The elevated 35% margin requirement increases the cost of carrying or initiating positions in the three newly included securities, which may reduce liquidity and trading volumes in those counters. The nine exclusions provide margin relief to traders and investors holding those securities. The measure is neutral in intent – it is a regulatory risk-management tool and not indicative of any fundamental adverse development at the listed companies.
Impact Justification
Routine periodic surveillance update affecting margin requirements for a defined set of securities; directly impacts trading costs and positions for members holding or trading these stocks in Equity and Equity Derivatives segments.
