While the Federal Reserve is tightening its monetary policy, other central banks are enacting additional easing. Consequently, exchange traded fund investors may find better growth opportunities in overseas markets.

David Garff, president and chief investment officer of Accuvest Global Advisors, who specializes in global portfolios, recently pointed out that the top performing countries were those that received the most economic stimulus from their respective central banks, writes Noah Hamman, CEO of AdvisorShares, for ThinkAdvisor.

With the U.S. cutting back on its quantitative easing plan, investors are beginning to pull away from U.S. stocks and are turning toward foreign investments. For instance, the Vanguard FTSE Europe ETF (NYSEArca: VGK), iShares MSCI EMU ETF (NYSEArca: EZU) and Vanguard FTSE Developed Markets ETF (NYSEArca: VEA) are among the top leaders in ETF fund flows year-to-date.

VGK tracks European markets. EZU specifically follows Eurozone countries. VEA includes global developed countries, excluding the U.S. and Canada.

Additionally, Hamman argues that foreign investments are capturing a rebalancing effect after the performance divergence caused investment portfolio imbalances, particularly after the outperformance in U.S. equities last year. The S&P 500 Index shows a price-to-earnings ratio of 16.67, whereas VGK has a P/E of 15.38, EZU has a P/E of 15.46 and VEA has a P/E of 14.43.
