Chooser option put call parity
For some of the more advanced option contracts, the closed form solution may not be so easy to obtain and thus a numerical method may be required. These numerical methods will be discussed in later parts, but first we present the closed form solution for one of the simplest types of option — the European vanilla call. Given the call option formula, we can chooser option put call parity the put-call parity to derive the price of the put option having the same underlying asset and strike price, which is given by.
Similarly, the value of a put option can also be obtained using binomial tree method or Monte Carlo simulation. The codes are pretty much the same as in the case of call option, with a few minor changes.
An American option can be exercised at any time, whereas chooser option put call parity European option chooser option put call parity only be exercised at the expiration date.
This added flexibility of American options increases their value over European options in certain situations. However it is suboptimal to exercise an American call option on a non-dividend-paying stock before the expiration date.
This is because for a given movement chooser option put call parity the stock price, the profit from holding an in the money call is equivalent to the profit from holding the stock. The call option, however, has the added benefit of protecting against the risk of a downward price movement below the strike price.
Additionally, because of the time value of money, it costs more to exercise the option today at a fixed strike price K than in the future at K. Finally, there is an intrinsic time value of the option that would be lost by exercising the option prior to the expiration date. Hence, the price of an American and European call option without dividends should be the same. The price of an American call option on an underlying asset that pays dividends, however, may diverge from its European counterpart.
For an American call with dividends it may be beneficial to exercise the option prior to expiration. However a closed form formula for American option does not exist as the optimal exercise time is not specified but a variable to be determined itself. Thus we have to resort to numerical methods to obtain the option price. A standard chooser option put call parity option gives its holder the right to choose, at a predermined time whether the T-maturity option is a standard European call or chooser option put call parity with a common strike price for the remaining time to expiration.
The payoff of the chooser option on the date of choice is. For notational chooser option put call parity, we take chooser option put call parity current time. Suppose the underlying asset pays a continuous dividend yield at rate. By the put-call parity relation, the above payoff function can be expressed as. Hence the chooser option can be viewed as the combination of one call with strike price and time to expiration and units of put with strike price and time to expiration.
Applying the Black-Scholes pricing approach, the value of the standard chooser option is given by. This is my implementation of the counting inversions algorithm for Stanford's MOOC [course on algorithm design and analysis][coursera].
European call option The Black-Scholes formula for the option price is given by where the option parameters are: The payoff of the chooser option on the date of choice is where is the time to expiry in both call and put price formulas above, and is the asset price at time. By the put-call parity relation, the above payoff function can be expressed as Hence the chooser option can be viewed as the combination of one call with strike price and time to expiration and units of put with strike price and time to expiration.
Applying the Black-Scholes pricing approach, the value of the standard chooser option is given by where is the current asset price and Reference Yue-Kuen Kwok. Mathematical Models of Financial Derivatives.
