SEBI and Stock Exchanges Revise Surveillance Framework for Small-Cap Firms

The Securities and Exchange Board of India (SEBI), in collaboration with stock exchanges, has announced a revision to the Enhanced Surveillance Mechanism (ESM) for companies with a market capitalisation below ₹1,000 crore, effective from July 28, 2025. The move aims to improve the monitoring of small-cap and micro-cap stocks, reduce speculative activity, and enhance investor protection. The revision will directly benefit 28 companies currently under the surveillance framework.

Objective of the Revision

The revised framework seeks to strike a balance between encouraging growth in the small-cap segment and preventing excessive volatility. Since small and micro-cap stocks are often more vulnerable to price manipulation and speculative trading, SEBI’s new rules are designed to ensure greater market integrity and transparency while safeguarding retail investors.

New Shortlisting Parameters under Stage 1

Earlier, companies were brought under surveillance mainly due to high-low price variations. The revised framework adds a new filter by considering a consistent positive close-to-close price trend over the last three months. This ensures that stocks showing sustained price appreciation, often a signal of heightened investor interest, are closely monitored to avoid speculative build-ups.

Stage 2 and the PE Ratio Threshold

To qualify for Stage 2 surveillance, a new price-to-earnings (PE) ratio limit has been introduced. A stock must now have a PE ratio not exceeding twice that of the Nifty 500 index to move into Stage 2. This measure ensures that overvalued stocks do not bypass stricter monitoring, protecting investors from potential risks linked with inflated valuations.

Trading Restrictions for Stage 1 Companies

Stocks placed under Stage 1 of the ESM framework will face tighter trading conditions. These include a 100% margin requirement starting from T+2 days, a trade-for-trade settlement mechanism, and a 5% price band. In cases where a stock already operates under a 2% price band, that restriction will continue, ensuring no relaxation in control over highly volatile shares.

Background of the ESM Framework

The Enhanced Surveillance Mechanism was first extended to listed companies with market capitalisation below ₹1,000 crore in August 2023. It was introduced to curb excessive price volatility and protect retail investors from market manipulation. SEBI and the stock exchanges conduct weekly reviews to decide whether to keep a stock under surveillance, downgrade it to a lower stage, or remove it from the framework altogether.
