Emerging markets are expected to post growth around 5.9% in 2013, compared to 2% for developed markets such as the U.S. Several exchange traded funds are available to tap into emerging market stocks which are showing cheap valuations.

“Many investors are attracted to emerging-markets equities, as they expect these countries’ higher GDP growth rates to drive strong equity returns. It appears this has been the case, with the MSCI Emerging Markets Index returning an annualized 16% over the past 10 years to Nov. 30, 2012, far outpacing the S&P 500’s 6%. In hindsight, emerging-markets equities’ higher-than-expected growth rates, followed by significant (price/earnings and price/book) valuation multiple expansion, were the main drivers of this performance,” Patricia Oey wrote for Morningstar.

According to Zacks, emerging market ETFs have underperformed broad market ETFs such as the SPDR S&P 500 (NYSEArca: SPY) and the Dow Jones Industrial Average (NYSEArca: DIA). This is the first time in 10 years emerging market ETFs have underperformed during a global rally. [Breaking Down First Quarter ETF Flows]
