Securities fraud, broker misconduct, and investor losses.
Stock market fraud lawsuits cover deceptive practices that mislead investors and cause losses — including misrepresentations in public company disclosures, broker-dealer misconduct, pump-and-dump schemes, insider trading, and Ponzi-style investment fraud.
Common types of stock market fraud.
Recurring categories include misrepresentations or omissions in a public company's financial statements, press releases, or SEC filings; pump-and-dump schemes (artificially inflating a stock's price through false promotion, then selling at the peak); insider trading; market manipulation; accounting fraud; and Ponzi or pyramid schemes presented as legitimate investments.
Other claims involve broker-dealer misconduct — unsuitable recommendations, churning, unauthorized trading, misrepresentation of an investment's risks, and failure to disclose conflicts of interest. These typically proceed as individual FINRA arbitrations rather than class actions.
Securities fraud and antifraud rules.
Section 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 are the primary federal antifraud rules. They prohibit material misstatements, omissions, and manipulative or deceptive practices in connection with the purchase or sale of securities. Section 11 of the Securities Act of 1933 provides separate liability for false statements in registration statements.
To pursue a private securities fraud claim, plaintiffs typically must show a material misstatement or omission, scienter (intent or recklessness), reliance, economic loss, and loss causation. The Private Securities Litigation Reform Act (PSLRA) and related rules impose heightened pleading and procedural requirements on these cases.
Securities class actions and shareholder derivative suits.
Many stock market fraud cases proceed as securities class actions, where investors who bought shares during a defined period pursue claims together. A typical case follows a corrective disclosure — earnings restatement, regulatory action, missed projection, or other event — that causes the share price to drop, prompting investigation and litigation.
Shareholder derivative suits are different: they are brought by shareholders on behalf of the company itself, typically against officers and directors for breaches of fiduciary duty, waste of corporate assets, or insider trading. Recovery in derivative suits generally goes to the company, not to individual shareholders.
Regulators and parallel proceedings.
Stock market fraud is also enforced by regulators. The Securities and Exchange Commission (SEC) brings civil enforcement actions and can refer matters for criminal prosecution by the Department of Justice. The Financial Industry Regulatory Authority (FINRA) regulates brokerage firms and registered representatives. State securities regulators enforce state Blue Sky laws.
Private lawsuits often run in parallel with regulatory or criminal proceedings, and the outcome of one can affect the others. Whistleblowers reporting securities violations to the SEC may be eligible for awards under the SEC whistleblower program in qualifying cases.
