Gamma squeezes are complicated and dangerous occasions, although not that frequent.
Right here’s every part you’ll want to find out about a gamma squeeze.
What’s a gamma squeeze?
A gamma squeeze happens when the shopping for stress for choices contracts triggers a speedy rise within the value of the underlying inventory.
Earlier than we dive in additional, it’s vital to grasp just a few fundamentals in regards to the choices buying and selling market.
Understanding choices
The choices market offers buyers the prospect to take a position on the longer term value actions of a inventory with out really proudly owning the shares.
Choices are contracts that grant the customer the correct, however not the duty, to purchase (name choices) or promote (put choices) a particular inventory at a predetermined value (the strike value) by a sure date (the expiration date).
On the opposite aspect of this transaction is usually a market maker, knowledgeable who facilitates choices buying and selling by offering liquidity. They’re at all times prepared to purchase and promote a particular safety at its quoted value, making a revenue on the bid-ask unfold within the course of.
Understanding a gamma squeeze
With that context in thoughts, a gamma squeeze is spurred by a sudden surge in shopping for exercise for name choices or promoting for put choices.
When numerous name choices — which signify 100 shares of the underlying inventory — are bought from a market maker, the market maker primarily turns into brief the inventory. The market maker has an obligation to ship the shares if the choice is exercised. If the inventory value rises, this brief place exposes them to probably limitless losses.
To hedge this threat, market makers purchase the underlying inventory itself to offset their brief place within the name choices. Satirically, this extra shopping for exercise from market makers propels the inventory value upwards — the alternative of what they need — making a snowball impact.
Because the inventory value climbs, it incentivizes much more name shopping for, thereby perpetuating the cycle.
Choices Greeks
Whereas choices typically mirror the worth actions of the underlying asset, their pricing is extra intricate than inventory costs. Choices merchants make the most of the “Greeks,” a set of letters representing variables that measure how various factors affect the worth of an choice.
Two essential Greeks within the context of gamma squeezes are delta and gamma.
- Delta: Delta tells you ways a lot the worth of an choice is predicted to vary in relation to a $1 motion within the value of the underlying inventory. For instance, a delta of 0.5 signifies that for each $1 enhance within the inventory value, the choice value is more likely to enhance by $0.50.
- Gamma: Constructing on delta, gamma measures the speed of change in delta itself. So, it primarily tells you ways rapidly the choice’s sensitivity to inventory value adjustments is accelerating.
Because the inventory value goes up, the market maker who offered name choices wants to purchase an increasing number of inventory to hedge the place. On this case, delta displays how a lot inventory they should purchase for every greenback enhance within the inventory value.
Right here’s the place it will get attention-grabbing: Delta additionally signifies the chance of a name choice expiring “within the cash,” that means the inventory value is above the strike value.
So, the upper the inventory value goes, the nearer the decision choices get to expiring within the cash, and delta climbs towards 1. This tells the market maker they should purchase near 100% of the underlying inventory to totally hedge their brief name place.
Now, think about this taking part in out on a large scale with hundreds of thousands of shares. Because the inventory value rises, the market maker will get “squeezed” and should purchase an increasing number of inventory to hedge their calls. The market maker’s extra shopping for solely fuels the rally — making a gamma squeeze.
3 substances of a gamma squeeze
Gamma squeezes aren’t that frequent, partially, as a result of a number of elements have to align good to set the phenomenon in movement.
