In Dirks v. SEC, decided in 1983, the Supreme Court ruled that a person who trades on a tip cannot be held liable for insider trading unless the insider who leaked the information breached a fiduciary duty by disclosing it for personal benefit, and the tippee knew or had reason to know of that breach.1 The decision rejected the SEC’s broader theory that anyone holding material nonpublic information had to either disclose it publicly or stay out of the market, and it set the framework that still governs tippee liability today.
The Case That Produced the Rule
Raymond Dirks was a securities analyst at a New York broker-dealer who covered insurance stocks. In 1973, Ronald Secrist, a former officer of Equity Funding Corporation of America, told Dirks that the company was inflating its assets with fabricated insurance policies. Dirks flew to Los Angeles, interviewed employees, reviewed records, and confirmed the fraud.
He tried to get the Wall Street Journal to publish the story. The paper hesitated. In the meantime, Dirks discussed what he had found with clients and institutional investors. Five investment advisers who heard his reports unloaded more than $16 million in Equity Funding stock. Over the two weeks of his investigation, the share price fell from $26 to under $15, and the New York Stock Exchange eventually halted trading. Dirks himself never bought or sold a share.
The SEC investigated, and rather than focus on the underlying corporate fraud, it went after Dirks as the conduit. The agency censured him for repeating the allegations to investors before any public announcement, and the D.C. Circuit affirmed. The Supreme Court reversed.
What the SEC Had Argued
The SEC charged Dirks with aiding and abetting violations of Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5. Its theory was the “disclose or abstain” rule: anyone possessing material nonpublic information had to either publish it or refrain from trading. Under that view, a tippee automatically inherited the insider’s obligations the moment confidential information changed hands. Motive did not matter. Whether the insider profited did not matter. Possession was enough.
The Personal Benefit Test
Justice Lewis Powell, writing for the majority, rejected that theory. The Court held that a tippee’s liability is derivative: it exists only if the insider first breached a fiduciary duty to shareholders. And an insider breaches that duty by tipping only when the insider “receives a direct or indirect personal benefit from the disclosure, such as a pecuniary gain or a reputational benefit that will translate into future earnings.”
The Court also treated gifts as a form of personal benefit. Giving confidential information to a trading relative or friend counts, because “the tip and trade resemble trading by the insider himself followed by a gift of the profits to the recipient.” Without some form of gain to the insider, there is no breach, and without a breach there is nothing for the tippee to inherit.
Applied to Dirks, the answer followed immediately. Secrist and the other Equity Funding employees were whistleblowers. They got no money, no trading profits, no reputational payoff. They tipped Dirks to expose a fraud that auditors and regulators had missed. Because they did not act for personal benefit, they did not breach a duty, and Dirks could not be liable for passing along what they told him.
The Court also grounded the rule in how markets work. Analysts contribute to accurate pricing by digging up information about public companies. A rule punishing anyone who traded on nonpublic information would chill legitimate research and discourage the investigation of corporate misconduct. The personal benefit test separates corrupt tipping from the ordinary flow of information that keeps markets honest.
When a Tippee Is Liable After Dirks
After Dirks, tippee liability under Rule 10b-5 requires two things:
- The insider breached a fiduciary duty by disclosing confidential information for personal benefit.
- The tippee knew, or had reason to know, that the disclosure was a breach.
If either element is missing, the tippee is not liable. The knowledge requirement carries most of the weight in chain-of-tippers cases. When information moves through several hands before reaching the trader, the government still must show that the final trader understood the information originated in a breach of duty. The further removed the trader is from the source, the harder that showing becomes.
The personal benefit element also shifts the inquiry away from the tippee’s profits. A trader who earns millions on a tip is not liable if the insider shared the information innocently. A trader who barely profits can be sanctioned if the insider clearly tipped for gain and the trader knew it. The focus stays on corruption at the source.
How Newman and Salman Reshaped the Test
The gift branch of the personal benefit test generated years of disagreement in the lower courts. Two decisions define the current landscape.
United States v. Newman (2014)
The Second Circuit tightened the standard in United States v. Newman, holding that the personal benefit had to be “objective, consequential, and represent at least a potential gain of a pecuniary or similarly valuable nature.” When prosecutors relied on a gift theory, the court required proof of a “meaningfully close personal relationship” between tipper and tippee. Newman also demanded that remote tippees know the specific benefit the original insider received, which made downstream prosecutions considerably harder.
Salman v. United States (2016)
The Supreme Court pushed back in Salman v. United States, involving a Citigroup investment banker who fed deal information to his brother, who passed it to a brother-in-law. A unanimous Court reaffirmed Dirks and held that a gift of confidential information to a trading relative or friend satisfies the personal benefit requirement on its own, with no further showing of pecuniary gain. The Court called Newman‘s demand for “something of a pecuniary or similarly valuable nature” in gift cases “inconsistent with Dirks.”
The Second Circuit followed up in United States v. Martoma and dropped the “meaningfully close personal relationship” requirement, holding that a gift of inside information can establish personal benefit even outside close family or friendship ties. The upshot: the Dirks framework remains intact, and the gift prong is broader than Newman had suggested. Prosecutors do not need to show cash or a tangible kickback when the tip functions as a gift, but they still must prove the insider received some benefit and the tippee knew about the breach.
What Dirks Does Not Cover
Dirks addressed what courts call the “classical theory” of insider trading, in which a corporate insider (or a tippee of one) trades in breach of a duty owed to the company’s shareholders. It does not reach corporate outsiders who steal confidential information from a source they owe a duty to and trade on it.
That gap was filled in United States v. O’Hagan (1997), where the Supreme Court endorsed the “misappropriation theory.” Under that theory, a person violates Section 10(b) and Rule 10b-5 by taking confidential information for securities trading in breach of a duty owed to the source of the information, rather than to the shareholders of the traded company. The Court described this as “fraud akin to embezzlement.” A lawyer at an outside firm who learns of a pending merger through client work owes no duty to the target’s shareholders, so Dirks would not reach that lawyer’s trading; the misappropriation theory does, because the lawyer owes a duty to the firm and its client.
One wrinkle unique to the misappropriation theory: if the outsider tells the source they plan to trade, there is no “deceptive device” and no violation. The fraud is the secret use of the information, not the trade itself. That disclosure defense has no equivalent in the classical Dirks framework, where an insider cannot simply announce plans to trade on confidential information and walk away.
