I wont at least till end of this year. It will likely not reach 600 but 500s is a good possibility and some dividend will cut your losses. My average price was in 500. I have lowered my average to 430s by buying when it goes to 390s. ( many people dont recommend that) but I am very close to green, hopefully next week. Any profit I make will be a long term gain taxed at lower rate.
My feeling many analyst including Cramer have been wrong so many times in past on upgrading AAPL that emotion is coming into play. I think this time AAPL will go up.
Buy in 390s only if it has retested 385 on ascent, not falling if at all that happens. But if things dont improve by fall/ winter better to get out. My 2 cents
