The catalyst is the bullish article in IBD last Friday. It was in their new America section.
I tried to send the link earlier but Yahoo filters would not let go through.
Seems they have some very good acreage in the Wattenberg Field drilling area; about 72 percent oil barring pay.
It appears like they will almost double their revenue this year.
As far as I can tell it's just more piling in from their 2013 guidance they gave the other day. Still way undervalued. 20 times this years earnings target would put it at $46/share. Today's volume isn't that high though, so it could pull back a little though. I am holding on to my shares tightly though.
