Directionally neutral; betting that IV will drop more than price will move
| Strategy Type | Event-driven volatility - Profits from implied volatility collapse after known events |
| Market Outlook | Directionally neutral; betting that IV will drop more than price will move |
| Risk Profile | Varies by structure - can be defined or undefined risk |
| Reward Profile | Profits from vega collapse; limited to premium differential captured |
| Time Horizon | Very short - typically 1-3 days around specific events |
| Iv Environment | Enter when IV is ELEVATED due to upcoming event; profit when IV CRUSHES post-event |
| Breakeven | Depends on structure; need IV drop to exceed adverse price move impact |
| Alternative Names | Earnings Crush, Volatility Crush Trade, Event Vol Selling, Post-Event Play |
| Primary Instruments | UK single stock options around earnings; FTSE options around BoE/economic data |
| Fca Compliance | Standard listed options; sophisticated strategy requiring event timing expertise |
| Contract Size | 1,000 shares for UK equity options; £10 per point for FTSE |
| Trading Hours | 08:00 - 16:30 GMT; be aware of overnight gap risk for earnings |
| Expiry Options | Target expiration shortly after event for maximum IV crush capture |
| Settlement | UK equity options American-style (physical); FTSE European-style (cash) |
| Margin Requirements | Varies by structure - naked short options require substantial margin |
| Uk Earnings Calendar | UK companies typically report half-year and full-year results; some quarterly |
| Uk Economic Events | BoE rate decisions (8/year), CPI, employment, GDP, PMI data |
| Timing Note | UK earnings often released pre-market (7:00 AM) - different from US after-hours pattern |
| Stamp Duty | No stamp duty on options |
| Tax Treatment | Capital Gains Tax on profits |
| Risk Warning | IV crush strategies have LIMITED PROFIT potential but can have SUBSTANTIAL LOSSES if the underlying moves significantly more than expected. The event outcome is binary and unpredictable. One large adverse move can wipe out many successful IV crush trades. |
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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
