Using an expert network becomes insider trading when the industry expert shares material non-public information about a public company and the investor trades on it knowing, or having reason to know, that the expert broke a confidentiality duty for some personal benefit. Everything else about expert networks insider trading law flows from that single sentence: the definition of “material non-public,” the duty the expert owes, the knowledge the investor must have, and the theory of fraud prosecutors use to turn a paid phone call into a federal crime carrying up to 25 years in prison.
The consultation model itself is legal. Hedge funds, mutual funds, and other institutional investors pay former executives, scientists, engineers, and consultants for their industry expertise, and the network handles the matchmaking and the fee. The problem is not the arrangement. The problem is what gets said on the call.
What Counts as Material Non-Public Information
Every enforcement case in this area turns on whether the information exchanged was material and non-public. Both words do independent work.
Information is material when a reasonable investor would consider it important to a buy, sell, or hold decision. The Supreme Court’s standard asks whether there is a “substantial likelihood” that the fact “would have been viewed by the reasonable investor as having significantly altered the ‘total mix’ of information made available.”1U.S. Securities and Exchange Commission. Assessing Materiality: Focusing on the Reasonable Investor When Evaluating Errors Unreleased earnings, a pending merger, a regulatory decision on a key product, a major contract about to be signed or lost — these are the standard examples.
Information is non-public until the company disseminates it broadly to the market through a press release, an SEC filing, or a public earnings call. A private meeting with a handful of analysts does not make information public. Widely circulated rumors do not make it public either, as long as the company has never confirmed the underlying fact through channels available to all investors.
A former pharmaceutical executive discussing general trends in drug development is fine. That same executive revealing unpublished clinical trial results is a federal crime. The distinction can be razor-thin in a real conversation, which is why the rules on who knew what, and how, matter so much.
How the Tipper-Tippee Rules Work
Expert network cases almost always follow a tipping pattern. The expert is the tipper. The investor is the tippee. The two sides face different legal tests.
The Expert’s Side
The tipper must breach a duty of trust and confidence and receive a personal benefit for doing so. In an expert network context, the duty usually runs to the expert’s current or former employer, and it is often reinforced by a written confidentiality agreement with the network, the employer, or both.
The personal benefit element is where expert network cases become easier for prosecutors than ordinary tipping cases. The Supreme Court in Dirks v. SEC held that a personal benefit can include an enhanced reputation, an expectation of receiving valuable information in return, or the intention to make a gift of the information.2Justia Law. Salman v United States, 580 US (2016) In an expert network setting, the consultation fee is itself evidence of a personal benefit. The expert is being paid.
The Investor’s Side
The tippee’s liability depends on the tipper’s breach. The investor must know, or have reason to know, that the expert disclosed the information in violation of a duty and for a personal benefit. The Second Circuit stated the point directly in United States v. Newman: the government must prove “beyond a reasonable doubt that the tippee knew that an insider disclosed confidential information and that he did so in exchange for a personal benefit.”3Justia Law. United States v Newman, No 13-1837 (2d Cir 2014)
That knowledge requirement protects an investor who genuinely does not realize the information is confidential. It does not protect willful blindness. An analyst who pays for a consultation, receives obviously non-public details about upcoming earnings, and then trades on them cannot credibly claim not to have understood what happened.
The Two Fraud Theories Behind the Charge
No federal statute explicitly defines insider trading. Prosecutors charge it under the general anti-fraud provision of the Securities Exchange Act. Section 10(b) prohibits the use of “any manipulative or deceptive device” in connection with a securities transaction,4Office of the Law Revision Counsel. 15 USC 78j and the SEC’s Rule 10b-5 forbids fraud and deceit in securities transactions.5eCFR. 17 CFR 240.10b-5 – Employment of Manipulative and Deceptive Devices Courts have built two theories on those provisions.
