First Trust Cloud Computing ETF(NASDAQ:SKYY)

SKYY was the first mover in the ETFs space to offer exposure to cloud computing stocks. Its index takes all stocks that fall into any one of 3 groups per its definitions: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). The index applies additional size, liquidity, and tradability screens. The index assigns scores of 3, 2 and 1, respectively, to these groups. A stock can receive more than one assignment. A stocks weight in the index is its score divided by the sum of all scores which is then modified so that no single security exceeds 4.5% weight. Firm size (market cap) has no direct bearing in weighting. Prior to June 24, 2019 the fund tracked the ISE Cloud Computing Index which used a different methodology.
