Dian Swastatika Sentosa is trading at IDR 965, down 14.6% on October 12, 2026, amid unconfirmed rumors authorities could sanction issuers and securities firms over suspected stock-price manipulation.

  • Rumors were linked to MSCI’s Indonesia market review, but MSCI cannot impose issuer fines; the investigation remains ongoing.
  • Thin free float and concentrated ownership made affected stocks vulnerable; geopolitical concerns and foreign selling added pressure. No reliable source tied the decline to a company-specific event or confirmed rumors as the sole cause.
