One of the real reasons of last days run is probably that it appears the ICE is now really taking over Light Sweet Crude (futures). The process seems exponential when you look at the last 5 days. Today volume in WTI was > than volume in Brent. This is ridiculous. If the NYMEX does not act now (meaning, NOW, next week can be late already), there is a real danger they gonna lose it. And getting it back will be hard.
Stock is rapidly approaching the 52 week high again, will be interesting to watch and see what happens once it hits that area of resistance.
