On October 13, BIOCYTOGEN-B fell 6.44% in regular trading, trading at HK$58.45 with turnover of HK$13.992 million. The decline was driven by heavy institutional selling, as A-share Dragon-Tiger list data from October 12 showed institutional seats occupying the top four sell positions with combined sales exceeding RMB 180 million, significantly dampening market sentiment and spilling over to Hong Kong trading.
Equity disclosures further revealed divergent institutional behavior between September and October, including multiple rounds of buying and selling by Fullgoal Fund and CMB International. Notably, CMB International and related entities executed a series of off-exchange disposals on September 17 and September 22, reducing their long positions from 9.91% to 6.99%. The concentration of institutional exits has amplified short-term volatility in the stock.
