In financial mathematics, put-call parity defines a relationship between the price of a European call option and a European put option - both with the identical strike price and expiry. Let S denote the (unknown) underlier value at expiration. http://en.wikipedia.org/wiki/Put-call_parity   (550 words)      PUT-CALL Parity Relation: Implications But we know from put-call parity, that (holding the other five variables fixed) if an increase in volatility raises the value of a call, it must also raise the value of a put, and by the same amount. Although there may be other determinants of option prices, given these five variables, they must affect European call and put prices in the same direction and by the same amount. Again, rearranging the formula shows that the sole determinants of the difference between the prices of otherwise identical European calls and puts are five variables: the current underlying asset price (S), strike price (K), time-to-expiration (t), riskless return (r), and payout return (d). http://www.in-the-money.com/presentation/sld049.htm   (551 words)      Options & Put-Call Parity (Page 1 of 2) In this case, his or her gain from buying the put is equal to the exercise price (E) minus the current market price of the asset when the option is exercised (S) minus the fee paid for the put (P). In this case, the gain from buying the call is the current market price of the asset when the option is exercised (S) minus the exercise price (E) minus the fee paid for the call (C). When an investor buys a call, they are given the right, but not the obligation, to buy a particular quantity of the underlying asset at a predetermined price (called the exercise or strike price) at some date in the future. http://www.teenanalyst.com/advanced/options.html   (969 words)      CHAPTER 1 If the call is a European call, you should buy the call, deposit in the bank an amount equal to the present value of the exercise price, and sell the stock short. One way to profit from Hogswill options is to purchase the call options with exercise prices of $90 and $110, respectively, and sell two call options with an exercise price of $100. Thus, to replicate the payoffs for the put, you would buy a 26-week call with an exercise price of $100, invest the present value of the exercise price in a 26-week risk-free security, and sell the stock short. http://www.math.uconn.edu/~bridgeman/Classes/Corporate_finance/Ch20x.htm   (2407 words)      Online Stock Trading - Put-Call Parity - MSO Put-call parity defines the relationship between put and call prices for non-dividend paying European options; the relationship also works well with most American options (when the put is not deep in the money). Stock Price = Call Price - Put Price + PV(K) This relationship exists because the payout of holding a call, a short put, and a risk-free investment with future value of K (at the expiration date) will be equal to the price of the stock at expiration. It is often useful to check call and put prices before you purchase a stock. http://www.mrswing.com/artman/publish/article_1684.shtml   (928 words)      Value Line Another example as illustrated in Graph 1 is that if you are considering a covered call, you should also look at the alternative of writing the put at the same strike price and fully collateralizing it with cash to cover the strike price value. You will also notice that when we use this $105 price as the underlying, the calculated time premiums of the puts and calls at the same strike prices come out to be exactly the same. If the current stock price is $100 dollars, the one-year interest rate is 6% and the dividend rate is 1% p.a., then the real cost of the stock for a one-year option is $105. http://www.valueline.com/edu_options/rep7.html   (1017 words)      Put-call parity with futures For arbitrage-free equilibrium we must have c-p=0; that is, at a strike-price equal to the futures price calls and put have the same price. Consult a newspaper for current prices for the options and futures of BHP to see to what extent the prices of a put and call become equal at the point where the strike price equals the futures price. This applet is set for buying a futures at $100, and buying a call and selling a put, both at a strike price equal to the futures price. http://matilda.vu.edu.au/~drw/frm/hull/ch09/nine09.html   (102 words)      Glossary - Quanto Financial Technology Purchasing power parities (PPPs) are the rates of currency conversion that equalize the purchasing power of different currencies by eliminating the differences in price levels between countries. A put option confers the right but not the obligation to sell currencies, instruments or futures at the option exercise price within a predetermined time period. Since the put option increases the value of the bondholder, bonds with put features provide lower yields than bonds with no put feature. http://www.equanto.com/glossary/p.html   (2038 words)      Put-Call Parity and Arbitrage Opportunity As long as the call and put have the same strike price and expiration date, a synthetic short/long stock position will have the same profit/loss potential as shorting/owning 100 shares of stock (ignoring dividends and transaction costs). Put-call parity is one of the foundations for option pricing, explaining why the price of one option can’t move very far without the price of the corresponding options changing also. Now consider the simultaneous purchase of a long put and 100 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. http://www.investopedia.com/articles/optioninvestor/05/011905.asp   (741 words)      Put-Call Parity The call option and an amount of cash equal to the present value of the strike price. is a relationship, first identified by Stoll (1969), that must exist between the prices of European put and call options that both have the same underlier, strike price and expiration date.

Given that all of the other components of the option prices are known and equal, it follows that a relationship must exist between the value of a call and that of its corresponding put. Assuming MSFT is currently trading at $27.54, suppose you purchase an April 2004 $27.50 call for $1.35. http://www.traders.com/documentation/feedbk_docs/archive/062004/Abstracts_new/Mendoza/mend.html   (454 words)      Advani Share Brokers As margins are paid on all three positions, the trader must ensure that returns on the strategy exceed the cost of capital.
