Frequently Asked Questions

Can I profit from IV crush even if the stock moves?

Yes! That's the key insight. If IV drops enough, you can profit even if the stock moves - as long as it moves LESS than the implied expected move. For example, if expected move is 8% and stock moves 5%, the IV crush benefit can exceed the price move damage.

How do I know if IV is elevated enough for an IV crush trade?

Check IV Rank or IV Percentile. For IV crush trades, you want IV Rank above 50%, ideally above 70%. Also compare near-term IV to far-term IV - before events, near-term should be noticeably higher (term structure inversion).

What happens if the stock moves way more than expected?

You lose, potentially up to your maximum loss. With iron condors, this is defined (width minus credit). With naked straddles/strangles, losses can be severe. This is why position sizing (1-2% account risk) and defined-risk structures are essential.

Should I hold my IV crush position to expiration?

No! Close within 1-2 days after the event. The IV crush benefit is captured immediately. Holding longer exposes you to gamma/theta risk without the special event premium edge. Take your profit (or loss) and move on.

Why do options become cheaper after earnings even if the stock moved?

Because uncertainty is resolved. Before earnings, nobody knows the outcome - this uncertainty adds value to options (high IV). After earnings, the outcome is known - uncertainty gone, IV drops, options become cheaper. The stock can move and options still become cheaper.

How do I choose between iron condor, calendar, and butterfly for IV crush?

Iron condor: Most versatile, good for expecting any move within range. Calendar: Best when term structure is sharply inverted, or you have slight directional bias. Butterfly: Best when expecting price to pin near a specific level. Condor is the default choice for most situations.

What's the advantage of a calendar spread for IV crush?

Calendar spreads have defined risk (max loss is debit paid) and benefit specifically from term structure normalization. The near-term option you sold crushes harder than the far-term you bought. Works well when term structure is sharply inverted.

How should I handle UK earnings that release pre-market?

UK earnings typically release at 7 AM before market opens. The gap happens before you can react. Enter your position 1-2 days before, accept the overnight gap risk, and be ready to act at market open. Consider using slightly wider strikes for more cushion.

Is it worth trading IV crush on BoE decisions?

It can be, but with caution. BoE decisions have smaller IV inflation than earnings, and surprise decisions can cause large moves. Use wider structures, smaller position sizes, and focus on FTSE 100 options rather than individual stocks.

What if IV doesn't crush as much as expected?

This happens when the event creates more uncertainty rather than resolving it (e.g., unclear guidance, upcoming additional events). You'll profit less than expected. If this is identified early, consider holding slightly longer, but don't wait for perfect crush that may never come.

How do institutional traders think about IV crush differently than retail?

Institutions view it as systematic variance selling with portfolio-level risk management. They run multiple positions across sectors, track aggregate vega exposure, hedge tail risk, and focus on long-term edge capture rather than individual trade outcomes. Position sizing is based on portfolio volatility targets.

What's the role of demand asymmetry in creating the IV crush edge?

Retail traders disproportionately buy options before events (lottery ticket mentality), while sellers are fewer. Market makers must take the other side and charge premium for bearing risk. This demand asymmetry inflates IV beyond fair value, creating the edge for sellers.

How should backtesting account for event-day execution realities?

Event days have wider bid-ask spreads, higher slippage, and potential fill issues. Backtests should model 1.5-2x normal slippage for event-day exits. Also account for partial fills and the possibility that extreme moves make exits at theoretical prices impossible.

What's the relationship between IV crush edge and variance risk premium?

IV crush edge is a specific manifestation of variance risk premium concentrated around events. VRP exists because option sellers demand compensation for bearing uncertainty. Events amplify this - event VRP can be 2-3x normal VRP. Capturing event VRP is the fundamental source of IV crush profits.

How do you hedge tail risk in a systematic IV crush strategy?

Options include: (1) Using defined-risk structures exclusively, (2) Maintaining portfolio-level gamma limits, (3) Buying far OTM puts for crash protection, (4) Sizing positions so any single max loss is insignificant, (5) Diversifying across uncorrelated events and sectors. No perfect hedge exists - some tail risk acceptance is inherent.
