Insider trading

Monitoring trades made by the management members or major shareholders of companies may help create a sharper picture of what is happening inside the companies. Base your decisions on buys or sells of the people involved and do the right thing at the right time.

Who is insider?

Every director or senior officer, as well as any other entity or individual owning more than 10% of the company’s shares on the stock market, is called an insider. Such people or entities are allowed to buy/sell the company's shares under strictly controlled conditions. Key premise here is that none of them can make trades based on non-public information about the company.
