Market Abuse Investigations.
1. Introduction to Market Abuse Investigations
Market Abuse Investigations are legal and regulatory processes aimed at identifying and addressing manipulative, deceptive, or unfair practices in financial markets. These investigations are designed to protect investors, maintain market integrity, and ensure confidence in capital markets.
Market abuse typically includes:

- Market manipulation: Artificially influencing prices or trading volumes.
- Misleading statements: Dissemination of false or misleading information affecting investment decisions.
- Front-running or spoofing: Exploiting advance knowledge of pending orders or creating false trading signals.
Investigations are conducted by regulators such as:
- SEBI (India) – Securities and Exchange Board of India.
- FCA (UK) – Financial Conduct Authority.
- SEC (US) – Securities and Exchange Commission.
- ESMA (EU) – European Securities and Markets Authority.
