The seller had a deadline — Hynix limit-up, KOSPI +16%, AWS accelerates to 37%

The week's violence had an expiry date, and it passed on Wednesday. Anyone who needed cash by July 31 had to execute by mid-week with settlement lag — which means the flush into Wednesday's lows was calendar-forced, and Thursday was the first session in weeks with the forced seller structurally absent. The tape answered on three continents: the semi fund reclaimed its broken floor in one session, Seoul came back at limit speed this morning, and the after-dark prints delivered the best earnings of the batch. Around the rebound, one new risk got named — by a central bank, in writing.
