# Call-Put Parity ⎊ Area ⎊ Resource 1 --- ## What is the Formula of Call-Put Parity? Call-put parity establishes a fundamental relationship between the price of a European call option, a European put option, the underlying asset's spot price, and the present value of the strike price. This principle dictates that a portfolio consisting of a long call and a short put should yield the same payoff as a long position in the underlying asset and a short position in a risk-free bond. The formula provides a theoretical benchmark for pricing options, ensuring consistency across different derivative instruments. ## What is the Arbitrage of Call-Put Parity? Deviations from call-put parity create arbitrage opportunities for quantitative traders. When the market price of the call-put combination does not align with the theoretical parity value, traders can execute a strategy involving simultaneous buying and selling of the mispriced instruments to capture risk-free profit. This arbitrage activity quickly forces the prices back into equilibrium, reinforcing the parity relationship in efficient markets. ## What is the Assumption of Call-Put Parity? The validity of call-put parity relies on several key assumptions, including that the options are European style, meaning they can only be exercised at expiration. Additional assumptions include zero transaction costs, no restrictions on short selling, and the ability to borrow and lend at a constant risk-free rate. In cryptocurrency markets, these assumptions are often challenged by high transaction fees and volatile interest rates, leading to temporary or persistent deviations from theoretical parity. --- ## [Put Options](https://term.greeks.live/definition/put-options/) A contract giving the right to sell an asset at a set price, used to hedge against or profit from price drops. ⎊ Definition ##
