On August 19, JOINN fell 5.13% in regular trading, trading at HK$25.48/share, with turnover of HK$81.96 million. The decline followed two consecutive days of sharp gains, with the stock rising 6.22% on August 17 and 6.30% on August 18, accumulating significant short-term gains.

Multiple factors contributed to the pullback. The broader CXO sector experienced overall weakness, with peers including Wuxi Biologics down 2.06%, Wuxi AppTec down 1.27%, and Wuxi XDC down 3.15%. Additionally, former Vice Chairman Zuo Conglin disclosed on August 13 a planned reduction of up to 3.5245 million shares, with substantial cumulative insider selling pressure weighing on market sentiment.

The company is scheduled to hold a board meeting on August 28 to review interim results for the six months ended June 30. Market participants may be engaging in profit-taking ahead of the earnings release, given the stock had previously rallied on the back of strong half-year profit guidance of RMB 600-900 million and 31 billion yuan in backlog orders as of Q1-end.
