Hanmi Semiconductor reported Q3 2026 results on 2026-10-26 (before market open); consensus EPS was ₩889.25 — actual not yet in our feed.

Print-day reaction was −3.7% versus the prior close of ₩191,000, with the stock opening and settling below its pre-earnings range on 2026-10-26. The overnight gap to the 2026-10-27 open recovered sharply, adding +4.4%, signalling a meaningful reversal of the initial sell-off after hours. Over the subsequent two trading days (T+1 close through T+3 close), price drifted a further +2.9%, sustaining the post-gap recovery without giving it back. With a null benchmark return preventing a clean CAR calculation, the 3-day total return of +3.1% versus SPY.US sits at the boundary; the PEAD verdict is none with zero conviction — the drift partially offsets the initial reaction rather than confirming a clear directional signal through 2027-01-21.
