First, what you're actually buying
A preferred share is a hybrid. It pays a fixed dividend like a bond, but it sits below a company's debt and above its common stock in the capital stack — so in a bankruptcy, preferred holders get paid after bondholders but before common shareholders. They're issued mostly by banks, insurers, REITs, and pipeline companies that need capital but don't want to issue more common stock.
The key trait: because the payment is fixed, the price moves on interest rates. When rates rise, a fixed payment is worth less, so the price falls — the same math that moves bonds. Preferreds are also typically perpetual, meaning no maturity date, which makes them extremely sensitive to rate moves.
PFFA — the Virtus InfraCap U.S. Preferred Stock ETF — is an actively managed fund that buys these preferreds and adds leverage to boost the income. It launched on May 15, 2018.
The hook, and the question
PFFA pays roughly a 10% yield, monthly, and trades at $20.51 — near the bottom of its 52-week range of $20.23 to $22.50. The pitch right now is simple: it's on sale after the pullback.
Here's the tension the numbers raise. On September 16, 2026, the Federal Reserve raised its target range a quarter point, from 3.50%–3.75% to 3.75%–4.00%, on a unanimous 12-0 vote — the first increase since July 2023. Its own projections go further than the hike itself: the median participant now sees 4.1% at the end of 2026 and 4.1% again at the end of 2027 — another quarter point from here, and then no cuts for two years. Preferreds and leverage are both rate-sensitive. So the question worth answering is whether that 10% is durable income, or leverage arriving at an awkward moment. Let's work it in order.
1. The income, in real numbers
The latest declared distribution is $0.1725 per share, paid monthly (declared 2026-08-20). At the current price that's an annualized run-rate of about 10.09%. Over the trailing twelve months the fund paid $2.06 per share, a TTM distribution yield of 10.04%. The issuer's 30-day SEC yield, a more standardized measure, is 8.78% as of 8/31/2026 — down from 9.71% at 6/30/2026. Hold onto that gap: the standardized yield is falling while the headline distribution rate stays above 10%.
Distributions are variable going forward — these are the latest actuals, not a guarantee. The fund's 19a notices break down how much of each distribution is income versus return of capital. For the August 2026 distribution, Virtus estimated $0.1492 per share as net investment income and $0.0233 as return of capital — 13.5% of the payout. (The notice prints dollars; the percentage is ours.)
Then it gets interesting, in two ways. First, that estimate doubled. The notices for November 2025, December 2025 and January 2026 each put return of capital at 6.75% of the payout — roughly $0.0115 a month. Beginning with the February 2026 notice it jumped to 13.5%, or $0.0233, and it has sat at exactly that figure for seven consecutive months. The fund's own estimate of how much of the distribution is the holder's capital coming back doubled in February and hasn't come down since.
Second, the audited books don't agree with it. Across the six distributions from November 2025 through April 2026, the notices estimated $0.1045 per share of cumulative return of capital — 10.15% of the $1.03 actually paid. The fund's semiannual report covering that same six-month window books the entire $1.03 to net investment income and reports return of capital of $0.00. The estimate and the audited statement flatly disagree, and the estimate is the less flattering of the two. That gap is the cleanest illustration available of why a 19a notice states on its face that it is an estimate and not a tax figure: the notice opens the question, the financial statements close it. For the last completed fiscal year, ended 10/31/2025, the audited return of capital was $0.23 per share — about 11% of distributions.
Performance and yield figures are historical and may change. Total return includes price movement and distributions where available. Past performance does not guarantee future results. Yield is not the same as total return.
2. Why the price is so sensitive — the mechanism
Three forces stack up in a hiking cycle, and they're the spine of understanding this fund.
Perpetual duration. Because most preferreds never mature, they behave like a bond with effectively unlimited duration — one of the most rate-sensitive instruments an income investor can hold. When rates rise, the price of the underlying holdings falls.
