Lee Chang-dae — CEO

Summary

Lee Chang-dae, CEO of Jangin Investment Club, gives an intraday market update focused on the AI-driven memory semiconductor rally, foreign inflows into Samsung Electronics and SK hynix, and the next opportunities in Korean semiconductor materials and equipment. He also discusses the nuclear power and ESS energy themes, highlights Doosan Enerbility as a key nuclear beneficiary, and points to battery names recovering as the EV chasm is priced in. Later he covers defense/aerospace and construction machinery/reconstruction beneficiaries from Trump-era geopolitical and infrastructure policies, while taking a cautious view on oil prices.

  • Samsung Electronics and SK hynix are seen as early in a foreign-inflow-driven memory upcycle, with HBM and valuation gaps supporting more upside.
  • Micron is viewed as the next AI hardware leader after Nvidia, helping gauge memory strength.
  • Korean semiconductor materials/equipment laggards, especially new-high leaders like Hanmi Semiconductor, Doosan Tesna, and Wonik IPS, may catch up.
  • Nuclear power is a long-term AI energy theme, with Doosan Enerbility as the main Korean representative and US names Oklo and NuScale Power also noted.
  • ESS/battery storage is expected to recover as the EV chasm is priced in; Samsung SDI, LG Energy Solution, and L&F are highlighted for foreign accumulation.
  • Defense/aerospace and construction machinery/reconstruction are possible beneficiaries of geopolitical tension and US infrastructure expansion.
  • Oil has limited short-term upside and long-term downward pressure as Trump policies aim to increase supply.
  • The speaker favors a two-track energy approach in nuclear and ESS while warning that nuclear valuations are high and earnings may take years.
Ideas
Samsung benefits from foreign inflows, HBM.
Foreign and passive fund inflows into Korea typically buy Samsung Electronics and SK hynix first. Samsung has broken through its 110,000-won resistance area, and its move into HBM is seen as starting a new phase where it can become an AI semiconductor beneficiary rather than a laggard. Broker targets of 160,000-200,000 won suggest the rally may still be early even if it pauses.
SK hynix still undervalued in memory upcycle.
SK hynix is a first-choice foreign inflow target and remains undervalued even if its stock doubles or triples, according to the speaker. It continues to hit new highs with memory prices rising, and broker targets around 880,000-900,000 won imply more upside. The current memory upcycle is seen as early rather than late.
Micron is next AI memory leader.
Micron is viewed as the next leadership candidate after Nvidia in AI hardware. Memory prices are rising on data-center demand, and Micron's strong earnings and 10%+ post-earnings move show the market is rewarding memory. Following Micron can help gauge the strength of Samsung and SK hynix.
Nvidia consolidates after big run.
Nvidia is not broken but is taking a breather after a large run; the speaker sees no additional sharp rally for now. This consolidation is allowing Micron and memory names to take leadership.
Korean chip equipment laggards to catch up.
SOBUK names have lagged Samsung Electronics and SK hynix, with many still not properly reflecting the semiconductor upcycle. As Samsung and SK hynix make new highs, SOBUK stocks that break to new highs first—such as Doosan Tesna and Wonik IPS—are likely to lead a stronger follow-up rally, while HPSP and Daeduck Electronics are also notable. The move is not expected to end quickly.
Hanmi Semiconductor leads SOBUK with strong earnings.
Hanmi Semiconductor is highlighted for its strong earnings structure and as one of the SOBUK names that has already broken to new highs. The speaker expects its move will not be short-lived, and it should be one of the leaders as Samsung and SK hynix pull the semiconductor supply chain higher.
Nuclear demand supported by AI and Trump.
Nuclear power is a long-term theme because AI data centers are driving huge electricity demand while energy supply remains constrained. The Trump administration is favoring nuclear over solar and wind, and nuclear construction is a multi-year cycle. Valuations are high and earnings may take years, but the speaker sees too much momentum remaining to treat the theme as a one-year trade. Korean and US names include Korea Electric Power, BHI, GNC Energy, Oklo, and NuScale Power.
Doosan Enerbility benefits from nuclear orders.
Doosan Enerbility is the most representative Korean nuclear company and a key beneficiary of US big-tech nuclear orders and Trump's energy infrastructure push. Foreign buying is concentrated in the stock, and the speaker says the current entry is attractive for both short/swing and long-term investors, though long-term investors should look at a 5+ year nuclear construction cycle.
ESS demand recovers on AI data centers.
ESS is a core energy source for AI data-center expansion and is necessary for solar and wind because those sources are intermittent. Although the Trump administration has weakened the near-term policy push, the speaker expects ESS and secondary battery sentiment to improve from mid-to-late year as the EV chasm is already largely priced in and the market shifts to ESS-driven growth.
Oil faces limited upside, long-term supply.
The Venezuela conflict has not created a lasting oil supply shock, and Trump's drill-baby-drill policy aims to increase global energy supply. The speaker expects limited short-term upside for oil and lower energy prices over the long term.
Samsung SDI earnings inflect on ESS.
Samsung SDI is expected to see earnings capacity fully inflect from this year into the next two years. The EV chasm is already largely reflected in the stock, and the next driver is ESS-related growth. Foreign investors have started accumulating again.
LGES bad news priced, foreigners buying.
LG Energy Solution suffered two large contract cancellations worth about 14 trillion won, but the EV chasm was already known and the bad news may be largely priced in. Foreign investors are buying more aggressively after the price drop, and the speaker sees the next phase as ESS-led recovery.
Foreigners keep buying L&F despite pullback.
L&F's stock pulled back after foreign inflows, but foreign investors are still accumulating shares. This supports the broader battery/ESS recovery thesis.
Geopolitics and SpaceX lift defense aerospace.
Escalating US pressure on Venezuela, Cuba, and Colombia may keep geopolitical tension and defense budgets rising, which could lift defense stocks. Separately, SpaceX IPO expectations could spill over into aerospace names. The speaker presents this as a possible upside catalyst rather than a high-conviction trade.
Reconstruction demand lifts construction machinery stocks.
US geopolitical power projection and infrastructure expansion are expected to raise demand for energy infrastructure and reconstruction, benefiting construction machinery. Caterpillar's long-term strength and recent 4% gain are a signal, and Korean names such as Doosan Bobcat, Jeonjin Construction Robot, HD Hyundai Construction Equipment, Hyundai Infracore, and Caterpillar supplier Jinseong TC are likely beneficiaries. The speaker suggests watching them early.
