Seoul shares opened higher on Tuesday, tracking overnight gains on Wall Street as investors weighed a rebound in U.S. markets amid lingering uncertainty over the Middle East and the artificial intelligence (AI)-backed rally, Yonhap News reported.

The benchmark Korea Composite Stock Price Index (KOSPI) opened 93.93 points, or 1.5 percent, higher at 6,351.38, according to the news agency. The index had plunged by more than 5 percent on Monday after a record 18-percent surge on Friday.

Coverage Comparison

Yonhap News provided two reports on the market opening. The earlier report focused on the opening level, while a later update offered additional details on trading as of 9:15 a.m. and individual stock movements.

According to the updated report, the KOSPI rose 48 points, or 0.77 percent, to 6,305.45 as of 9:15 a.m. The discrepancy between the opening figure and the later level reflects early session fluctuations.

Both reports attributed the positive start to an overnight advance on Wall Street, driven by Amazon.com Inc.'s 4.5 percent gain following strong earnings, which helped lift companies benefiting from demand for AI. The Dow Jones Industrial Average rose 1.32 percent to 53,178.41, while the Nasdaq Composite climbed 2.13 percent to 25,913.90, Yonhap reported.

Falling oil prices also contributed to the broadly positive market sentiment on Monday, according to the reports.

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.
