Insider Trading: What It Is and Why It’s Illegal

Insider trading happens when someone buys or sells a stock using confidential company information that the public doesn’t have. This gives them an unfair edge and breaks the law.
Legal vs. Illegal Insider Trading
Not all insider trading is illegal. Here’s the difference:
- Legal Insider Trading: Employees, executives, or board members can buy or sell their company’s stock, but they must report these trades to the Securities and Exchange Commission (SEC).
- Illegal Insider Trading: When someone trades based on private information that hasn’t been released to the public, it’s illegal.
How Happens
Here’s a simple look at how illegal insider trading works:
- Access to Confidential Info: An employee, executive, or adviser learns important company news.
- Trading Before the News Breaks: They buy or sell stock before the public knows.
- Profit or Loss Avoidance: Once the news becomes public, the stock price changes. The insider makes a profit or avoids a loss.
- Investigation: Regulatory agencies, like the SEC, track suspicious trades and launch investigations.
Real-World Examples
Famous insider trading cases show how serious the consequences can be:
- Martha Stewart: She sold shares of ImClone Systems after getting a tip. She later went to prison for lying to investigators.
- Raj Rajaratnam: This hedge fund manager ran one of the biggest insider trading schemes in history and was sentenced to prison.
- Enron Executives: Leaders at Enron sold their stock before the company’s financial troubles were made public.
Why Is Illegal
Insider trading is against the law because it’s unfair and harmful to the market.
- Hurts Everyday Investors: Insiders win while others lose.
- Distorts the Market: Stock prices can be manipulated.
- Kills Trust: When people think the market is rigged, they’re less likely to invest.
The law is there to make sure everyone plays by the same rules. The SEC and other agencies monitor markets to protect investors and keep things fair.

Keeping Markets Fair for Everyone
Insider trading is more than just cheating—it affects everyone. It gives a few people an edge and hurts everyday investors. It also makes people think twice about putting their money in the market. That’s why stopping it matters.
If you suspect insider trading, report it. The SEC even rewards whistleblowers in some cases.
