In a move aimed at strengthening market discipline and protecting retail investors, the Securities and Exchange Board of India (SEBI) and stock exchanges have announced a revised framework for the Enhanced Surveillance Mechanism (ESM), specifically targeting companies with a market capitalization below ₹1,000 crore. The updated norms came into effect on July 28, 2025, and currently apply to 28 listed firms.
Under the revised mechanism, companies will now be monitored based on a three-month positive price trend and a price-to-earnings (PE) ratio that exceeds twice the Nifty 500 index’s PE ratio. These new parameters aim to detect unusual price movements and valuation anomalies that may indicate speculative trading, often driven by short-term hype or manipulation.
Companies falling under Stage 1 of the ESM framework will be subjected to 100% margin requirements, making it costlier for traders to take leveraged positions. Additionally, these stocks will be placed in a trade-for-trade settlement cycle, which disallows intraday trading and requires the delivery of shares with each transaction. Tight price bands will also be enforced to curb extreme volatility.
Market experts see this move as a necessary step to enhance market integrity and prevent unwarranted price rallies in small-cap stocks, which are often vulnerable to speculative activity and misinformation. Such volatility not only misguides investors but can also destabilize broader market sentiment.
SEBI’s initiative reflects a growing concern about the influx of retail investors into smaller, lesser-known stocks in pursuit of quick gains. The new surveillance criteria will act as an early warning system, allowing exchanges to flag and control risks more proactively.
While some investors may view the stringent measures as restrictive, regulators believe these actions are crucial for long-term market stability. The focus is not on punishing firms, but on maintaining transparency and investor confidence, especially in segments that are more susceptible to manipulation.
The revised ESM framework marks a significant evolution in SEBI’s regulatory oversight, aligning with its broader mission to foster a fair, orderly, and resilient securities market. As the Indian equity landscape continues to broaden, such measures will play a pivotal role in ensuring that growth is built on a foundation of integrity and trust.
