[Edaily Reporter Kim Kyung-eun] The KOSPI surged by over 8% to reclaim the 8,000-point level, overcoming the fear of “Black Monday.” The KOSDAQ also rose by more than 6%, showing a strong upward trend alongside the KOSPI. This was driven by a resurgence in risk appetite, which led to a massive influx of buying interest, particularly in semiconductor stocks.

According to MP Doctor on the 9th, the KOSPI index closed at 8,096.93, up 612.52 points (8.18%) from the previous trading day.

Individual investors and foreign investors recorded net sales of 615.2 billion won and 2.0027 trillion won, respectively, while institutions recorded net purchases of 2.4982 trillion won. Foreign investors’ net selling continued for the 22nd consecutive trading day.

The index opened at 7,697.76, up 213.35 points (2.85%) from the previous trading day, and immediately jumped to the 7,800 level. After fluctuating throughout the day, it regained the 8,000 level, which had collapsed the previous day.

This is interpreted as a result of the New York stock market rebounding, led by tech stocks, following the suspension of further attacks by Israel and Iran. The stabilization of the won-dollar exchange rate is also seen as having stimulated investor sentiment.

Lee Kyung-min, an analyst at Daishin Securities, explained, “As Middle East risks eased, international oil prices fell and stabilized, leading to increased appetite for risk assets and exerting upward pressure on the stock market.” He added, “As the negative factors that caused the short-term plunge were mitigated and resolved, bargain-hunting flows entered the domestic stock market.”

By sector, electrical and electronics, medical and precision instruments, manufacturing, machinery and equipment, finance, and securities were strong. In contrast, IT services and telecommunications were weak.

In particular, a clear upward trend emerged, centered on large-cap semiconductor stocks that had previously experienced excessive declines. #Samsung Electronics closed at 322,000 won, up 26,500 won (8.97%) from the previous trading day. #SK Hynix closed at 2,215,000 won, up 304,000 won (15.91%) from the previous session.

Among other top-market-cap stocks, #SK Square (13.51%), #Samsung Electro-Mechanics (18.39%), and #LG Energy Solution (2.06%) rose. Conversely, #HD Hyundai Heavy Industries (-1.45%) and others fell.

The KOSDAQ index closed at 967.81, up 56.42 points (6.19%) from the previous session. The index opened at 937.69, up 26.30 points (2.89%) from the previous session, and continued its upward trend.

By investor type, foreign and institutional investors recorded net purchases of 311.3 billion won and 201.4 billion won, respectively. In contrast, retail investors recorded net sales of 512.1 billion won.

#Altogen closed at 326,500 won, up 37,000 won (12.78%) from the previous session, reclaiming the top spot in KOSDAQ market capitalization. #Ecopro BM finished trading at 167,600 won, up 7,900 won (4.95%) from the previous session.

Among other top-market-cap stocks, #Ecopro (2.09%), #Rainbow Robotics (2.13%), #Juseong Engineering (4.87%), #Kolon TissueGene (15.23%), and #Rino Industrial (16.33%) were strong performers. Conversely, #Padu (-3.19%) and others were weak.

Due to the sharp rebound in the stock market, the "side car" mechanism—temporarily suspending program buy orders—was triggered successively in the KOSPI and KOSDAQ markets early in the session.

According to the Korea Exchange, a buy-side sidecar was triggered in the KOSPI market at approximately 9:12:52 a.m. that day. At that time, the KOSPI 200 futures index stood at 1,239.05, up 5.16% from the previous trading day.

The KOSPI buy-side car is triggered when the KOSPI 200 futures price rises by more than 5% compared to the previous day and remains at that level for one minute. When the buy-side car is triggered, the effectiveness of program buy orders is suspended for five minutes.

Subsequently, at approximately 9:28:14 a.m., a buy-side sidecar was triggered in the KOSDAQ market due to fluctuations in the KOSDAQ 150 futures price and the spot index.

At the time of activation, the KOSDAQ 150 futures price stood at 1,676.30, up 104.10 points (6.62%) from the previous day’s closing price. The KOSDAQ 150 spot index rose 90.36 points (5.69%) to 1,676.69.

The KOSDAQ circuit breaker is triggered when the KOSDAQ 150 futures price rises by 6% or more from the reference price and the KOSDAQ 150 index rises by 3% or more from the closing level of the previous trading day, and both conditions persist simultaneously for one minute.
