The last time Delek US Holdings executives spoke to an investor conference, shares of the Brentwood-based oil refiner and marketer spiked big time. They popped again Tuesday without such a catalyst — rising 4.6 percent to another all-time high — but traders looking for a reason to jump in may have one. On Thursday, execs will address the Credit Suisse Energy Summit in Vail. For an early peek at their presentation, click here.

Despite doubling since last July, Delek shares could have farther to run and not just based on momentum. They are still valued at just nine times their projected 2013 earnings and analysts have hiked their full-year estimates to $3.95 from $3.49 in the past month based on widespread optimism in the refining space.
