[Financial News] KOSPI gave back some of its early gains in the afternoon, but still managed to finish up 4%.

KOSPI surged sharply at the start of trading, briefly triggering a buy-side circuit breaker for program orders. It climbed as high as 8,434.40 at one point, but the rally lost some momentum in the afternoon.
Institutions and foreign investors bought a net 2.4013 trillion won and 2.1063 trillion won, respectively. Retail investors sold a net 4.3367 trillion won.

Jin-hyuk Kang, a researcher at Shinhan Securities, said, "As the possibility of a ceasefire agreement in the Middle East war came into focus, KOSPI even recovered the 8,400 level intraday." He added, "As the situation in the Middle East quickly shifted from airstrike threats to an imminent agreement, construction stocks also rebounded on hopes for reconstruction."
KOSDAQ closed at 1,029.05, up 32.12 points, or 3.22%, from the previous session. It opened at 1,027.05, up 30.12 points, or 3.02%, from the previous close.
