Another producer, Hess Corp, is due to report Wednesday, while ConocoPhillips, the world's largest independent oil and gas producer, beat analysts' estimates for profit in the third quarter when it reported Thursday, citing higher oil prices but also cost cuts.

Recent losses aside, some equity strategists consider oil to be in a bullish cycle and expect prices to rise further over the next year. Energy shares have sharply underperformed oil prices so far this year, suggesting there is room for shares to rise further. For graph

"People are still thinking we're at $40 a barrel oil. We're not," said Robert Lutts, president and chief investment officer at Cabot Wealth Management in Salem, Massachusetts, which owns shale producer Diamondback Energy and other names. "People are misjudging the balance between supply and demand," said Lutts, who sees oil prices heading towards $80 to $90 a barrel within a year. U.S. crude settled at $67.59 on Friday. Even with the recent selloff, U.S. oil prices are up roughly 11 percent for the year to date, while the S&P 500 energy index is down about 8 percent for 2018 and market leader Exxon is down about 7 percent.

Some money managers also consider energy shares to be more attractive buys now, with investors fleeing high-flying technology and Internet names in the recent stock market sell-off and seeking value-oriented names.

Others say it is still too soon for a bullish call on energy.

"To get a sustained move in oil stocks, where they consistently outperform other sectors and where the sector is actually growing as a component of the S&P 500, you need a lot of things like the supply constraint and global growth. We're not there right now," said Bucky Hellwig, senior vice president at BB&T Wealth Management in Birmingham, Alabama.
