Korea Composite Stock Price Index (KOSPI) and Korea Securities Dealers Automated Quotations (KOSDAQ) indices turned bearish after just one day. As the expiration date of the tariff mutual suspension set by the U.S. Donald Trump administration approaches, many investors appear to be taking profits.

The KOSPI index showed 3063.22 at 11:16 a.m. on the 4th. It dropped by 53.05 points (1.7%) from the previous day, giving up the 3100 level again in just one day. The KOSDAQ index recorded a decline of 15.45 points (1.95%) to reach 777.88 at the same time.

In the KOSPI market, institutions and foreigners are in a selling advantage, with 1.085 trillion won and 671 billion won, respectively. Only individuals are making a net purchase of 1.692 trillion won. In the KOSDAQ market as well, individuals are engaged in purchasing 2.658 trillion won worth of stocks. Foreigners and institutions are net selling 2.202 trillion won and 480 billion won, respectively.

In the KOSPI market, all of the top 10 market capitalization stocks are trading at lower prices than the previous day. Samsung Electronics, which started off strong, also turned downward, and companies like SK hynix, LG Energy Solution, and KB Financial are showing stock price declines of around 3%.

The KOSDAQ market is similarly affected. The leading stock Alteogen, along with Ecopro BM, HLB, Ecopro, Rainbow Robotics, PharmaResearch, and HUGEL, have all seen their stock prices drop compared to the previous day.

It appears to be influenced by the imminent deadline for the U.S. tariff mutual suspension (July 8). The Trump administration is increasing pressure. Scott Bessent, the U.S. Treasury Secretary, said on a broadcast that if a trade agreement is not reached, the previously set mutual tariff rates will be applied. The mutual tariff rate for Korea announced by the Trump administration in April is 26%.

President Trump also stated on the 4th (local time) that he would send letters specifying the reduced tariff rates to each country. He remarked that the letters would contain information on how much needs to be paid to do business with the U.S., stating, "It will be a tariff of 20%, 25%, or 30%."

The Trump administration has currently concluded trade negotiations with the United Kingdom and Vietnam. It is continuing negotiations with major trading partners, including Korea, Japan, and the European Union (EU).
