GIGADEVICE is trading 4.15% down at HK$494.60 after reversing part of its sharp August 27 rebound, with no fresh company-specific negative catalyst identified in available August 28 coverage.

  • An August 27 announcement of a RMB101 million A-share buyback supported the previous session’s gains.
  • Earlier reporting highlights volatility in memory and semiconductor stocks, but does not directly explain this session’s decline.
