PUI provides an alternate technical - take on US utilities firms. It follows a Dorsey-Wright relative strength index that selects and weights stocks by price momentum. The fund reaches beyond our definition of US utility companies. Its concentrated, momentum-based portfolio actually carries lower market risk than our benchmark. Overall, PUI is a valid alternative to vanilla US utilities exposure. The fund uses a full replication indexing strategy, meaning PUI will generally invest in all of the stocks of the underlying index and in proportion to the weightings. Investors should consider all-in costs of holding the fund. The fund is reconstituted and rebalanced quarterly. Prior to August 28, 2023, the ETF's name was Invesco DWA Utilities Momentum ETF.
