Jeju Semiconductor continued to see strong buying pressure even after a volatility control mechanism (VI) was triggered during the session, recording a surge of more than 18%.

According to the Korea Exchange on the 10th, a static VI for Jeju Semiconductor was triggered at 10:27 a.m. and lifted at 10:29 a.m. The price at which the static VI was triggered stood at 89,700 won.

Even after the VI was lifted, buying pressure did not subside, and Jeju Semiconductor was trading at 91,700 won during the afternoon session. This represents an increase of 14,000 won (18.02%) compared to the previous trading day.

The market analyzes that as investment sentiment toward artificial intelligence (AI) semiconductors, high-bandwidth memory (HBM), and server semiconductors improved, buying pressure spread across the semiconductor sector overall, drawing concentrated investor attention to Jeju Semiconductor.

For reference, the Volatility Interruption (VI) is a system designed to mitigate excessive price fluctuations by applying single-price trading for a certain period when an individual stock's price moves sharply within a short time. Once the VI is lifted, normal continuous trading resumes.

Experts advised that for stocks surging during the session, the likelihood of expanded volatility is high, making it necessary to carefully respond by also checking trading volume, supply and demand changes, and relevant disclosures.
