Jim Cramer's Stop Trading: HFC MPC VLO LO

NEW YORK (TheStreet) -- Citigroup upgraded Alon USA Partners LP (ALDW) to hold from buy but TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said Monday he is focused on other names in the energy sector.

Specifically, he is watching HollyFrontier Corp. (HFC), Marathon Petroleum (MPC), and Valero Energy (VLO). 

The refiners continue to get European pricing on oil at a time when there is also a "glut" of oil in the Permian basin, Cramer said, So these companies' margins are "exploding." Cramer  said the stocks should continue to perform well since they are undervalued. They report earnings in May. 

He said Marathon Petroleum could climb to $100. 

Turning to Lorillard (LO), Goldman Sachs upgraded the stock to buy from hold. Cramer said the stock is "not expensive," and could be considered a takeover target. The company controls half of the "no-smoke" cigarette market and the stock can go higher, he concluded.
