KOSDAQ Surges Over 5%, Triggering Buy Sidecar; KOSPI Also Rises

South Korea's KOSDAQ stock market experienced a significant rally on August 10th, with the index soaring over 5% and prompting the activation of a "buy sidecar" for the third time this month. The surge was led by the bio sector, with companies like Alteogen (+15.82%) showing substantial gains. This was followed by strong performances in other key KOSDAQ sectors, including secondary batteries, robotics, and semiconductor materials, indicating a broad-based market upturn.

The KOSDAQ 150 futures price and the KOSDAQ 150 index saw rapid increases, leading to the temporary suspension of buy orders for five minutes starting at 9:50 AM. This marks the 18th instance of a buy sidecar being activated this year, highlighting the market's volatility and rapid upward movements.

Beyond the leading bio stocks, other prominent companies also contributed to the rally. EcoPro, a major player in the secondary battery sector, rose by 6.05%. Rainbow Robotics, a leading robotics firm, gained 4.19%. In the semiconductor materials, components, and equipment sector, Jusung Engineering saw a significant increase of 10.25%. Overall, 1,338 stocks on the KOSDAQ rose, while only 303 declined, reflecting widespread investor confidence.

Meanwhile, the broader KOSPI index also participated in the positive trend, rising by approximately 1% during morning trading. Major KOSPI components like Samsung Electronics saw a 0.54% increase, and SK Hynix gained 1.48%, indicating a generally optimistic sentiment across the South Korean stock market.