The classical theory covers corporate insiders who trade their own company’s stock while holding confidential information; the fraud is against the shareholders to whom the insider owes loyalty.6Congressional Research Service. Legal Sidebar – SECs First Shadow Trading Case Slated for Trial
The misappropriation theory is the one that drives expert network cases. It targets outsiders who misuse confidential information belonging to someone else. When a former researcher shares confidential clinical data with a hedge fund analyst, the researcher is misappropriating information that belongs to the employer, and the deception is the researcher’s pretense of keeping the confidence while secretly breaking it.6Congressional Research Service. Legal Sidebar – SECs First Shadow Trading Case Slated for Trial
Rule 10b5-2 spells out when a duty of trust or confidence exists for misappropriation purposes. It arises whenever a person agrees to keep information confidential, whenever two people have a history or pattern of sharing confidences such that the recipient should know the information is expected to stay private, or whenever a person receives the information from a spouse, parent, child, or sibling.7eCFR. 17 CFR 240.10b5-2 – Duties of Trust or Confidence in Misappropriation Insider Trading Cases Experts routinely sign confidentiality agreements with their employers and with the networks themselves. That signature is what plants the duty whose breach becomes actionable fraud.
What Legitimate Expert Network Use Looks Like
The mosaic theory is the analytical practice that keeps expert networks legal. Analysts can piece together individually non-material bits of public information and non-material non-public information to reach a material conclusion. The SEC stated in its Regulation FD release that it does “not intend, by Regulation FD, to discourage this sort of activity” and that its focus is “on whether the issuer discloses material nonpublic information, not on whether an analyst, through some combination of persistence, knowledge, and insight, regards as material information whose significance is not apparent to the reasonable investor.”8U.S. Securities and Exchange Commission. Final Rule: Selective Disclosure and Insider Trading
The theory has a hard limit. No single piece in the mosaic can itself be material and non-public. One item of true MNPI contaminates the entire analysis, no matter how much public information surrounds it.
Regulation Fair Disclosure sits alongside these rules. Reg FD requires public companies to disclose material information to all investors simultaneously rather than sharing it selectively with favored analysts, and unintentional selective disclosures must be corrected promptly.9eCFR. 17 CFR 243.100 – General Rule Regarding Selective Disclosure Expert consultations do not automatically violate Reg FD because the rule contains an exception for anyone who agrees to keep the information confidential. That agreement, though, is the same agreement that creates the duty of trust under Rule 10b5-2. The confidentiality that saves the company from a Reg FD violation is what exposes the expert to an insider trading charge if they then breach it.
Criminal Penalties
Insider trading can be charged under two federal statutes, often stacked together.
Under the Securities Exchange Act, a willful violation carries up to 20 years in prison and a fine of up to $5 million per violation for individuals. Corporate entities face fines of up to $25 million.10Office of the Law Revision Counsel. 15 US Code 78ff – Penalties Under the broader federal securities fraud statute, 18 U.S.C. § 1348, the maximum climbs to 25 years.11Office of the Law Revision Counsel. 18 US Code 1348 – Securities and Commodities Fraud
Actual sentences in expert network cases have run into the years. Raj Rajaratnam of Galleon Management received 11 years in prison, $53.8 million in forfeiture, and a $10 million fine after his conviction on 14 counts of conspiracy and securities fraud in May 2011.12U.S. Securities and Exchange Commission. SEC Enforcement Actions: Insider Trading Cases Mathew Martoma, the SAC Capital-affiliated portfolio manager who used expert network consultations to obtain confidential Alzheimer’s drug trial data, was sentenced to nine years.13U.S. Department of Justice. SAC Capital Portfolio Manager Mathew Martoma Sentenced in Manhattan Federal Court to Nine Years in Prison
Civil Penalties, Disgorgement, and Bars
The SEC pursues civil enforcement in parallel with, or independently of, criminal prosecution. Civil remedies target the money and add punitive penalties on top.
