VLO enters the back half of May with its most bullish options positioning in a year — and a price chart that's earning it.
The stock has climbed 6.3% on the week to $262.62, adding to a 17.4% gain over the past month. That move puts it ahead of close peers MPC (+4.4% on the week) and PSX (+4.0%), both of which have tracked the sector recovery without fully matching VLO's momentum. The story here is less about short-side pressure and more about what happens when a stock reprices hard and options traders rotate decisively to the bull side.
Options positioning has flipped to the most aggressive call-heavy posture of the past year. The put/call ratio has fallen to 0.62 — nearly two standard deviations below its 20-day average of 0.71 — and this is the lowest reading in the past 52 weeks, with the prior-year high sitting at 1.78. That reversal is striking in context: just six weeks ago, in mid-April, the PCR was running above 1.0 with investors buying downside protection. Now the same investors are leaning hard into calls. The shift coincides almost exactly with the stock's acceleration off the April lows.
Short interest tells a much quieter story. Bears hold only 2.9% of the free float short, down roughly 15% over the past month after a notable flush in late April — shares short dropped from above 10 million to below 8.75 million in a matter of days around April 23rd-24th. The borrowing market reflects that retreat: cost to borrow is minimal at 0.48%, and availability is extraordinarily loose at over 2,500% of short interest. There is no squeeze pressure here, and no sign that the remaining shorts are under stress.
The Street's tone has been predominantly upgrades-to-target, though conviction is mixed. Since April, the broad direction across Barclays, BMO, Piper Sandler, UBS, and Citigroup has been upward target revisions — reflecting improved margin expectations as refining differentials widened. The outlier is Wolfe Research, which initiated an Underperform in late April with a $203 target, the most bearish voice in the current analyst set. The consensus mean price target of $256.26 now sits slightly below the current price of $262.62, meaning the stock has effectively run past the average analyst's 12-month view. Morgan Stanley raised its target to $222 in late April — still well below the current price — signalling persistent caution from at least one bulge bracket. The forward PE of 10.6x and EV/EBITDA of 7.1x remain undemanding for a name that has printed an 80th-percentile EPS surprise track record, but those multiples have been compressing in recent weeks as the price run has moved faster than earnings revisions.
The most recent earnings history offers relevant context. Following the Q1 report on May 7th, the stock added 1.8% the next day and extended to +3.4% over the following week — a muted but positive reaction. The prior print (April 30th) moved the other way, with a 1.8% drop on the day that extended to nearly 6% over five sessions. That alternating pattern underscores how sensitive VLO remains to quarterly margin capture relative to expectations. The next event is scheduled for July 30th.
With the stock now trading through consensus price targets and options sentiment at a year-high bull extreme, the setup into summer refining season is less about whether the rally has been justified and more about whether Q2 crack spreads can deliver the margin beats the call-buyers are priced for.
