China Silver-Tech (00515.HK) recently saw a dramatic flash crash characterized by high trading volume, with its share price plummeting by over 80%. This steep decline came after the company's share price had soared more than fourfold in less than a month. China Silver-Tech primarily specializes in the production of printed circuit boards (PCB) and LED lighting products. Since its listing in 2006, the company has witnessed steady growth in its PCB business, while its LED business has secured government project orders across multiple cities in mainland China. As a leading one-stop circuit board manufacturer, China Silver-Tech boasts a global customer base spanning numerous countries and regions. This abrupt share price fluctuation has garnered considerable attention in the market.
