HoSE has restricted margin trading for 56 securities in August, including DQC and 12 other stocks under warning, supervision, trading restriction or suspension.
Margin trading restrictions reduce leverage availability for affected securities, constraining speculative capital flows and potentially limiting intraday price discovery for DQC and peers classified under regulatory oversight. The restriction affects multiple sectors—banking (APH), real estate (LDG, DGC), aviation (HVN), and energy (OGC)—each relying on margin financing for liquidity provision.
