iShares Global Comm Services ETF(AMEX:IXP)

IXP delivers a market-cap weighted portfolio of global communication services stocks as defined by S&P. The well-established fund changed indexes on June 24, 2019 to a capped version which at quarterly rebalance limits single positions at 22.5% and caps aggregate positions over 4.5% at 45% total. Such index variants are not unusual and still allow for plenty of single-name impact. Moreover, stock selection resulting from the underlying industry classification system (GICS ) is likely a larger driver of returns. (Major changes in GICS communication sector occurred in Fall 2018.) The index pulls from a universe of 1,200 global stocks selected by S&P.
