Ideas
Battery uptrend intact after speed adjustment
The speaker says the direction for secondary batteries has not changed; the sector is undergoing only a speed adjustment. Battery stocks such as POSCO Holdings, POSCO Future M, and L&F have already surged and may be at the beginning of a new leg, and batteries now trade in the same bullish complex as semiconductors.
Avoid Korean biotech for now
The speaker says biotech should not be bought now and is not even a second-tier sector. High rates are especially damaging to unprofitable biotech, and former tech-export leaders such as Alteogen and LigaChem are in downtrends. Investors who can reduce should reduce; those who cannot sell should simply hold and wait.
AI semiconductor leadership remains intact
The speaker says the AI paradigm is intact and unlikely to break, so the semiconductor leadership complex remains important. Samsung Electronics and SK hynix are cited as past winners that rewarded holders, and semiconductors now move together with batteries as the market’s core bullish sector.
Korean cosmetics ODM exports are booming
Beyond Kolmar Korea, Korean cosmetics ODM companies such as Cosmax and Cosmecca Korea benefit from rapid Korean cosmetics export growth into Europe, North America, and South America. The speaker says quarterly growth is very fast and, within cosmetics, only the ODM names are showing real strength while other cosmetics lag.
Kolmar Korea has expansion and export growth
Kolmar Korea is a Korean cosmetics ODM with capacity expansion and exposure to fast-growing exports to Europe, North America, and South America. It reached historic highs, is now consolidating, and the speaker says it could go bigger later.
Avoid TSE after expiry spike
TSE plunged after expiry-day program trading and a volume spike, and has an investment warning attached. The speaker warns that such expiry-driven spikes are dangerous, and investors should be careful or avoid buying them; better to buy after expiry pullbacks.
AI power demand lifts nuclear infrastructure
The speaker sees AI data-center power demand as a major bottleneck, making power and nuclear infrastructure a key investment theme. Nuclear is increasingly needed, and Korean players can win orders because both APR1400 and AP1000 reactors are order-capable, while U.S. investment and Westinghouse stake talks add catalysts. Beneficiaries include nuclear construction, steel, KEPCO, and equipment suppliers.
Doosan Enerbility wins on nuclear orders
Doosan Enerbility is specifically supported by U.S. investment and gas-power exposure, plus nuclear order potential through APR1400 and AP1000 reactor models and talks about Korea taking a Westinghouse stake. Power bottlenecks should keep demand for its equipment and construction role strong.
Keep 20% cash as dry powder
With FOMC and sector leadership uncertain, the speaker advises not chasing stocks at ambiguous levels and keeping around 20% cash as dry powder. Investors should wait for a new leading sector to emerge and for a confirmed trend before deploying the cash, so they can either buy lower or buy proven strength.
