“With such limited capacity, strong inflows into frontier-markets stocks will likely drive markets higher. However, any sudden pull-back by foreign investors could result in brutal declines,” said Morningstar ETF analyst Patrica Oey in a recent note.

Her comments jibe with what other market observers have said about frontier stocks. Earlier this year, Sam Vecht, who manages the BlackRock Frontier Investments Trust, said that the time is now to invest in frontier markets because as more Westerners learn of the advantages offered by these markets, volatility will increase.

For their part, ETF issuers have not been deterred by an increase in volatility that has yet to materialize in earnest. The EGShares Beyond BRICs ETF (NYSEArca: BBRC) recently switched to a new index to boost the fund’s frontier markets exposure. Two weeks ago, Global X introduce the Global X Next Emerging & Frontier ETF (NYSEArca: EMFM) and that ETF already has more than $12.3 million in assets under management.

Perhaps the biggest concern about frontier market indices is one that will certainly come to pass: The loss of Qatar and the United Arab Emirates to emerging markets status. Those nations’ stocks have been stellar performers and the two are seen as economically advanced and politically stable relative to the likes of Argentina and Nigeria.

How that promotion affects FM, in particular, will be worth watching. FM is benchmarked to an MSCI index and it what MSCI that promoted Qatar and UAE to emerging market territory. Currently, the two countries combine for over 32% of the fund’s weight. When they leave in 2014, Kuwait and Nigeria will dominate FM.