Courts can order violators to disgorge profits gained or losses avoided through illegal trades. After the Supreme Court’s decision in Liu v. SEC (2020), disgorgement is limited to the wrongdoer’s net profits after deducting legitimate expenses, and it generally must be directed to harmed investors rather than the government’s general fund.14Supreme Court of the United States. Liu v SEC, No 18-1501 (2020)
On top of disgorgement, the SEC can seek a civil penalty of up to three times the profit gained or loss avoided.15Office of the Law Revision Counsel. 15 US Code 78u-1 – Civil Penalties for Insider Trading Combined, the total financial exposure can reach four times the illegal profit: once through disgorgement and up to three times again as a penalty. Civil settlements in this space have been enormous. CR Intrinsic Investors, an affiliate of SAC Capital, agreed to pay more than $600 million in the Martoma matter, at the time the largest insider trading settlement in history, and the SEC obtained a $92.8 million civil penalty against Rajaratnam.12U.S. Securities and Exchange Commission. SEC Enforcement Actions: Insider Trading Cases
Courts can also impose permanent injunctions against future securities law violations, and they may prohibit a person from serving as an officer or director of any public company if the conduct “demonstrates unfitness to serve.”16Office of the Law Revision Counsel. 15 USC 78u – Investigations and Actions
Firm-Level Exposure: Controlling Person Liability
The penalties are not limited to the individual on the call. Investment firms and supervisors face separate liability as controlling persons. A manager who knew or recklessly disregarded the fact that an employee was likely to trade on inside information, and failed to take steps to prevent it, faces a civil penalty of the greater of $1 million or three times the illicit profits. Firms can also be held liable for knowingly or recklessly failing to establish and enforce compliance policies that could have prevented the violation.17Office of the Law Revision Counsel. 15 USC 78u-1 – Civil Penalties for Insider Trading The provision gives firms a direct financial incentive to build real compliance infrastructure around their expert network programs.
What a Conviction Does to a Securities Career
An insider trading conviction effectively ends a career in the securities industry. Under FINRA’s rules, a felony conviction or any misdemeanor conviction involving securities triggers “statutory disqualification.” A disqualified person cannot associate with any FINRA member firm in any capacity unless they go through a formal eligibility proceeding, and that process is neither quick nor guaranteed to succeed.18FINRA. General Information on Statutory Disqualification and FINRAs Eligibility Proceedings
The disqualification lasts ten years from the date of conviction for criminal offenses, and SEC-imposed bars can be permanent. An SEC finding of a willful violation triggers disqualification on its own, whether or not the Department of Justice brings criminal charges, and even a civil injunction issued by a federal court can trigger the bar. Firms must report disqualifying events within 10 days, so quietly moving to a new employer is not an option.18FINRA. General Information on Statutory Disqualification and FINRAs Eligibility Proceedings
Compliance Practices That Reduce the Risk
Firms that use expert networks extensively have built compliance programs designed to prevent MNPI from entering the investment process. The controls do not eliminate risk, but they create a defensible record and reduce the likelihood of a problem on the front end.
- Expert screening and conflict checks that verify the expert’s identity, map their employment history against restricted lists, and confirm they are not currently bound by confidentiality obligations that would prohibit the discussion.
- Pre-call attestations in which experts certify before each consultation that they will not share MNPI or breach any confidentiality agreement.
- Consultation monitoring and recording, with compliance teams reviewing calls in real time or afterward and automated systems scanning transcripts for keywords associated with confidential information.
- Complete record-keeping, logging the expert’s name, the topic, the date, the duration, and often a full transcript, with records retained for at least three years.
- Ongoing expert training on identifying and avoiding MNPI, with periodic reaffirmation of the network’s terms.
- Escalation procedures giving employees and experts clear instructions and incentives to flag conversations that approach sensitive territory rather than press forward.
For the expert on the other end of the line, the working test is simple even when the moment is not: share only what you could say on a public stage without consequences. If it would not go into a conference presentation or a published interview, it should not go into a paid consultation.
