If Apple doesn't want this price to fall any further, IT WON't!!! Part of the reason for keeping their cash is to keep the stock at a level that they feel it needs to remain at. I suspect they are very close to the level they don't want it to fall below. They don't have to do anything more than make a token apology for AAPL's present stock price; if Einhorn sells all of his shares, so be it - AAPL will buy them right back, and then some. Actually, I believe he realizes it - that's why he's not selling! I believe there's very little chance of AAPL falling any lower than this level!
