$TOUYUN BIOTECH(01332.HK)

In recent days, Touyun Biotech (01332.HK) has experienced a "roller coaster" market trend—after a continuous surge in stock price with high trading volume, it closed with a sharp drop today, down by as much as 24%.

Key review of the volatility: Over the past two weeks, the stock price had been "lying flat" at HK$0.159 with minor fluctuations. Suddenly, it surged with heavy volume over two days, reaching a peak of HK$0.53, only to plunge from the high today, setting a record trading volume.

What happened behind the scenes? The company disclosed in late October to early November that it had signed strategic cooperation agreements with several companies, committing to purchase at least RMB 1 billion worth of products like chitosan fiber (Chlamydomonas reinhardtii) between 2026 and 2028, sparking market expectations of business expansion. This directly ignited short-term speculative sentiment, driving the stock price up nearly 9 times. Interestingly, the company also clarified in the announcement: operations are normal, with no knowledge of the recent stock price fluctuations and no undisclosed major events.

Impact & Risk Warning: On one hand, positive expectations fueled capital inflows; on the other, major holders suddenly cashed out heavily, creating an exceptionally risky trend. The company itself showed no abnormalities, indicating this was more driven by capital and market sentiment.
