On October 21, the KOSPI index rose by 2.73%, fluctuating around the 5700 mark.
According to the Korea Exchange, as of 1:43 PM, the KOSPI index recorded an increase of 152.76 points (2.75%) to reach 5704.02 compared to the previous trading day.
The KOSPI opened at 5666.34, up 113.60 points (2.05%), and gradually expanded its gains, reaching a peak of 5816.43 during the session.
In the securities market, retail investors sold a net 1.19 trillion won, while foreign and institutional investors bought a net 463.5 billion won and 20.2 billion won, respectively.
The strong rise is attributed to a rebound following the KOSPI's sharp decline of 3.73% the previous day and some gains in the New York stock market overnight, which led to a wave of buyback in the domestic market.
Notably, the positive sentiment was bolstered by the strong third-quarter results from U.S. AI server company Supermicro, as well as optimistic remarks from Elon Musk regarding AI revenue during SpaceX's earnings announcement.
Due to the strong buying momentum, a sidecar was activated in the morning. The Korea Exchange suspended the effectiveness of program buy orders for five minutes at 10:51:56 AM due to fluctuations in the KOSPI 200 futures index.
The sidecar is triggered when the KOSPI 200 futures price rises more than 5% compared to the reference price and remains at that level for one minute. At the time of activation, the KOSPI 200 futures index was up 44.94 points (5.22%) at 904.84 compared to the previous day's closing price.
As of this time, Samsung Electronics was trading at 222,000 won, up 4.96% from the previous day, while SK Hynix was up 4.17% at 1,274,000 won. Most of the large-cap stocks, including SK Innovation (3.78%), Samsung Electro-Mechanics (0.43%), and SK Square (2.97%), were also rising.
