Buyers are clearing resistance rather than stalling at it: Phillips 66 reached $281.60 on October 8, 2.7% above the prior 52-week peak set on September 17.

The latest leg extends a climb that steepened sharply in the final months of the 52-week window.

Consecutive 52-week highs in quick succession signal that buyers are absorbing supply at each new level. The September 17 peak held only three weeks before being surpassed, so demand has not stalled at these prices.

At roughly $112 billion in market value, one of the largest independent refiners in the United States, a move this size is not thin-volume noise for anyone tracking the energy sector.
