Apple (AAPL) stock hit $575 last week but has since pulled back about $15. It has been quite a 2nd half of 2013 for Apple (AAPL). Everyone was selling the stock below $400 in July but now everyone is buying shares in a frenzy. News that would have crushed the share price back in June is not hurting the stock at all.
Carl Icahn continues to promote Apple (AAPL) and as long as he remains a shareholder, I don't see the stock dropping much from here. Apple (AAPL) will have support at $545 and resistance at $575.
