KOSPI closed at 6,813.34 on 2026-08-13, soared 3.6% on the session and is +61.7% year-to-date. Here is what the market data shows.

South Korea's KOSPI ended the 13 August session at 6,813.34, up 3.56% on the day, the largest single-day move anywhere in the fifteen-market peer table used for this wrap. That gain extended an already sharp week, over which the index added 8.21%.

Zoom out, though, and the picture stops being straightforward. Year to date the KOSPI is ahead 61.68%, and it now sits 117.67% above its 52-week low of 3,130.09. Yet the same index closed 25.25% below its 52-week high of 9,114.55, and finished under its 50-day average of 7,441.48, the line that tracks roughly the last two and a half months of trading. Over three months it is down 13.14%, and over one month down 0.63%. It does remain above the slower 200-day average of 5,857.76. A market can be having an outstanding year and a poor quarter at once, and this one is.

Peer closes in the pack do not all carry the same date, so they cannot be read as one shared session. Among those stamped 13 August, the Nikkei rose 1.16% and Taiwan's TAIEX 1.11%, while Hong Kong's Hang Seng eased 0.17% and the Shanghai Composite 0.5%. In Europe the DAX added 0.54% and the CAC 40 0.2%, with the FTSE 100 off 0.19%. The most recent US closes recorded here are dated a day earlier, 12 August: the S&P 500 up 0.26%, the Nasdaq up 0.54%, the Dow down 0.04%.

Coverage circling the move leaned on two themes. According to a report from Bloomberg, Korean equities climbed 22% over ten days as strength in chipmakers resumed. CNBC and Business Insider each ran pieces describing the market as having re-entered bull-market territory following its recent slide, and a TradingKey piece put the bounce at 30% while asking in its own headline whether that description really holds. The Business Times reported that softening expectations of rate increases lifted Asian equities, giving the Korean move as 3.7%, a reading taken at a different moment of the day from the 3.56% close recorded here.

None of that is established by the data itself. This pack holds prices, ranges and peer closes, not sector breakdowns, fund flows or policy releases, so it cannot confirm that semiconductors or rate expectations produced the session's gain, only that published reports say as much. What the numbers do settle is the tension: a very large year, a very large day, and an index still a quarter below where it traded at some point in the past twelve months. Investor's Business Daily, 17 days ago, was writing about the same market entering a bear market, which is a fair measure of how quickly the framing has moved.
