Other corporations became a major source of demand in South Korea’s stock market, recording more than ₩1 trillion in net KOSPI purchases for seven consecutive sessions from the 20th through the 28th. Their cumulative buying reached ₩10.19 trillion, including ₩1.06 trillion in the final 10 minutes of trading on the 28th, as Samsung Electronics and SK Hynix carried out large treasury-share buybacks. Despite the buying, the KOSPI remained trapped between 6,700 and 6,900 and failed to build momentum toward 7,000. The two companies have planned buybacks totaling ₩55 trillion, leaving an estimated additional buying capacity of more than ₩46 trillion. Samsung Securities senior analyst Kwon Beom-seok said the buying trend could continue for roughly 30 more trading days, or at least a month and a half, if the companies maintain their current pace. Rising U.S. long-term Treasury yields, high oil prices, capital rotation ahead of Anthropic’s large-scale IPO and uncertainty over Federal Reserve policy remain constraints on the market.
