Amid the announcement of the reciprocal tariff by President Trump on the 3rd, the stocks of major companies by market capitalization in the pre-market (Pre-Market, 8 a.m. to 8:50 a.m.) are not able to escape the downward trend.

As of 8:44 a.m. that day, Samsung Electronics is trading at 57,400 won, down 1,400 won (2.38%) compared to the previous day.
At the same time, SK hynix is trading at 191,400 won, down 6,500 won (3.28%) from the previous day, while LG Energy Solution is trading at 320,500 won, down 8,500 won (2.58%), both showing a downward trend.
Additionally, major companies by market capitalization, including Hyundai Motor, Kia, Celltrion, KB Financial Group, and NAVER, are all showing a downward trend.
On the 2nd (local time), President Trump announced that a 25% reciprocal tariff will be imposed on all products produced in Korea and imported to the United States. This reciprocal tariff effectively nullifies the Korea-U.S. Free Trade Agreement (FTA).
Park Sang-hyun, a researcher at iM Securities, noted, "The content of President Trump’s reciprocal tariff announcement is the worst-case scenario that the market was concerned about," adding, "It is clear that key export products such as automobiles will suffer significant damage to exports to the U.S."
