Covered Calls: The Complete Guide

What is a covered call?

A covered call is long 100 shares of a stock plus short 1 call on the same stock. The shares cover the call: if it is exercised you deliver stock you already own rather than buying it in the market, so the obligation is fully collateralized and carries no margin requirement of its own.

OCC's Characteristics and Risks of Standardized Options states the trade-off: the covered call writer "forgoes the opportunity to benefit from an increase in the value of the underlying security above the option's exercise price but continues to bear the risk of a decline in the value of the underlying security." You are paid a premium to give up the tail of the upside and keep the tail of the downside.

Covered call example: the full math

Round numbers, no commissions, 30 days to expiration. Every figure here is illustrative, not a quote on a real ticker.

• Entry: buy 100 shares at $50.00 = $5,000.00 debit.
• Call sold: 1 contract, $50 strike, $1.60 premium = $160.00 credit.
• Net cash out: $5,000.00 − $160.00 = $4,840.00.

Max profit = (strike − purchase price + premium) × 100 = ($50.00 − $50.00 + $1.60) × 100 = $160 at any price at or above $50.00.
Breakeven = $50.00 − $1.60 = $48.40. Max loss = ($50.00 − $1.60) × 100 = $4,840 if the stock goes to zero.
Annualized return = ($160 ÷ $5,000) × (365 ÷ 30) = 3.2% × 12.17 = 38.9% — the same whether the call expires or is assigned, because at a $50 strike the max profit equals the premium. It assumes you repeat the trade at a similar premium every month, so read it as a rate on one 30-day trade, not a forecast.

What the position pays at expiration:

• Stock at $60.00 (called away): +$160. The shares alone would have made $1,000; the $840 gap is the cost of the call.
• Stock at $52.00: +$160 — the cap is real.
• Stock at $48.40: $0. The premium has been spent cushioning the decline.
• Stock at $45.00: ($45.00 − $50.00 + $1.60) × 100 = −$340; at $40.00, −$840.

Run your own numbers first. The covered call calculator returns max profit, breakeven and annualized yield; the options simulator charts the position across expiration prices. To find the trade in the first place, start with how to screen for covered calls.

Covered call vs cash-secured put vs covered put — don't confuse them

• Covered call — long 100 shares + short call. Bullish to neutral. Needs the shares. Max profit capped at strike plus premium; max loss is the share cost less premium.
• Cash-secured put — cash collateral + short put. Bullish to neutral. Needs the cash. Max profit is the premium alone; max loss is the strike less the premium per share. Same payoff shape, entered from the cash side. See the cash-secured put calculator.
• Covered put — short 100 shares + short put. Bearish to neutral. Needs margin and short-sale permission, is barred in an IRA, and carries uncapped upside risk on the short stock leg. A different trade despite the word "covered."

The first two differ only in what you already hold: shares make the call the income trade, cash makes the put the income trade, and alternating them is the wheel strategy. The distinctions line by line are in covered call vs cash-secured put and covered put vs covered call.

Choosing the strike and expiration

The trade-off moves one way: the further out of the money the call, the less premium and the more upside you keep. OIC frames the choice as which strike "represents an acceptable liquidation price" — strike plus premium is your effective selling price if assigned, so start there. A call with 30 days or less to expiration, or one deep in the money, is not a qualified covered call for tax purposes. See choosing a strike above or below the current price.

Assignment: what happens when the call is in the money

Standardized US equity options are American-style, so the holder can exercise any business day. OCC assigns that notice at random among clearing members short the series — you learn after the fact. Assignment is usually the plan working: the shares leave at the strike and you keep the premium. Two cases catch people out. The day before an ex-dividend date, an in-the-money call with little time value is a cheap way to capture the dividend — and you owe the dividend along with the shares. At expiration, exercise-by-exception covers equity options $0.01 or more in the money, so "barely above my strike" is still an assignment. To keep the shares you must buy the call back before the notice arrives: see what happens when a covered call is in the money, covered call assignment, and what happens when a covered call expires. OIC's historical figures put more than 72% of contracts closing before expiration, about 22% expiring without value, and roughly 6% exercised.

Risk: what the premium does not cover

• Downside stock risk, essentially intact. $1.60 of premium protects the first 3.2% of a decline from $50. The rest is yours.
• Capped upside. A stock at $65 earns you $160 where ownership earned $1,500. Covered calls lag buy-and-hold in strong rallies by construction.
• Concentration. Long the shares and short volatility on the same name, so a gap down hits both legs at once.
• The shares are locked. Selling them with the call open leaves a naked short call with uncapped risk.

Good fit: you own the shares, would accept strike plus premium as an exit, and are flat to moderately bullish over 30–45 days. Bad fit: you expect a large move up, or it is a low-basis long-term holding in a taxable account.

Margin, account type, and the IRA question

Cboe's strategy-based margin schedule lists "short call and long underlying" with no requirement on the short call, 50% initial and 25% maintenance on the long stock, valued at the lower of market value or the call's aggregate exercise price. FINRA Rule 4210 reaches the same result at (f)(2)(I)(i).

In a cash account you pay for the shares in full. Fidelity lists covered calls among the strategies available in a cash account and an IRA; Schwab puts covered calls and cash-secured equity puts in its Level 0 tier, open to IRAs without margin. Short stock and naked calls need borrowing, which IRAs cannot do.

Taxes: the qualified covered call rules

IRS Publication 550 says to carry the premium in a deferred account until the obligation expires, the stock is sold on exercise, or the position is closed. If the call expires worthless the premium is a short-term capital gain; if assigned, it is added to the amount realized on the share sale and the character follows your holding period.

The qualified covered call exception is why covered calls usually escape the straddle loss-deferral rules: per Publication 550 the call must be exchange-traded, granted more than 30 days before expiration and within 12 months of it, not deep in the money, not written by an options dealer, and produce capital gain or loss. An in-the-money qualified call suspends your holding period while it is open; one that fails any test, such as a weekly with 21 days to expiration, falls back into the straddle rules. Not tax advice.
