ExtremeVision's stock price plummeted 5.16% during intraday trading on Tuesday, reflecting heightened market concerns about the company's shareholder stability and intensified profit-taking activity.

The decline follows news that Beijing Juyin Ronghe, a wholly-owned subsidiary of ThunderSoft, has reduced its stake in ExtremeVision. According to company disclosures, Beijing Juyin's holding declined from approximately 0.63% of total issued shares prior to listing to about 0.56% after the listing date. This reduction, coupled with discrepancies in earlier prospectus data, has raised questions about the stability of the company's shareholder structure.

Additional downward pressure comes from profit-taking activities after the stock's significant appreciation. ExtremeVision had previously surged over 200% from its IPO price of 40 HKD, reaching a post-IPO high of 128.3 HKD. Market concerns were further amplified by a shareholder depositing shares worth approximately 1.593 billion HKD into CITIC Securities brokerage in Hong Kong, representing about 14.34% of total share capital, which fueled fears of potential selling pressure. The broader Systems Software sector also experienced widespread declines during the trading session.
