Invesco California AMT-Free Municipal Bond ETF (PWZ) is an exchange-traded fund that seeks investment results corresponding to the ICE BofA California Long-Term Core Plus Municipal Securities Index, generally investing at least 80% of its total assets in investment-grade, tax-exempt municipal securities issued by the State of California or its political subdivisions, or by U.S. territories such as Puerto Rico and Guam; these securities feature at least 15 years remaining to final maturity, are exempt from federal alternative minimum tax (AMT), and are capitalization-weighted based on amounts outstanding, with the fund and index rebalanced and reconstituted monthly. The ETF provides exposure to long-term municipal bonds, primarily in sectors like education, health facilities, public works, and utilities, with a portfolio skewed toward maturities of 15-25 years and over (over 97% allocation), predominantly rated AA or higher by S&P and Moody's; it distributes monthly ordinary income dividends, yielding approximately 3.41%, and trades on NYSE Arca with an expense ratio of 0.28% under primary advisor Invesco Capital Management LLC and distributor Invesco Distributors, Inc. Launched on October 11, 2007, PWZ targets California-resident investors seeking federally tax-exempt income and operates within the U.S. fixed-income market, focusing on non-diversified municipal tax-exempt bonds.
Recent developments include significant net inflows of $471.49 million over the past year, contributing to assets under management reaching $1.10 billion as of late 2025, alongside a year-to-date NAV performance of -4.24% and a 1-year NAV return of -3.95%, reflecting interest rate sensitivity in long-duration holdings; the fund has maintained steady monthly distributions, such as $0.06557 per share in September 2025 and $0.06882 in April 2025. Invesco, the ETF's issuer headquartered in Atlanta, Georgia, reported record firm-wide AUM of $2.12 trillion in Q3 2025, up 18% year-over-year, driven by strong ETF and fixed-income flows, though no PWZ-specific acquisitions, partnerships, or index methodology changes were announced in the last 1-2 years; portfolio management saw minor updates with Daniel Michalak joining as co-manager effective March 1, 2025.
