iShares Global Infrastructure ETF [IGF]

IGF is one of the oldest funds in the global infrastructure segment. With a broad definition of infrastructure firms, it offers a reasonable take on the segment as it holds diversified positions across three sectors: energy, transportation, and utilities. After categorizing eligible securities into three sectors, the fund selects the largest stocks according to market cap, having 15 stocks from the emerging markets with no more than 10 for any single sector and 60 stocks from the developed markets. Overall, IGF holds a concentrated portfolio of 75 global infrastructure companies, subject to count and weight constraints such that the transportation and utilities sector each consists of 30 securities having 40% weight and the energy sector contains 15 securities taking 20% weight of the portfolio. Stocks are cap-weighted within each sector, with no individual security having a weight greater than 5%. The index rebalancing occurs on a semi-annual basis.
