I would think the $13 price already factors this in. The dividend seems to be guaranteed to be at least $2.40 for the next few years (10K). So that is about 18% return. Lots of reason to have had the stock beaten down, but it probably does not deserve more. If it does . I would pick up some more shares as any drop is just more messing with the stock. Price of Nat gas has been better, oil ok. Fundamentals of pricing (commodity) are improving.
Don't know about a few years. I would say SD would try to finish the drilling programs as soon as possible now to eliminate the subordination thresholds. SDT is pretty close to completing the drilling program which means that in a little over a year the subordination support will fall away.
Next few years? That's assuming quite a bit considering each quarter is getting cut and looks like this is the trend going foreword. Each cut only pushes the PPS lower, thus making it hard to hold on to that dividend. Just look at a chart on all of the oil trusts. Buy & Hold is not working out.
