Morris notes that the last time PCEF's underlying index yielded north of 10% was in April 2020 – the midst of the coronavirus bear market. Translation: PCEF is rate-sensitive, indicating that if inflation cools and the Federal Reserve can relent on rate hikes or, at the very least, scale back its aggressive posture, the Invesco fund could benefit. On that note, some closed-end funds and the Invesco CEF Income Composite ETF (NYSEARCA: PCEF) could be worth considering by income investors today.
