Just because at this time, Apple is the best company in the world, doesn't mean its stock can't temporarily be decimated.
The advance/decline line has not reflected the Dow (which I'm sure has 30 companies whose stocks are are totally manipulated), meaning that this is a completely phony market.
Almost no "high flyers" like AAPL escape the wrath of a down market. The S&P has bounced off the 1263 Moving average twice, once on June 16, and again on June 22nd. There are only 5 points left on the downside of the S&P, before it breaks its 200 Day Moving Average.
It would be smart to look at the S&P this week, in conjunction with the stock.
If the S&P holds, I would be a buyer. If the S&P breaks, I would stand on the side lines.
If I already owned the stock and bought it at a much lower price, I would do nothing.
I remember Xerox (when it had the only copier on the market) go from 325 down to 125 in 6 months. There were some planted rumors that another company (at the time un-named) was coming out with a better copier. It never happened
It then turned around within the next year, and went above 400 where it split 5:1.
I'm not saying the same thing will happen to AAPL, but just showing that a stock can go down because of market conditions, or for no reason at all.
