Here's a painful rite of passage: a company beats earnings, the stock jumps — and your call options lose money anyway. You were right about the direction and still got paid nothing. This isn't bad luck. It's mechanics. It's called IV crush, and understanding it will save you more money than almost any other single lesson here.
Key terms
| Term | Plain-English meaning |
|---|---|
| Implied volatility (IV) | How big a move the options market expects, baked into option prices. High IV = expensive options. |
| IV crush | The collapse in IV right after a known event (like earnings) passes. Options get cheaper instantly, even if the stock moves. |
| Binary event | A scheduled moment with two-ish outcomes — earnings, FDA decisions, court rulings. The market knows when, just not which way. |
| Straddle | Buying a call and a put at the same strike — a bet that the stock will move a lot, without picking a direction. |
| Time value | The part of an option's price above its intrinsic value — basically, what you're paying for time and uncertainty. IV crush eats this part. |
Why options get expensive before earnings
An option's price has two ingredients: intrinsic value (what it'd pay if used now) and time value (payment for uncertainty). Before earnings, uncertainty is at its peak — the stock could gap 8% either way overnight. Nobody knows, so the market charges extra for that uncertainty. IV rises, and with it, every option on the chain gets more expensive.
Think of it like hurricane insurance: the policy costs the most the day before landfall, when nobody knows where it hits. The morning after, when the path is known, the price collapses — even if your house is fine.
Worked example: right on direction, wrong on the trade
Illustrative numbers, rounded for clarity. A stock trades at $35 the day before earnings. The options market implies about an 8% move — roughly $2.80 either way. An at-the-money straddle (the $35 call + the $35 put) costs about $2.80, or $280 per straddle.
You buy one straddle for $280, betting on a big move. Earnings land:
- The company beats. The stock jumps 5% to $36.75. You called the direction right!
- But the uncertainty is gone, so IV crushes. The $35 call now has $1.75 of intrinsic value ($36.75 − $35) plus a sliver of time value; the $35 put is nearly worthless. The straddle is worth about $1.90 → $190.
- You paid $280 for something now worth $190. Loss: $90 — on a trade where you were right.
The 5% jump wasn't enough to overcome the $2.80 of expected-move premium you'd paid for. The market had already priced in a bigger swing than the one that happened. This is the trap: you don't just need the stock to move — you need it to move more than everyone already expected.
The standing rule on this account
This is why the account runs a hard rule: no new option entries immediately before earnings. Buying premium into a binary event means paying peak IV and then watching it evaporate the next morning. Shares are a different story — a stock doesn't have IV to crush — but options bought the day before a print are, more often than not, just a donation to the sellers.
The flip side is opportunity after the event: once IV has crushed, options are cheap again — and now you can trade the actual reaction instead of the expected one.
Common mistakes
- Confusing "good earnings" with "good option trade." A beat can still produce a smaller move than the options priced in. The stock and the option are two different bets.
- Buying weeklies into the print. Short-dated options carry the most IV inflation relative to their price — they're where crush hurts most.
- Holding a winner into earnings "to see what happens." If you're up on a position and earnings are tomorrow, that profit is partly inflated IV. Consider whether you'd still like the trade at post-crush prices.
- Assuming high IV means "everyone's bullish." High IV means everyone expects a big move — direction unknown. It's fear and greed in both directions.
The takeaway
Before a binary event, you're not just betting on direction — you're betting against the market's expected move, with inflated prices working against you. After the event, IV crushes and the game resets. Respect the crush: don't buy premium into the storm.
