Number 1, Mr. Icahn just wants to pump up the stock price so he can sell and profit. That's his MO. Get lost, Carl.
Number 2, Mr. Icahn yes is a large shareholder. However, in order for him to actually have any power, he would have to be able to convince a large group of other shareholders representing a much larger percentage of the stock to go along with what he wants and force a vote on the matter. This isn't going to happen any time soon. So again, get lost Carl.
And finally Number 3, Apple uses that huge cash hoard to put its weight behind things and get what they want. Like pre-purchasing stocks of silicon, raw materials, buying Beats, etc. Other companies know Apple can just buy whatever it wants or go someplace else, and that gives Apple a lot of power in the marketplace. So no I'm not for distributing most of the cash to people like Icahn. So again 2x, get lost Carl.
Point three I disagree with. I don't think having $166B gives Apple anymore weight in the marketplace than if it had $50B. It can do all those things you mention with a fraction of the $50B. Also banks would open up working capital lines at near zero interest for Apple in heartbeat.
And iPhone 6 is a huge success. So huge amounts of more cash is coming. Tidal waves of it.
