On the KOSDAQ market, a record was set for the largest number of stock prices rising in history. This was due to the U.S. administration of Donald Trump easing mutual tariffs, somewhat alleviating market fears. However, it was reported that still more than half of the stocks have not recovered their prices before the announcement of mutual tariffs by the Trump administration.

According to the Korea Exchange on the 10th, 1,575 stocks rose on the KOSDAQ market that day, while 96 stocks fell and 38 stocks remained unchanged. This surpassed the previous record set on December 10 of last year, when 1,571 stocks rose.

Stocks such as Mirai Semiconductors, ESTaid, ECOBio Holdings, and Hantech hit their upper price limit (the maximum daily price restriction) that day.

The stock price of Alteogen, the leading stock in the KOSDAQ market, jumped 5.61% ($19,500) in one day. The stock price increase rates of ECOPRO BM and Ecopro surpassed 9%. Most of the top market capitalization stocks, including Rainbow Robotics, HUGEL, CLASSYS, and Sam Chun Dang Pharm, showed strong performance.

With the Trump administration deciding to suspend mutual tariffs for 90 days, foreign and institutional investors have entered the KOSDAQ market as 'buyers.' Foreign investors showed a buying advantage of 107.4 billion won that day, the first time in 11 trading days since the 26th of last month. Institutions also made a net purchase of 201 billion won, the largest amount since November 4 of last year.

On the KOSDAQ market, a temporary halt to program buy bids (buy sidecar) was also triggered that day. This was the first time since the sharp rebound after the so-called 'Black Monday' in August of last year.

However, despite the rise that day, there were many stocks that did not recover the losses caused by tariff shocks. Among the 1,619 stocks (excluding SPACs and management stocks) that can be compared with the closing prices from the 1st and that day, 992 (61.3%) showed negative revenue for the month. Stocks such as NE Neungyule, DAEJIN ADVANCED MATERIALS, Mobidays, TXR Robotics, and C&C International experienced significant declines in their prices.
