According to the Korea Exchange (KRX) on the 31st, as of the previous day (the 30th), the market capitalization of the stock market, including foreign stocks, was tallied at 4,347.9260 trillion won.

This is a decrease of 798.4470 trillion won from 5,146.3731 trillion won on the last trading day before the outbreak of war, on the 27th of last month.

During the same period, the KOSDAQ market capitalization fell by 42.5059 trillion won, from 655.2988 trillion won to 612.7928 trillion won. Combining the stock market and KOSDAQ market capitalizations, a total of 840.9529 trillion won evaporated in a month.

With instability in the Middle East continuing until recently, the domestic stock market is also showing extreme volatility. Hundreds of trillions of won in market capitalization are swinging in a single day.

Immediately after the outbreak of war, on the 3rd, the stock market's market capitalization fell by 376.9396 trillion won from the previous day, and on the 4th, when stock prices plunged 12.06%, a record 574.4866 trillion won disappeared, shrinking the market capitalization to as low as 4,194.9468 trillion won.

From the 3rd to the 30th, the combined decline in market capitalization of Samsung Electronics and SK hynix was 371.9574 trillion won. This amounts to 44.2% of the total.

Investor sentiment weakened on concerns that the Middle East war could be prolonged, and Samsung Electronics and SK hynix shares were hit by the TurboQuant shock triggered when Google released "TurboQuant," a technology that can reduce memory usage to one-sixth. In addition, the market capitalization of Hyundai Motor and HD Hyundai Heavy Industries, which face significant concerns about higher materials and supplies prices due to the Middle East war, fell 30.0% and 20.4%, respectively, this month.
