Lagrange's Formula I collect option pricing formulas. The book you have before you is a copy of this collection. As opposed to cars, one can easily share a collection of option pricing formulas with others.

A collection like this would naturally not have been possible if it weren't for all the excellent researchers both in academia and in the industry who willingly share their knowledge in various publications.

Persons who collect stamps usually arrange their stamps under some kind of system—their issue year, what country they come from, and so on. I have organized my collection of option pricing formulas in a similar fashion. Each formula is given a reference and the year when it was first published. This should make it easier to understand the various option pricing models, as well as be of value to anyone who wants to check his or her computer implementation of an option pricing formula.

To better illustrate the use and implementation of option pricing formulas, I have included examples of programming codes for several of them. Programming codes for most of the formulas, together with ready-to-use spreadsheets, are included on the accompanying CD.

Most of the formulas implemented also contains 3-D charts to illustrate the value or the various risk parameters of the option. By using this computer code in combination with the book, you should no longer view options pricing as a black box. The book differs from other texts on options pricing in the way I have tried to cut accompanying text to the bone. Text is included to illuminate the essence of implementing and applying the option pricing formulas.

This should make it easy and efficient to find the formula you need, whether it is to close a multimillion-dollar options contract without being ripped 1 To the best given by my knowledge, that naturally is incomplete. This collection of option pricing formulas is not intended as a textbook in option pricing theory but rather as a reference book for those who are already familiar with basic finance theory.

However, if you think that a collection of option pricing formulas is useful only to theoreticians, you are wrong. The collection does not contain lengthy deductions of option pricing formulas 2 but rather the essence of options pricing. Most of these formulas are used daily by some of the best talent on Wall Street and by traders in financial centers worldwide. The collection of option pricing formulas is an ideal supplement for quants, quant traders, financial engineers, students taking courses in option pricing theory, or anyone else working with financial options.

Morgan Chase. Over many years, I collected everything I came across on the valuation of options. My collection of articles and books on the subject has increased every year. In order to see the large picture of the various option pricing models, as well as to avoid carrying around a heap of books and papers, I decided to compile the most central option pricing formulas into a book: Few, if any, financial markets have seen such explosive growth and new developments as the options markets.

Continuously, new products are under development. With a few exceptions, I have chosen to collect option pricing models that can be used by practitioners. In a collection of formulas such as this, errors are particularly destructive.

A great deal of effort has been put into minimizing typing errors. I hope that readers who find any remaining errors will call them to my attention so that they may be purged from any future editions.

You can find my e-mail at www. A table of all the option pricing formulas is included following the table of contents, giving an overview for easy reference. The table gives a short description of the key characteristics of all the option pricing formulas included in this book.

If you are working with an option pricing problem, this table should be a natural starting point. Definitions of symbols are naturally important in a collection such as this. I have tried to define symbols in accordance with the modern literature.

Currently, use of symbols in the theory of options pricing is far from standardized. Following the Option Pricing Overview is a Glossary of Notations, which you will find useful when using this collection. Hui, P.

It has been a pleasure to work with the people at McGraw-Hill. In particular, I'm grateful for many helpful suggestions and assistance from Stephen Isaacs and Kevin Thornton. Enjoy the world of option formulas and option trading; must the most powerful formulas be on your side in good and bad times!

If you already have the first edition, you probably wonder what is new in the second edition. Even before the first edition was published, I started working on the second edition. First, my plan was to make a few improvements and add a couple of formulas. But over the years the number of new formulas and improvements just took off. As you will see, the second edition contains more than double the amount of information and formulas as the first edition.

In fact, writing the second edition involved more work than writing the first edition itself. In particular, the second edition contains much more coverage on option Greeks option sensitivities , while the first edition just touched upon this topic, as have most other option textbooks. You'll find the second edition goes far beyond anything you have seen published on this topic.

The number of new exotic options and derivatives that I have added to the second edition is astonishing.

Just to mention a few: The book also contains descriptions and implementations of stochastic volatility models, variance and volatility swaps, generalized jump diffusion models, and skewness and kurtosis models, among other nonstandard models and products. With regard to numerical methods, I have added a lot of information in how to use tree models—for example, to value a lot of different complex exotic options.

