The exclusions from ASM represent an easing of surveillance restrictions for most affected securities, which may improve liquidity and reduce margin requirements for those stocks. The addition of WINNY to Stage I signals increased regulatory scrutiny due to unusual price/volume activity.

Impact Justification

Routine ASM framework update affecting a limited number of securities with stage changes and exclusions; impacts trading conditions for specific stocks but is a regular surveillance action.
