"the company itself buy at least 500 Million shares back"
With what? You do know where they get the their money for salaries, plane fares, rent and light bills from, right?
See a million bucks laying around which the company can spend on whatever they want?
Would it make sense for YAGI to buy back 500,000,000 shares while selling tens of millions shares on the open market every chance they get at the same time?
