* Open Market Insider Buys refer to transactions where insiders purchase common or preferred shares of their own company in the open market in the same way an investor would do. These tend to be far more indicative of insiders' confidence in the company than other forms of acquiring shares such as stock grants, gifts, or exercising of stock options.
