CMBC Capital Holdings is trading 12.1% up at HK$0.69; no confirmed company-specific catalyst was identified for the September 28 move.

  • The latest reported buyback was 480,000 shares for HK$285,700 on September 23, before this session; it does not establish a cause.
  • The Hang Seng Index rose 0.54% on September 28, but that market move does not explain the stock’s larger gain.
