If you work for a company that's publicly traded, you could be subject to blackout periods during which you're not allowed trade the company's stock. You might have access to nonpublic information, with a potential for illegal insider trading. A blackout period is generally part of a company's internal policy. It's meant to prevent corporate insiders from unfairly benefiting -- intentionally or inadvertently -- from trades in the stock market. A company may impose a blackout period only on key executives, or it may apply it to a broader group of employees.
