“I think as we move further in the year and people start looking at 2016 and we start looking again back at growth, these companies are really going to have that value,” Gibbs said.

Since the sector’s sell-off, many energy names are trading at cheaper values relative to the broader market. For instance, IEZ has a 17.49 price-to-earnings ratio and a 1.28 price-to-book while XES shows a 15.04 P/E and a 0.92 P/B. In contrast, the S&P 500 index is trading at a 18.42 P/E and a 2.57 P/B.

Moreover, Gibbs points out that energy stocks provide a more attractive 3% dividend yield, whereas the S&P 500 has a 2% yield.

“So I just see a lot more potential appreciation, versus the broader index, for energy,” Gibbs added.
