Some refining stocks have already impressed to start 2015. For example, shares of Valero (NYSE: VLO) are up 3.5% while Tesoro (NYSE: TSO) has surged 9.4%. Those stocks combine for over 8% of PXE’s weight. The ETF also allocates 4.8% of its weight to Phillips 66 (NYSE: PSX), a stock some market observers see significant upside for.

PXE tracks the Dynamic Energy Exploration & Production Intellidex Index and that index is, well, dynamic. The index considers companies based on price momentum, earnings momentum, quality, management action, and value, according to PowerShares. [Contrarian ETF Ideas for 2015]
