Quote from Mark Mcrae:
Apple has fallen so drastically because the 4Q earnings report fell within (but on the low end of) extremely lofty projections, rather than exceeding them, and because the 1Q projections were lower than expected. But if you look at the raw numbers, you would still be hard-pressed to find a stronger buy, even if this stock were at $550.
I agree with those who say "wait to see - it didn't hold at $450 and could drop even lower" - but I also say you should get in on it. There are no numbers to support such a steep decline; the only thing to support such a steep decline is fear and following the crowd!
