According to the Korea Exchange on the 18th, at 9:18 a.m., Lunit is trading at 77,600 won, down 6,200 won (7.40%) from the previous trading day.

This is interpreted as being due to the disclosure that Lunit executives disposed of their equity in an off-hours bulk transaction (block deal). On this day, Executive Director Park Hyun-seong, Director Lee Jeong-in, Executive Director Park Seung-kyun, Executive Director Yu Dong-geun, and Executive Director Paeng Gyeong-hyeon sold 64,156 shares of common stock at 77,934 won.

Previously, Lunit saw nearly a 70% increase over the past month as institutions and pension funds made concentrated purchases. The performance of medical AI corporations both domestically and internationally has positively influenced investor sentiment.
