Rising Technology: Stock price abnormally fluctuates, indicating multiple investment risks.

Zai Sheng Technology announced that the company's stock had a cumulative deviation value of more than 20% in closing prices for three consecutive trading days from December 9 to 11, 2025, which is considered abnormal volatility. The stock had five consecutive limit up days in the six trading days from December 5 to 12, with a total increase of 65.94%. The company's controlling shareholder, Guo Mao, is planning to transfer part of the shares through an agreement, but relevant procedures still need to be completed, with uncertainties remaining. The revenue from efficient energy-saving materials used in the aerospace field accounted for approximately 0.5% of the company's total revenue in 2024, and the business income from "high silicon oxygen fiber products" supplied to a certain international aerospace company is very low with no current orders in hand. In addition, the company's price-earnings ratio deviates from the industry average, and the stock turnover rate fluctuates significantly, prompting investors to be cautious of risks.
