South Korea’s KOSPI Rises 4.55% Above 5,200 in Early Trading

South Korea’s KOSPI rose above 5,200 points early in the session, gaining 4.55% in a sharp opening move for one of Asia’s major equity markets. The advance puts South Korean shares on the radar for U.S. investors tracking global market moves.

SK Hynix shares climbed 6.7%, and Samsung Electronics rose 5%. Both stocks gained more than the index: SK Hynix’s move was 2.15 percentage points larger than the KOSPI’s, while Samsung’s was 0.45 percentage point larger. The KOSPI crossed 5,200 during the opening stretch, with the index and both named stocks moving higher together.

The KOSPI’s 4.55% gain sat between the two company moves. Among the three reported percentage changes, SK Hynix led at 6.7%, followed by Samsung Electronics at 5%. That places the index’s early rise alongside larger gains in both companies, with the South Korean market’s advance visible at both index and stock levels. All three readings were positive during early trading.
