A pre-market move of close to 4% is unusual for a refiner the size of Valero Energy, signaling that something meaningful is driving conviction among early traders.

For investors already holding a position, the move raises the question of whether this is the beginning of a sustained re-rating or a single-session pop that gives back ground by the afternoon. Keeping a close eye on volume and price action in the first hour of regular trading will be the clearest early signal of which scenario is playing out.
