# Short Call ⎊ Definition **Published:** 2025-12-19 **Author:** Greeks.live **Categories:** Definition --- ## Short Call A short call is a strategy where an investor sells a call option they do not necessarily own. The seller receives the premium but takes on the obligation to sell the underlying asset if assigned. This strategy has significant risk if the stock price rises substantially. It is typically used by traders who expect the underlying asset to remain stable or decline. It involves selling the right to buy. - [Naked Short](https://term.greeks.live/definition/naked-short/) - [Covered Call](https://term.greeks.live/definition/covered-call/) - [Long Call](https://term.greeks.live/definition/long-call/) - [Call Skew](https://term.greeks.live/definition/call-skew/) ## Glossary ### [Short Rate Models](https://term.greeks.live/area/short-rate-models/) Model ⎊ Short rate models are mathematical frameworks used in quantitative finance to describe the stochastic behavior of interest rates over time. ### [Call Options](https://term.greeks.live/area/call-options/) Application ⎊ Call options, within cryptocurrency markets, represent a financial contract granting the buyer the right, but not the obligation, to purchase an underlying crypto asset at a predetermined price—the strike price—on or before a specified date, the expiration date. ### [Put-Call Parity Deviation](https://term.greeks.live/area/put-call-parity-deviation/) Arbitrage ⎊ Put-Call Parity Deviation, within cryptocurrency options, represents a quantifiable difference from the theoretical relationship between a call option, a put option, the underlying asset price, the strike price, and the risk-free interest rate. ### [OTM Put Call Parity](https://term.greeks.live/area/otm-put-call-parity/) Parity ⎊ This principle asserts an equivalence in value between a specific portfolio of an out-of-the-money (OTM) put option, the underlying asset, and a risk-free bond, contingent on the option expiring worthless. ### [OTM Call Sale](https://term.greeks.live/area/otm-call-sale/) Premium ⎊ The core objective of this trade is the collection of the upfront cash received from selling the option contract to the buyer. ### [Multi-Call Transactions](https://term.greeks.live/area/multi-call-transactions/) Transaction ⎊ Multi-Call Transactions, within cryptocurrency and derivatives contexts, represent a sequence of operations executed atomically across multiple smart contracts or decentralized applications. ### [Short-Dated Options Economics](https://term.greeks.live/area/short-dated-options-economics/) Economics ⎊ ⎊ Short-Dated Options Economics are characterized by rapid time decay, or theta, which significantly compresses the option's extrinsic value over a brief horizon, making them highly sensitive to immediate market catalysts. ### [OTM Call Options](https://term.greeks.live/area/otm-call-options/) Option ⎊ An OTM call option grants the holder the right, but not the obligation, to purchase an underlying asset at a specified strike price before or on the expiration date. ### [Short Position Collateral](https://term.greeks.live/area/short-position-collateral/) Collateral ⎊ Short position collateral refers to the assets deposited by a trader to cover potential losses from a short sale. ### [Short-Term Hedging Pressure](https://term.greeks.live/area/short-term-hedging-pressure/) Action ⎊ Short-Term Hedging Pressure manifests as rapid adjustments to derivative positions, particularly options, in response to fleeting market movements within cryptocurrency. ## Discover More ### [Covered Call Vaults](https://term.greeks.live/term/covered-call-vaults/) ![A close-up view reveals a precise assembly of cylindrical segments, including dark blue, green, and beige components, which interlock in a sequential pattern.
