Six Possible Defenses for Insider Trading Charges
An insider trading charge rarely arrives alone. It usually comes with an SEC inquiry, a parallel criminal investigation, a freeze on the account that made the trades, and a story in the financial press before you have said a word. A conviction under the federal securities laws can mean prison, a fine of up to $5 million, disgorgement of every dollar of profit, and a permanent bar from the industry you built a career in.
But the government has to prove a specific set of things, and each one is a place where a case can fail. Insider trading is not a crime of suspicious timing. It is a crime of trading on material, nonpublic information in breach of a duty, and doing so willfully. Take away any one of those elements and there is no case.
Want the basics on what counts as insider trading and what happens when the SEC calls? Start with our Insider Trading Attorney page. Below, I'll walk through the defenses I rely on most, in plain terms, with examples.
1. The information wasn't material, or wasn't nonpublic
The statute, Section 10(b) of the Securities Exchange Act, and SEC Rule 10b-5 reach only material, nonpublic information. Under Basic Inc. v. Levinson, information is material if a reasonable investor would consider it important in deciding whether to buy or sell. That is a real threshold. A rumor, a hunch about the industry, a colleague's mood in the hallway, or a fact that had already been reported in a trade publication does not clear it.
Say a mid-level engineer hears that a product launch might slip a few weeks, and she sells some stock. The government calls it inside information. But if the delay was too minor to move the price, or if an analyst had already written about it, the information was not material, or was not nonpublic, and the case falls apart at the first element. Much of the early work in these cases is reconstructing what the market already knew on the day of the trade.
2. You owed no duty to anyone
Insider trading is a breach-of-duty crime, not a possession crime. Under the classical theory, the defendant is a corporate insider who owes a duty to the company's shareholders. Under the misappropriation theory the Supreme Court adopted in United States v. O'Hagan, the defendant is an outsider who owes a duty of trust or confidence to the source of the information, such as a lawyer, a consultant, or a spouse who promised to keep a secret. Rule 10b5-2 spells out when that kind of duty exists.
If you owed neither, you are not an insider trader, however good your information was. The person who overhears a conversation on a train, or who works out a merger from public filings, parking-lot activity, and a canceled conference appearance, has breached no duty. Prosecutors sometimes stretch the idea of a confidential relationship past what the rule says, and pushing it back to the text is a defense in itself.
3. You were a tippee who didn't know the tipper was breaching a duty for a personal benefit
Most insider trading cases are tippee cases: someone else had the information and you traded on it. Since Dirks v. SEC, a tippee is liable only if the tipper breached a duty in exchange for a personal benefit and the tippee knew it. Salman v. United States confirmed that a gift of information to a trading relative or friend counts as a benefit, but the tippee still has to know about the breach.
That knowledge requirement matters most at the end of a chain. If a friend of a friend of an executive told you something at a dinner, you may have had no idea where it came from, whether it was confidential, or what the original source got in return. Remote tippees who could not have known about the breach have won dismissals and acquittals on exactly this ground.
4. You didn't trade on the information
The government has to connect the information to the trade. If you sold on a schedule you set months earlier, under a written Rule 10b5-1 trading plan or a standing instruction to your broker, the timing is explained by the plan, not by anything you learned. The same is true of trades that fit a long pattern: the executive who has sold 5,000 shares every quarter for six years is hard to paint as an opportunist for selling 5,000 shares this quarter.
This defense is stronger in San Francisco than in most of the country. In United States v. Smith, the Ninth Circuit held that in a criminal case the government must prove the defendant actually used the inside information, not merely that he possessed it when he traded. Independent reasons for the trade, a tax bill, a house purchase, a portfolio rebalance ordered by an adviser, are evidence that goes to the heart of the charge.
5. You didn't act willfully
A criminal insider trading conviction requires a willful violation under Section 32(a) of the Exchange Act. That means the government must prove you knew your conduct was wrongful, not just that you traded and, in hindsight, should not have. A good-faith belief that the information was already public, a trade that was pre-cleared by the company's compliance department, or a trade made on the advice of counsel each go directly to willfulness. So does a blackout-period lapse that was a calendar mistake rather than a scheme.
Willfulness is also where the difference between the SEC and the Justice Department shows up. The SEC can bring a civil case on a lower standard; a criminal case has to prove the state of mind beyond a reasonable doubt. Part of the early strategy in every one of these matters is keeping a civil problem from becoming a criminal one.
6. The government's case is circumstantial, and the pieces don't fit
Insider trading cases are built from trading records, phone logs, and relationships. Very few come with a recording of someone saying "buy now, the deal closes Friday." The government's story is usually: you knew this person, you spoke to them on this date, you traded the next day, and the stock moved. Each link in that chain can be tested. The call may have been about something else. The trade may match a dozen others. The stock may have moved for reasons that were public by then.
Building the alternative explanation, with the trading history, the analyst reports, the news timeline, and the witnesses who can say what a conversation was actually about, is where these cases are won or lost. The mosaic theory, under which an investor may combine many pieces of public and immaterial information into a valuable conclusion, is a legitimate defense that the SEC itself recognizes.
Every case is different
Which of these defenses applies depends on facts that only a careful review of the records will show, and on which statute you are charged under. Prosecutors increasingly bring insider trading cases under 18 U.S.C. § 1348, the securities fraud statute, where some courts have treated the personal-benefit requirement differently than under Rule 10b-5. Which theory the government picks changes the defense, and it is one of the first things I look at.
Talk to a lawyer early
If an SEC attorney or an FBI agent has contacted you about your trades, do not try to explain them on your own. Answering is voluntary, and an innocent explanation given without the records in front of you can be turned into a false-statement charge later. Politely decline, and call a lawyer who handles federal securities cases before you say anything else. The earlier the defense starts, the more of these options are still open.
