Ideas
Favor large caps over crowded small/mid themes.
Samsung's conference call highlighted foundry momentum: it can keep securing 2nm/4nm customers, expand Taylor fab investment, and foundry utilization is rising partly from HBM4 logic die production. Because SK hynix outsources HBM base-die logic to TSMC while Samsung can internalize it in its own foundry, Samsung may gain an efficiency edge. Samsung also gave an aggressive plan to exceed 50% HBM4 in H2, signaling intent to catch SK hynix and creating a competitive risk for SK hynix.
Favor large caps over crowded small/mid themes.
The small/mid-cap leaders in semiconductor equipment/materials, nuclear, and substrate have already rallied too much and look burdensome. Large caps now look cheaper: Samsung Electronics and SK hynix are cheaper than the equipment/materials complex, and Hyundai Motor and Kia have corrected within the robotics theme, so he favors large caps over crowded small/mid themes.
LG Electronics attractive on robotics and earnings.
LG Electronics is an attractive large cap. Q1 earnings were good, with improved vehicle solutions, premium appliance sales, and subscription revenue. Nvidia is repeatedly engaging with LG Electronics on robotics, and LG's hardware strength and home-robot focus, with Cloi at roughly KRW 20-30m, could drive popularization. It is also entering the immersion cooling market. Technical resistance near KRW 150k may slow the move, but he remains interested.
HYBE earnings one-off, leader rebound.
HYBE's earnings shock was mostly caused by one-off bonus payments; excluding those costs, the result can be viewed as a surprise. HYBE is the entertainment leader, rose about 5% despite a weak market, and the sector's valuation premium has been largely resolved, creating room for buying interest as entertainment charts attempt to bottom.
OCI solar-space theme worth watching.
Solar is drawing attention. OCI Holdings joining SpaceX's supply chain could open a new era for solar, and a space-solar theme may follow. He views the theme as worth continued monitoring.
NAVER core strong, rebound expected.
NAVER's earnings slightly missed consensus, but the market is being too harsh. Its core search and shopping businesses are doing well and widening the gap with Google. Although AI results are not yet visible, LLM hallucination is pushing users to cross-check on NAVER, search has risen, and NAVER announced a shopping agent. He expects a rebound from the current level.
AI data center supports cable stocks.
The AI data center theme is not dead. Even with concerns about OpenAI's investment returns, companies are not cutting AI data center investment, so supply should keep flowing to peripheral stocks. Daewon Cable and Taihan Cable have already surged but remain in a strong theme; he advises waiting for pullbacks rather than chasing vertical moves.
Buy optical comm names on dips.
Optical communication stocks corrected after excessive expectations, but a rebound may be attempted. He focuses on names with real ties to Lumentum, Coherent, Marvell, or Samsung: RF Materials is the most important because it actually supplies Lumentum; KMW has a close Samsung 5G partnership and integrated optical components; RFHIC is linked to RF Materials and has Samsung contacts; Oi Solution is also on his watch list. He advises avoiding sharp rallies and accumulating on declines.
Reduce construction exposure after overheat.
Construction stocks rallied on multiple themes - nuclear, decommissioning, low PBR, reconstruction, and housing supply - creating technical burden. GS E&C's earnings shock showed expectations were too high. Hyundai E&C's trend has broken with moving averages in bearish alignment; Daewoo E&C and GS E&C may fall further if they close below the 5-day moving average. He recommends reducing exposure if holding.
Accumulate KOSDAQ ETF on dips.
The KOSDAQ market is not likely to collapse. Government support expectations remain, including the upcoming National Growth Fund with loss protection, and KOSDAQ has lagged KOSPI. As the KOSPI/KOSDAQ gap may narrow and sector drivers such as batteries, biotech, and semiconductor equipment improve, he suggests using a KOSDAQ ETF to accumulate on declines in installments.
