If a company's directors are buying more shares of their company, should I take it as a signal that they value the company well, and I should follow them and buy shares in that company? The only reason I can see as to why a company's directors would buys shares is because they think they will go up in price. So would it be a safe strategy to follow their buying?
Likewise, if I see a company's directors selling shares of their company, should I also sell my shares? I am curious to know why a company's directors would SELL their shares in their own company? Is it due to slower earnings growths etc.?
