Frequently Asked Questions

Understanding Insider Trading

What is insider trading?

Insider trading refers to the buying or selling of a publicly traded company’s securities by someone who possesses material, non-public information (MNPI) about that company. "Material" means the information is significant enough to influence an investor’s decision, and "non-public" means it has not been disclosed to the general investing public. Legal insider trading occurs when insiders trade shares in compliance with SEC regulations and proper disclosure; illegal insider trading involves trading on confidential information not available to others, or passing such information to others who then trade on it. (Source: Shield Glossary, Insider Trading)

Is insider trading always illegal?

No. Insider trading can be legal when corporate insiders—such as executives or directors—trade shares in their own company in compliance with SEC disclosure rules, including filing Forms 3, 4, and 5. It becomes illegal when trades are based on confidential, non-public information that is not available to the public. (Source: Shield Glossary, Insider Trading)

What is material non-public information (MNPI)?

Material non-public information (MNPI) is information that would influence an investor’s decision to buy or sell securities and has not been disclosed to the general market. Examples include earnings results, mergers, regulatory decisions, or major product developments. (Source: Shield Glossary, Insider Trading)

Why is insider trading illegal?

Insider trading is illegal because it undermines market fairness and transparency. Financial markets rely on equal access to information. When some participants trade on privileged knowledge, it distorts prices, disadvantages other investors, and damages trust in the market. (Source: Shield Glossary, Insider Trading)

What is Rule 10b-5 and how does it relate to insider trading?

Rule 10b-5, issued under the Securities Exchange Act of 1934, prohibits fraud in connection with the purchase or sale of securities. It forms the legal foundation for prosecuting insider trading, making it unlawful to use deceptive practices or confidential information for personal gain in securities transactions. Both the classical theory (insiders trading their own company’s securities while breaching fiduciary duty) and the misappropriation theory (outsiders misusing confidential information) are used to establish violations. (Source: Shield Glossary, Insider Trading)

What are some examples of insider trading?

Examples include: (1) A corporate executive selling shares before negative news is made public; (2) A government employee trading on confidential regulatory decisions; (3) A tipper passing MNPI to a tippee who then trades on it. In each case, trading on material non-public information for personal gain or to avoid losses constitutes illegal insider trading. (Source: Shield Glossary, Insider Trading)

What are the consequences of insider trading?

Consequences include civil penalties (up to three times the profit gained or loss avoided), criminal penalties (fines up to million and prison sentences up to 20 years for individuals, million for corporations), and reputational/professional consequences such as permanent bars from serving as officers or directors of public companies. (Source: Shield Glossary, Insider Trading)

Can you go to jail for insider trading?

Yes. Criminal prosecution for insider trading can result in significant prison sentences. For example, Raj Rajaratnam was sentenced to 11 years in prison in 2011, and Samuel Waksal received more than seven years following his guilty plea in 2002. (Source: Shield Glossary, Insider Trading)

Who can be liable for insider trading?

Liability extends beyond corporate executives to anyone who trades on material non-public information obtained through a breach of duty or a confidential relationship. This includes lawyers, consultants, financial analysts, government officials, and even friends or family members of insiders who receive tips. (Source: Shield Glossary, Insider Trading)

Is insider trading only illegal if you make a profit?

No. The law prohibits trading on material non-public information regardless of whether a profit is realized. Using MNPI to avoid a loss is equally actionable. The focus is on the use of the information, not the outcome. (Source: Shield Glossary, Insider Trading)

Does the SEC only act after significant harm has occurred?

No. The SEC actively monitors trading activity in real time using surveillance tools that flag unusual patterns, such as large options purchases ahead of major announcements. The agency can initiate investigations based on anomalous trading data, often before any public complaint is filed. (Source: Shield Glossary, Insider Trading)

Insider Trading

Back To Glossary Page

What Is Insider Trading?

Insider trading refers to the buying or selling of a publicly traded company’s securities, including stocks, bonds, or options, by an individual who possesses material, non-public information (MNPI) about that company. 

“Material” means the information is significant enough that a reasonable investor would consider it relevant to their decision to buy or sell. “Non-public” means it has not yet been disclosed to the general investing public.

The term covers two distinct categories. Legal insider trading occurs when corporate executives, directors, and employees buy or sell shares in their own company, provided they comply with SEC regulations, including proper disclosure filings. Illegal insider trading occurs when those trades are made on the basis of confidential information that other market participants do not have access to, or when such information is passed to a third party who then trades on it.

Insider trading is significant to financial markets because securities markets function on the premise that all participants have equal access to material information. When some traders act on privileged knowledge, it distorts prices, undermines market integrity, and erodes investor confidence. The SEC, which enforces U.S. securities law, treats the detection and prosecution of insider trading as a core part of its mandate to maintain fair and efficient markets.

What Is Insider Trading and Why Is It Illegal?

The legal framework prohibiting insider trading in the United States is grounded primarily in the Securities Exchange Act of 1934, as interpreted and expanded through decades of SEC rulemaking and court decisions. Rule 10b-5, promulgated under Section 10(b) of that Act, is the central prohibition. It makes it unlawful for any person to use any device, scheme, or artifice to defraud in connection with the purchase or sale of a security.

