Blue skies for Exxon Mobil (XOM/XOMX)?Exxon Mobil CorporationBATS:XOMAM_CapExxon Mobil has been trading sideways for 3 years now. Closed the week above 120. XOMX is 2x leverage long for XOM. It's interesting to see that XOM has broken out of the range with WTI still languishing around (blue line on the chart).Could XOM be leading WTI here? Only time will tell but the comparative strength is noticeable. Personally, I would not be long XOM or XOMX as it is a slow mover. If it does have a legitimate breakout, blasts past 130, it's green light for other stocks in the oil sector. Yet to identify which would be the momentum leader but in the coming weeks it would become apparent.
