Ideas
KOSPI rangebound; high unlikely this year.
Lee Jung-yoon says the KOSPI is unlikely to break its previous high within the next three months or this year because negative factors are stacked: foreign selling, AI speed-adjustment concerns, rate-hike worries, geopolitical conflict, and weak retail sentiment. Foreign brokerage targets of 12,000-15,000 are stale maintained calls from much higher levels, not fresh analysis. Still, he sees the market holding relatively well around 6,500-7,000, and a recovery to 7,500-8,000 would be the signal that trend traders are returning; a next-year second-half retest could happen if negatives turn into positives.
Hold 20-25% semiconductors in portfolio.
For a 100 million won portfolio, Lee Jung-yoon says semiconductors should be a core allocation of about 20-25%. Investors with more than 50% semiconductors should reduce, while those with none should build up to roughly 25%. The prior extreme single-stock and ETF-driven concentration is unlikely to return, but semiconductors remain an essential earnings-backed AI sector.
Prefer SK hynix over Samsung for upside.
Within large-cap semiconductors, Lee Jung-yoon prefers SK hynix over Samsung Electronics if the goal is upside from a renewed concentration trade. SK hynix was the prior leadership stock and has much higher beta: it rose about 18x from its low versus Samsung Electronics' 6-7x, so it should move faster on the way up, though it also falls faster. Samsung Electronics is the more defensive choice if the priority is limiting downside, but his answer for preparing for a rally is SK hynix.

Cosmetics exports drive Korean cosmetics sector.
Lee Jung-yoon's second favored sector is Korean cosmetics. He argues cosmetics had the second-best earnings after semiconductors, and Korea has become the world's No. 2 cosmetics exporter after France. That position is unlikely to reverse quickly because cultural image and K-beauty demand are persistent; while export growth may slow, global K-beauty sales through Amazon, the US, and Europe should continue to expand. He suggests one cosmetics-related stock for the portfolio.
Physical AI makes robotics a must-own.
Lee Jung-yoon treats physical AI and robotics as a must-have theme. Robotics already had a huge small-cap move, but he argues large caps must follow because companies that were worth 200-300 billion won rose to 2-3 trillion won, so large-cap robotics names should also be re-rated. Nvidia CEO Jensen Huang's meetings with Hyundai and LG chairmen have changed the market's perception of those groups as robotics-related. He recommends selecting a robotics stock, with large caps worth watching.
Watch AI power equipment beyond semiconductors.
Lee Jung-yoon says the AI investable theme is broader than semiconductors. Power equipment makers with transformer exposure such as HD Hyundai Electric, LS Electric, and Hyosung Heavy Industries rallied for years before semis, with Hyosung Heavy Industries up about 100x over 3-4 years. This shows investors should keep watching AI power infrastructure, not just chips.
LG Electronics is preferred large-cap robotics play.
Among large-cap robotics plays, Lee Jung-yoon specifically highlights LG Electronics. He says the stock's recent chart looks good and its robotics perception improved after Nvidia CEO Jensen Huang met LG's chairman. Although he normally avoids naming stocks, he mentions LG Electronics as a large-cap candidate for the robotics theme.
Watch nuclear and shipbuilding US-investment catalysts.
Lee Jung-yoon says nuclear power and shipbuilding are recent movers and are both linked to US investment themes. If positive US investment news emerges, they have a higher probability of rising. He presents them as candidates for the fourth portfolio slot alongside aerospace and defense, rather than fixed core holdings.
Defense plus aerospace offers long-term growth.
Lee Jung-yoon sees long-term merit in defense plus aerospace. He says the sector has good earnings and growth, and the private spaceflight era is opening, highlighted by SpaceX and Elon Musk's ability to create new markets. Space and aerospace stocks moved on the day of the interview, and he thinks the theme is worth watching into the next week's SpaceX news.
