Full textThis thesis is about the comparison of Pricing models for the valuation of American Options. Three classes of numerical approaches are considered. These are Lattice Methods, Analytic Approximations and Monte Carlo Simulation. Methods will be contrasted in terms of accuracy and speed of the computed American option price. One particular method utilises regression when estimating the American option price. For this approach the impact of outliers and multicollinearity is examined and alternative regression models fitted. Monte Carlo Simulation is implemented to calculate early exercise probabilities of American options in the South African market. Results are compared for both call and put options. A test set of 3550 options is simulated with parameters mirroring the South African economy. On this set, the accuracy of all methods is assessed relative to a benchmark price, which is computed by a convergent lattice approach. Finally, American Symmetry is used to evaluate both put and call options.

Full textThis thesis studies American options in an incomplete financial market and in continuous time. It is composed of two parts. In the first part we study a stochastic optimization problem in which a robust convex loss functional is minimized in a space of stochastic integrals. This problem arises when the seller of an American option aims to control the shortfall risk by using a partial hedge. We quantify the shortfall risk through a robust loss functional motivated by an extension of classical expected utility theory due to Gilboa and Schmeidler. In a general semimartingale model we prove the existence of an optimal strategy. Under additional compactness assumptions we show how the robust problem can be reduced to a non-robust optimization problem with respect to a worst-case probability measure. In the second part, we study the notions of the upper and the lower Snell envelope associated to an American option. We construct the envelopes for stable families of equivalent probability measures, the family of local martingale measures being an important special case. We then formulate two robust optimal stopping problems. The stopping problem related to the upper Snell envelope is motivated by the problem of monitoring the risk associated to the buyer’s choice of an exercise time, where the risk is specified by a coherent risk measure. The stopping problem related to the lower Snell envelope is motivated by a robust extension of classical expected utility theory due to Gilboa and Schmeidler. Using martingale methods we show how to construct optimal solutions in continuous time and for a finite horizon.

Full textA maioria das opções negociadas atualmente é do estilo americano, no entanto sua avaliação continua sendo uma tarefa bastante difícil, constituindo-se numa das áreas mais desafiadoras no campo de derivativos financeiros, particularmente quando existem vários fatores afetando o preço da opção. Isso ocorre basicamente porque os métodos de árvores binomiais e diferenças finitas tornam-se impraticáveis na avaliação de opções com mais de três fatores de incerteza. No presente trabalho, faz-se um estudo prévio dos modelos de precificação tradicionais, para posteriormente nos estendermos a modelos mais flexíveis desenvolvidos recentemente baseados em simulações de Monte Carlo e Quase-Monte Carlo, até então considerados inaplicáveis na avaliação de opções americanas. Nesse sentido, pretendemos comprovar a aplicabilidade e versatilidade dos modelos baseados em simulação na avaliação de opções americanas tradicionais ou complexas. Nossa análise baseia-se, sobretudo na ilustração de exemplos práticos, dando especial ênfase à implementação computacional e precisão dos modelos.
The majority of the options negotiated nowadays are of the american style, however its valuation goes on being a very hard job, constituting themselves in one of the most challenging areas in the financial derivative field, particularly when there are several factors affecting the price of the option. It happens basically because the binominal trees and finite differences methods become impracticable in the valuation of options with more than three factors of uncertainty. In this work we are doing a previous study of the traditional methods of american option valuation for later extending this study to more flexible and newly developed models based on simulations of Monte Carlo and Quase-Monte Carlo, which up to the present have been considered inapplicable in the valuation of the american style options. In this sense we intend to prove the applicability and versatility of the models based on simulation in the valuation of traditional and complex american options. Our analysis is, above all based on the illustration of practical examples giving special emphasis to the computational implementation and accuracy of the methods.

Full textOs problemas de apreçamento de opções têm sido um dos principais assuntos de em Matemática Financeira, desde a criação desse conceito nos anos 70. Mais especificamente, as opções americanas são de grande interesse nesta área do conhecimento porque são matematicamente muito mais complexas do que as opções europeias padrão e o modelo de Black-Scholes não fornece, na maioria dos casos, uma fórmula explícita para a determinação do preço deste tipo de opções. Nesta dissertação, mostramos como o estudo de opções americanas conduz à análise de problemas de fronteira livre devido à possibilidade de exercício antecipado, onde nosso principal objetivo é encontrar o preço de exercício ótimo. Também apresentamos a reformulação do problema em termos de um problema de complementaridade linear e de desigualdade variacional parabólica. Além disso, também abordamos a caracterização probabilística das opções americanas com base no conceito de tempos de paragem ótima. Essas formulações, aqui tratadas em termos analíticos ou probabilísticos, podem ser muito úteis na aplicação de métodos numéricos ao problema de precificação de opções do estilo americano, uma vez que, na maioria dos casos, é quase impossível encontrar soluções explícitas. Além disso, utilizamos o Método da Árvore Binomial, que é um método numérico muito simples do ponto de vista matemático, para ilustrar alguns aspectos da teoria estudada ao longo desta tese e para comparar as opções americanas com as opções europeias e bermudas, por meio de alguns exemplos numéricos.
Option pricing problems have been one of the main focuses in the field of Mathematical Finance since the creation of this concept in the 1970s. More specifically, American options are of great interest in this area of knowledge because they are much more complex mathematically than the standard European options and the Black-Scholes model cannot give an explicit formula to value this style options in most cases. In this dissertation, we show how pricing American options leads to free boundary problems because of the possibility of early exercise, where our main goal is to find the optimal exercise price. We also present how to reformulate the problem into a linear complementarity problem and a parabolic variational inequality. Moreover, we also address the probabilistic characterization of American options based on the concept of stopping times. These formulations, here viewed from the analytical and probabilistic point of view, can be very useful for applying numerical methods to the problem of pricing American style options since, in most cases, it is almost impossible to find explicit solutions. Furthermore, we use the Binomial Tree Method, which is a very simple numerical method from the mathematical point of view, to illustrate some aspects of the theory studied throughout this thesis and to compare American options with European and Bermudan Options, by means of a few numerical examples.

