Kospi Rises as Chip Buybacks Offset Broad Selling

South Korea's Kospi closed at 6,835.8 points on Tuesday, up 0.23%, as buyback-driven gains in Samsung Electronics and SK Hynix offset net selling from foreign, institutional, and retail investors alike. The index marked its second straight gain, having opened 0.52% lower after fresh U.S.-Iran airstrikes and a hawkish Fed speech from Chair Kevin Warsh unsettled global markets. The Kospi erased losses in the afternoon as government data showed Korea's August exports stayed solid on strong chip demand, with Samsung rising 0.38% and SK Hynix advancing 1.14%, both aided by recently announced buyback programs. Trade volume was light at 263.7 million shares worth 17.5 trillion won ($12.8 billion), with advancers narrowly beating decliners 444 to 421. Foreign investors sold a net 491.9 billion won, institutions sold 634 billion won, and retail investors sold 539.8 billion won. Oil refiners gained on rising crude prices, with SK Innovation up 7.81% and S-Oil up 1.07%, while Hanwha Aerospace fell 3.99% and Celltrion slipped 0.48%. The won weakened 1.8 won to trade at 1,370.4 per dollar as of 3:30 p.m., reflecting broader risk-off pressure from the Middle East escalation.

S-Oil Q2 2026 Operating Income Falls 21.6% Despite Record Lube Margins

S-Oil Corp reported a 21.6% quarter-on-quarter decline in operating income to KRW965 billion for the second quarter of 2026, as a one-off crude-price benefit from the first quarter largely subsided. Revenue rose 26.8% to KRW11.3 trillion, driven by higher crude prices. The lube segment delivered a record operating income of KRW477.4 billion, up 187%, on record product spreads, while the refining segment fell 49% to KRW532.4 billion and the petrochemical segment swung to a KRW44.8 billion loss. Net income stood at KRW514.6 billion, with inventory-related gains shrinking to KRW113.7 billion from KRW643.4 billion in the prior quarter. The company expects strong refining and lube market conditions to persist, supported by supply disruptions and tight supply-demand, and confirmed its Shaheen project remains on track for commercial operation in early 2027.
