iShares Global Water Index ETF (CWW.TO)

Qué hace este fondo

The fund offers comprehensive coverage of the global water industry in an efficient wrapper. The fund starts with all eligible securities from the S&P Global BMI Index that are classified in either water equipment & materials or water utilities & infrastructure clusters. To identify industry relevance, each company within both clusters will be assigned an exposure score based on its business description and most recent reported revenue. The 25 largest companies with an exposure score of 1 from each cluster will be selected for inclusion. However, if fewer than 25 companies have an exposure score of 1, the fund will select the largest companies with a 0.5 exposure score until the portfolio contains a total of 25 constituents for each cluster. Stocks are weighted by market-cap within each bucket and are constrained, such that securities with an exposure score of 1 are capped at 10% and those with 0.5 exposure score are capped at 5%. Index rebalancing occurs semi-annually.
