Here's a scenario that ruins a lot of earnings seasons.

You buy puts. The stock drops 8% the next morning

exactly the direction you called. And you still lose money.

That's not bad luck. It's IV crush, and you can predict it in advance.

Here's the core idea in plain words. Before earnings, nobody knows the result, so implied volatility spikes and options get expensive. That extra cost is an uncertainty tax. The moment earnings drop, the uncertainty is gone, IV collapses, and the tax gets refunded

to whoever sold you the option.

Watch it on one trade. Stock at $100, earnings tomorrow, a one-week put costs $5. That $5 encodes an expected move of about 5%. So your real breakeven is $95, not zero. If the stock only falls to $97, you were directionally right

but your put is worth about $3. You paid $5. You lost 40% being right.

The trap in one line: you weren't betting the stock would fall. You were betting it would fall more than the market already priced in.

What a disciplined trader does: check the expected move before touching an option, and ask the sharper question

not which way, but will it move more than what's priced. If you don't have an edge on that, you don't have a trade. And if you do want a position, structuring it to sell the inflated premium (defined risk) makes the crush work for you instead of against you.

This transfers past earnings, too. Fed decisions, jobs reports, drug trials

any known catalyst has already-expensive options. Same mechanism every time.
