Insider Trading Charges

Insider trading is buying or selling a stock (or tipping someone else to do so) using material, nonpublic information while you're under a duty not to use it that way — for example, because you're a corporate insider, an employee of a law firm or bank working on a deal, or someone who received a tip from a person who breached a duty. It is not automatically illegal just because you knew something the market didn't; the government has to prove a breach of duty and, usually, intent. The same conduct can trigger a civil case from the Securities and Exchange Commission (SEC) and a separate criminal case from the Department of Justice (DOJ), sometimes running side by side, with very different burdens of proof and different things at stake.

What actually has to be proven

There is no single federal "insider trading" statute that lists every element. Instead, insider trading cases are built on the general securities-fraud rule — Section 10(b) of the Securities Exchange Act and SEC Rule 10b-5, which make it unlawful to defraud anyone in connection with buying or selling a security. Courts have applied that broad fraud rule to trading on inside information under two main theories:

• Classical theory: A corporate insider (officer, director, employee) trades in the company's own stock using material nonpublic information, breaching the duty of trust and confidence owed to the company's shareholders.
• Misappropriation theory: Someone who is not a company insider — a lawyer, investment banker, printer, spouse, or friend who was let in on confidential deal information — trades on it anyway, breaching a duty owed to the source of the information (their employer, client, or the person who confided in them) rather than to the company's shareholders.

Both theories require a breach of a duty of trust or confidence, not just possession of an information advantage. Two further concepts matter:

• Material: Information a reasonable investor would consider important to a decision to buy or sell — a pending merger, an earnings miss, a drug trial result, a major contract loss.
• Nonpublic: Information that hasn't been disclosed to the market yet, even if a few people already know it.

Tipper and tippee liability

Liability doesn't stop with the person who first learned the secret. If an insider (the "tipper") passes material nonpublic information to someone else (the "tippee") who then trades on it, both can potentially be liable — and liability can travel down a chain of multiple tippees, as long as each person down the chain knew, or had reason to know, that the information originated from someone who breached a duty by disclosing it.

A key limiting rule: the tipper generally has to have received some personal benefit from disclosing the information for tippee liability to attach — money, a reciprocal favor, career advancement, or even the intangible benefit of making a gift of a "trading tip" to a relative or friend. Simply overhearing something in an elevator or at a dinner party, without that benefit-driven breach, is a different (and much harder) case for the government to make.

What is not illegal

People often assume any information edge is illegal. It usually isn't, unless it was obtained through a breach of duty. Generally lawful conduct includes:

• Trading based on your own research, analysis, or educated predictions about a company, even if you turn out to be right.
• "Mosaic theory" investing — piecing together many small, individually nonmaterial, publicly available or properly obtained data points (store visits, supplier checks, industry surveys) into an investment thesis.
• Trading on rumors or market speculation that didn't come from a corporate or fiduciary source.
• Trades made under a properly structured, pre-set trading plan under SEC Rule 10b5-1 that was adopted in good faith before the person had any material nonpublic information.

The line between aggressive-but-legal "expert network" or channel-check research and illegal tipping is exactly where many real investigations live, which is why these cases are so fact-intensive.

SEC civil case vs. DOJ criminal case

The same trades can produce two separate government actions, and they are not the same thing:

• SEC (civil): The SEC can sue in federal court or bring an internal administrative proceeding. It only has to prove its case by a "preponderance of the evidence" (more likely than not) — a much lower bar than a criminal case. Remedies include disgorgement of profits (or losses avoided), civil monetary penalties (which can be a multiple of the gain), injunctions against future violations, and bars from serving as an officer or director of a public company. The SEC cannot send anyone to prison.
• DOJ (criminal): Federal prosecutors can separately charge securities fraud, wire fraud, or conspiracy. A criminal case requires proof beyond a reasonable doubt, and typically requires proof that the person acted willfully — not by accident or through a good-faith misunderstanding. Criminal exposure includes federal prison time and substantial fines, with the actual sentence shaped by the federal sentencing guidelines and case-specific facts (loss amount, role, cooperation, criminal history). Because the numbers vary enormously case to case, don't rely on any specific figure you read online — ask your lawyer what applies to your facts.

These proceedings can run in parallel, and information given to the SEC in an "informal" interview or in testimony can end up in the hands of criminal prosecutors. That overlap is one of the most important — and most misunderstood — traps in these cases.

Every defendant's baseline rights

Whether the case is civil, criminal, or both, some rights are constant in the American system:

• You are presumed innocent, and in any criminal case the government bears the burden of proving guilt beyond a reasonable doubt — you never have to prove your innocence.
• You have the right to remain silent, and if you are in custody and being questioned by law enforcement, agents must give Miranda warnings before that questioning can be used against you (Miranda v. Arizona, 1966).
• You have the right to an attorney, and if you cannot afford one in a criminal case, the government must provide one (Gideon v. Wainwright, 1963).
• You are entitled to a lawyer who provides effective, competent representation (Strickland v. Washington, 1984).
• Prosecutors have a constitutional obligation to turn over material evidence that could help your defense (Brady v. Maryland, 1963).

These securities cases are almost always investigated by SEC attorneys and FBI agents rather than through a roadside stop, so search-and-seizure or traffic-stop doctrines rarely come up — but the core trial and interrogation rights above apply just the same.

What to do if you're contacted or think you're being investigated

1. Say as little as possible until you have a lawyer. Politely decline to answer substantive questions from SEC staff, FBI agents, or company compliance/HR investigators until you've spoken with counsel — anything you say can be used in both the civil and criminal tracks.
2. Get a securities/white-collar defense lawyer immediately — ideally one with experience in both SEC enforcement and federal criminal securities-fraud defense, since the two tracks require coordinated strategy.
3. Preserve every document and communication. Do not delete texts, emails, trading records, or calendar entries once you know you might be investigated. Destroying or altering evidence can itself become a separate, serious obstruction charge — worse than the underlying trading allegation.
4. Read subpoenas and document requests carefully and note every deadline. SEC subpoenas, "Wells notices" (a formal notice that the SEC staff intends to recommend charges, which typically gives you a limited window to respond in writing before the case is voted on), and grand jury subpoenas all carry real deadlines — some quite short. Missing one can waive your chance to respond before charges are filed. Have your lawyer calendar and respond to each one.
5. Don't talk to co-workers, friends, or family about the substance of the investigation beyond what your lawyer advises — those conversations may not be privileged and can be discoverable.
6. If you're asked to testify to the SEC or a grand jury, discuss the Fifth Amendment with your lawyer first. Whether to testify, and how, is a strategic decision your attorney should help you make in light of the parallel criminal risk.

Time-sensitive things to watch for

Several clocks can be running at once in these cases, and they don't wait for you to get organized:

• Response windows on SEC subpoenas, document requests, and Wells notices are often short — confirm the exact deadline in the letter itself and get counsel involved before it passes.
• Federal criminal charges must generally be brought within a limited statute-of-limitations window — five years for many federal offenses by default, and six years for securities fraud under a separate federal statute — but the exact clock, and when it starts, depends on the specific charges and facts. Don't assume time has run out (or that you're safe) without a lawyer checking the specifics for your situation.
• Once litigation or an investigation is reasonably anticipated, you may have a legal duty to preserve documents (a "litigation hold") — failing to do so can create separate liability even if the underlying trading claim is weak.

Bottom line

Insider trading law turns on whether nonpublic, material information was used in breach of a duty — not merely on whether you had an information edge. If you're contacted by the SEC or federal agents, or you receive a subpoena, treat it as urgent: get a lawyer experienced in securities enforcement and federal white-collar defense before you say or write anything else about the situation.
