Penny Stock (SEBI Definition)
In the Indian regulatory context, SEBI and exchanges identify penny stocks through surveillance frameworks as shares trading at very low absolute prices—typically below ₹10—with low market capitalisation, thin volumes, and a history of price manipulation, subjecting them to enhanced scrutiny and trading restrictions.
The term 'penny stock' is used colloquially across global markets, but in India, SEBI and the stock exchanges have operationalised the concept through specific regulatory actions rather than a single formal statutory definition. The Graded Surveillance Measure (GSM) and Additional Surveillance Measure (ASM) frameworks are the primary mechanisms through which low-quality, potentially manipulated stocks are identified and subjected to restrictions.
Under the GSM framework introduced by SEBI in 2017, stocks are moved to enhanced surveillance stages based on a combination of factors: very low market capitalisation, high price-to-earnings ratios (or negative earnings), trading solely on price-to-book metrics disconnected from fundamentals, and unusual price or volume movements. Stocks placed in higher GSM stages can only be traded in a trade-to-trade (T2T) segment where delivery is mandatory and intraday squaring-off is not permitted. At the highest GSM stages, trading frequency is restricted to once a week or once a month.
Regulatory actions against penny stock manipulation have been a recurring theme in SEBI enforcement orders. Common manipulation patterns include 'pump and dump' schemes—where a group of connected persons artificially inflates a low-priced stock through circular trading, simultaneously spreading positive rumours through social media and messaging platforms, and then exits after retail investors are drawn in. SEBI's investigations have established cases involving hundreds of shell companies, fake financial results, and co-ordinated social media campaigns.
From an investor protection standpoint, SEBI's surveillance systems generate alerts for stocks showing characteristics associated with manipulation: sudden price surges without corresponding corporate announcements, extreme concentration of trading in a small number of entities, and disconnect between price movement and market-wide trends.
Investors should be aware that the GSM and ASM designations are publicly disclosed on NSE and BSE websites, and reviewing these lists before transacting in unfamiliar low-priced stocks is a basic due diligence step.
