Seoul Stocks Fall for Second Day as Foreign Selling Persists; Won Edges Up

South Korean stocks ended lower for a second straight session on Wednesday, as foreign investors maintained their heavy selling, according to Yonhap. The benchmark Korea Composite Stock Price Index (KOSPI) fell 62.71 points, or 0.86 percent, to close at 7,208.95. The index had opened 0.72 percent higher but reversed course within about three minutes of trading, later plunging to as low as 7,053.84 during the session.

Trade volume was moderate, with 485.9 million shares worth 39.5 trillion won (US$26.2 billion) changing hands. Losers far outnumbered winners, with 811 stocks declining against 90 advancing.

Foreign Investors Lead Sell-Off

Foreign investors sold a net 2.93 trillion won worth of local shares, marking a 10th consecutive session of net selling, according to Yonhap. The selling was centered on chipmakers and other market heavyweights. In contrast, institutional and retail investors purchased a net 1.1 trillion won and 1.7 trillion won, respectively, helping to cushion the decline.

Market Drivers

The decline was attributed to external factors, including rising U.S. Treasury yields and persistent inflation concerns, which were exacerbated by high oil prices amid extended tensions in the Middle East. Overnight, U.S. stocks extended their decline from recent record highs, weighing on sentiment in Asian markets.

"Foreign investors continued to pull out as rising U.S. Treasury yields and a higher foreign exchange rate weighed on market sentiment, pushing all sectors into negative territory," Lee Kyung-min, an analyst at Daishin Securities, was quoted as saying by Yonhap.

Mixed Performance Among Heavyweights

Most market heavyweights traded mixed. Shares of Samsung Electronics inched up 0.18 percent to close at 276,000 won, after talks with its largest labor union broke down a day ahead of a planned major strike at the world's largest memory chipmaker. Management, however, said it would continue negotiations, stating that a strike should not take place under any circumstances. Its chipmaking rival SK hynix ended unchanged, according to Yonhap.

Currency and Bond Markets

The Korean won strengthened against the U.S. dollar, trading at 1,506.8 won per dollar at 3:30 p.m., up 1 won from the previous session. Meanwhile, bond prices closed lower, with the yield on three-year Treasury bonds adding 0.9 basis point to 3.760 percent, and the yield on benchmark five-year government bonds inching up 0.1 basis point to 3.973 percent, as reported by Yonhap.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
