XLC offers exposure to the Communication Services sector that was defined by the September 2018 changes to the Global Industry Classification Standard (GICS). The fund includes all members of the former telecom sector (expanded to include internet service providers), as well as media & entertainment companies previously classified in the consumer discretionary or tech sectors. This latter industry group includes many heavyweights such as Facebook, Alphabet, Netflix, and Disney. XLC is one of the eleven Select Sector SPDR funds, which draw their holdings from the S&P 500 index. Holdings are weighted by market cap, subject to a capping methodology that ensures no single security exceeds 25% at each quarterly rebalance.
