The Invesco Water Resources ETF (PHO) aims to mirror the performance of the NASDAQ OMX US Water Index. This fund typically allocates at least 90% of its total assets to equity securities, including common stocks, American Depositary Receipts (ADRs), and Global Depositary Receipts (GDRs), issued by US exchange-listed companies. These companies are identified by the index as crucial to the water industry, specializing in products and services for water conservation and purification across residential, commercial, and industrial sectors. Both the fund and its underlying index are rebalanced quarterly and undergo an annual reconstitution each April. As of August 31, 2022, Morningstar awarded the fund an impressive 5-star overall rating among 106 peer funds. Its historical performance ratings included 3 stars for the three-year period (out of 106 funds), and 5 stars for both the five-year (out of 99 funds) and ten-year (out of 87 funds) periods. These Morningstar ratings, sourced from Morningstar Inc., are derived from a risk-adjusted return measure that emphasizes consistent performance and accounts for downside volatility. Funds must possess a minimum three-year history to be rated, and for comparison purposes, open-end mutual funds and exchange-traded funds are considered together. The overall rating represents a weighted average of the 3-, 5-, and 10-year metrics, where applicable, factoring in fees and expenses but excluding sales charges. It is crucial to remember that past performance does not guarantee future returns. Morningstar ratings are subject to monthly changes, and the rating would have been lower if fees had not been waived or expenses reimbursed.
