Impact Assessment
High impact on affected securities: The inclusion of securities in ESM framework significantly impacts trading liquidity and capital requirements. The 100% margin requirement substantially increases capital costs for traders and investors holding positions in these securities. The shift to trade-for-trade settlement eliminates intraday trading opportunities, further reducing liquidity.
Stage-II implications: SALSTEEL’s movement to Stage-II represents escalated surveillance with the additional constraint of 2% price band under Periodic Call Auction, severely restricting price volatility and trading flexibility.
Investor considerations: The exchange clarifies that ESM inclusion is purely a market surveillance measure and should not be construed as adverse action against the companies. However, investors should exercise heightened caution and conduct thorough due diligence before trading in these securities.
Capital allocation: Market participants with existing positions must arrange for additional capital to meet the 100% margin requirement by February 10, 2026, or face potential position squaring-off.
Impact Justification
High importance due to mandatory 100% margin requirement and shift to trade-for-trade segment affecting trading liquidity and capital requirements for impacted securities
