As oil turned positive for 2015 Wednesday, Jon Najarian looked to capitalize on the crude comeback through the purchase of a company that's a direct play on the development of oil fields.

Najarian, who is up almost 5 percent on the year in the Halftime Report Model Portfolio contest, is the second trader in the competition in two days to buy an energy stock in order to benefit from the oil surge.

WTI crude was up more than 3 percent midday Wednesday to a new high for 2015 after a report showed oil inventories grew by less than expected. The commodity is now up almost 30 percent from a 6-year low touched less than a month ago.
