Investors are loving ex-US international equity exchange traded funds this year. One of the primary drivers of that trend is that stocks in developed and emerging markets outside the U.S. are more attractively valued than the S&P 500 and other major U.S. benchmarks. In fact, some of the top asset-gathering ETFs this year are funds tracking stocks in developed markets outside the U.S.

Ex-US developed market equity exchange traded funds have been favored destinations for investors this year. Some smart beta ETFs offering investors new ways to view developed market stocks. That includes the Oppenheimer International Revenue ETF (NYSEArca: REFA), which debuted in July.

REFA looks to outperform the widely followed MSCI EAFE Index. Weighting stocks by revenue, as REFA does, can provide advantages for investors.

REFA is up 6.6% since coming to market, including a solid fourth-quarter performance of almost 5%. The ETF tracks the OFI Revenue Weighted International Index. A sound case for ex-US developed markets stocks remains.

“It is clear that the U.S. equity market is certainly not inexpensive. But valuation, both when it’s attractive and unattractive, is not a reason for buying or selling in and of itself. Investors need a catalyst. Currently, the catalyst for looking outside of the United States may be found in recent improvements in economic data. Manufacturing activity outside of the United States seems to have been steadily improving since the midpoint of last year,” according to Oppenheimer research published earlier this year.

Investors have jumped on the smart beta investment train for a number of reasons, including risk reduction, return enhancement, improved diversification, cost savings, specific factor exposure and income generation. Looking back, some of these factor-based or smart beta strategies have been adopted by many investors over the years.

REFA allocates over 31% of its weight to Japan and 13.7% to the U.K., two markets that are attractively valued relative to the U.S. France and Germany, the Eurozone’s two largest economies, combine for over 26% of the ETF’s weight.

OppenheimerFunds also offers a suite of revenue-weighted ETFs that specifically focus on companies with high revenues, including the Oppenheimer Large Cap Revenue ETF (NYSEArca: RWL), Oppenheimer Mid Cap Revenue ETF (NYSEArca: RWK), Oppenheimer Small Cap Revenue ETF (NYSEArca: RWJ), Oppenheimer Ultra Dividend Revenue ETF (NYSEArca: RDIV), Oppenheimer Financials Sector Revenue ETF (NYSEArca: RWW), Oppenheimer ESG Revenue ETF (NYSEArca: ESGL) and Oppenheimer Global ESG Revenue ETF (NYSEArca: ESGF).
