Intel’s earnings beat expectations by a wide margin, Korean stocks slide

Intel delivered a set of financial results with the fastest revenue growth in 15 years; both profit and guidance came in above expectations, and it even raised 2026 capital expenditures.
AMD released new AI chips on the same day, directly saying performance surpasses Nvidia, targeting a $2 trillion market. The cadence of dense positive catalysts on the supply side suggests that, in theory, stocks should rally across the board—yet Korean stocks fell right at the open.
KOSPI -3%, Samsung -3.5%, SK hynix -4.2%. The index had just broken 7000 points the day before, then gave it all back overnight.
Good news is out, and prices still drop.

Intel and AMD’s positive news is an indirect tailwind for Korean memory stocks, not a direct one. Strong AI infrastructure demand → sustained HBM demand → SK hynix benefits—this chain of logic checks out, but the market isn’t focused on that right now; it’s watching the competitive landscape.
When AMD says its performance surpasses Nvidia, the implication is that pricing power in the AI chip market is loosening. If genuine competition emerges in AI inference chips, Nvidia’s premium could get compressed, and the overall AI infrastructure capex schedule may change—not decrease, but diversify. The money is still the same, but the share flowing to each company starts to shift: the deeper Korean memory manufacturers are tied to whoever is favored, the more uncertainty they have to absorb.

Another pressure point is cash flow.
Intel raised capex, while AMD is rolling out new products—both suggest that procurement decisions by downstream AI giants may become more cautious. Should they wait until the new chips are shipped to place orders, or stock up on HBM at scale now? This wait-and-see sentiment will directly suppress SK hynix’s short-term order visibility, while the market’s valuation for memory stocks has always looked ahead—not at the immediate moment.

On the tokenized stocks side: XSKHY fell 5.59%, SKHYNIX fell 5.94%, and XAMD was almost unchanged at +0.07%. This divergence is telling. AMD put out good news but held up best, while Korean memory stocks dropped the hardest. What the market is saying is that the winner narrative in the chip sector is being reallocated; not every memory manufacturer can benefit in equal proportions in this AI cycle.

My view is that this sector’s volatility in the short term is normal, not abnormal.
Positive catalysts and anxiety are offsetting each other within the same sector—that in itself shows the valuation logic hasn’t converged. Intel’s earnings are a real fundamental signal, but the drop in Korean stocks is also real: the supply side is changing, and the competitive landscape is loosening. Money is waiting for a clearer direction before placing heavier bets again.

At this level, I won’t chase upside on SK hynix-related names, but I also won’t short here. I’ll wait for the real-world performance data of AMD’s new chips, and for the next batch of AI-giant procurement guidance—that’s when the true directional signal will show up.
