I had posted before that the earnings of refinery companies depend on crack spread, which is the differential between the price of crude oil and petroleum products extracted from it. To give you an idea how that impact the earnings of these companies, I have created a graph comparing their earnings for the period Mar 2014 to Mar 2017 with the crack spread for that period. As you can see the earnings dropped whenever crack spread dropped.

Now, crack spread is again dropping. The smart money is again selling these stocks since they have rallied so sharply in May. If you have good paper profit sitting in these stocks, you should consider SELLING INTO STRENGTH.
