Insider Trading Explainer
Illegal insider trading generally involves buying or selling securities while aware of material nonpublic information in breach of a duty of trust or confidence, or tipping that information to someone who trades. The law can reach executives, employees, advisers, contractors, family members, and other tippees depending on the facts.
Information is material when a reasonable investor would likely view it as important, and nonpublic until it has been broadly disseminated with time for the market to absorb it. Earnings, deals, financing, product developments, investigations, or leadership changes can qualify, but context controls.
Not every trade by an insider is illegal. Directors and officers can trade when not using prohibited information and must follow reporting rules and company policies. A properly established Rule 10b5-1 plan can provide an affirmative defense when adopted before the trader becomes aware of material nonpublic information and other conditions are met.
Blackout windows and preclearance reduce risk but do not replace the legal analysis. Tipping can create liability even when the source does not trade. Companies should control access, train personnel, document decisions, and coordinate public disclosure rather than treating rumor or partial release as a safe harbor.
The information must be important to investors and not yet broadly available.
Context determines both elements.
Liability may reach the source, trader, and downstream tippee.
A direct personal trade is not the only pathway.
Reporting, company policy, and valid trading plans support compliant transactions.
Possession of inside information can still block a planned trade.
