In a civil lawsuit alleging a violation of the anti-fraud provisions of the Securities Exchange Act of 1934, also known as a Rule 10b-5 violation, the plaintiff must prove by a preponderance of the evidence:

The defendant used an instrumentality of interstate commerce in connection with the securities transaction.
The defendant made a false representation of a material fact (or omitted a material fact) in connection with the purchase or sale of a security.
The defendant acted knowingly or with severe recklessness.
The plaintiff justifiably relied on the defendant’s conduct.
The plaintiff suffered damages as a proximate result of the defendant’s wrongful conduct.

This first installment focuses on interstate commerce and the foundation of securities fraud law.

The Securities Exchange Act of 1934: Why It Was Enacted

Before 1934, stock markets operated with little regulation, leading to:

Lack of transparency about company finances.
Widespread manipulation of securities markets.
Insider trading and unchecked fraud.

The Securities Exchange Act of 1934 addressed these issues by:

Creating the Securities and Exchange Commission (SEC) to regulate markets.
Requiring companies to register securities and disclose accurate financial information.
Prohibiting manipulative and deceptive practices.

Rule 10b-5: The Cornerstone of Securities Fraud Cases

Section 10(b) of the Act (15 U.S.C. § 78j(b)) prohibits any manipulative or deceptive device in the purchase or sale of securities. Rule 10b-5(b) specifically makes it unlawful to commit fraud in connection with such transactions.

Plaintiffs may bring a civil action for damages if they can prove a violation.

The First Element: Use of an Instrumentality of Interstate Commerce

To succeed under Rule 10b-5, a plaintiff must prove the defendant used an instrumentality of interstate commerce in connection with the transaction.

This can include:

Telephone, Internet, email, or mail.
Interstate delivery services (e.g., FedEx, UPS).
Facilities of a national exchange (NYSE, NASDAQ).
Electronic trading systems in the over-the-counter market.

Importantly, the fraud does not need to be transmitted through these means. It is enough if interstate commerce was used at any stage of the transaction.

What Counts as a Security?

The definition of “security” is critical. A security is generally an investment in a business or financial enterprise with the expectation of profits from others’ efforts.

Common securities include:

Stocks
Bonds
Debentures
Warrants
Investment contracts

Courts often decide whether an investment qualifies as a security as a matter of law.

Why “Internet Much?” Matters in Securities Fraud

In today’s financial markets, nearly all securities transactions use the Internet, electronic communications, or exchange facilities. Even if fraud occurs offline, use of email, electronic transfers, or trading systems satisfies the interstate commerce requirement under Rule 10b-5.

Conclusion: Why Interstate Commerce Matters in Rule 10b-5 Cases

The requirement of using an instrumentality of interstate commerce is broad, ensuring federal jurisdiction applies to almost all securities transactions. Plaintiffs in a Securities Fraud Rule 10b-5 case must carefully establish this element before moving on to other requirements like misrepresentation, reliance, and damages.
