There is a variety of possible reasons, and I couldnt come up with any negative reasons.

Simplest and most astute one would be fund taking positions in both companies based

on possible upside for year 2013... and the pricing based on latest Columbian takeovers.

I would ascribe a better flowing BOE value on PTA than some of what has already transpired.

I ve been talking about upside and to be forward looking for a while... Its likely someone has

come to a similar conclusion, and they were able to trigger their trade today. People dont buy

size on a whim, and Im sure it was well researched. End of my most plausible theory. Theres

others, but not as likely... steady as she goes... patience..
