As providers look for new niche parts of the market to occupy, the number of unconventional funds will continue to increase and, according to an article on Benzinga, the following 10 are some of the most eccentric to date.

The staff at Benzinga highlighted the following funds—some of which are shut or haven’t yet launched—for their, very “original” ideas:

• Oklahoma Exchange-Traded Fund
• ETRACS Fisher-Gartman Risk On ETN (NYSEArca: ONN)
• Global X Pakistan ETF
• iPath DJ-UBS Natural Gas TR Sub-Index ETN (NYSEArca: GAZ)
