All is a matter of momentum because SGY's fundamentals are stellar. As another guy posted, look the EV of BCEI (Bonanza) and its whopping ratios. SGY does not have momentum currently but it can change any time burning the shorters. SGY is the best value in the oil-weighted companies of the North America.
MTRX (Matrix) has stong momentum lately but it is very expensive. Check the fundamentals to confirm it.
ROYL (Royale Energy) has also some very good drilling results in Alaska.
