Gamma Squeeze
The Formal Definition
A self-reinforcing market phenomenon where heavy retail buying of short-dated out-of-the-money call options forces market makers to buy underlying stock to maintain delta-neutral hedges.
Hedging Volume = Σ (Open Option Contracts × Option Gamma × Share Multiplier)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"A gamma squeeze is retail weaponizing Wall Street's own risk models. When thousands of traders buy short-dated out-of-the-money calls, market makers must hedge by buying the actual stock. As the stock climbs, their delta increases, forcing them to buy even more stock."

Examining the real numbers for: Low-float stock trading at $20 with heavy retail call buying
| Execution Metric | Early Breakout Trader | Late FOMO Option Buyer |
|---|---|---|
| Fee / Rate | Standard ticket | $0.00 app trade |
| Spread / Buffer | Entered at $22 as delta hedging triggered | Bought $80 calls at peak mania |
| Execution / Status | Market makers forced to buy 4M shares to hedge | Gamma flipped negative as call buying slowed |
| Total Cost / Result | +195% gain driven entirely by institutional delta hedging | -98% total wipeout of option premium |
How Brokers Weaponize This Term
Payment for Order Flow wholesalers spot concentrated call buying early in retail order flow, allowing their proprietary desks to position ahead of predictable market-maker delta hedging flows.

What ends a gamma squeeze?
A gamma squeeze unwinds when retail call-buying volume slows, option contracts expire, or market makers begin selling off underlying shares as delta drops.
Why are short-dated options more potent for gamma squeezes?
Options closest to expiration have the highest gamma, requiring market makers to adjust their equity hedges rapidly for small moves in the underlying stock.
