Oil prices were mixed on Tuesday, with U.S. crude gaining and Brent crude slumping, as investors prepared for a key meeting of the OPEC producer group next week.
U.S. West Texas Intermediate crude futures ended Tuesday's session up 26 cents at $66.36. Brent crude futures were down 60 cents at $75.86 a barrel by 2:21 p.m. ET.
Crude future were in line with the broader financial markets, which were largely unruffled by a U.S.-North Korea summit aimed at the denuclearization of the Korean peninsula.
"I was looking for an up day (for WTI) — in just a few weeks it had fallen from around $73 (a barrel) to $65...and even for the window of seasonal decline, that's a big move to go uncorrected," said Walter Zimmerman, chief technical analyst at ICAP-TA.
He said short-covering ahead of next week's OPEC meeting also provided some support to prices.
