Valero Energy

The petroleum refining company reported on May 1 a first-quarter loss of $432 million, or 78 cents a share, a reversal from year-earlier income of $104 million, or 18 cents a share.

"We retain our view that the US refiners are on the cusp of a secular rerating over the next several years and still believe it is too early to call the end to seasonal strength of the US refining sector," Bank of America Merrill Lynch analysts wrote in a May 2 report. "In our view, WTI-Brent will widen with North Sea downtime in the coming weeks and with a tough quarter behind them alongside organic growth and significant leverage to exports and low natural gas prices, VLO remains our Top Pick in the sector."
