Insider Trading Cases
What is Insider Trading?
Insider trading occurs when someone trades in the securities of a company while possessing material, non-public information about the company. This practice is considered illegal because it gives an unfair advantage to insiders over regular investors, undermining market integrity.
Key Elements of Insider Trading:
Insider: Person with access to confidential information (company executives, employees, directors, or even outsiders like lawyers, consultants).
Material Information: Information that can influence an investor’s decision to buy or sell securities.
Non-public: Information not yet released to the general market.
Trading: Buying or selling securities based on such information.
Breach of Duty: Insider has a fiduciary or similar duty to keep information confidential.
Laws Governing Insider Trading:
In India: SEBI (Prohibition of Insider Trading) Regulations, 2015.
In the US: Securities Exchange Act, 1934, Rule 10b-5.
Penalties include fines, disgorgement of profits, and imprisonment.