The second edition also covers finite difference methods and Monte Carlo simulation. The second edition also contains many new formulas and implementations for calculating volatility and risk parameters. It also contains sophisticated stochastic volatility models, as well as advanced Monte Carlo methods.

Literally tens of thousands of people, including traders, market makers, and salespeople, use option formulas several times a day. Hardly any other area has seen such dramatic growth as the options and derivatives businesses. In this chapter we look at the various versions of the basic option formula.

Unfortunately, Fischer Black died of cancer in before he also would have received the prize. It is worth mentioning that it was not the option formula itself that Myron Scholes and Robert Merton were awarded the Nobel Prize for, the formula was actually already invented, but rather for the way they derived it — the replicating portfolio argument, continuoustime dynamic delta hedging, as well as making the formula consistent with the capital asset pricing model CAPM.

The continuous dynamic replication argument is unfortunately far from robust. The popularity among traders for using option formulas heavily relies on hedging options with options and on the top of this dynamic delta hedging, see Higgins , Nelson , Mello and Neuhaus , Derman and Taleb , as well as Haug for more details on this topic.

In any case, this book is about option formulas and not so much about how to derive them. Sdt o- Sdz, where t is the expected instantaneous rate of return on the underlying asset, a is the instantaneous volatility of the rate of return, and dz is a Wiener process. BlackScholes "c", 60, 65, 0. This can be done numerically using several different methods and is covered in Chapter 7. The model can be used to price European call and put options on a stock or stock index paying a known dividend yield equal to q: The option premium is then paid into a margin account which accrues interest while the option is alive.

Such contracts trade on, for example, the Sydney Futures Exchange. What is the option value when the option premium is fully margined? The model is mathematically equivalent to the Merton model presented earlier.

The only difference is that the dividend yield is replaced by the risk-free rate of the foreign currency r f: Hence, if the option has a notional of million EUR, the total option premium is 1,, GBlackScholes " p," 75, 70, 0. An alternative is to solve the PDE numerically. This method is slower but more flexible. It is covered in Chapter 7. One can alternatively rewrite this PDE in terms of ln S. An arbitrage opportunity exists if the parity does not hold.

This is based on several assumptions—for instance, that we can easily short the underlying asset, no bid-ask spreads, and no transaction costs. It does not, however, rely on any assumptions about the distribution of the price of the underlying security. What is the value of a put with the same parameters? The result is naturally based on using the same volatility for call and put options.

Put-call parity will normally ensure this symmetry, but it may not hold in markets where there are restrictions on short selling, or other market imperfections. A call with strike X is thus equivalent to puts with strike 5ex This symmetry is useful for hedging and pricing barrier options, as shown in Chapter 4.

Consider next the following state space transformation: The result simplifies coding and implementation of many option calculations. There is no longer a need to develop or to code separate formulas for put and call options. The put-call supersymmetry can be extended to many exotic options and holds also for American options. See Adamchuk , Peskir and Shiryaev , Haug , and Aase for more details on supersymmetry as well as a discussion on negative volatility. The variance form is used indirectly in terms of its partial derivatives in some stochastic variance models, as well as for hedging of variance swaps, described in Chapter 6.

The BSM on variance form moreover admits an interesting symmetry between put and call options as discussed by Adamchuk and Haug at www. This section offers a quick overview of some of the most important precursors to the BSM model. In contrast to Black, Scholes, and Merton, Bachelier assumed a normal distribution for the asset price—in other words, an arithmetic Brownian motion process dS.

This implies a positive probability for observing a negative asset price—a feature that is not popular for stocks and any other asset with limited liability features. The current call price is the expected price at expiration. In this way he ruled out the possibility of negative stock prices, consistent with limited liability. Sprenkle moreover allowed for a drift in the asset price, thus allowing positive interest rates and risk aversion Smith, Boness derives the following value for a call option: In this way he allowed for positive interest rates and a risk premium.

Ito's lemma is a powerful tool to value derivative securities, for example, by helping us find a BSM partial differential equation PDE that can solved for the price, with the appropriate boundary conditions. Assuming that the asset price follows a geometric Brownian motion, 1.

The value of the portfolio: The idea was later extended by Thorp and Kaussof and Thorp and was further extended 1. Continuous time delta hedging as just described is removing all risk all the time under some strict theoretical assumptions. Unfortunately continuous dynamic delta hedging is far from robust in practice.

