Oil's wild ride is showing no signs of slowing down.
After starting the year in the red, crude has rebounded 51% in the past 6-months.
But the Street is mixed on whether oil can sustain its rapid rise.
Today Goldman Sachs released a note arguing that the rebound has not been driven by strength in fundamentals. The firm believes the ascent is simply due to headlines about a potential OPEC freeze.
On the other hand, Jefferies is seeing buying opportunities in the energy sector -- specifically in the refiners. Today the firm initiated coverage on Marathon Petroleum, Tesoro, and Valero Energy -- giving all of them "buy" ratings.
The "Halftime Report" experts debated the call, including whether or not crude's comeback will be short-lived.
