With so many exchange traded funds (ETFs) now available, it is not surprising that some funds have flown under the radar of most investors, even as they’ve been growing into investment behemoths.

Not every ETF idea that comes out of the well-established ETF industry names is widely accepted by the investment community, remarks Gary Gordon for ETF Expert, but some smaller fund providers have been churning out rather successful products. Take Global X, for example. The provider has launched a number of first-to-market products since 2009 that investors seem to have taken a liking to.

Global X‘s Global X InterBolsa FTSE Columbia 20 (NYSEArca: GXG) has become one of the top-performing equity ETFs in the last 12 months, with 34.1% in gains. It also has $174.6 million in assets. [Colombia ETF: A Stable Country Brings In the Foreign Investors.]

Additionally, the Global X China Consumer ETF (NYSEArca: CHIQ) was one of the fastest funds to reach $100 million in assets from inception.

The community is also intrigued by the Global X Lithium (NYSEArca: LIT) ETF that Global X launched this year. The fund invests in both lithium miners and battery producers. The fund has already amassed $76.2 million in assets. [Lithium ETF Gets Institutional Attention.]

Other notable Global X funds include:

Global X FTSE Nordic 30 (NYSEArca: GXF). GXF holds 30 of the largest, most liquid companies in Sweden, Finland, Denmark and Norway. The fund is up 14.5% in the last 12 months and recently hit a high on Oct. 23.

Global X Copper Miners ETF (NYSEArca: COPX). Copper prices are up more than 35% off their  summertime lows. COPX holds 30 companies that deal with exploring, mining and/or refining copper and have increased profit margins. The fund is in the top 5% of all ETFs based on relative strength.
