The ASM Framework continues to apply stricter surveillance measures on securities exhibiting abnormal price movements or volatility patterns.

Compliance Requirements

  • Trading members must note the inclusion of Diensten Tech Limited in ASM Stage-I and apply appropriate surveillance protocols
  • Enhanced monitoring required for all securities listed in the consolidated ASM list
  • Members must ensure clients are informed about ASM applicability on affected securities
  • Price bands, trade-for-trade settlement, and other ASM-specific restrictions apply as per stage-wise framework guidelines

Important Dates

  • October 15, 2025: Effective date for Diensten Tech Limited’s inclusion in Long-Term ASM Stage-I

  • T+3 basis: Timeline for shifting Stage-IV securities from EQ series to BE series (T being date of circular issuance)

Impact Assessment

Market Impact: Limited immediate impact as only one security is newly added to surveillance. Diensten Tech Limited will face stricter trading conditions including potential price bands and reduced liquidity.

Operational Impact: Trading members must update surveillance systems to monitor DTL under ASM Stage-I parameters. Enhanced disclosure requirements and risk management protocols apply.

Investor Impact: Investors holding or trading DTL must be aware of ASM restrictions which may include reduced trading flexibility, mandatory delivery-based settlement, and tighter price bands. The consolidated ASM list shows ongoing surveillance on multiple securities across different stages, indicating continued regulatory focus on market integrity.

Impact Justification

Only one security (DTL) added to ASM Stage-I with no stage movements; limited immediate market impact but indicates enhanced surveillance for specific security
