“All of these policies are going in different directions, and they’re probably not all going to be winners,” Haefele said. “You don’t want to bet on just one of these central banks getting it right—you want to diversify it.”

Investors who are interested in broad international exposure have a number of ETFs to choose from. For instance, the Vanguard FTSE All-World ex-US (NYSEArca: VEU), iShares MSCI ACWI ex U.S. ETF (NasdaqGM: ACWX) and SPDR MSCI ACWI ex-US ETF (NYSEArca: CWI) focus on international markets sans U.S. exposure.

Among the global picks, BlackRock is eyeing the emerging markets as an attractive destination. The money manager has issued positive ratings for stocks in the developing markets and Asia, excluding Japan.

Investors can also take on broad exposure to these emerging Asian economies through region-themed ETFs. For instance, the SPDR S&P Emerging Asia Pacific ETF (NYSEArca: GMF) provides broad exposure to emerging economies in the Asian Pacific, and the iShares MSCI All Country Asia ex Japan ETF (NYSEArca: AAXJ) excludes Japanese and Australian stock exposure and tilts toward more emerging economies as well.

Broader emerging market plays include the iShares Core MSCI Emerging Markets ETF (NYSEArca: IEMG), Vanguard FTSE Emerging Markets ETF (NYSEArca: VWO), Schwab Emerging Markets Equity ETF (NYSEArca: SCHE) and WisdomTree Emerging Markets Equity Income Fund (NYSEArca: DEM).
