Korea's Sidecar Day: KOSPI 7,284, Hynix +8.9%, Samsung +6.3%

Korea's markets surged on Wednesday as ASML's earnings beat and softer US inflation ignited a semiconductor rally that triggered buy-side sidecars on both KOSPI and KOSDAQ.
KOSPI closed at 7,284.41 as SK Hynix jumped 8.93% to 2,082,000 won (roughly $1,397) and Samsung Electronics gained 6.27% to 279,500 won (approximately $188 per share), with foreign institutional flows driving the broad advance. Off the trading floor, Korea Securities Finance announced its first foreign currency bond targeting $300–500 million, while Meritz Financial Group entered talks to inject 200 billion won (approximately $134 million) into Homeplus under a court-led rehabilitation plan. The Bank of Korea rate decision is the key watch item for Thursday.
