The Theta Gang

You sell premium. Patient. Boring. Mostly profitable — right up until earnings week, when you forget IV exists and lose three months of gains in two days. You'll do this again. You always do.

Premium selling works. Implied vol systematically overprices realised vol, and harvesting that overpricing through structured positions is a legitimate, proven strategy. You understand the mechanics. The equity curve on your short-premium book is a beautiful grind — small, consistent, reliable. Month after month of theta decay into your account.

Then earnings season comes. You look at a name with elevated IV. Run the straddle numbers. Premium is irresistible. What you're not running hard enough — never quite hard enough — is the scenario where the stock gaps hard on the print. You know this scenario exists. The market is pricing it. That pricing is exactly why the premium is elevated. You sell it anyway.

Mechanism is experiential overconfidence. You've seen hundreds of earnings prints, most didn't move as much as the straddle implied. True. IV overprices realised vol on average. But "on average" conceals the tail. A margin miss that puts the stock down double- digits. A surprise beat that puts it up double-digits. The tail is fat, and you've convinced yourself through repetition it won't visit you this time. You made this note last year. You'll make it again.

Days before a high-beta name reports. IV elevated. You've been selling premium all month — index iron condors, put spreads. Clean. Boring. Profitable.

Pull up the earnings name. Straddle pricing a big move. You've been doing this for years. The stock often doesn't move as much as implied. Sell iron condors, wings wider than usual. Collect a fat premium.

The report drops. Revenue beats, margin misses, or the other way around. Some headline twist. Stock gaps through your wings. Close the iron condors for a brutal loss. Weeks of premium, gone in one trade.

Open the journal. Write: "No more selling around earnings on this name." Scroll up. You wrote the same sentence last cycle.

Build a no-fly list. Any underlying with earnings within 14 days is off the short-premium menu. Full stop. Not a soft guideline — a hard rule, written in your trading rules doc, enforced before you pull up the option chain. You can hold positions already on through earnings. No new short-premium positions in the window.

If you can't blacklist earnings entirely, mandatory 75% size reduction on any new position within 14 days of a scheduled event. The full-size earnings trade that wipes out six weeks of gains is a single-point failure mode. You've identified it. You've journaled about it. Now you need a structural rule that makes overriding impossible in the moment, because you've demonstrated repeatedly that you will override it. Premium will always look irresistible. Make it irrelevant by removing the option.
