Four days ago, with the stock closing at $161.64 (see previous blog) we opined that this thing should trade to about $125 to complete a symmetric a-b-c pattern. It did those extra $36 in 3 days and bottomed (so far at least) at $125.25. I call that a whole-hearted recommendation for the efficacy of EW, not that I need convincing. Now , as always, time is the Achilles heel.
