Nvidia's AI data center earnings dispel fears.
Nvidia's earnings were strong enough to dispel market worries. Despite memory price increases, Nvidia protected margins around the mid-70% area and showed surging AI data center revenue, with revenue and operating profit roughly doubling year over year. The market read this as confirmation that AI semiconductors are not crashing, and it should give Korean memory and power equipment names a tailwind.
Sanil Electric wins US, domestic power catalysts.
Power equipment and transformer names had been pressured since May on AI data center capex doubts. Nvidia's result plus Trump's executive order restricting foreign power equipment imports, seen as targeting China, gives domestic Korean power equipment a fresh catalyst. Sanil Electric gets an extra edge because US ESS demand is expected to roughly quadruple and Korea's renewable buildout requires specialized transformers; after a sharp pullback, it is a lighter, beaten-down transformer play with both US and domestic demand.
POSCO Holdings rallies on lithium production.
POSCO Holdings is rising because of its lithium business. It completed a lithium plant with about 25,000 tons of production and has begun producing product from its Argentine brine development, so the stock is responding to lithium-related news rather than steel.
Hyundai Steel benefits from electricity tariff cuts.
Hyundai Steel is attracting buyers after a deep decline because local electricity tariff cuts of up to around 7-10% for power-intensive regions lower its electric furnace costs, giving it a meaningful cost advantage. There is also lingering expectation for the US plant being built with POSCO.
Samsung SDI expands US ESS battery capacity.
Samsung SDI is being driven by US ESS demand, which reports say could grow about fourfold. By unwinding/acquiring its GM JV plant and adding Stellantis, it can build roughly 60GW of ESS battery capacity. Analysts are turning positive with target prices near 800,000 won, and Lee thinks it can challenge 600,000-700,000 won from current levels.
Battery materials rebound from cheap base.
Battery materials names EcoPro BM, EcoPro, POSCO Future M and LNF are rebounding from deeply depressed levels. Some fell below last October's base and are now recovering, so Lee sees the materials trading setup as not bad while Samsung SDI leads the sector. He says holders can let it run and use SDI's turn as the sector exit signal.
Hyundai Motor's robot value remains unpriced.
Hyundai Motor's investor day disappointed because it did not talk enough about robots and its buyback was small relative to SK hynix, so the stock pulled back. Lee still sees Atlas robot expectations as alive and argues the market is only paying an auto multiple, with robot value not reflected. The 2028-2033 autonomous driving data collection plan could give it a data advantage versus Tesla, so he advises a long-term accumulation approach.
Samsung Electro-Mechanics and LG Innotek look attractive.
Within the Korean substrate and MLCC complex, demand still exceeds supply and companies keep expanding. For fresh entry, Lee favors Samsung Electro-Mechanics and LG Innotek because their chart setups look the most comfortable, even though valuation work may change the exact ranking.
Isu Petasys needs 120k breakout confirmation.
Isu Petasys has rebounded from around 57,000 won to 110,000 won and has no major valuation burden, with tight substrate demand and a planned 7th factory. However, it is now entering an overhead supply zone, so Lee wants confirmation of a strong break above 120,000 won before new entry; otherwise it could stall.
TLB offers lighter substrate entry than Simmtech.
TLB and Simmtech are receiving Nvidia-linked socket demand expectations, and both are rising off bottoms. Lee prefers TLB as a lighter, easier buy, while Simmtech is fundamentally good but near its high with little pullback, so chasing it leaves less room and requires more thought about resistance.
