They do, but refiners do not always make a profit.
Do yourself a favor and study the history of refiners.
It's only a few years ago they were all disaster investments.
It's a cyclical industry and they will bust again (for example if WTI oil price spikes).
Right now they are in a boom, so buying here is buying at the top of the cycle (like buying internet stocks in 1998 - you got one more year of profits in 1999, but those who didn't cash out before 2000 got killed).
