Cash-secured puts during earnings
Last updated: May 30, 2026 · Cash-Secured Puts series
Earnings season is the most dangerous and most profitable window for premium sellers. Implied volatility ramps up in the days before an announcement and collapses immediately after. If you sell a CSP into that volatility spike and the stock doesn't move much, you make money from both theta and vega crush. If it moves a lot, you lose more than the premium can compensate.
The honest answer: experienced traders sometimes sell CSPs around earnings deliberately. Most retail traders shouldn't. The math looks favorable but the variance kills accounts.
Why IV spikes into earnings
The market doesn't know what AAPL will report. It does know the company is about to release information that will move the stock. Uncertainty = priced as higher implied volatility.
A typical pattern:
- 2-3 weeks before: IV starts ramping. A 30-day option might trade at 30% IV instead of the underlying's normal 22%.
- Day before: IV peaks. The 30-day option might be at 45-55% IV.
- Day of (after the report): IV collapses within minutes. Back to 22-25%.
That collapse is called “IV crush.” If you sold the option before earnings and the stock moves less than the implied move, you profit from both:
- The vega component drops (premium collapses)
- The theta component continues (time passes)
Worked example: NVDA earnings
NVDA at $212 the day before earnings. The market's implied 1-day move is ~7% ($15 in either direction). You sell a $190 put (well below the implied move) expiring in 7 days for $3.50 premium.
Three outcomes:
1. NVDA moves less than 7% after earnings. The next morning NVDA opens at $215. IV crushes from 65% to 35%. Your $3.50 put is now worth $0.80. You buy it back, take an $270 profit in 24 hours.
2. NVDA moves down 8% to $195. Your put is still OTM but barely. It's now worth $4.50. You lost $100 on premium but you're still safely above your strike.
3. NVDA moves down 15% to $180. Your put is now ITM. If you ride to expiration, you'll be assigned at $190 — buying NVDA at $190 when it trades at $180, an unrealized loss of $1,000 per contract.
You collected $350 to take this risk. Whether it was a good trade depends on whether you'd be comfortable owning NVDA at $190 (the effective $186.50 cost basis after premium).
When earnings CSPs make sense
Three conditions need to hold:
1. You'd genuinely own the underlying at the strike. This is the same rule as any CSP, but it matters more for earnings trades. The premium-chasing trap is most dangerous here.
2. You sell below the implied move. If the market implies a ±8% move and you sell a 6% OTM put, you're betting the actual move stays inside the expected range. Most of the time it does, but the times it doesn't are painful.
3. Position size is small. An earnings CSP can have 2-4x the realized variance of a normal CSP. Cut your position size by half to compensate.
When to skip them
Skip earnings CSPs if:
- You're a beginner. Build experience with non-event CSPs for at least 6-12 months first.
- You're trading a name with historical earnings gaps (NFLX, ZM, ROKU). Some names regularly move 15-25% on earnings; the math doesn't work.
- The underlying is in a volatile sector trend (regulatory uncertainty, AI hype cycle peaks). Industry-wide risk amplifies single-name earnings risk.
- You don't have other CSPs going to balance the risk. Earnings CSPs need to be a small fraction of your total premium-selling activity.
The safer alternative: sell after earnings
If earnings risk makes you nervous, just wait. The day after earnings, IV is still elevated for a few days as the market digests the report. You can capture some of the rich premium without the gap risk of the announcement itself.
Specifically: sell CSPs 1-2 days after earnings when the stock has settled into its post-earnings range and IV is still 10-20% higher than normal. You get most of the premium benefit with much less variance.
FAQ
How much premium can I collect on an earnings CSP?
Typical earnings-week CSPs at -0.20 to -0.30 delta produce 2-3x the premium of a non-earnings CSP on the same name. NVDA at -0.25 delta might pay $1.50 normally and $4.50 during earnings week.
Should I close earnings CSPs before the announcement?
If you're nervous, yes. Closing right before the announcement at the IV peak means you give up the IV crush profits but eliminate the gap risk. Most experienced sellers hold through (collecting the crush) but with smaller size.
What's the typical IV crush after earnings?
30-50% reduction in IV over the first 24 hours after the announcement. Specific magnitude depends on how much the stock moved (smaller moves = larger crush) and the name's typical earnings behavior.
Are earnings CSPs allowed in IRAs?
Yes, as long as they're cash-secured and the underlying is options-approved in the account. No regulatory restriction on event-driven trading inside IRAs.
