SK hynix: Record Q3 profit expectations meet a sharp market sell-off

News on 2026-10-18 pointed to a record Q3 operating profit of about ₩77T, yet shares fell sharply as KOSPI opened down 3.2% on 2026-10-19. The earnings picture in our thesis is unchanged, but the price is now lower and the model's estimate sits well below the earlier-cited price range.

What happened

On 2026-10-18 news reported that SK hynix's Q3 operating profit is expected to reach a record ₩77T, following a similar earnings surprise at Samsung Electronics. This is a media expectation, not a filed result, and we have no filing confirming it.

On 2026-10-19 KOSPI opened down 3.17% at 5,488.41, with SK hynix and Samsung Electronics falling sharply early in trading. SK hynix closed at ₩1,277,000 that day, down 31.2% over one month and 27.6% over three months, though still up 174.3% over one year. Later headlines dated 2026-10-20 mention further declines, with one citing a fall below ₩1.2M, and discuss Solidigm dual-listing concerns; we cannot verify those details from filings. No new filings were attached to these events.
