Episode notes
How Dealer Delta Gamma Amplifies Moves
- Dealer hedging creates a direct transmission from option buying into share demand via delta and gamma adjustments.
- Brent explains dealers short calls buy shares as hedges and gamma measures how much hedges must change for a given move.
Gamma Squeezes Turbocharged Small Caps
- Short squeezes like GameStop and Avis illustrate how options-driven dealer hedging can turbocharge share rallies.
- Brent recounts Avis jumping from $80 to nearly $1,000 and how option flows created a gamma squeeze that supported the stock.
Use OPEX Windows To Anticipate Volatility Shifts
- Expect short-term volatility to compress into monthly OPEX and then expand afterward, creating transient turning points.
- Brent advises watching the post-expiration window because realized vol squeezes into OPEX then typically rebounds within days to weeks.
