Covered Call ETF Glossary

A

Assets Under Management AUM

The total market value of all the assets a fund holds on behalf of its investors. Larger AUM often means tighter trading spreads and better liquidity, but size alone tells you nothing about a fund's strategy or quality.

At-the-Money ATM

Describes an option whose strike price is roughly equal to the current price of the underlying. A fund that writes at-the-money calls collects large premiums but caps almost all of its upside. See moneyness.

B

Buy-Write

The combined action of buying a security (or basket) and simultaneously writing — selling — a call option against it. It's the core trade a covered call ETF automates, which is why "buy-write" and "covered call" are often used interchangeably.

C

Call Option

A contract giving its buyer the right, but not the obligation, to buy an asset at a set strike price before a set expiry date. A covered call ETF earns income by selling call options to other investors.

Capital Gain / Capital Loss

The profit (gain) or shortfall (loss) from selling an investment for more or less than you paid. Capital gains are separate from distributions — a fund can pay high distributions while its unit price, and therefore your capital gain, moves independently.

Covered Call

A conservative options strategy: you own an asset and sell a call option against it, collecting a premium. It's "covered" because you already hold the shares you might have to deliver, which limits the risk. See the full guide.

Covered Call ETF

An exchange-traded fund that holds a portfolio of securities and systematically sells call options against them, passing the option premiums (plus any dividends) to investors as regular distributions. It packages the covered call strategy into a single tradable fund. Browse current funds in the directory.

Coverage Ratio

The portion of a fund's portfolio on which it writes call options — sometimes called the overwriting level. Higher coverage means more premium income and a tighter upside cap; lower coverage keeps more growth potential.

D

Distribution

A payment a fund makes to its unitholders, usually in cash. For covered call ETFs, distributions combine option premiums, dividends from the underlying holdings, and sometimes return of capital.

Distribution Frequency

How often a fund pays distributions — most covered call ETFs pay monthly, though some pay quarterly. Frequency doesn't change the total amount paid over a year; a monthly payer and a quarterly payer can deliver the same annual total.

Distribution Yield

A fund's most recent distribution, annualized at its payout frequency and divided by its current unit price, shown as a percentage. It reflects the fund's current payout rate and is not a promise of future payments, which can change at any time. It also differs from a dividend yield because it includes option premiums, not just dividends.

Dividend

A share of a company's profits paid to its shareholders. Dividends from a fund's underlying holdings are one of the sources of the cash a covered call ETF distributes.

Dividend Yield

A company's or fund's annual dividends divided by its price. For covered call ETFs, the headline figure is usually the distribution yield, which is larger because it also includes premium income.

E

ETF Exchange-Traded Fund

A pooled investment fund that trades on a stock exchange like a single share. ETFs typically follow a strategy or index and can be bought and sold throughout the trading day at market prices.

Ex-Distribution Date

The cut-off date that determines who receives a fund's upcoming distribution. To be paid, you generally must own the fund before its ex-distribution date; buy on or after it and the seller receives that distribution instead.

Expiry Expiration

The date an option contract ceases to exist. Covered call ETFs typically write short-dated options and repeat the process as each batch expires — a continual cycle known as rolling — to keep generating premiums.

I

Implied Volatility

The market's expectation of how much an asset's price will move, embedded in its option prices. Higher implied volatility means richer option premiums — which is why funds written on volatile assets can advertise higher yields, alongside higher risk.

In-the-Money ITM

Describes a call option whose strike price is below the current price of the underlying, meaning it already has intrinsic value. See moneyness.

M

Management Expense Ratio MER

The annual percentage of a fund's assets consumed by management and operating costs. Covered call ETFs usually carry higher MERs than plain index funds because active option writing costs more to run, and the fee is deducted before you receive any distributions.

Moneyness

A description of an option's strike price relative to the current price of the underlying — in-the-money, at-the-money, or out-of-the-money. The moneyness a fund targets shapes its trade-off between income and upside.

N

Net Asset Value NAV

The per-unit value of a fund's holdings, calculated as total assets minus liabilities, divided by the number of units outstanding. Persistent return of capital in excess of what a fund earns can erode NAV over time.

O

Option Premium

The cash a call buyer pays the seller for the option. Collecting premiums is the primary way a covered call ETF generates its elevated income.

Out-of-the-Money OTM

Describes a call option whose strike price is above the current price of the underlying. Funds that write out-of-the-money calls keep more upside but collect smaller premiums. See moneyness.

P

Premium Income

The income a fund earns from selling call options, as distinct from dividends or interest. It's the ingredient that makes covered call ETF yields larger than those of ordinary dividend funds.

Price Return

The change in a fund's unit price alone, excluding distributions. Because covered call ETFs pay out so much as cash, price return understates their performance — total return is the fairer measure.

R

Return of Capital ROC

The portion of a distribution that returns your own invested money rather than income the fund earned. Modest ROC can be tax-efficient in a non-registered account, but consistently paying out more than a fund earns can shrink its asset base. Always check a fund's official tax breakdown to see how much of a distribution is ROC.

Rolling

Closing an expiring option and opening a new one with a later expiry (and often a different strike). Covered call ETFs roll their options continuously to keep the premium income flowing.

S

Strike Price

The fixed price at which a call option's holder may buy the underlying. When a fund writes a call, the strike sets the level above which its gains on those shares are capped — see upside cap.

T

Total Return

The complete measure of performance — price change plus distributions, assuming distributions are reinvested. For income funds like covered call ETFs, total return is the number that matters most, since a price return chart alone always understates them.

U

Underlying

The asset — a stock, a basket of stocks, or an index — on which an option is written or that a fund holds. A covered call ETF's risk and its income both flow from its underlying holdings.

Upside Cap

The ceiling on gains created by selling call options: above the strike price, a fund stops participating in a rally on the shares it has written calls against. The upside cap is the central trade-off of covered call investing.

V

Volatility

How much an asset's price fluctuates over time. Higher volatility raises option premiums — more income — but also signals greater risk in the underlying holdings.

Y

Yield on Cost

A distribution or dividend yield measured against the price you originally paid, rather than the current price. It shows the income return on your own cost base, and it rises if you bought before a fund's distributions grew.
