NSE has shortlisted five securities under the Long-Term Additional Surveillance Measure (ASM) Framework Stage I effective May 07, 2026, via Circular Ref. No. 331/2026 (Download Ref No: NSE/SURV/74085). A 100% margin requirement will apply from May 11, 2026 on all open positions as of May 08, 2026 and on all new positions created from May 11, 2026 onwards. No securities were placed in Stage IV, and there are no inter-stage movements in this update.

Key Points

• Five securities added to Long-Term ASM Framework Stage I w.e.f. May 07, 2026
• 100% margin applicable on open positions (as on May 08, 2026) and new positions from May 11, 2026
• No securities in Stage IV; no Stage I→II, II→III, or I→IV movements in this circular
• SADBHIN (Sadbhav Infrastructure Project Limited) satisfies the inclusion criteria at BSE
• ASM framework operates in conjunction with all other prevailing surveillance measures
• Shortlisting is purely for market surveillance and should not be construed as adverse action against any company

Regulatory Changes

This circular references and builds upon earlier ASM circulars: NSE/SURV/39265 (Oct 27, 2018), NSE/SURV/45111 (Jul 22, 2020), NSE/SURV/46557 (Dec 04, 2020), NSE/SURV/48506 (Jun 04, 2021), NSE/SURV/52090 (Apr 22, 2022), NSE/SURV/63362 (Aug 09, 2024), and NSE/SURV/64066 (Sep 20, 2024). Securities meeting Criteria VII (Stage IV) would additionally be shifted from Rolling Settlement (Series: EQ) to Trade-for-Trade segment (Series: BE); however, no securities qualify under this criterion in the current update.

Impact Assessment

Affected Securities (Long-Term ASM Stage I from May 07, 2026):

The 100% margin requirement substantially increases the cost of holding or initiating positions in these securities, which is likely to reduce liquidity and trading volumes. Existing position holders face increased margin calls effective May 11, 2026. Retail and leveraged traders are most directly affected. The ASM designation signals heightened regulatory scrutiny due to surveillance-triggered criteria, though NSE explicitly clarifies this does not reflect adversely on the company’s fundamentals.