Dynamic delta hedging removes a lot of risk compared to not hedging or even static delta hedging. Unfortunately, options are extremely risky instruments, and even after removing a lot of risk there is more than plenty of risk left. That is, in practice dynamic delta hedging alone cannot be used as an argument for risk-neutral valuation.

See Haug for more references and detailed discussion on this topic. We will here just briefly discuss a more robust alternative to the dynamic hedging argument, namely, the Derman-Taleb method. They are starting out by the valuation methods used before BlackScholes-Merton, simply by discounting the expected pay off ffom an option based on an assumption on the distribution of the underlying asset at maturity. R is the discount rate including a unknown risk premium.

Next assuming the forward price is strictly based on arbitrage pricing. Based on this we know the forward price of a stock not is dependent on the real expected drift in the stock, but simply on the risk-free rate and naturally dividend, but here we for simplicity skip dividend even if the conclusions would be the same.

Second Derman-Taleb takes advantage of the put-call parity, see Nelson Combining equation 1. The formula is no longer dependent on dynamic delta hedging, neither directly on the CAPM formula. The method is based on a pure arbitrage argument and is extremely robust and is fully consistent with continuous-time as well as discrete-time trading.

This method is also the simplest method consistent with the volatility smile, see Haug The Derman-Taleb method is in this respect not a model that directly describes the stochastic process of the underlying asset or the dynamics of the volatility. It is a pure arbitrage argument as well as relative value arbitrage argument that actually is extremely robust and basically is how options traders operate by hedging away most option risk with other options, and on top of this are using dynamic delta hedging.

A consequence of this argument as discussed by Haug is that option valuation also must be dependent on supply and demand of options. There is still a link towards the underlying asset, but this link is only of the weak form, and not of the strong form assumed by Black, Scholes and Merton where all derivatives can be created synthetically without taking risk.

In other words, option traders need to take into account both the dynamic process of the underlying asset as well as the supply and demand for options when valuing options. This is actually the way option trader's use option formulas. Find the rules, or 'laws,' connecting the two prices. The partial derivative is a measure of the sensitivity of the option price to a small change in a parameter of the formula. Appendix B at the end of this chapter contains more details on how to derive the partial derivatives.

The second part of this chapter covers how to numerically compute option sensitivities. A large part of this chapter is based on Haug For a quick reference, many of the option sensitivities described in this chapter are listed in Table Figure 2 similarly illustrates the delta of a put option.

Example Consider a futures option with six months to expiration. For a European call option on a nondividend-paying stock, N di is moreover equal to the option's delta. Delta can therefore never exceed 1 for this option. For general European call options, delta is given by e b—r T Md1. If the term e b—r T is larger than 1 and the option is deepin-the-money, the delta can thus become considerably larger than 1.

This occurs if the cost-of-carry is larger than the interest rate, or if interest rates are negative. Figure 3 illustrates the delta of a call option. As expected the delta exceeds 1 when time to maturity is large and the option is deep-in-the-money.

What is the delta of a call option? The weakness of this approach is that it works only for symmetric volatility smiles. In practice, you still often need only an approximately delta neutral strangle. Moreover, volatility smiles are often more or less symmetric in the currency market.

Given identical strikes for a put and a call, what asset price will yield the same absolute delta value? Notice that the maximal gamma and vega, as well as the delta-neutral strikes, are not at-the-money forward as assumed by many traders.

Moreover, an in-the-money put can naturally have absolute delta lower than 0. This is as expected, as we have to adjust the strike accordingly. This is a common quotation method in, for instance, the OTC currency options market, where one typically asks for a delta and expects the salesperson to return a price in terms of volatility or pips as well as the strike, given a spot reference. In these cases, one needs to find the strike that corresponds to a given delta.

Several option software systems solve this numerically using NewtonRaphson or bisection. This is actually not necessary, however.

With an inverted cumulative normal distribution function N -1 0, the strike 1 This clearly also applies to commodity options when the cost-of-carry is r. The algorithm of Moro is one possible implementation; this is given in Chapter Example What should the strike be for a three-month call stock index option to get a delta of 0.

Sometimes when we, for example, value an option on a stock inputting the stock price, we can in some markets choose if we want to hedge with the stock itself or alternatively hedge with the stock futures.

