Market Vectors Unconventional Oil & Gas ETF (NYSEArca: FRAK)

YTD Gain: 12.5%

Comment: This has been the year of the resurgent energy ETF and FRAK is no exception. The fund tracks the growing oil boom in North America as new extraction techniques help companies produce oil from shale beds and oil sands. [Capture the U.S. Oil Boom with the Unconventional Energy ETF]

That means FRAK tilts away from large integrated oil stocks such as Exxon Mobil (NYSE: XOM), but the ETF does offer ample exposure to highly liquid independent exploration and production firms such as Anadarko Petroleum (NYSE: APC), EOG Resources (NYSE: EOG) and Devon Energy (NYSE: DVN). Those stocks combine for nearly 20% of FRAK’s weight.
