Dividend & Income ETF Glossary
Plain-English definitions of the terms income investors actually run into — no jargon explained with more jargon.
0DTE (Zero Days to Expiration)
Options that expire the same day they’re traded. Funds like QDTE and XDTE sell 0DTE calls each morning to harvest premium, enabling weekly distributions while retaining overnight and gap-up exposure that traditional monthly covered calls give away.
Annualized Return (CAGR)
The constant yearly growth rate that would turn your starting value into your ending value over the period measured. A fund that doubled in 5 years has a CAGR of about 14.9% — not 20% — because compounding does part of the work. It makes returns over different time spans comparable.
Covered Call
An options strategy where a fund owns a stock (or index exposure) and sells call options against it, collecting premium income in exchange for giving up gains above the strike price. This is the engine behind most high-yield income ETFs: steady income, capped upside, and full exposure to declines.
Declaration Date
The day a fund officially announces an upcoming distribution — the amount, ex-dividend date, record date, and payment date. Until declaration, any future distribution is an estimate. Our dividend calendar marks officially declared distributions with an “Announced” badge.
Distribution
A cash payment from a fund to its shareholders. For income ETFs the payment can include dividends, option premium income, interest, capital gains, and return of capital, which is why it’s called a “distribution” rather than a “dividend.”
Distribution Rate
The most recent distribution annualized and divided by the current price — the headline number fund marketing quotes. It reflects what the fund paid recently, not what it will pay. For funds with variable payouts, the rate can change dramatically month to month.
DRIP (Dividend Reinvestment)
Automatically using each cash distribution to buy more shares of the same fund. Reinvesting compounds your share count over time and is the standard assumption behind total return calculations. Try it with our total return calculator.
Ex-Dividend Date (Ex-Date)
The first day a stock or ETF trades without the right to the upcoming distribution. You must own shares before the ex-date to receive the payment. The price typically drops by roughly the distribution amount on the ex-date — you don’t get free money by buying the day before.
Expense Ratio
The annual fee a fund charges, expressed as a percentage of assets. A 0.99% expense ratio costs $99 per year on a $10,000 position. It’s deducted from fund assets continuously — you never see a bill, but it quietly reduces your return every year.
Forward Yield
An estimate of the next 12 months of income: recent per-share distributions annualized by payout frequency, divided by the current price. More responsive than trailing yield when payouts are rising or falling — which for option income funds is most of the time. See our methodology for exactly how we compute it.
Fund of Funds
An ETF that holds other ETFs instead of individual securities. YMAX, for example, holds a basket of YieldMax single-stock funds — spreading single-stock risk across many underlyings while layering a second set of fees on top.
House Money / Breakeven
The point at which cumulative distributions received equal your original investment — after that, further payments are “house money” on your cost basis. A popular mental model for high-yield funds, though it ignores what the share price did in the meantime. Every fund page on this site includes a house money calculator.
Payment Date (Pay Date)
The day the distribution cash actually lands in your brokerage account, typically a few business days after the ex-dividend date. Upcoming pay dates are listed on our dividend calendar.
Price Return
The change in share price alone, ignoring all distributions. For high-yield funds, price return and total return can point in opposite directions: a fund can be down 30% on price while up on total return because of the income it paid along the way.
Record Date
The date a fund checks its shareholder list to determine who receives the distribution. With T+1 settlement it falls one business day after the ex-date. Practically, the ex-date is the one investors need to watch.
Return of Capital (ROC)
The portion of a distribution classified as giving you your own investment back rather than income. ROC isn’t taxed when received — it reduces your cost basis instead, deferring tax until you sell. Common and often deliberate in option income ETFs; the exact split arrives on your year-end 1099-DIV.
Reverse Split
A share consolidation (e.g. 1-for-5) that raises the share price without changing the value of your position. Common among high-yield funds whose prices have eroded. Historical charts must adjust for splits or the price history looks wildly wrong — ours do; see methodology.
Synthetic Covered Call
A covered call built entirely with options: the fund creates stock-like exposure using a bought call and a sold put, then sells calls against that synthetic position. YieldMax funds use this structure — they never own the underlying stock, which is also why they don’t receive its dividends.
Total Return
The complete return of an investment: price change plus all distributions, usually assuming reinvestment. The single most honest way to compare income funds against each other or against simply holding an index fund. Compare any two funds with our comparison tool.
Trailing (TTM) Yield
The sum of the last 12 months of distributions divided by the current price. It’s backward-looking and verifiable, but slow to reflect payout changes — a fund that just cut its distribution still shows a fat trailing yield for months.
Underlying (Asset)
The stock, index, or asset an option income fund builds its strategy around. MSTY’s underlying is MicroStrategy (MSTR); QDTE’s is the Nasdaq-100. The underlying’s price path and volatility drive nearly everything about the fund’s results.
Yield on Cost
Annual income divided by what you originally paid rather than the current price. Useful for tracking your own position over time, but not comparable across investors or funds — everyone’s cost basis is different.
Yield Trap
An investment whose high headline yield masks deteriorating fundamentals or an unsustainable payout — the income arrives, but price losses exceed it. The defense is checking total return against a benchmark, which every fund page on this site shows.
Put the vocabulary to work
The best way to understand these concepts is to see them applied to real funds with real numbers.
