On April 22, 2026, Tesla and IBM both reported Q1 earnings after the close. Both beat earnings-per-share estimates. But what happened to their options tells two very different stories about IV crush, and understanding the difference is one of the most practical skills an options trader can develop.
Key Takeaways
- IV crush is the collapse of implied volatility after a binary event like earnings; it happens regardless of which direction the stock moves.
- TSLA Q1 2026: initial +4% after-hours move that gave back all gains, ending near flat vs. a 5-10% implied move priced by options (a severe IV crush).
- IBM Q1 2026: stock fell 6.5% despite an EPS beat, roughly matching the implied move; IV crush was minimal here.
- An EPS beat does not guarantee a big move. The market reacts to guidance and surprises relative to expectations, not just the headline number.
- For options sellers, TSLA was the ideal earnings setup. For options buyers, it was a painful reminder of why the straddle buyer’s edge is elusive.
What Is IV Crush?
Implied volatility (IV) is the market’s consensus estimate of how much a stock will move over a given period. Before a scheduled event like earnings, IV rises as traders pay up for options protection or speculation. This elevated IV is what makes pre-earnings options expensive.
Once the event passes, the uncertainty is gone. IV collapses almost immediately after the announcement, regardless of the direction of the move. This collapse is IV crush. A straddle worth $15 before earnings might be worth $3 the morning after, even if the stock moved $5 in either direction, because the elevated IV that inflated the premium has evaporated.
IV crush is not a bug in the options market. It is the expected and rational repricing of uncertainty that has been resolved. The question for traders is whether the actual move is larger or smaller than what the market priced in before the event.
How to Measure the Expected Move Before Earnings
The options market prices an “expected move” into the nearest expiration before earnings. You can calculate it a few ways:
- ATM straddle price: The cost of buying the at-the-money call and put at the nearest expiration. This is roughly equal to the market’s expected one-standard-deviation move in dollar terms.
- Platform displays: tastytrade shows the expected move directly on the options chain header. thinkorswim displays it in the IV column. Most platforms show it somewhere near the chain.
- Rule of thumb: Divide the straddle price by the stock price to get the expected percentage move.
Before TSLA earnings on April 22, the options market was pricing approximately a 5-10% post-earnings move. Before IBM, the pricing implied roughly a 6.9% move in either direction.
Case Study 1: Tesla (TSLA), Classic IV Crush
The Setup
Tesla reported Q1 2026 results on April 22 after the close:
| Metric | Actual | Estimate | Result |
|---|---|---|---|
| EPS (adjusted) | $0.41 | $0.37 | Beat |
| Revenue | $22.39B | $22.64B | Miss |
| Vehicles delivered | 358,023 | ~365,600 | Miss |
| 2026 capex guidance | $25B | ~$20B prior | Above expectations |
What Happened
TSLA initially rallied approximately 4% in after-hours trading on the EPS beat. Then the company disclosed full-year capital expenditure guidance of $25 billion, well above the prior guidance of $20 billion. The stock gave back all of its gains and settled near flat to the pre-earnings close, a post-earnings move of roughly 0-2% when the options market had priced in 5-10%.
This is severe IV crush. The actual move came in at a fraction of what was priced. Options buyers who purchased straddles or strangles expecting a large move in either direction were hurt badly: not by being wrong about the direction, but by overestimating the magnitude of the move.
Hypothetical P&L: TSLA Straddle Buyer vs. Seller
The following example uses illustrative, hypothetical numbers to show the mechanics. It is not based on specific contract prices from April 22 and does not constitute a trade recommendation.
Hypothetically: a trader buys one ATM TSLA straddle (one call and one put at the same strike, nearest expiration) the day before earnings for a total cost of $14.00 per share ($1,400 per contract). The straddle priced in roughly a $14 expected move in either direction.
After earnings, TSLA settles approximately $2 above its pre-earnings close. The straddle value collapses as IV evaporates. The straddle is now worth roughly $3-4 (the intrinsic value of the winning leg minus decay). The straddle buyer’s loss on the position: approximately $10-11 per share, or $1,000-$1,100 per contract.
The straddle seller collected $1,400 at entry. After the IV crush and a modest actual move, the position is worth $300-$400. The seller’s gain: approximately $1,000-$1,100 per contract, the mirror image of the buyer’s loss.
This is the core dynamic of IV crush: the seller profits when the actual move is smaller than the priced move. The buyer profits only when the actual move exceeds the priced move. In TSLA’s case on April 22, the actual move came in well below the priced move, a clear sellers’ event.
