The Invesco S&P 500 Revenue ETF (RWL) aims to mirror the performance of the S&P 500 Revenue-Weighted Index, committing a minimum of 90% of its total assets to the index's constituent securities. This index employs a systematic methodology to adjust the weight of companies within the standard S&P 500, allocating proportionally more to those generating higher revenue, while ensuring no single company's weighting surpasses 5%. Both the ETF and its underlying index undergo quarterly rebalancing.
