What happened that day?

The KOSPI rose 9.63% to close at 5,583.90 — snapping a three-session slide
The day before had been the index's worst single day since it began. The direction reversed completely in 24 hours
The trigger was a report that Iran had approached the United States about talks to end the war
The strikes were still going on. What the market bought was not the situation but the signal that it could end
A pause in the oil spike helped too — almost everything moving the KOSPI in this stretch ran through the oil price
The rebound did not end the episode. The index fell further into late March and only recovered in April
