Emerging-market equities have been enjoying a solid rebound from their late 2011 drubbing, but trading’s been choppy lately as investors reconsider key drivers of the rally, from commodities prices to economic conditions in the Euro Zone, U.S. and China. There’s also been concern about things more closer to home in emerging-market giants such as China and Brazil, where growth is slowing.

The emerging-market universe of exchange-traded funds is extraordinary diverse, covering various asset classes — equities, stocks and bonds — as well as broad and narrow stock groups. For instance, there’s regional and single-country funds and even sector-based ones.

The ETFs also vary widely in size, in this case from under $2 million to almost half a billion dollars in net asset value, or NAV, which is comparable to market capitalization.

Here are the ten ETFs with the biggest price gains along with their NAV, launch date and investment goal. Data comes from Morningstar. Goal information is from the individual funds. All data are through April 13, 2012.
