FCOM is one of ten October 2013 launches from Fidelity that track MSCI sector indexes. The fund targets the broad US communication services sector, as classified by GICS, to include both the telecommunications and the media and entertainment industry. FCOM captures stocks of all capitalization within the segment but weights the holdings in the portfolio based on market-cap. The funds manager uses a representative strategy, which means the ETF may not hold all of the securities of the index or in the exact proportion. Certain investment limits are applied for RICs to help ensure diversification, such that no group entity exceeds 25% of index weight and the aggregate weight of issuers with over 5% weight in the index are capped at 50% of the portfolio. The index is rebalanced quarterly
