Oil
Oil futures settled lower for a second straight session on Wednesday, easing back after a run-up early this week to the year's highest prices.
"We do feel some consolidation is warranted until we see the next leg higher," Tariq Zahir, managing member at Tyche Capital Advisors, told MarketWatch. Still, "the weight of the continued supply production cut through the end of the year by Saudi Arabia and Russia...is not a matter of if, but a matter of when prices will break $100."
