KOSPI Hits New High Then Plunges; SK Hynix Reaches All-Time High of 2.8 Million Won; Debt-Fueled Investment Supporting Semiconductor Rally Reaches All-Time High of 38 Trillion Won

Summary

The panel discusses a volatile session where KOSPI hit a new high above 9,300 before reversing on geopolitical noise and rebalancing flows. SK hynix surged to a record 2.8 million won, while KOSDAQ slumped. Experts remain firmly bullish on Korean semiconductors—especially SK hynix and Samsung Electronics—citing strong AI-driven fundamentals, the upcoming SK hynix ADR listing, and attractive valuations relative to Micron. Power equipment and Samsung SDI are highlighted as secondary leaders. Conversely, KOSDAQ, biotech, and secondary batteries outside SDI are deemed vulnerable, with investors warned against chasing rotation fantasies.

• KOSPI touched 9,385 before a sharp intraday reversal triggered by Iran deal uncertainties and global index rebalancing.
• SK hynix hit a new all-time high of 2.89 million won, with the ADR listing seen as a major re-rating catalyst.
• Kim Jang-yeol calculates SK hynix and Samsung Electronics fair values at 350K–400K and 450K–500K won, advocating buy-on-dips.
• Vincent passionately argues SK hynix is still a buy even at 280K, expecting massive US active-fund demand.
• Samsung SDI emerges as the strongest secondary battery name, with institutional accumulation suggesting a sector rebound.
• Power equipment stocks (LS Electric, Hyosung Heavy) remain robust, fueled by AI data center infrastructure contracts.
• KOSDAQ and biotech are structurally avoided; Lee Ji-hwan warns that rotation expectations are an illusion and biotech cycles last a decade.
• The biggest near-term risk identified is Micron Technology's earnings next week, with any miss likely to rattle semiconductor shares.
