re: Apple up over 10% and $47 since last week....what do we see first $500 or $400

Exactly, you get the 52-week high and 52-week low. In between those you map the Fibonacci percentages, 0% = 52 week low, 23.6%, 38.2%, 50%, 61.8%, 76.4%, and finally 100% equals your 52-week high. Look from the high in mid-September to the low recently mid-April. Even before we hit the 52-week low prices were using these lines as support/resistance levels.

Let me see if I can upload the Bloomberg screenshot to photobucket to show you what I'm talking about.
