Now I understand that the energy sector has come under pressure lately, but I remain optimistic about the long-term prospects of several mid-cap refiners—many of which I’m currently recommending in my Emerging Growth newsletter.

Here’s a taste of what I consider to be the best energy plays on the market:

CVR Energy (CVI) is one of our top energy plays. It operates two main businesses; refining and marketing transportation fuels as well as nitrogen fertilizer products in the U.S. Shares of CVR went on a tear in early May after it announced strong first quarter results, including a whopping 28% earnings surprise, but have recently spent pulled back due to investor worries regarding oil spreads. Some of the dip was also due to the company’s $6.50 per share special dividend, so I see this as a buying opportunity. CVI is an A-rated Buy.

My second energy recommendation is a refiner that benefits from the discount spread between WTI Midland and WTI Cushing, and the company has beat on the bottom line for six straight quarters. This company also runs a network of fuel and convenience stores that should benefit from higher summer travel. The stock yields 2% and is currently trading at a very attractive price.

Plains All American Pipeline (PAA) remains my answer for a reliable dividend payer and pipeline play. Plains All American has been a key player in what I like to call the “black gold rush,” which was the $20 billion initiative to build, expand and reverse two dozen pipelines in recent years. This was in response to the increased inland oil output caused by the shale boom, and I see strong continued upside in the stock. The stock reports earnings in early August—with its track record of earnings surprises and analyst earnings revisions this should be a strong report. PAA is a B-rated Buy.

All told, these are some of the best energy stocks out there. But that’s not to say that you should go out and load up on any and all energy stocks. Despite the catalysts that are bolstering profits for the companies I listed above, some household names have missed the boat.

In fact, you may be surprised to find out that some of the biggest names in energy are actually more trouble than they’re worth. To help keep you focused on the best profit opportunities around, here are 19 companies that you’ll want to steer clear of.
