The BLDRs Europe 100 ADR Index Fund (ADRU) is a remarkably small fund, for being four years old, with only $35 million in assets. It owns the 100 stocks that make up the Bank of New York Europe 100 ADR Index. It would be easy to read through that name without noticing something I think is important, which is that it owns only ADRs. Some numbers: ADRU yields 2.04%, has a beta of 0.95, a standard deviation of 9.49 and has a 0.70 correlation to the S&P 500

iShares MSCI EAFE Index Fund (EFA) is the most popular and people usually don't look past this one when they want european exposure through an ETF.

The Vanguard European ETF (VGK) has 621 holdings and the lowest expense ratio, 0.18%.

The streetTracks Dow Jones Stoxx 50 (FEU) has surprisingly few assets being four-years-old. This fund is much more concentrated than the others with only 50 holdings; the biggest of the European big stocks. The average weighted market cap is $109 billion. The top two holdings, again BP and HSBC, account for 10% of the fund.

WisdomTree Europe Dividend Index Fund (DEB) has 1088 holdings weighted by dividends

WisdomTree Europe High-Yielding Equity Index Fund (DEW) is a sort of subset of DEB. DEW owns the 313 biggest dividend payers out of the 1088 holdings in DEB.

One of the bigger funds in the space is the iShares S&P Europe 350 Index Fund (IEV). It is obviously very broad based. Like all of these funds, the U.K. is the largest country and the financial sector is by far the largest. BP and HSBC are the two largest holdings. The fund is very unremarkable except that it has been the best performing of the bunch since the listing of the two WisdomTree funds. IEV only yields 1.83%, has a beta of 0.94, a standard deviation of 9.03 and a 0.72 correlation to the S&P 500.
