How the Mechanism Operates
Before a high-stakes binary event (e.g. Quarterly Earnings or General Election counting), uncertainty peaks, driving IV to extreme heights.
The moment the news is announced and the market opens, uncertainty vanishes completely. In the opening 15 minutes, Implied Volatility undergoes an immediate 'IV Crush'. Long straddle buyers who paid inflated premiums find their options collapsing in price even if the stock made a 3% move.
Furthermore, equity markets exhibit pronounced downside Volatility Skew. Institutional portfolio managers continuously buy downside OTM Puts to insure against market crashes. This structural demand bids up Put IV relative to Call IV, creating an asymmetric volatility surface.
Post-Earnings IV Crush on IT Blue Chip
TCS 4,200 Straddle traded at ₹160 on earnings eve with 48% IV.
TCS announced solid results and opened +1.8% higher at ₹4,275. IV collapsed instantaneously from 48% to 22%.
The 4,200 Call traded at ₹95 while the 4,200 Put collapsed to ₹10 (Combined Straddle = ₹105, delivering a -35% loss to long straddle buyers despite getting the direction right).
★ Never buy naked straddles right before earnings without accounting for the guaranteed post-result IV crush.
Non-Negotiable Risk Guidelines
Common Pitfalls & Remedies
Why it happens: IV Crush will destroy more value than the 2% delta gain can generate.
Remedy: Exit long options before the close on earnings day or switch to defined-risk credit spreads.
Frequently Asked Questions
Why do Puts have higher Implied Volatility than Calls in equity indices?
Because markets typically crash faster and more violently than they rise, creating immense institutional demand for downside crash insurance.
