As energy stocks continue to gain favor among investors this year, CNBC Pro used technical and fundamental analysis to find the names that may be primed to rally the most.
So far in 2015, the top five broad energy equity ETFs received $3.4 billion in fund flows, as investors got behind the sector after a 40 percent rally in oil prices from a low in March.
"Oil's price plunge has leveled off after a stressful end of 2014, and with it we've noted investors returning into the energy equity sector," wrote Eric Mustin, vice president of ETF trading solutions at WallachBeth Capital.
Similarly, last week Oppenheimer upgraded its rating on the energy sector to favorable from neutral, joining other Wall Street firms that have a bullish stance such as Goldman Sachs, JPMorgan, Bank of America and Morgan Stanley.
But not all stocks in the sector were created equal. Some will be much more volatile than their peers. And others may not benefit as much if crude continues to rally.
