What is IV crush and how does it affect my options after earnings?

If you've ever bought an option before earnings, watched the stock move exactly the way you predicted, and still lost money — you've already met IV crush. It's one of the most disorienting experiences in options trading, and understanding it will fundamentally change how you approach earnings season as a wheel trader.

What's Actually Happening

Implied volatility (IV) is the market's expectation of how much a stock will move in the future. Before earnings, nobody knows what the numbers will look like, so options buyers bid up premiums aggressively to get exposure to that uncertainty. That demand inflates IV — sometimes dramatically.

After the announcement, the uncertainty is gone. The event happened. And the market immediately reprices options to reflect the new, calmer reality. IV collapses, often within minutes of the open. That collapse is IV crush.

Think of it like a balloon. Before earnings, everyone's blowing air into it. The moment the report drops, someone pops it. The stock might move, but the balloon is still deflated.

A Real Example With Numbers

Let's say NVDA is trading at $900 heading into earnings. The at-the-money $900 call expiring in 3 days is priced at $45. That's not because anyone thinks NVDA moves $45 in a normal week — it's because IV is running at something like 120% ahead of the print.

NVDA reports. Revenue beats estimates. Stock gaps up to $930. You were right on direction. But that $900 call you paid $45 for? It might be worth $35 now. You made $30 on the intrinsic value (the stock moved $30 in your favor), but you lost $40 on the vega — the portion of the option's price tied to implied volatility. Net result: you're down $10 on a correct directional call.

That's IV crush doing its thing. The vega exposure destroyed your profit even though your thesis was right.

Why This Matters Specifically for Wheel Traders

Here's where it gets interesting for us. As sellers of options — through cash-secured puts and covered calls — IV crush is actually your friend if you position it correctly.

When you sell a cash-secured put on a stock before earnings, you're collecting that inflated premium. If IV is at 90% when you sell and drops to 40% after the announcement, the extrinsic value of your option evaporates fast. That's profit for you as the seller, even if the stock barely moves.

Some wheel traders deliberately sell puts the day before earnings to capture this premium spike. Say you sell a 30-delta put on AAPL at a $165 strike when AAPL is trading at $180, collecting $4.50 in premium. AAPL reports, stock stays flat at $180, but IV crushes from 85% to 35%. Your put might now be worth $1.20. You can buy it back for a quick $3.30 profit, in 24 hours.

That sounds great. And sometimes it is. But there's a real risk sitting underneath this.

The Risk You Can't Ignore

IV crush only saves you if the stock doesn't move far enough to overwhelm the premium you collected. If AAPL drops to $158 after earnings, your $165 put is deep in the money. IV crush doesn't matter anymore — you're assigned shares at a price significantly above market value, and now you're stuck running covered calls from a bad cost basis.

This is the core tension with earnings plays in the wheel. You're getting paid more premium than usual, but you're also accepting more uncertainty than usual. The elevated IV exists for a reason — the market is pricing in real risk of a large move.

My personal approach: I don't sell options directly into earnings unless I genuinely want to own the stock at that strike. AAPL at $165 as an assignment price? I can live with that. I'll own it, sell covered calls, and work my way out. But I wouldn't do this with a stock I'm not comfortable holding long-term, just to chase a premium spike.

How to Spot High IV Before You Trade

You want to check IV Rank (IVR) or IV Percentile before any earnings trade. Both metrics tell you where current IV sits relative to its historical range. An IVR of 80 means IV is higher than it's been 80% of the time over the past year. That's a meaningful signal that premium is elevated and crush is likely after the event.

Most brokers show this. On tastytrade, it's right on the quote screen. On thinkorswim, you can pull up the IV Percentile column in your watchlist. If you're not already checking this before every trade, start today.

The Practical Takeaway

Before your next earnings-adjacent trade, pull up the IV Rank on whatever ticker you're considering. If IVR is above 70, you're looking at inflated premium — which means you're collecting more as a seller, but also means a big move could still hurt you. Decide in advance what price you'd be comfortable getting assigned at, and only sell the put if you'd genuinely be okay owning shares there. If you wouldn't want the stock at that price, no amount of premium makes the trade worth it.

IV crush is a tool. Used with intention, it can accelerate your premium collection on the wheel. Used carelessly, it gives you false confidence right before an ugly assignment.
