Over 40 countries were represented in ACWI as of the end of 2013, according to iShares data, but the ETF is heavily tilted toward developed markets with eight of its top-10 country weights being developed economies. The U.S. accounts for nearly 48% of the fund’s weight. Nine of the ETF’s top-10 equity holdings are U.S.-based companies with Nestle (PK: NSRGY) being the outlier.

There is an ex-U.S. equivalent to ACWI, the $1.5 billion iShares MSCI ACWI ex U.S. ETF (NasdaqGS: ACWX). ACWX has slightly outpaced ACWI over the past month, gaining 4.2%. The U.K. and Japan combine for over 30% of ACWX’s weight.
