Trading on unpublished information.
Dealing in securities while in possession of unpublished price sensitive information.
Statutory Definition
SEBI (Prohibition of Insider Trading) Regulations.
Etymology & Origin
'Insider' from 'inside' — a person who is within, with access to internal or confidential information. 'Trading' from Old English 'tredan' (to tread, to walk), later developing the commercial sense of 'trading' (a course of dealing). Insider trading, in its prohibited sense, denotes dealing in securities by a person in possession of confidential, price-sensitive information not available to the market at large. The prohibition reflects the principle that the securities market must be a level playing field, and that those with privileged access to information must not exploit it against the ordinary investor.

Insider Trading: The Exploitation of Privileged Information
A fundamental premise of a fair securities market is that all investors should have equal access to material information about the securities they trade. Insider trading strikes at this premise. It occurs when a person — an 'insider', connected with the company or in possession of confidential information — trades in the company's securities while in possession of unpublished price-sensitive information (UPSI), exploiting knowledge that the general market does not have. The practice is prohibited in India, as in most developed markets, both as a civil violation (with penalties and disgorgement imposed by SEBI) and as a serious market abuse that undermines investor confidence.
The Statutory and Regulatory Framework
The prohibition on insider trading in India is articulated through two principal instruments. Section 12A of the SEBI Act, 1992, read with the SEBI (Prohibition of Insider Trading) Regulations, 2015 (as amended), prohibits any person from dealing in securities while in possession of UPSI. The Regulations define the key terms with precision. A 'connected person' is one who is or has been, during the six months preceding the trade, associated with the company — directly or indirectly, in any capacity, including by reason of frequent communication with its officers. A 'trading plan' allows an insider to pre-commit to trades that will be executed mechanically, irrespective of UPSI, providing a safe harbour. UPSIs are defined as information that, if published, would materially affect the price of the securities — results, major expansions, mergers, regulatory actions, change in capital structure.
Theories of Liability and Defences
The Regulations establish liability on two principal theories. First, for connected persons, the possession of UPSI at the time of trading is sufficient to constitute a violation — the connection creates a duty not to trade while in possession, regardless of how the information was used. Second, for non-connected persons ('immediate relatives' and others), liability requires proof that the information was actually communicated to them by an insider and that they traded on it. The principal defences are: (a) the trades were made pursuant to a pre-disclosed, bona fide trading plan; (b) the information was not UPSI (it was already in the public domain, or it was not price-sensitive); (c) the trade was undertaken in the ordinary course of business and the insider could show that the decision was not influenced by the UPSI; (d) the transaction was an intra-family transfer or a gift without consideration. SEBI's enforcement powers include penalties, disgorgement of profits, debarment from the market, and prosecution. The prohibition reflects the larger principle that the integrity of the securities market depends on the equal availability of information to all participants, and that those entrusted with confidential corporate information must not turn that trust to private profit.
“The securities market rests on trust — trust that information is shared, that prices reflect what is known, that no player holds a hidden card. Insider trading is the betrayal of that trust: the exploitation of confidential knowledge for private gain at the expense of the ordinary investor. The law's prohibition is the market's shield; without it, confidence would wither, and the market with it.”
