Samsung Electronics closed at 272,500 won, up 0.93%, on the ex-dividend date for a third-quarter special payout estimated at nearly 30 trillion won ($21 billion). The gain followed a 5.43% drop the previous day and ended six consecutive quarters of declines on ex-dividend dates. Analysts linked the rebound to valuation appeal after the sharper-than-dividend-yield selloff and expectations for further shareholder returns. The stock held up despite the 10-year U.S. Treasury yield exceeding 5.2%, Middle East conflict concerns and reports that OpenAI had paused work on its next-generation artificial intelligence model over safety concerns. SK hynix fell 0.17% to 1.765 million won amid concerns about a dual listing of Solidigm. Samsung's third-quarter dividend is estimated at 4,568 won per share, including 370 won in regular dividends and 4,198 won in special dividends, implying a yield of about 1.7%. Securities analysts expect a further shareholder-return announcement in late October, potentially larger than the current quarter's special dividend. Samsung said it will disclose the specific dividend amount after its late-October earnings release.
