Rule 10b-5 Fraud
SEC Rule 10b-5
The rule
Securities fraud requires a material misrepresentation or omission, scienter, in connection with a purchase or sale, reliance (presumed for public misstatements under fraud-on-the-market), economic loss, and loss causation; insiders must disclose or abstain when trading on material nonpublic information.
In plain English
Rule 10b-5 prohibits fraud in connection with the purchase or sale of securities. To prove a violation, a plaintiff must show that there was a significant false statement or omission, the defendant acted with intent to deceive, the plaintiff relied on the misrepresentation, and suffered a financial loss as a result.
Worked example
A company executive learns that their company will soon announce a major merger that will significantly increase its stock price. Before the announcement, the executive sells their shares without disclosing this information. After the merger is announced, the stock price soars, and the executive's actions are investigated, leading to a finding of securities fraud.
Memory hook
No secrets in the stock market: disclose or abstain!
The trap
Exams often include scenarios where students must distinguish between mere puffery and material misrepresentations, which can be tricky. Additionally, students may confuse reliance with the requirement of economic loss.
How examiners test it
Questions typically present fact patterns involving insider trading or misleading statements about a company's financial status, requiring candidates to identify elements of fraud and the implications of non-disclosure.
