If you are long, you will be fine. I think this will move up to your target price range with in a few months. I'm going long here for years likely.
I know a few whiting employees. I feel pretty good about whiting surviving this down turn and thriving in the long run.
I am not a trader. I always invest in stocks that will have long run potential for big returns. I feel confident enough in WLL to go long with this one.
