What Is Insider Trading?
Insider trading is buying or selling securities while using material nonpublic information, or otherwise trading in a way that violates securities laws. In plain English, it usually refers to trading based on important information that has not yet been shared with the public.
The term is sometimes used loosely, but it has a more specific meaning in securities law. A person can be a company insider without committing insider trading, and a trade by an insider can be legal when it follows the rules.
Key Takeaways
- Insider trading generally involves trading securities while using material nonpublic information.
- A corporate insider is not the same thing as insider trading.
- Legal insider transactions may still have to be reported publicly, often through Form 4.
- Rule 10b5-1 trading plans can create a prearranged framework for certain insider trades.
- The central issue is whether the trade used information that was important and not yet public, or otherwise violated securities laws.
What Material Nonpublic Information Means
Material nonpublic information is information that has not been made public and that a reasonable investor would likely consider important in making an investment decision. Examples might include unreleased earnings results, a pending merger, a major contract, a regulatory decision, a product failure, or another meaningful company development.
If the information is both important and not yet public, trading on it can create serious legal risk.
How Insider Trading Differs From Legal Insider Transactions
Insider trading focuses on improper use of information or other unlawful trading conduct. Legal insider transactions are different. Officers, directors, and certain large shareholders may buy or sell company stock when they comply with applicable rules, avoid trading on material nonpublic information, and make any required disclosures.
For example, an executive may sell shares for diversification, taxes, estate planning, or compensation reasons. That transaction may still be reported publicly, but the reporting itself does not mean insider trading occurred.
Why Rule 10b5-1 Plans Matter
A Rule 10b5-1 trading plan can allow insiders to set up future trades under preset conditions. These plans are designed to help insiders trade without making a fresh decision while they may possess sensitive information later.
A trading plan does not make every transaction meaningless. It simply changes the context. The plan, timing, size of the trade, ownership remaining, and company fundamentals can all matter when someone is trying to understand insider activity.
The Bottom Line
Insider trading is the improper use of material nonpublic information, or other unlawful conduct, in securities trading. Legal insider transactions can still happen and may be reported publicly. The important distinction is whether the trade followed the rules and whether material nonpublic information was involved.
