A risk-first framework for navigating scheduled volatility — earnings, CPI, FOMC, and NFP — how implied volatility crushes after the event, why sizing must shrink before unknown outcomes, and the strategies that survive a gap.
Key Takeaways
- Scheduled events (earnings, CPI, FOMC, NFP) cause implied volatility to spike before and crush after.
- Pre-event option buying pays a volatility premium that often evaporates the moment news drops.
- Gap risk dominates: the post-event open can skip straight past your stop.
- Reduce size before unknown outcomes — never risk your normal 1%–2% on a binary event.
- Defined-risk structures (spreads) and post-event re-entries are safer than naked pre-event bets.
Why Events Are Different
A scheduled event — an earnings print, a CPI release, an FOMC decision, a nonfarm payrolls report — converts uncertainty into known information in a single instant. Before the event, the market prices that uncertainty as elevated implied volatility. After the event, the uncertainty is resolved and implied volatility collapses, a phenomenon known as IV crush. Trading events is therefore as much a volatility trade as a directional one.
Key Takeaways
- Event trading is a volatility trade, not just a directional one.
- IV crush can make a correct directional bet still lose money.
- Gap risk means your stop may not fill where you placed it.
The IV Crush Problem
A stock at $100 has earnings tomorrow. The $100 call costs $4 because implied volatility is high. Earnings are good and the stock opens at $102 — but IV collapses, and the call now trades at $2.50. You were right about direction and still lost 37%.
This is why buying naked options before earnings is structurally disadvantaged: you pay the highest implied volatility of the cycle, and the moment the news lands, the premium you paid evaporates even if you called the direction correctly.
Gap Risk: The Stop That Does Not Fill
Events frequently produce opening gaps — price opens far from the prior close, skipping the entire range where your stop sat. A stop-loss order placed at $95 on a stock that closed at $98 and gapped open at $90 fills near $90, not $95. Your intended 3% loss becomes a 10% loss. This is the single most dangerous feature of event trading and the reason position size must shrink.
A Risk-First Event Framework
Before any scheduled event, decide whether the trade justifies the gap risk. The professional default is to reduce size to a fraction of normal — often 0.25%–0.5% of equity — so a worst-case gap is survivable. Use the TradeRiskMath position-sizing calculator with a deliberately smaller risk percentage for event trades, and prefer defined-risk structures (vertical spreads) whose maximum loss is contractually capped at the debit paid.
Strategy Options for Events
| Approach | When | Risk Profile |
|---|---|---|
| Stand aside | Always acceptable | Zero risk; miss the move |
| Pre-event spread | You have a directional view | Defined risk = debit paid |
| Post-event re-entry | After the gap settles | Normal risk; no IV crush exposure |
| Straddle/strangle | You expect a big move, no direction | High cost; needs a very large move |
For most traders, the highest-EV choice is to wait for the event to pass and trade the post-event setup — the direction is clearer, IV has crushed (so options are cheaper), and gap risk is gone. The move you miss is the chaotic first minutes; the move you capture is the more reliable follow-through.
Macro Releases: CPI, FOMC, NFP
Macro events move entire asset classes simultaneously. A hot CPI print can gap equity indices, bonds, gold, and the dollar in one print. The same rules apply: reduce size, avoid naked pre-event options, and prefer to trade the post-release reaction once the initial spike-and-reversal noise settles. Forex traders should be especially cautious around NFP and FOMC, when spreads widen and stops get swept.
Frequently Asked Questions
Should I hold through earnings?
Only if the position is sized for a worst-case gap and you accept that a correct view can still lose to IV crush. Many traders close or reduce before earnings and re-enter after.
What is IV crush?
The rapid drop in implied volatility after a scheduled event resolves uncertainty. It shrinks option premiums even when the underlying moves in your favor, often turning a “correct” directional bet into a loss.
Can I trade the event itself?
You can, but you are trading a binary outcome with gap risk and IV crush. Defined-risk spreads and reduced size are the only responsible ways to do it; most edges sit in the post-event follow-through.
The Bottom Line
High-volatility events reward preparation and punish bravado. Implied volatility crushes after the news, gaps can blow past your stop, and a correct directional call can still lose. Reduce size before unknown outcomes, prefer defined-risk spreads, and recognize that the cleanest, highest-EV trade is often the post-event re-entry once the chaos settles. Event trading is survival-first, not prediction-first.
