Will European stock ETFs outperform US stock ETFs? (EEM, IEV, EWO, EWK, EWQ, EWG, EWI, EWN, EWP, EWD, EWU, VGK)

Yes, according to this article (free registration required) from The NY Times. Look at this chart from the article:

EFA is the ticker symbol of the ETF (issued by Barclays iShares) that tracks the MSCI index of large cap European, Japanese and Australasian developed market stocks, the index used by most US investors to cover non-US developed market stocks in their portfolios. The expense ratio of the ETF is 0.35%. But more targeted ETFs for Europe are:

• VGK, Vanguard's European Stock Index ETF with an expense ratio of 0.18%;
• IEV, the S&P Europe 350 Index with an expense ratio of 0.60%;
• EZU, the MSCI EMU Index Fund with an expense ratio of 0.59%.

It's also worth considering single country ETFs:

• EWO, MSCI Austria Index Fund, expense ratio 0.59%.
• EWK, MSCI Belgium Index Fund, expense ratio 0.59%.
• EWQ, MSCI France Index Fund, expense ratio 0.59%.
• EWG, MSCI Germany Index Fund, expense ratio 0.59%.
• EWI, MSCI Italy Index Fund, expense ratio 0.59%.
• EWN, MSCI Netherlands Index Fund, expense ratio 0.59%.
• EWP, MSCI Spain Index Fund, expense ratio 0.59%.
• EWD, MSCI Switzerland Index Fund, expense ratio 0.59%.
• EWU, MSCI U.K Index Fund, expense ratio 0.59%.
