KOSPI leads; KOSDAQ turn needs time
KOSPI is near 5,000 and the speaker sees no peak signal yet. Individual deposits above KRW 92tn and ETF inflows are being directed into large-cap index and sector names, so the market keeps favoring large caps even during rotations. He thinks KOSDAQ and small/mid caps may need more time before their turn and wants to keep trading the current large-cap-led trend until signs of a top appear.

U.S. small-cap rotation is finally here
The U.S. market is showing a clear rotation into small and mid caps, with the Russell 2000 up 1.2% and strong this year, unlike prior years when the small-cap call repeatedly failed. He says this year is different and the shift is now visible.
Samsung leads HBM4 over SK hynix
Samsung is gaining leadership over SK hynix in HBM4 because HBM4 uses a logic die made with foundry processes; Samsung has its own foundry, while SK hynix must outsource to TSMC. Nvidia raised HBM4 requirements, and Samsung reportedly scores highest in qualification on speed, heat, and power, with 1c DRAM yield around 70%. Samsung focused on HBM4 rather than the prior HBM3 generation, and its Taylor fab starts this year while TSMC's new U.S. fabs come later, giving Samsung a foundry window plus additional upside from Tesla and double-digit foundry share goals.

TSMC margin risk from U.S. fabs
TSMC's U.S. fab expansion is strategically driven by tariffs and geopolitics, but U.S. production costs are reportedly about 2.6x, which could cut its high operating margin from above 50% to the low 40s. The market is sensitive when high-margin quality names show margin deterioration, so TSMC faces a future earnings and valuation burden even if the expansion itself is necessary.
Biotech selling may be nearing a turn
Korean biotech and pharma have been sold indiscriminately by institutions despite Q1 licensing expectations, but Alteogen's JPMorgan conference comment about an inbound tech-transfer deal has sparked a rebound. If Alteogen holds its move, it could signal a broader sentiment change for the sector next week, especially if licensing news follows.
Alteogen rebound can signal biotech shift
Alteogen's CEO said at the JPMorgan healthcare conference that a new technology-transfer deal for the Hybrozyme platform is inbound, helping the stock rebound sharply. The speaker thinks the UBS report overgeneralized its logic; while the short-term spike may fade, Alteogen can act as a signal shot for a biotech sentiment shift if it sustains the move.
Speculative robot stocks face winner-loser phase
Robot stocks have had a broad, indiscriminate rally in which any name linked to robots jumped or limit-up. He says this phase is entering a caution zone and will shift to separating winners from losers; stocks rising only on robot expectations or possible humanoid entry should be avoided, especially after large gains.
Buy Hyundai robot value-chain revenue names
The center of the robot theme has shifted to Hyundai Motor and Boston Dynamics. Rather than buying any stock loosely tied to robots, he favors companies in Hyundai Motor's value chain or those with direct robot-related sales and revenue from this year, not pure expectations.
SPG is a revenue-backed robot supplier
SPG is a representative Hyundai Motor value-chain and robot component supplier with actual monetization potential. It hit a new high, and he expects such revenue-backed names to show differentiated performance versus pure robot-theme stocks, though valuations are high.
