This parity states that the value of a call option , at a specified strike price , implies a particular fair value for the corresponding put option , and vice versa. Thus, the price of a call and put should always hold a price relationship between one another. The theory behind this pricing relationship relies on the possible arbitrage opportunity that would result if there is a divergence between the value of calls and puts with the same strike price and expiration date.
Knowing how these trades work can give you a better feel for how put options, call options, and the underlying stocks intermingle. Key Takeaways Put-call parity is a principle that defines the relationship between the price of put and call options of the same on the same underlying asset with the same strike price and expiration date.
If the price of one of these options is out of line in relation to the parity equation, it presents a low-risk arbitrage opportunity to put the prices back in line. Common parity trades include establishing synthetic positions, boxes, and reversal-conversions. If the dividend increases, the puts expiring after the ex-dividend date will rise in value, while the calls will decrease by a similar amount.
Changes in interest rates have the opposite effects. Rising interest rates increase call values and decrease put values. The Synthetic Position Option-arbitrage strategies involve what are called synthetic positions. All of the basic positions in an underlying stock, or its options, have a synthetic equivalent. What this means is that the risk profile the possible profit or loss , of any position, can be exactly duplicated with other, but, more complex strategies.
The rule for creating synthetics is that the strike price and expiration date, of the calls and puts, must be identical. For creating synthetics, with both the underlying stock and its options, the number of shares of stock must equal the number of shares represented by the options. To illustrate a synthetic strategy, consider a fairly simple option position: the long call.
When you buy a call, your loss is limited to the premium paid while the possible gain is unlimited. Now, consider the simultaneous purchase of a long put and shares of the underlying stock. Once again, your loss is limited to the premium paid for the put, and your profit potential is unlimited if the stock price goes up.
Below is a graph that compares these two different trades. The options owner will have a stellar gain on the call option and the put option will become worthless. Step 5 Track the gain from owning the stock of the underlying company. Track the gained from owning both the call option and the put option. Both investment choices should emerge as equal assuming the company paid no dividends during the duration. Warning While option contracts give the investor a right to purchase or to put or sell the stock at a specified price during a specified period, the option contracts do not give the investor the same rights as owning the stock.
Owners of the stock will still maintain the right to vote and the right to receive dividends.
