Kospi Opening Figures for Nov. 10 Could Not Be Verified Amid Diverging Prior Session
Key Facts
The figures circulating for the Kospi’s opening on Nov. 10, 2026, including the percentage gain and index level at the start of the session, could not be verified. The account of a surge attributed to that opening therefore cannot be confirmed or treated as a verified move in the South Korean market that day. EL7 data show the index closed at 5,018.85 points on Nov. 9, a figure for the previous session that does not establish the following day’s opening performance. The Associated Press also reported that the Kospi fell 0.8% in the Nov. 9 session. Accordingly, the Nov. 10 opening figures remain unconfirmed in the information available.
The Kospi’s decline on Nov. 9 contrasted with the performance of other markets in the region, according to an Associated Press report, which said regional markets rose in the same session. In the United States, the S&P 500 rose 2.3% and the Nasdaq 2.7% that day. Brent crude also fell 5.8% to $92.57 a barrel. These figures provide context for markets on Nov. 9, but do not establish that U.S. stocks or the decline in oil caused the Kospi’s move at the opening of the Nov. 10 session. The information available contains no independent confirmation of the Korean index’s performance at that opening.
Semiconductor stocks remain important to the context of the Korean market. Reuters reported that Samsung Electronics and SK Hynix are among the market’s largest components and prominent beneficiaries of demand linked to artificial intelligence. But that background does not establish the sector’s performance or contribution to the Kospi’s move during the Nov. 10 session. On Oct. 29, Samsung reported record quarterly operating profit of 107.4 trillion won for the third quarter of 2026, attributing it to strong demand for memory chips used in AI systems. The results offer a glimpse of the importance of the company’s memory business, but are not evidence of how its shares moved in the session in question.
The Associated Press said Samsung and SK Hynix together controlled about two-thirds of the global memory market as of Oct. 29, 2026, amid strong demand for their chips driven by the AI boom. On Oct. 28, SK Hynix reported record operating profit of 83.3 trillion won in the third quarter, compared with 11.4 trillion won in the same period a year earlier, Reuters reported. The news agency said demand for AI infrastructure had lifted memory prices. The results place major Korean companies at the center of the memory-chip demand story, but do not by themselves reveal how their shares or the index performed at the Nov. 10 opening.
