Energy stocks might be on course for another fourth-quarter rally this year, in part because investors are too focused on negative headlines, according to Tamar Essner, senior energy director at Nasdaq Corporate Solutions.
"It kind of feels like deja vu of last year where energy underperformed for most of the year and then in Q4 rallied tremendously and we became the best performer in the year," she told CNBC's "Squawk Box" on Thursday.
The S&P energy sector surged about 8 percent in the final three months of 2016, dovetailing with a rise in oil prices as OPEC hammered out a deal to cut crude production.
S&P energy sector two-year performance
But the sector's fortunes have turned as oil prices sputter against a backdrop of rapidly rising U.S. production and concerns about OPEC's ability to end a crude glut. The S&P energy sector is down more than 14 percent this year, making it the second-worst-performing sector after telecommunications.
Essner did not guarantee the same late-year surge for energy stocks, but presented the bull case for the sector.
On the commodity side, rising output from the United States and OPEC members Nigeria and Libya has created a negative confirmation bias, in her view.
"Anything that's positive in the market gets overlooked, and we focus in on these negative data points," Essner said.
She noted that bearish bets on oil have recently risen while many traders have unwound wagers that prices will rise. That typically makes it harder for bears to push prices lower and increases the risk oil futures will tick higher. While oil prices will likely remain stuck in a range between $40 and $50 a barrel this year, the risk is now to the upside, Essner said.
Other analysts have recently told CNBC that the oil market appears to be caught in a feedback loop in which negative news is amplified.
The credit market also remains relatively open to drillers seeking to fund production even as energy stock prices have tanked, Essner added. That's important because 20 to 25 percent of U.S. oil output depends on access to high-yield debt, she explained.
To be sure, U.S. production growth would take a hit if credit markets tighten, she said.
