On CAPS, 97% of the 422 members who have rated Vanguard Energy believe the ETF will outperform the S&P 500 going forward. These bulls include crisafugate and jbungard4.

Having gotten on board last year, crisafugate touched on the tailwinds working in the ETF's favor: "Peak energy has arrived with no alternatives. People's addiction to energy combined with the increasing demand for energy will cause the value of energy stocks to increase."

Vanguard Energy, in particular, sports an expense ratio of just 0.24%. That's lower than that of other energy ETFs like iShares Dow Jones U.S. Energy (0.47%) and iShares S&P Global Energy (0.48%).  

CAPS member jbungard4 expands on the inexpensive opportunity:

Energy stocks are a long-term winner. World-wide demand for energy continues to increase while energy resources are increasingly under pressure to meet this insatiable demand. Vanguard's Energy ETF captures the energy sector as a low-cost pure play.
