Apple rally is intense. Its about 100 points greater than I expected, thus far. Funny thing, after they reported their July 2011 quarter, I was expecting this very thing! After a blowout quarter, Apple pulled back, then got swept with the rest of the market as Europe shocked the market. Obviously I was humbled in July or 6 months too soon :)
The current rally started about a week after Apple stated their Jan quarter. Apple went from 450 to 525 (a 16% move) before a 5-6% pullback. Then it went from 490 to 548 (a 11-12% move) before a 6% pullback. Now, the current move started at 516 and its saw a 15% move (with 594 being the high).
Should a 6% pullback be expected?
I hope so.
IMO, the only real trading concern, at this point, is the headline risk of Apple being re-adjusted in the Qs because of its size. Near, or below 520, Apple was 17% of the Qs. Since then, Apple has risen 14% and the Qs have risen around 4.5%. Apple has out grown the Qs by 10%. (The index threshold is around 20%, I think.)
