Sometimes those that have lots of fans don't bother with comments. That is fine. But requesting comments and feedback and then not providing any responses I find doesn't show much respect for people.
Why Does Apple Care About Its Share Price?
Put simply, executives should spend more time on product development and customers and less time worrying about something (their stock price) that is more outside their control.As a stockholder I agree with you. Apple has continued to have a great cash flow. Mainly they should focus on that. Apple has diluted stockholder equity by over 10% over the last 7 years with massive stock grants to executives. The $50 billion buyback is unlikely to even return outstanding stock levels to the level of 7 years ago.
Along with the excessive nature of their cash balance (I am all for keeping some money for a raining day and keeping money to invest in research and new market but they have $100 billion more than they need for that) and stockholder dilution they have practiced putting some cash to use reducing the stockholder dilution makes sense to me.
