But "buying back stock" only temporarily creates value for the shareholder. If they don't immediately sell the stock, the price will return to what it was before they buyback, because no underling value in the company has increased (especially when dividends are never payed out, like most high tech companies that are always in the "growing" phase : looking at you FB, Goog etc).
