No surprise, really. Refining margins have been under pressure for several months now and it's taking it's toll of earnings and stock prices. Analyst consensus for VLO 2Q 2016 is nearly 30% less than year ago earnings. There appears to be no catalyst for change in the immediate future. That said, I'm long here. The company is going through a downturn and still posting decent profits. When the supply/demand equation improves in the distillate market you'll see a $70-80 range for VLO.
