Insider Trading.

Insider Trading is the trading of a company's (A Listed Company in this case) stock or other securities by individuals with potential access to non-public information about the company. Simply put, Insider Trading means buying or selling stocks, bonds or other securities based on significant information that's not available to the general public. Besides creating an uneven playing field that disadvantages regular investors, Insider Trading by corporate officials also violates their responsibility to operate in the best interests of shareholders.
