Has Tesoro Corporation (TSO) Become the Perfect Stock?

Since we looked at Tesoro last year, the company has held onto all three points it gained from 2011 to 2012. The stock has absolutely soared, up about 120% over the past year.

Tesoro Corporation (NYSE:TSO) has enjoyed perfect conditions in the refining industry lately. Because of the massive rise in production of domestic crude, refineries that obtain oil supplies that are priced based on West Texas Intermediate benchmarks have enjoyed high margins compared to peers that have to rely on imported oil using higher-cost Brent crude. Moreover, refined-product pricing has been extremely favorable, leading to a powerful combination for profit growth.

In response to these conditions, Tesoro has put its profits to work, inking a deal that made it the largest refiner on the West Coast. The $2.5 billion deal with BP plc (ADR) (NYSE:BP) includes not only an increase to the company’s refining capacity but also more than 800 Arco gas stations to Tesoro’s marketing arm. Yet the acquisition is still on hold pending a close look from regulators concerned about potential antitrust issues.

In its most recent quarter, Tesoro missed earnings estimates even though it was able to raise its refining margins substantially from the year-ago period. But looking forward, Tesoro’s plans to lock in rail transport to bring cheap domestic crude to its refineries on the West Coast should help it capitalize on favorable price differentials compared to imported Brent crude. Phillips 66 (NYSE: PSX) has made a similar rail-based move to bring cheap oil to the East Coast that also promises a positive impact on profits, and Tesoro expects the same gains.

For Tesoro Corporation (NYSE:TSO) to improve, it needs to keep working on profitable growth and then consider boosting dividend payouts to shareholders. As long as favorable pricing conditions last, Tesoro Corporation (NYSE:TSO) should keep delivering strong returns to investors.
