1. What Constitutes Insider Trading under Federal Law?
Insider trading occurs when a person trades securities on the basis of material nonpublic information in breach of a duty of trust or confidence owed to the source of that information. The prohibition derives from Section 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5. There is no single statute that explicitly defines insider trading; liability is developed through case law interpreting those provisions and related statutes.
These elements describe classical and misappropriation cases under Section 10(b) and Rule 10b-5. Charges under Rule 14e-3, 18 U.S.C. §1348, or other federal statutes may require different proof.
What Are the Two Principal Theories of Insider Trading Liability?
The classical theory applies when a corporate insider trades on material nonpublic information obtained by virtue of their position, breaching a duty to the corporation's shareholders. The misappropriation theory, confirmed in United States v. O'Hagan, 521 U.S. 642 (1997), extends liability to outsiders who trade on confidential information misappropriated in breach of a duty to the source. A lawyer, banker, or adviser who receives client information and trades on it may face misappropriation liability even without a relationship to the issuer.
Can You Face Insider Trading Charges without Trading Personally?
Yes. Under Dirks v. SEC, 463 U.S. 646 (1983), a tipper who discloses material nonpublic information in breach of a duty for a personal benefit may be liable even without trading. In a Rule 10b-5 civil case, tippee liability generally requires proof that the tipper disclosed in breach of a duty for a personal benefit and that the tippee knew or should have known of the breach. A criminal prosecution requires proof of the mental state required by the charged statute beyond a reasonable doubt. The Supreme Court clarified in Salman v. United States, 580 U.S. 39 (2016), that providing a trading tip as a gift to a family member or friend satisfies the personal benefit requirement.
2. How Do the Standards Differ between an Sec Civil Action and a Doj Criminal Case?
The proof requirements and potential consequences differ significantly depending on whether the matter is civil or criminal. The forum also affects discovery, privilege issues, available remedies, and the consequences of providing testimony or documents.
| Issue | SEC Civil Action | DOJ Criminal Case |
|---|---|---|
| Burden of proof | Preponderance of the evidence | Beyond a reasonable doubt |
| Mental state | Scienter; recklessness may suffice under the governing circuit | Knowledge and willfulness under the charged statute |
| Potential result | Disgorgement, civil penalties, injunctions, or officer-director bars | Imprisonment, criminal fines, forfeiture, or restitution |

What Makes Information Material and Nonpublic?
Information is material if a reasonable investor would consider it important or if disclosure would significantly alter the total mix of available information. Pending earnings results, merger negotiations, regulatory approvals, and major litigation developments are recurring examples. Information remains nonpublic until effectively disseminated through channels reasonably designed to reach the market.
3. What Are the Federal Penalties for Insider Trading?
Federal exposure depends on the statute charged, the number of counts, the gain attributed to the offense, and whether parallel SEC relief is pursued. Statutory maximums do not determine the sentence or civil penalty in an individual case.
What Are the Criminal Penalties?
A willful violation charged under the Exchange Act may carry up to 20 years in prison and a fine of up to $5 million for an individual, or $25 million for a non-natural person, under Securities Exchange Act §32(a). DOJ may also charge securities fraud under 18 U.S.C. §1348, which carries a maximum term of 25 years. The applicable maximum depends on the counts and statutes charged.
Under USSG §2B1.4, the advisory offense level is principally driven by the gain resulting from the offense, together with applicable adjustments. The court must also consider the sentencing factors under 18 U.S.C. §3553(a), so the guideline range does not determine the sentence by itself.
What Are the Civil Penalties?
The SEC may seek disgorgement of net profits or losses avoided, subject to applicable equitable limitations, together with prejudgment interest. Civil monetary penalties of up to three times the profit or loss avoided may be sought under Exchange Act §21A. The SEC may also pursue injunctions and bars from serving as a public company officer or director. Broker-dealer or investment adviser registrations may be suspended or revoked.
4. What Defense Strategies Are Available?
Available defenses depend on the source of the information, the duty allegedly breached, the timing of the trade, and the required mental state. A defense must be evaluated against the specific civil or criminal theory asserted.
How Does Lack of Scienter Serve As a Defense?
The required mental state depends on the proceeding. In a Rule 10b-5 civil action, the SEC must prove scienter, and sufficiently reckless conduct may qualify under the governing circuit. In a criminal case, DOJ must prove the knowledge and willfulness required by the charged statute beyond a reasonable doubt. Evidence of independent research, a pre-existing investment rationale, or reliance on publicly available information is relevant to both. Evidence that the defendant relied in good faith on legal advice may also be relevant, but it is not an automatic defense. Raising reliance on counsel may place otherwise privileged communications at issue and requires careful analysis before disclosure.
How Can Independent Research Rebut an Mnpi Allegation?
A trader who lawfully assembles public information may reach the same trading conclusion that material nonpublic information would support without incurring liability under Rule 10b-5. Establishing this requires documenting the research process, identifying the sources relied upon, and showing that no material nonpublic component formed the basis of the trading decision. This approach is a factual argument rather than a formal affirmative defense.
How Does a Rule 10b5-1 Trading Plan Function As a Defense?
Rule 10b5-1 provides an affirmative defense when, before becoming aware of material nonpublic information, a trader enters into a qualifying binding contract, gives trading instructions to another person, or adopts a written trading plan. For directors and Section 16 officers, the cooling-off period generally ends on the later of 90 days after adoption or modification and two business days after the issuer files the Form 10-Q or Form 10-K covering the fiscal quarter in which the arrangement was adopted or modified, subject to a 120-day maximum. The trader must also act in good faith with respect to the plan's operation throughout its term.
5. How Does a Federal Insider Trading Investigation Proceed?
An insider trading investigation may originate from SEC market surveillance, an exchange or FINRA referral, a whistleblower complaint, corporate self-reporting, public information, or a parallel law-enforcement inquiry. The SEC's Market Abuse Unit uses quantitative tools to identify unusual trading patterns before material announcements.
What Happens after an Sec Subpoena or Wells Notice?
A formal order of investigation authorizes designated staff to issue subpoenas and take testimony. A Wells Notice advises the recipient that staff has made a preliminary determination to recommend an enforcement action. Under the SEC Enforcement Manual updated in February 2026, a Wells Notice recipient will ordinarily receive four weeks to make a Wells Submission. The submission allows the recipient to address the staff's preliminary recommendation before the Commission determines whether to authorize an enforcement action. Because statements made during an SEC investigation may be used in subsequent criminal proceedings, legal representation before responding to any inquiry is essential.
6. How Can an Attorney Help in an Insider Trading Matter?
Counsel can assess the information at issue, the nature of any duty implicated, the defendant's trading history and research record, and the likely direction of any governmental inquiry. In securities enforcement matters, early engagement allows for document preservation, identification of potential witnesses, evaluation of Wells Submission strategy, and coordination between parallel civil and criminal proceedings.
Cases involving Rule 10b5-1 plans, corporate governance compliance reviews, or company responses to an SEC investigation require analysis of whether existing procedures satisfy current requirements and what remediation steps are available. An insider trading matter may require coordinated analysis of regulatory exposure, criminal liability, privilege, forfeiture, D&O coverage, and professional licensing consequences.
