-because Carl Icahn says Apple is underpriced by 2x? -because AppleWatch is launching soon? -because of iCar rumors?
Firstly, Carl Icahn as an activist investor himself and having invested into Apple shares himself makes his credibility zero. Can you really take this guy's words for real? When is he going to dump on you?
Second, will Apple Watch really take off like what many claims it will be?
Third, people are buying into the rumor of Apple developing a car and that might bring in a potential 100b + revenue? what? Sure if you're speculating on Tesla, but Apple Car isn't even out to date. Buy the rumor, sell the news. (See: tradingview.com/v/prkfU7Tq/ )
To sum things up, there's simply so much more to lose than to gain from buying here. The market will always be there, sometimes you're better off not trading and wait for an opportunity. Patience is the word.
Sure if you've already bought Apple at a low price, its still worth holding it over long term.
