SEBI has prohibited two entities from the securities market for allegedly manipulating stock derivative prices through cross-derivatives trading. The entities reportedly used coordinated, sophisticated trading strategies to artificially influence derivative prices across linked instruments. SEBI's interim order restricts them from buying, selling, or dealing in securities pending investigation. The action reflects SEBI's intensified surveillance of derivatives markets, where manipulation can distort price discovery and harm retail investors who rely on fair pricing.

Cross-derivatives manipulation involves coordinating trades across related derivative instruments — such as futures and options on the same underlying stock — to create artificial price movements that benefit the manipulator's positions. Unlike straightforward pump-and-dump schemes in equities, cross-derivatives manipulation is harder to detect because it exploits pricing relationships between instruments rather than simply pushing a single security's price.

SEBI's enforcement toolkit for such cases includes interim orders under Section 11(4) of the SEBI Act, 1992, which allows the regulator to restrain entities from accessing markets without a full adjudication hearing, provided there is a prima facie case of fraud or market manipulation. This is distinct from a final order or a show-cause notice — it is a preventive measure to stop ongoing harm.

The underlying legal framework includes the SEBI (Prohibition of Fraudulent and Unfair Trade Practices) Regulations, 2003 (PFUTP Regulations), which prohibit market manipulation, creation of false trading appearance, and price rigging. SEBI also uses the SEBI (Prohibition of Insider Trading) Regulations, 2015, when information asymmetry is involved.

For exam purposes, the key concepts are: (1) SEBI's interim order power under Section 11(4); (2) PFUTP Regulations as the primary anti-manipulation framework; (3) derivatives market surveillance mechanisms; and (4) the distinction between interim, ex-parte, and final enforcement orders. SEBI has been escalating derivatives market oversight, particularly after the F&O trading volumes surged dramatically post-2020.
