Income concepts and terms
Yield Traps
A quoted yield you will not receive — either because the payment is about to change, or because the number was never income in the first place.
A yield trap is a security whose displayed yield is high for a reason that makes it unrepeatable. It happens two ways. The arithmetic can be stale, because the price has fallen on an expected cut while the trailing dividend still reflects the old rate. Or the distribution can be real but funded from capital, borrowings, asset sales or realised gains rather than from earnings. The term describes the gap between what a screen shows and what actually arrives.
Reference — dividends and distributions
The labels above place this income type before you read a word. The first is the mechanism — how the money actually reaches you, whether by lending it out, owning a slice of something, renting an asset, licensing a right, selling an option or owning a business somebody else runs. The second says whether the income keeps arriving on its own once it is running, or whether it needs work from you to keep coming. Both are descriptions of how the thing is built, not verdicts on it.
What the term means
Yield trap is not a technical classification with a legal definition. It is a name for a failure mode: the number displayed on a screen and the cash flow that actually arrives disagree, and the disagreement is discovered after the purchase rather than before it.
There are two distinct families. Arithmetic traps involve a yield figure that is stale or annualised from a payment that will not repeat. Funding traps involve a payment that is genuinely being made, but out of capital, borrowing, or asset sales rather than earnings.
The word trap describes the reader's inference, not anyone's intent. Most of these situations are disclosed accurately, in filings and fund notices that a yield screen simply does not read.
A high yield is not itself evidence of a trap. REITs and BDCs are structurally required or incentivized to distribute most of their income, closed-end funds routinely use leverage, and option-income funds convert volatility into cash — all of which produce structurally higher yields for reasons unrelated to distress. The reverse error exists too: a low yield can sit on a fragile payment, and a screen sorted for high yield will never surface it.
The arithmetic version
A trailing yield is calculated from dividends already paid, divided by the current price. If the price falls sharply on news the market reads as a coming cut, the trailing yield rises by itself, with no new information in the numerator at all.
A special or one-time dividend still sitting inside the trailing twelve-month window, or a single payment annualised as though it were routine, produces a yield that is scheduled to disappear. This is common among mortgage REITs, commodity-linked payers, managed-distribution funds, and many non-US companies that pay a large final dividend and a small interim one.
The stale-data problem runs in both directions. A forward yield built from a rate that has already been announced as cut, but not yet updated in a data feed, understates the coming payment rather than overstating it.
Cross-border mechanics add further noise. A foreign payer's dividend converts to dollars at the exchange rate on the payment date, and ADR custody fees are deducted before the holder sees anything, so the amount received differs from the headline yield shown on a US screen.
The funding version
Return of capital means part of a distribution is the investor's own principal being handed back. It is not income for tax purposes — it reduces cost basis and is taxed as capital gain only once basis reaches zero — yet it appears in full inside a fund's stated distribution rate.
Return of capital is not automatically destructive. It can reflect depreciation passing through a real estate vehicle, or unrealised gains being distributed ahead of realisation. It becomes destructive when a fund pays out more than it earns, in which case net asset value tends to fall by roughly the shortfall.
Leverage raises the distribution and the risk together: a fund borrowing to invest can pay more while the spread between its borrowing cost and portfolio yield is positive, and considerably less once that spread compresses. Option-income funds distribute premium and realised gains; when the underlying falls, upside stays capped by the calls written, and maintaining the distribution can require paying out capital instead of income.
An operating company can fund a dividend from new debt or asset sales for several quarters — legal, visible in the cash-flow statement, and not repeatable. Book-value businesses such as mortgage REITs can distribute cash while book value erodes underneath, so a holder collects income and loses principal in the same period.
How the gap is spotted
The distribution is checked against the earnings measure that fits the vehicle: payout ratio against earnings for an operating company, FFO or AFFO coverage for a REIT, net investment income coverage for a BDC, distributable cash flow coverage for an MLP.
The cash-flow statement matters more than the income statement here. Dividends paid are set against operating cash flow, new borrowing, and proceeds from asset sales to see what is actually financing the payment.
For funds, the distribution rate is compared with the SEC 30-day yield, and the distribution is compared with NAV total return over several years. A NAV that declines by roughly the amount distributed is the signature of a fund paying itself out rather than earning its payment.
Closed-end funds issue Section 19a notices when a distribution includes estimated return of capital, and Form 1099-DIV settles the actual composition after year end. The payment history is checked for the pattern the yield implies — regular, variable, or one-off — and the date on the quoted number itself is checked, since stale quotes and unrevised dividend records account for most of the extreme yields on any screen.
Where you will meet it on this site
Every yield-ranked table on this site carries a reminder that it is a research screen, not a ranking of quality, and that sorting purely on yield concentrates the securities where the market has priced in the most doubt.
The research score used elsewhere blends yield with payout, coverage, and payment history precisely so that the top of a table is not simply a list of the highest yields.
Fund and covered-call reference pages separate the stated distribution rate from earned income, and the options section explains why an option premium functions differently from interest. The dividend-cut page covers what happens when the market's expectation about a coming reduction turns out to be right.
No page on this site labels a specific security a trap. The pages describe the mechanics so a reader can check the arithmetic and the filings independently.
What to remember
- A yield trap is a mismatch between a displayed yield and the cash flow that will actually arrive, not a formal classification.
- Arithmetic traps come from stale or annualised numbers, often after a price drop or a one-off payment; funding traps come from real payments financed by capital, debt, or asset sales rather than earnings.
- Return of capital is not taxed as income — it lowers cost basis and defers tax until basis is exhausted or the position is sold.
- A high yield alone is not evidence of a trap; REIT payout rules, fund leverage, and option-income strategies all produce structurally elevated yields for non-distressed reasons.
- Checking coverage ratios, cash-flow statements, Section 19a notices, and NAV trends against the distribution rate is how the gap gets found before the payment does.
- The reverse trap exists too — a low, unremarkable yield can sit on an unstable payment that a high-yield screen will never surface.
This page explains how the income type works, which does not change from week to week, so it deliberately carries no rate and no price. The links below go to the pages that hold the current figures for it, each one stamped with the date the data was pulled. Read the mechanism here first: the numbers there are far easier to judge once you know what they are measuring.
