Low-volatility ETFs have been a hit with investors and could make even more sense for emerging markets, which are known for their higher risk and jarring price swings.

With the growing interest for managing risk, investors may consider low-volatility emerging market strategies, like the iShares MSCI Emerging Markets Minimum Volatility ETF (NYSEArca: EEMV) and the PowerShares S&P Emerging Markets Low Volatility Portfolio (NYSEArca: EELV), writes Morningstar analyst Patricia Oey.

While the iShares and PowerShares funds may seem similar, they are constructed differently. EEMV’s index tries to create a portfolio with the lowest volatility through 200 holdings from the MSCI Emerging Market Index. EELV is a low volatility portfolio that selects the 200 least volatile stocks out of the S&P Emerging BMI Plus LargeMidCap Index and weights holdings by the inverse of its volatility.

Compared to EEMV, EELV does not include sector or country constraints on weightings. The PowerShares fund has also been underweight energy and tech companies while overweighting defensive utilities and consumer staples.

The low-volatility emerging market ETFs have seen lower volatility over the last five years relative to the MSCI Emerging Markets Index. For instance, in the 2008 crisis, EEMV’s and EELV’s benchmark indices dropped 42% and 34%, respectively, compared to the 53% decline in the MSCI Emerging Markets Index.
