The elevated margin requirement (minimum 50%) will reduce leveraged trading capacity in these 13 securities, likely dampening short-term speculative activity and potentially causing selling pressure as traders reduce positions to meet margin calls. Retail investors using margin financing in these stocks will be most directly affected. PURVA (Puravankara Limited) is the most widely tracked name in this list given its presence in the real estate sector.
Impact Justification
Directly affects trading conditions for 13 listed securities by imposing elevated margin requirements; traders holding or initiating positions in these stocks must comply by April 20, 2026 or face regulatory risk.
