ETFs still have a long way to go when it comes to global market dominance for risk assets Nicholas Colas, chief market strategist at ConvergEx group, said an interview with the Financial Times.

Colas notes that the hot topic among U.S. ETF issuers is the difficulty in bringing new funds to market that are truly appealing to investors. Over 170 new ETFs were introduced last year, but just 17% captured $100 million in assets under management.

The bulk of the rookie $100 million AUM club can be found among two issuers: ETF Securities and Global X. The ETFS Physical Platinum Shares (NYSE: PPLT) and the ETFS Physical Palladium Shares (NYSE: PALL) gained $689 million and $599 million in AUM last year, the FT reported.

PALL and PPLT were the first ETFs backed by physical palladium and platinum introduced to U.S. investors.

Several funds introduced by Global X also eclipsed $100 million in AUM in less than a year's time, inlcuding the Global X Copper Miners ETF (NYSE: COPX), the Global X Lithium ETF (NYSE: LIT), the Global X Silver Miners ETF (NYSE: SIL) and the Global X Uranium ETF (NYSE: URA).
