Korean chip stocks will win no matter who survives the AI giants' 'deathmatch': KB Financial Group

KB Financial Group strategist Peter Kim said Samsung and SK Hynix are "not even halfway through" their rally from a valuations and fundamentals perspective, signaling further upside for South Korean semiconductor names. He also noted foreign institutional net-selling of the KOSPI and flagged labor union action as a potential risk for the two companies. The piece is primarily analyst commentary, with limited immediate market impact but supportive of a constructive sector view.

Analysis

The important second-order read-through is that the current rally in Korean memory is still being treated as a cyclical trade by foreign fast money, while local strategists are framing it as an earnings reset with multiple years of runway. That mismatch usually persists until sell-side consensus has fully revised peak-to-trough margins and capex assumptions, which means the biggest upside may still be in the next 2-3 earnings revisions rather than the next headline. If this is right, suppliers with leverage to DRAM/HBM tightness should continue to outperform the broad KOSPI even if index-level flows stay negative.

The labor-union angle is the near-term wildcard because it can hit the market through a different channel than investors are focused on: not just lost output, but a risk premium on execution. Even a short-lived work stoppage can matter if inventories are lean and lead times are stretched, because it converts pricing power into delivery uncertainty and can slow customer qualification for next-gen products. The more interesting implication is that any disruption would likely be used by global buyers to diversify sourcing, which could benefit secondary foundry and memory alternatives over a 6-12 month horizon.

The foreign selling matters less as a signal on fundamentals and more as a setup for squeeze dynamics. When a market is being sold by non-domestic institutions while domestic narratives remain constructive, upside often accelerates on a single catalyst: stronger guidance, a positive AI server order comment, or evidence that margins are extending rather than peaking. The consensus is likely still underestimating how long the memory cycle can stay tight if AI-related HBM demand remains the marginal buyer and foundry utilization normalizes slower than expected.

Key Decisions for Investors

• Long SK Hynix vs short KOSPI Index futures for a 1-3 month tactical pair: expresses the view that memory earnings revisions will outrun passive foreign selling. Use a tight stop if index foreign flows reverse meaningfully.
• Add Samsung Electronics on pullbacks over the next 2-6 weeks, but size for event risk around labor headlines; reward/risk improves if the stock de-rates on union concerns without any fundamental downgrade.
• Buy call spreads on a Korea semiconductor basket for 3-6 months out: upside should be driven by continued estimate revisions, while defined risk protects against a temporary union strike or macro-led de-risking.
• If looking for a hedge, short the KOSPI index against a long semis basket: semis can keep rerating even if the broader market stays weak under foreign net selling.
• Watch for a 10-15% post-headline dip in Samsung/SK Hynix as an entry point; that kind of selloff would likely be flow-driven rather than cycle-driven if earnings momentum is still intact.
