Tricky Motherfrackers

David Einhorn came out swinging today at the Ira Sohn Conference, sticking it to fracking plays and labeling them as "motherfrackers." 

In particular, his bear thesis and "motherfracker" commentary pointed towards Pioneer Natural Resources. (PXD). 

First and foremost, PXD reports earnings tomorrow, which could certainly trump any current theses or technicals. But a larger point here could very well be that after a strong multi-year advance off the 2009 bear market lows, seen on the weekly chart, below, Pioneer could have already topped out well in front of the Einhorn comments. 

Barring a rally back over $182 anytime soon, you can see the potential topping pattern playing out, with a move under $150 likely leading to a fresh leg down.
