Occidental Petroleum and Diamondback Energy may be poised to rally after U.S. crude oil prices broke above a key resistance level on Friday, according to the chief market strategist at Miller Tabak. "That paves the way for higher prices," said Bob Yawger, managing director and energy futures strategist at Mizuho Americas. "If crude oil rolls back over, breaks below that level — that's going to tell you that I'm wrong. "And that tells me that if he's buying a stock that's highly leveraged to the price of oil, he believes oil prices are going higher." Just on Friday, Houthi militants claimed responsibility for a missile attack on an oil tanker, while a Ukrainian drone attack on a Russian fuel terminal on the Baltic Sea helped push oil prices higher earlier in the week.
