Summary

The panel reviewed the August 18 KOSPI and KOSDAQ reversal, where an AI-led morning rally collapsed after Japanese yield and yen-carry-trade fears triggered foreign selling. Kim Jang-yeol argued that the AI and memory demand story remains intact and that Korean memory is cheap versus US peers. Lee Kwon-hee highlighted individual longs in PCB and equipment names, LS Group, refining, food, KOSDAQ tech, and shipping, while advising tactical caution on index levels.

  • KOSPI fell 1.5 percent to 6,869 and KOSDAQ fell 3.52 percent to 834 after a strong morning and weak afternoon.
  • The panel attributed the reversal mainly to Japanese JGB yields, poor bond auctions, and yen carry trade liquidation fears.
  • Kim Jang-yeol said AI investment is underpinned by real capital and token growth, so the memory uptrend should resume.
  • SK Hynix and Samsung Electronics are viewed as lagging US memory names and cheap enough to catch up.
  • Lee Kwon-hee discussed bullish setups in Isu Petasys, LS Corp, LS Electric, S-Oil, Samyang Foods, Silicon2, Hana Micron, HPSP, and HMM.
  • Index technical levels were defined: KOSPI must hold its 120-day moving average, while KOSDAQ is above its 50-day moving average with possible 900 upside or 800 downside.
  • The panel viewed yen carry trade unwind as a present risk but likely less acute than in 2024.
Ideas
Kim Jang-yeol Reporter, The Bell 17:15
Korean memory names will catch up.
US memory names have surged because AI investment is backed by real capital and long-term memory contracts, while Korean memory names lagged due to macro and yen-carry fears. Korean memory remains cheap versus US comps, with SK Hynix at about 3.8x P/B versus its US ADR at 5.6x, and the memory cycle is not over, so SK Hynix and Samsung Electronics should catch up.
Lee Kwon-hee CEO, Economist 37:00
Isu Petasys expansion makes it buyable.
Isu Petasys is entering a Samyang Foods-like phase where additional capacity creates direct revenue upside. Its sixth factory expansion and high-end accelerator PCB demand for AI data centers support estimates, and valuation has de-rated to about 18x next-year guidance, making the stock buyable after being overvalued in April.
Lee Kwon-hee CEO, Economist 39:02
LS Corp breakout could accelerate gains.
LS Corp has repeatedly tested its 120-day moving average and could break out sharply. Subsidiaries including LS Cable and unlisted LS-related businesses are earning well, and valuation has fallen to about 1.4x PBR and about 13x next-year PER, suggesting limited downside from here.
Lee Kwon-hee CEO, Economist 40:37
LS Electric contract supports upside.
LS Electric signed a 48.6 billion won Blue Energy contract, reviving positive sentiment after a weak recent flow. The stock rose intraday and closed higher despite the weak market, showing company-specific demand.
Lee Kwon-hee CEO, Economist 41:03
S-Oil benefits from refining margins.
Refining margins are very strong because gasoline, diesel and jet fuel supply is tight. S-Oil has already risen about 60 percent from its bottom, and Korean refiners benefit from relatively cheap Dubai crude and improved blending technology, supporting continued upside.
Lee Kwon-hee CEO, Economist 43:05
Samyang Foods overseas demand strong.
Samyang Foods found strong support near the 1 million won area and is up about 30 percent from its bottom. Second-quarter overseas sales exceeded 600 billion won for the first time, with strong foreign demand for Buldak ramen and related snack products, so earnings remain solid.
Lee Kwon-hee CEO, Economist 43:36
Silicon2 funding could fuel breakout.
Silicon2 received third-party allocation investment from CVC Capital to accelerate global expansion. The stock had already moved before the news, and if the market stabilizes and reflects the event, it could break above 50,000 won.
Lee Kwon-hee CEO, Economist 44:31
Hana Micron earnings are good.
Hana Micron reported solid earnings on August 15. The stock rose more than 7 percent and then gave back gains because of the weak market, not because of company-specific news, so the fundamental story remains positive.
Lee Kwon-hee CEO, Economist 45:36
HPSP order expectations are building.
A new report highlights additional order potential for HPSP, including expected North America expansion and mandatory use of Land 300+ technology. The stock is recovering toward prior levels after a patent-dispute-driven pullback.
Kim Jang-yeol Reporter, The Bell 47:04
HMM gains on Red Sea rerouting.
HMM surged as geopolitical risk and Red Sea disruptions create expectations of longer shipping routes, which should support freight rates. The Red Sea issue could be a bigger driver than Iran tensions, keeping shipping rates elevated.
Lee Kwon-hee CEO, Economist 69:23
KOSPI KOSDAQ levels need watching.
KOSPI closed just above its 120-day moving average near 6,869; if it loses that level, 6,500 is likely. KOSDAQ is holding its 50-day moving average and could challenge 900 if it holds, but another spike in US yields could push it toward the low 800s.
