VGT dropped 5.17% intraday on Tuesday, as the PCB sector continued to face broad selling pressure and investors locked in profits following a sharp rally in recent weeks.

The stock had previously surged approximately 50% within one week, triggering an abnormal trading volatility alert after cumulative gains exceeded 30% over three consecutive trading days. Northbound capital recorded net selling of HKD 261 million over three sessions, while margin financing also showed net repayment, indicating significant profit-taking pressure. Peer companies FIT HON TENG and KINGBOARD HLDG also declined, extending a multi-day sector-wide correction.

Brokerage research has flagged risks of industry-wide price competition as remote PCB capacity is expected to be released in concentrated fashion, and the interim earnings reporting window has prompted funds to lock in floating gains, suggesting near-term adjustment pressure may persist.