Alternatively, you could naturally have inputted the futures price directly into the BSM formula, and the spot delta would in that case be equal to the futures delta. In the case where you hedge with a forward contract with same expiration as the option, the formula above also holds. This is particularly useful in the FX market, where you typically can choose between hedging with the currency spot or alternatively a forward with expiration matching the option expiration.

They both measure approximately how much delta will change due to a small change in the volatility, and how much vega will change due to a small change in the asset price: The DdeltaDvol can evidently assume positive and negative values. It attains its maximal value at St.

Recall that Black and Scholes assumed constant volatility when deriving their formula. Despite being theoretically inconsistent with the Black-Scholes analysis, the measures may well represent good approximations.

Webb has more practical information on DvegaDspot and vanna. What is the DdeltaDvol? Alternatively, this shows that the options vega will decrease by —0.

Figure 5 illustrates DvannaDvol for varying asset price and time to maturity. Figure 6 illustrates the charm value for different values of the underlying asset and different times to maturity. Taleb also points out the importance of taking into account how expected changes in volatility over the given time period affect delta. All partial derivatives with respect to time have the advantage over other Greeks that we know which direction time moves.

We moreover know that time moves at a constant rate. This is in contrast to, for instance, the spot price, volatility, or interest rate. Example Consider a European put option on a futures currently priced at What is the charm of the option?

It still offers some intuition on leverage and risk effects associated with options. Option Beta The elasticity also allows us to easily compute an option's beta. If asset prices follow geometric Brownian motions, the continuous-time capital asset pricing model of Merton holds. To determine the expected return of an option, we need its beta.

The beta of a call is given by Black and Scholes The Sharpe ratio of an option is therefore identical to that of the underlying asset: This relationship indicates the limited usefulness of the Sharpe ratio as a risk-return measure for options.

For instance, shorting a large amount of deep out-of-the-money options may result in a "nice" Sharpe ratio, but, it represents a high-risk strategy. A relevant question is whether you should use the same volatility for all strikes. For instance, deep outof-the-money stock options typically trade for much higher implied volatility than at-the-money options. Using the volatility smile when computing Sharpe ratios for deep out-of-the-money options can make the Sharpe ratio work, slightly better for options.

McDonald offers a more detailed discussion of option Sharpe ratios. Gamma is identical for put and call options: It measures the change in delta for a one-unit change in the price of the underlying asset price.

Figure 7 illustrates the gamma of a call for different values of the underlying asset and different times to maturity. Example Consider a stock option with nine months to expiration. How good is this rule of thumb? In the equity market it is common to use the standard textbook approach to compute gamma, as shown above. Shorting a long-term call put option that later is deep-out-of-themoney in-the-money can blow up the gamma risk limits, even if you actually have close to zero gamma risk.

The high gamma risk for longdated deep-out-of-the-money options typically is only an illusion. This illusion of risk can be avoided by looking at percentage changes in the underlying asset gammaP , as is typically done for FX options.

Gamma Saddle Alexander Adamchuk was the first to make me aware of the fact that gamma has a saddle point. The saddle point is between the two gamma "mountaintops. The gamma increases dramatically when we have a long time to maturity and the asset price is close to zero.

How can the gamma be larger than for an option closer to at-the-money? Is the real gamma risk that big? No, this is in most 4 Described by Adamchuk at the Wilmott forum located at www. That means b must be larger than r-2a 2, or r must be smaller than a2 2b. Gamma is typically defined as the change in delta for a oneunit change in the asset price. When the asset price is close to zero, a one-unit change is naturally enormous in percent of the asset price. In this case it is also highly unlikely that the asset price will change by one dollar in an instant.

In other words, the gamma measurement should be reformulated, as many option systems already have done. It makes far more sense to look at percentage moves in the underlying assets than unit moves.

To compare gamma risk from different underlying assets, one should also adjust for the volatility in the underlying assets. For what time and stock price does gamma have a saddle point, and what is the gamma at this point?

A better measure is to look at percentage changes in delta for percentage changes in the underlying asset gamma percent. This implies that a delta-neutral straddle has maximal ['p.

In most circumstances, measuring the gamma risk as Fp instead of as gamma avoids the illusion of a high gamma risk when the option is far out-of-the-money and the asset price is low.
