The KOSPI and KOSDAQ indices are showing a downward trend in early trading on the 6th. This is interpreted to be due to U.S. President Donald Trump stating he would announce tariffs on semiconductor and pharmaceutical items "around next week."

The KOSPI index recorded 3184.26 at 9:03 a.m. on the same day. It fell by 13.74 points (0.43%) compared to the previous day. At the same time, the KOSDAQ index showed a drop of 1.95 points (0.24%) to 796.65.

Among the top stocks by market capitalization in the KOSPI market, Samsung Electronics, SK hynix, and LG Energy Solution are showing a downward trend. KB Financial, Hyundai Motor, and Doosan Enerbility stocks are trading at higher prices than the previous day.

In the KOSDAQ market, Alteogen, Peptron, HLB, and Rainbow Robotics are experiencing weakness. EcoPro BM and Ecopro, which had seen stock price spikes after announcing strong earnings, continue their upward trend even in early trading on this day.

Overnight, the U.S. New York stock market also showed weakness. The Dow Jones Industrial Average fell by 0.14%, the Standard and Poor's 500 index dropped by 0.49%, and the NASDAQ Composite Index recorded a decline of 0.65%.

President Trump not only reiterated his warning about item tariffs, but it also appears that the service sector, which accounts for 70% of the U.S. economy, is showing signs of contraction due to tariffs. The purchasing managers index (PMI) for the service industry in July announced by the Institute for Supply Management (ISM) was at 50.1, falling short of market expectations of 51.5.

As discussions regarding tax reform plans continue to shake the domestic stock market, volatility is expected to remain high for the time being. Han Ji-young, a researcher at Kiwoom Securities, noted, "Until a concrete conclusion is drawn from the tax reform plan, related news may frequently cause noise in the domestic stock market during the trading hours." He added, "In such circumstances, I believe it is more realistic to adopt an approach based on performance forecasts rather than responding to every tariff or tax noise."
