The Invesco Dorsey Wright Technology Momentum ETF (PTF) seeks to replicate the performance of the Dorsey Wright Technology Technical Leaders Index. Typically, the fund allocates at least 90% of its total assets to the holdings within this index. The index's objective is to pinpoint companies exhibiting significant relative strength (momentum), drawing at least 30 securities from the broader NASDAQ US Benchmark Index. Relative strength is defined as a security's performance comparison against its peers within a specified market over a given period. Both the fund's portfolio and the index's constituents are rebalanced and reconstituted each quarter.
