Why CEOs Are Buying Stocks Of Their Own Companies?

1. As legendary investor Peter Lynch said: "Insiders might sell their shares for any number of reasons, but they buy them for only one: they think the price will rise."
2. TOP EXECUTIVES like CEOs and CFOs are savvy buyers of their companies' shares. One long-term study showed that they beat the market on average by six percentage points a year.
3. Another study found that the aggregated activities of insiders can serve as a good indicator to locate market bottoms. Insiders as a whole are smart investors of their own companies.
