SLX is one available global steel ETF targeting not only steel producers but also the companies that service and supply them, giving it exposure to industries outside the scope of its benchmark. The fund will normally invest at least 80% of its total assets in companies involved in this particular sector, which may include small- and midcap companies as well as foreign and emerging market issuers. Reviewed quarterly, the index is market-cap-weighted while taking into account the following adjustments: (i) individual component weights may not account for more than 20% of the total index value and (ii) the aggregate weight of such components individually representing more than 5% of the total index value may not account for more than 50% of the same.
