KOSPI gave up the 6,000-point level it had reclaimed for the first time in 10 trading days just one day later. This is seen as the result of overlapping negative factors, including Samsung Electronics' failure to disclose specific shareholder return plans, LG Chem's sale of its stake in LG Energy Solution, and the collapse of Doosan Enerbility and Daewoo E&C's construction contract for a Czech nuclear power plant.
KOSPI closed at 5,937.66, down 74.78 points (1.24%) on Thursday. The index opened at 6,017.22, up 4.78 points (0.08%) from the previous close, and briefly rose to 6,100.11 during the session before reversing into a decline as a large number of stocks plunged. KOSPI fell as low as 5,817.92 at one point but partially recovered its losses in the afternoon as stocks such as Hanwha Vision rebounded on the back of strong earnings.
