iShares Inc iShares MSCI Mexico ETF(AMEX:EWW)

EWW is passively-managed to provides vanilla exposure to the Mexican stock market. The fund holds a concentrated portfolio of all-market-capitalization Mexican companies. The index is weighted by market cap, and aims to meet the Regulated Investment Company (RIC) requirements by employing a capping methodology so that no individual constituent exceeds 25% of index weight and the aggregate weight of constituents with over 5% weight in the index are capped at 50% weight of the portfolio. While the fund retains concentrated exposure, this capping process tilts the fund slightly smaller and leads to minor sector tilts. The index rebalancing occurs on a quarterly basis.
