Valero Energy Corporation (VLO) closed at $426.13 on October 23, 2026, declining 2.46% over the prior 24 hours as selling pressure weighed on the refining giant. The move extended a broader pullback, with shares also down 4.02% over the past seven days.
Despite the near-term weakness, Valero's stock has posted a gain of 12.96% over the trailing 30 days, reflecting a significant run-up heading into the latest stretch of declines. The company's market capitalization stood at $125.75 billion as of the close.
The session's retreat places VLO among energy names that have given back a portion of recent gains amid shifting market conditions. The stock's 30-day performance nonetheless remains one of the stronger readings among large-cap industrials over that span.
Traders will be watching whether the current pullback represents a consolidation of those monthly gains or the beginning of a more sustained reversal for the San Antonio-based refiner.
