The KOSDAQ index surged over 4%, triggering a 'buy sidecar' for the second consecutive day. This increase is attributed to a wave of bargain hunting in semiconductor and secondary battery stocks, which had seen significant declines recently. The KOSDAQ index fluctuated around the 700 mark during trading.

As of 1:01 PM on November 11, the KOSDAQ index was up 31.75 points (4.16%) from the previous close, reaching 699.36.

Earlier, at 11:28:44 AM, the buy sidecar was activated due to fluctuations in the KOSDAQ 150 futures price and the spot index. Consequently, the effectiveness of program buy orders was suspended for five minutes.

At the time of activation, the KOSDAQ 150 futures price was recorded at 1,158.60, up 66.20 points (6.06%) from the previous close. The KOSDAQ 150 spot index showed an increase of 67.42 points (6.19%), reaching 1,156.27.

The KOSDAQ buy sidecar is triggered when the KOSDAQ 150 futures price rises more than 6% compared to the reference price, and the KOSDAQ 150 index increases more than 3% from the last trading day's final figure, sustained for one minute.

On this day, individual and foreign investors were net sellers, offloading 140 billion won and 38.4 billion won, respectively, while institutions were net buyers, purchasing 173.4 billion won.

Most of the top market capitalization stocks also saw gains. Notable increases included Alteogen (3.74%), EcoPro (8.53%), EcoPro BM (10.67%), JUSUNG Engineering (13.39%), Rainbow Robotics (6.45%), Simtech (9.38%), and IoTechnics (6.25%).

Expectations for government reforms to invigorate the KOSDAQ market also appeared to boost investor sentiment early in the session. The government and the Korea Exchange are pushing to introduce a so-called 'KOSDAQ promotion system,' categorizing listed companies into high-quality 'Select,' general 'Standard,' and management groups.

There were also rumors that the government would hold a meeting regarding KOSDAQ stimulus measures. However, the Financial Supervisory Service stated, "The information circulating online about a meeting on KOSDAQ stimulus measures is entirely false."

The KOSPI index also showed an upward trend. At the same time, the KOSPI was up 122.01 points (2.33%), reaching 5,361.14.

In the securities market, individuals and institutions were net sellers, offloading 536 billion won and 145.3 billion won, respectively, while foreigners were net buyers, purchasing 326.5 billion won.

Semiconductor stocks also performed strongly, with Samsung Electronics (3.44%), SK Hynix (6.02%), SK Square (3.95%), and Samsung Electro-Mechanics (3.29%) all rising.

In the previous day’s U.S. market, the October Consumer Price Index (CPI) exceeded market expectations, and comments from Federal Reserve Governor Christopher Waller raised concerns about the possibility of a significant interest rate hike.

Before the CPI announcement, Waller noted, "If the core CPI rises around 0.3% or more, stronger policy measures may be necessary." Following this, the actual core CPI met Waller's conditions, intensifying concerns about tightening.

Han Ji-young, a researcher at Kiwoom Securities, stated, "The Philadelphia Semiconductor Index narrowed its decline from over -2% to -0.4%, indicating that the impact of the U.S. October CPI shock was limited. I expect the domestic market to show some downward rigidity during trading."
