Invesco S&P 500 Revenue ETF(AMEX:RWL)

RWL takes the securities of the S&P 500 Index, an index consisting of 500 large-cap US companies across various industry groups. The fund reweights each company by its revenue rather than its market cap. It follows that RWL underweights technology in favor of consumer firms, which generate large sales, but unlike some other fundamentally-weighted funds, it ignores profit margins. Overall, RWL delivers a decent, if revenue-biased, approximation of the market. The index constituents are rebalanced on a quarterly basis. Prior to June 4, 2018, the funds underlying index was called OFI Revenue Weighted Large Cap Index.
