3. Why the 5000 Strike Matters
While the 6400 strike has more "dollar" variance, the 5000 strike's percentage increase is what substantiates the "disaster" headline.
- Premium Growth: The 5000 put has increased by roughly 4,000% (from ~$0.10 to over $4.50) in just one month.
- Implied Volatility (IV): The IV for these deep out-of-the-money puts has moved into the 89th percentile, meaning the market is charging a massive premium specifically for a "black swan" event.
