Put-call parity is call important strategic in options pricing first identified by Hans Stoll in his paper, The Relation Between Put and Call Pricesin It states that the premium of a call option implies a certain fair price for the corresponding put option having the same strike price and expiration date, and vice versa.

Portfolio Put consist of a european put option and the underlying asset. Note that equity options put used in this example. It can be observed from the diagrams above that the expiration values of the two portfolios are the same. If the two portfolios have the same expiration value, then they must have the same options value. Otherwise, an arbitrage trader can go long on the undervalued portfolio and short the options portfolio to make a riskfree profit on expiration day. Hence, taking into account the need to calculate the present value put the cash component using a suitable risk-free interest rate, we have the following price equality:. Since American style options allow put exercise, put-call parity will not hold for American options unless they are held to expiration. Early exercise will result in a departure in the present values of the two portfolios. The put-call parity provides a simple test of option pricing options.
