trend higher before the broader KOSDAQ rally began. This technical preparation allowed it to hit the daily price limit when the market sentiment improved, showing strong momentum.