Case Study 2: IBM, EPS Beat, Stock Down, Minimal IV Crush
The Setup
IBM also reported Q1 2026 results on April 22 after the close:
| Metric | Actual | Estimate | Result |
|---|---|---|---|
| EPS (operating) | $1.91 | $1.81 | Beat (+5.5%) |
| Revenue | $15.9B | ~$14.6B est | Beat (+9% YoY) |
| Free cash flow | $2.2B | N/A | Highest Q1 in a decade |
| Post-earnings move | -6.46% AH | ~6.9% priced | Move matched expectations |
What Happened
IBM beat on EPS by 5.5% and reported revenue up 9% year-over-year. Normally that would support a positive reaction. Instead, the stock fell 6.46% in after-hours trading. The likely driver: investors sold into strength, citing consulting revenue growth of only 4%, below the double-digit growth in other segments, and concerns about whether the AI-driven consulting boom is materializing fast enough.
Critically for options traders: IBM’s actual move of 6.46% was almost exactly what the market had priced in (roughly 6.9%). IV crush on IBM was minimal. Straddle sellers did not collect much edge; the move ate up most of the premium. Straddle buyers who chose IBM over TSLA were in a better position, though they needed to be directionally correct (short exposure via put) to profit cleanly.
What the TSLA and IBM Contrast Teaches
An EPS Beat Does Not Guarantee a Big Move
Both stocks beat EPS estimates. One collapsed in IV and barely moved. The other fell 6.5% on the beat. The difference was guidance and the market’s reaction to what lay beneath the headline number. Tesla’s capex increase spooked investors despite the EPS beat. IBM’s consulting growth disappointed despite strong overall revenue.
For options traders, this is a foundational insight: earnings trades are not about predicting the direction of the headline number. They are about predicting whether the actual market reaction will be larger or smaller than what the options market already has priced in.
IV Crush Is Most Severe When the Actual Move Is Small
TSLA gave options sellers a near-ideal outcome: maximum IV collapse with minimal actual movement. IBM gave sellers a mixed outcome: the move roughly matched the priced expected move, so neither seller nor buyer had a structural edge from the volatility pricing alone.
The question before every earnings trade should be: does this stock tend to move more or less than what the options are pricing? Historical data on how a stock has performed relative to its expected move over previous earnings cycles is the most relevant input for that question. Platforms like tastytrade and Interactive Brokers both show historical expected move vs. actual move data on the options chain.
For Options Sellers: TSLA Was the Better Setup
A premium seller running a short straddle or iron condor into TSLA earnings collected significant IV premium, then watched the stock do almost nothing. That is the best-case scenario for a short volatility position. The risk, as always, was that TSLA could have moved 15-20% (those earnings have happened before), in which case the seller would have faced a significant loss.
IBM was less compelling for sellers because the move matched the priced range. There was no “IV edge” to collect; the premium was priced fairly relative to the actual outcome.
Bottom Line
IV crush is not something that happens to you; it is the expected repricing of uncertainty after it resolves. Understanding it means understanding that options premium before earnings reflects the market’s probability distribution for the move, not just the direction. TSLA on April 22 showed IV crush at its most severe: premium sellers collected nearly full value while buyers saw most of their investment evaporate despite the stock moving. IBM showed a more neutral outcome where the market’s pricing was accurate. The lesson: focus less on which direction the stock will move and more on whether the priced expected move is realistic given the stock’s history.
FAQ
Q: Does IV crush happen after every earnings report?
A: Yes, always. Once the earnings event passes, the binary uncertainty that inflated IV is resolved. IV drops immediately regardless of whether the stock moved up, down, or nowhere. The magnitude of the crush depends on how elevated IV was beforehand and how big the actual move was.
Q: Can you profit from IV crush without knowing which direction the stock will move?
A: Yes, that is the core idea behind short straddles and iron condors into earnings. The seller does not need to predict the direction, only that the actual move will be smaller than the priced expected move. The risk is that if the stock makes a large unexpected move, the seller faces significant losses. Defined-risk structures like iron condors cap that loss.
Q: How do I know if the expected move is priced too high before earnings?
A: Compare the current expected move (from the ATM straddle price) against the stock’s historical post-earnings moves over the last 4-8 quarters. If the stock has historically moved an average of 5% on earnings and options are pricing 10%, that is a potential edge for sellers. If the stock has historically moved 12% and options are pricing 10%, sellers have the opposite problem. Most options platforms display this historical data alongside the chain.
Q: What happened to IBM options sellers on April 22?
A: They roughly broke even on the volatility component. IBM’s actual move of 6.46% was close to the 6.9% priced move, so the IV crush was modest. An iron condor seller would have needed the stock to stay inside a defined range; if IBM was inside their short strikes, they profited from the structure, not from IV crush specifically. A short straddle seller would have seen a move that roughly consumed their collected premium.
Q: Is selling options before earnings a reliable strategy?
A: Historically, the implied move tends to overestimate the actual move on average, meaning sellers have had a structural edge over time. But individual outcomes vary enormously, and a single large move can wipe out many cycles of premium collected. Traders who sell earnings volatility consistently size positions conservatively, use defined-risk structures, and never rely on any single trade as the basis of the strategy.
