It is the most confusing loss in options: you predict the earnings direction correctly, the stock moves your way — and your option is worth less than you paid. The culprit is usually IV crush, the collapse of implied volatility the moment uncertainty resolves. Understand it once, and a whole class of expensive mistakes disappears.
An option's price has two ingredients: intrinsic value (what it would be worth if exercised now) and time value (everything else). Implied volatility, or IV, is the market's priced-in expectation of how much the stock will move — and it feeds directly into time value. High IV means expensive options; low IV means cheap ones. IV is not a prediction of direction. It is a price on uncertainty itself.
Before an earnings announcement, nobody knows the result — but everybody knows a big move is possible. Market makers raise IV to compensate for that jump risk, so options expiring just after earnings get expensive. A call that normally costs $2.00 might cost $4.50 in earnings week, even with the stock sitting still. You are paying for the event, not just the direction.
The moment earnings print, the uncertainty is gone. IV collapses — often by 30–50% overnight — and with it the time value of every option on that stock. This is the crush. It hits buyers of premium hardest and benefits sellers, who sold the inflated uncertainty and buy it back cheaper.
Illustrative numbers: a stock trades at $100. A week before earnings you buy a $105 call expiring just after the announcement for $5.00 ($500 per contract). Earnings beat expectations and the stock rises to $103 — your direction was right. But IV crushes from a high pre-earnings level to a normal one, and your call is now worth $3.50. You were right about the company and still lost $150. The stock needed to rise past roughly $110 — the strike plus the inflated premium — just to break even. The market had already priced in a move; your move had to beat the priced-in move.
The lesson generalizes: every option price already contains the market's guess about the future. Your edge has to beat the guess, not just the direction.

Yes. Crush is about volatility, not direction — it deflates the time value of all options on the stock, calls and puts alike, once the event passes.
Rarely and only if the stock's move is so large it overwhelms the volatility collapse. That is exactly what the inflated premium was pricing in, so it takes an exceptional move.
Most brokers and chains show IV per option. Compare it with the stock's usual IV: a big gap before an event date is the market charging for the announcement.
No. Crush follows the resolution of uncertainty. If the announcement creates new uncertainty — a surprise warning, a guidance cut — IV can stay high or even rise. Crush is the usual case, not a law.
