BSE imposes Long Term Additional Surveillance Measures (LT-ASM) on specific securities. The exchange applies 100 percent margins on open positions as of August 14, 2026, and on new positions from August 17, 2026. Certain securities move to higher LT-ASM stages or transfer to T, XT, MT, or TS groups effective August 17, 2026. The exchange applies lower price bands to identified securities starting August 13, 2026. Other securities exit the LT-ASM framework effective August 13, 2026, and return to their previous price bands. These measures apply in addition to existing surveillance requirements. The exchange reviews these securities periodically. This action results from market surveillance and does not constitute adverse action against the listed entities.
