Insider Trading and Insider Buying: The Basics

Insider trading and insider buying both involve corporate insiders and company stock, but they differ significantly in legality and ethical implications. Insider buying is legal when it complies with SEC rules, requiring timely disclosure of transactions. Illegal insider trading, however, involves using confidential information to make trading decisions, which is strictly prohibited.