Two key legal theories define how insider trading liability is established:

The classical theory applies to corporate insiders who trade in their own company’s securities while in possession of material non-public information. These individuals are considered to owe a fiduciary duty to shareholders, and trading on MNPI constitutes a breach of that duty.

The misappropriation theory extends liability to outsiders, including attorneys, accountants, financial advisers, or others, who trade on material non-public information obtained in the course of a professional or confidential relationship. Even if the individual is not an insider of the company whose securities are traded, using that information for personal gain constitutes fraud against the source of the information.

Illegal insider trading undermines the principle of a level playing field. When certain investors can trade on information unavailable to others, it distorts price discovery, disadvantages ordinary investors, and compromises the integrity of public markets. For this reason, it is treated as a serious violation of federal securities law, enforceable by both the SEC through civil action and the Department of Justice through criminal prosecution.

Examples of Insider Trading

Corporate Executive Scenario

A chief financial officer at a publicly traded pharmaceutical company learns, weeks before any public announcement, that a key drug trial has failed. Knowing the news will cause the company’s stock price to fall sharply, the CFO sells a large portion of their personal shareholding before the announcement is made. When the news becomes public and the share price drops, the CFO has avoided losses that other shareholders incur. This constitutes illegal insider trading when the CFO used material non-public information to gain a financial advantage not available to the broader market.

Government Employee Scenario

A senior official at a federal regulatory agency learns during the course of their work that a major pending decision will significantly affect a publicly traded company. Before the decision is publicly announced, the official purchases shares in that company, expecting the ruling to drive the price up. Trading on non-public government information of this nature falls within the scope of insider trading prohibitions under the misappropriation theory, and can also implicate additional statutes governing the conduct of government employees.

The Tipper-Tippee Scenario

Insider trading liability is not limited to the person who possesses the original information. If a corporate insider — the “tipper” — passes material non-public information to a friend, family member, or associate — the “tippee” — and that person trades on it, both parties may face liability. The tipper must have received a personal benefit (financial or otherwise) from sharing the information, and the tippee must have known or should have known that the information was improperly disclosed.

Consequences of Insider Trading

Civil Penalties

The SEC has broad authority to pursue civil enforcement actions against individuals and entities engaged in insider trading. Under the Insider Trading Sanctions Act of 1984 and the Insider Trading and Securities Fraud Enforcement Act of 1988, civil penalties can reach up to three times the profit gained or loss avoided as a result of the unlawful trading. The SEC may also seek disgorgement of any ill-gotten gains, plus interest.

Criminal Penalties

The Department of Justice may pursue criminal charges for insider trading violations. Under current law, individuals convicted of securities fraud can face fines of up to $5 million and prison sentences of up to 20 years per violation. Corporations found liable can face fines of up to $25 million.

Can You Go to Jail for Insider Trading?

Yes. Criminal prosecution for insider trading is pursued in cases involving willful violations of securities law. High-profile convictions have resulted in significant prison sentences. Former hedge fund manager Raj Rajaratnam was sentenced to 11 years in prison following his 2011 conviction in one of the largest insider trading cases in U.S. history. Former ImClone Systems CEO Samuel Waksal was sentenced to more than seven years following his guilty plea to insider trading charges in 2002.

Reputational and Professional Consequences

Beyond legal penalties, individuals found guilty of insider trading typically face permanent or long-term bars from serving as officers or directors of public companies. In many cases, careers in finance, law, or related fields are effectively ended. Firms associated with insider trading violations may face reputational damage, client attrition, and enhanced regulatory scrutiny.

Common Misconceptions About Insider Trading

Misconception: Only corporate executives can commit insider trading. Insider trading liability extends to anyone who trades on material non-public information obtained through a breach of duty or a confidential relationship — including lawyers, consultants, financial analysts, government officials, and even friends or family members of insiders who receive tips.

Misconception: Insider trading is only illegal if you make a profit. The law prohibits trading on material non-public information regardless of whether a profit is ultimately realized. Using MNPI to avoid a loss is equally actionable. The focus is on the use of the information, not the outcome.

Misconception: Legal insider trading doesn’t exist. Corporate insiders are permitted to buy and sell shares in their own companies, provided they do so in compliance with SEC disclosure requirements. This includes filing Forms 3, 4, and 5 with the SEC to report transactions. Many insiders also use pre-arranged 10b5-1 trading plans, which allow them to schedule trades in advance under conditions that reduce the risk of MNPI-based liability.

Misconception: The SEC can only act after significant harm has occurred. The SEC actively monitors trading activity in real time using sophisticated surveillance tools that flag unusual patterns such as large options purchases ahead of a major corporate announcement. The agency can and does initiate investigations based on anomalous trading data, often before any public complaint is filed.

Misconception: Information from a public source is always safe to trade on. The relevant question is not only where information came from, but whether it was obtained through a breach of a duty of confidence. In some circumstances, trading on information derived from a confidential relationship can still give rise to liability depending on the timing and circumstances.
