A trader nailed the earnings direction. The stock gapped up the next morning, and the position was still down 40%.

Right on the company. Wrong on the trade. Let me walk the mechanism, because the numbers are the whole lesson.

Stock at $120. Earnings after the close. The day before, the trader buys ten at-the-money 120 calls at $6.20 — $6,200 riding on one overnight print.

Here's what most people miss: those weekly options were carrying implied volatility near 90%. Ahead of a binary event, dealers inflate vol because nobody knows the outcome. That vol priced an expected move of about 8% — roughly plus or minus $10.

So the $6.20 call is pure air. Zero intrinsic value. Every penny is extrinsic, built from time and volatility. The bar to profit isn't zero — it's the whole expected move.

Then the report drops. The uncertainty evaporates. Implied vol collapses from 90% toward 40%. That's IV crush, and it deletes premium through vega the instant the market opens — regardless of direction.

The company beats. Stock gaps up 3% to $123.60. The trader was right. But 3% is way short of the 8% they paid for. The call is now worth about $3.70. Entry $6.20, exit $3.70. A 40% loss on a correct call.

The one line to remember: when you buy an ATM call into earnings, you're not long the stock — you're long volatility, at the most expensive moment of the quarter, right before the one event guaranteed to make it cheaper.

What a disciplined trader does: before buying premium into any scheduled event, find the expected move first. That's your real breakeven, not the strike. Then ask what happens to your vega when the event passes. If the answer is "it gets crushed," you either want a structure that sells vol against you, or you don't want the trade.

This is educational commentary, not personalized financial advice — every number here is a worked example.
