Criminal Liability For Cyber Manipulation Of Stock Markets
Criminal Liability for Cyber Manipulation of Stock Markets
Cyber manipulation of stock markets refers to the use of digital tools, platforms, and technology to artificially influence stock prices or trading activity. This includes hacking, spreading false information, automated trading abuse, and market disruption. Such acts are illegal because they undermine market integrity, investor trust, and financial stability.
Key Forms of Cyber Stock Market Manipulation
Spoofing: Placing large buy or sell orders with no intention of executing them to manipulate prices.
Pump and Dump: Using digital platforms to spread false information to inflate a stock price, then selling at a profit.
Algorithmic Exploitation: Exploiting automated trading algorithms to create artificial price movements.
Insider Trading via Cyber Means: Using hacked or leaked confidential information to trade profitably.
Distributed Denial of Service (DDoS) Attacks: Disrupting stock trading platforms to manipulate trading or panic investors.
Legal Grounds for Liability
Securities and Exchange Laws – e.g., SEC regulations (U.S.), SEBI (India), Financial Conduct Authority (UK).
Cybercrime Laws – unauthorized access, hacking, and online fraud.
Criminal Conspiracy and Fraud – coordinated efforts to manipulate stock prices.
Penalties – fines, disgorgement of profits, imprisonment, and bans from trading.
