YTD Gains as of December 26: 60.54%

Next on our list of the best-performing energy stocks is Delek US Holdings, Inc. (NYSE:DK), a diversified downstream energy company specializing in petroleum refining, asphalt, renewable fuels, and logistics.

On December 12, Mizuho raised its price target on Delek US Holdings, Inc. (NYSE:DK) from $45 to $51, indicating a significant upside potential of over 72% from the current share price. The firm also maintained its ‘Outperform’ rating on the DK shares.

The adjusted target comes as Mizuho updated its ratings and targets in the exploration and production sector as part of its 2026 outlook. The firm noted that the energy sector experienced a challenging year in 2025, primarily due to oversupply in gas storage and the oil market, which drove prices to a multi-year low. However, the analyst still sees some ‘underappreciated’ value, particularly in E&P,  that could start to be realized next year.

As a result, Mizuho recommends that investors reallocate their risk toward oil E&Ps, with a selective bias toward gas stocks, given the commodity’s high demand driven by rising LNG exports and record power demand. That said, Mizuho maintains a neutral stance on the refining sector.

Delek US Holdings, Inc. (NYSE:DK) has surpassed estimates in each of its three quarters so far in FY 2025, and the company recently raised its EBITDA guidance to $500-$520 million for the year. The share price of DK has soared by over 60% since the beginning of 2025.
