Covered calls before earnings: what the gap does to you

A covered call that spans an earnings report pays more because the stock can gap overnight. If it gaps down, the bigger premium covers only a small part of the drop. If it gaps up, you're capped. Many sellers use one rule: no earnings inside the trade.

Why the premium is bigger

Before an earnings report, the market knows a big move could come overnight. It just doesn't know which way. Option buyers pay more for that chance. It shows up as higher Implied volatility on every date that includes the report.

So a call that spans earnings pays more than one that doesn't. That extra isn't a gift. It's the price of carrying a gap you can't control.

The gap down, worked out (an illustration, not a trade idea)

You own 100 shares of a made-up stock, XYZ, bought at $50. Earnings come out in 10 days. You sell a 30-day $55 call that spans the report. It's bid $2.00, about twice what a quiet month would pay. You collect $200.

Day 10, after the close: XYZ reports. Sales missed, and the company cut its forecast.

Day 11, the open: XYZ opens at $40. It never trades between $50 and $40. There was no price in between to sell at.

Your position that morning:

• Shares: $4,000, down −$1,000.
• The call: worth about $0.05 now. You collected $2.00, so it's +$195 on paper.
• Total: −$805.

Day 30, expiry: XYZ is still near $40. The call expires worthless. You keep the $200.

The $200 premium covered $2 of a $10 drop. The other $8 a share is yours.

The gap up isn't a free win either

Look at the last row. A plain holder at $65 is up $1,500. You're up $700, because your shares go at $55.

If you want to keep the shares after a jump, you'd have to buy the call back. At $65, a $55 call is worth at least $10. That's $1,000 to close a call you sold for $200: −$800 on the call, against +$1,500 on the shares. Either way, the jump you were hoping for mostly went to the call buyer.

So the bigger premium buys you a small cushion on a gap down, and costs you most of a gap up.

The honest view of the risk

Part of this risk comes from the shares, not the call. If you hold XYZ through the report, a gap down hurts with or without a call sold.

What the call changes is the shape:

• Gap down: you take nearly the full drop, minus the premium.
• Gap up: you give up most of the jump.
• Dull report: you keep a bigger premium than usual.

That's a trade that wins most when nothing happens, and loses its upside when something good happens. Earnings are the moment something is most likely to happen.

The rule: no earnings inside the trade

Many careful sellers keep one simple rule: the report must fall after the expiry date. If it doesn't, they either:

1. Pick an earlier expiry that ends before the report, or
2. Sell no call this month, and sell one right after the report instead. See selling a covered call right after earnings.

Then, as a separate choice, they decide whether to hold the shares through the report at all. That's a stock decision, not an options one.

The same rule applies to the put side of the wheel strategy. A put that spans earnings can be assigned on a gap down, far below the strike.

How to check the earnings date

• Look on the company's investor relations page. Confirmed dates are posted there, often a few weeks ahead.
• Treat broker dates with care. Some show an estimate until the company confirms. Look for "confirmed" or "estimated."
• Check every time you sell. Dates can move by a week or more from one quarter to the next.
• Watch the option prices. If one expiry date pays far more than the one before it, earnings may sit between them.

See checking the earnings date before selling for the full routine.

If you already sold a call over earnings

You don't have to panic. Options:

• Leave it. Decide in advance what you'll do with the shares if the stock gaps down. Write it down tonight.
• Buy it back before the report. It will cost more than a quiet call, because the earnings risk is priced in. The cost is known; the gap isn't.
• Sell the shares and close the call together, if you wouldn't hold XYZ through the report anyway.

What not to do: sell more calls to "collect more" before the report. That makes the cap bigger without touching the downside.
