BTU = $20 by the end of the week? IMO you have your head stuck someplace where the sun doesn't shine. Why? prices are not going to change much anytime soon. Volumes are not going to increase anytime soon. The global economy is growing slowly, pretty much at stall speed. BTU will likely be higher at some point in the future, but it is going to be a slow slug for months yet.
U just dont't know. But, it can happen fast. We know this for now. 20 is not a reality this week. It can be in a few weeks though. I hoping after labor day coal starts getting interest from bigger buyers for winter. We will see.
