This year, international stocks are beating their U.S. counterparts as both the widely followed MSCI EAFE Index and the MSCI Emerging Markets Index are topping the S&P 500. Several of this year’s top asset-gathering ETFs are ex-US developed and emerging markets funds.

“That small-cap exposure has lifted IEFA to an 18.7% gain in 2017, compared with 17.8% for EFA, according to Morningstar. Other funds investing in non-U.S. developed markets include the $60 billion Vanguard FTSE Developed Markets ETF (VEA) at 0.08% and the $10.9 billion Schwab International Equity ETF (SCHF) at 0.06%, while iShares might be looking to compete with itself even further, launching iShares Core MSCI Developed Markets ETF (IDEV), including Canada, for 0.07% in March,” according to Journal.

IDEV is off to a solid start as highlighted by nearly $66 million in assets under management in less than six months on the market.
