Short Interest & FTDs
Options and Their Impact
Max Pain and Gamma
Options activity can significantly impact stock prices, especially around expiration dates. Understanding this helps predict price behavior.
Max Pain
Max Pain is the price at which option buyers would lose the most money (and option sellers profit most). Stocks often gravitate toward max pain by expiration.
Gamma Squeeze
When call options go "in the money," market makers must buy shares to hedge (delta hedging). This buying can push price higher, causing more calls to go ITM, creating a feedback loop.
GME $30 calls ITM → MM buys shares to hedge → Price rises to $35 → $35 calls go ITM → More hedging → Price spikes
Gamma squeeze feedback loop