Full textO Golfo Pérsico é responsável por aproximadamente trinta por cento da produção mundial de petróleo e detém mais da metade das reservas petrolíferas mundiais. A concentração geográfica do principal recurso enérgico, que alimenta o atual padrão tecnológico mundial, eleva essa região a um ponto de passagem obrigatório nas opções de geopolítica de todos os países do Sistema Internacional. O Golfo Pérsico é uma região de grande instabilidade política, e em menos de trinta anos, enfrentou três guerras internacionais: nos anos oitenta a Guerra Irã- Iraque, nos anos noventa a Guerra do Golfo e, mais recentemente a Invasão Americana ao Iraque. Tais conflitos foram marcados pelo uso, ou pela ameaça de uso, de armas de destruição em massa, e pelas perdas de um contingente imenso das populações dos países em conflito. Esta dissertação analisa a participação americana nestes três conflitos, tomando como referenciais conceitos de geopolítica, uma vez que a especificidade da região exige a retomada dessa disciplina que anda esquecida nas análises internacionais. A geopolítica procura enfatizar o impacto da geografia sobre a política; desta forma, a presença do petróleo no território do Golfo Pérsico, entendido como o Coração Energético Mundial, vai influir decisivamente nas suas relações com os outros Estados do Sistema Internacional. Este estudo analisa as opções de geopolítica dos EUA para a região durante os três conflitos, uma vez que assegurar o acesso às fontes de suprimento energético do Golfo Pérsico é um interesse nacional vital americano.
The Persian Gulf produces about thirty per cent of the world's oil, while holding more than a half of the world's crude oil reserves. The geographical concentration of the most important energy resource that holds the world's contemporary technological standard, puts this region in a very important place for the geopolitical options for all countries in the International System. However, the Persian Gulf is a political unstable region in the world, in less than thirty years was involved in three international wars: in the eighties The Iran-Iraq War, in the nineties The Gulf War and recently The American Invasion of Iraq. These conflicts were known by the use or by the threat of use weapons of mass destruction (WMD), and by the heavy casualties in the countries involved in the war. This dissertation analyses the American participation in these three conflicts taking as referential geopolitical concepts, once the specificity of the region demands the rebirth of this discipline that was so often forgotten in the international analyses. The geopolitics emphasize the geographical impact over politics, so the oil reserves in the territory of the Persian Gulf, the energy heartland, will influence the relationship with the others States in the International System. This study examines the American geopolitical options for the region, once a secure access to Persian Gulf is America's national vital interest.

Full textWe investigate some simulation-based approaches for the valuing of the employee stock options. The mathematical models that deal with valuation of such options include the work of Jennergren and Naeslund [L.P Jennergren and B. Naeslund, A comment on valuation of executive stock options and the FASB proposal, Accounting Review 68 (1993) 179-183]. They used the Black and Scholes [F. Black and M. Scholes, The pricing of options and corporate liabilities, Journal of Political Economy 81(1973) 637-659] and extended partial differential equation for an option that includes the early exercise. Some other major relevant works to this mini thesis are Hemmer et al. [T Hemmer, S. Matsunaga and T Shevlin, The influence of risk diversification on the early exercise of employee stock options by executive officers, Journal of Accounting and Economics 21(1) (1996) 45-68] and Baril et al.

Briggs, Valuing employee stock options under SFAS 123 R using the Black-Scholes-Merton and lattice model approaches, Journal of Accounting Education 25 (1-2) (2007) 88-101]. The underlying assets are studied under the GARCH (generalized autoregressive conditional heteroskedasticity) effects. Particular emphasis is made on the American style employee stock options.

Full textThis thesis investigates the financial decisions through the theory of American and Exotic options. First, the literature on American-style derivatives is surveyed. The pricing of standard American call option in the early exercise premium representation is addressed in order to provide prerequisites for what follows. Second, a new variant of Strangle contracts, called Euro-American or Hybrid Strangles, is introduced and priced. Analytical formulas are provided for the prices of all these option contracts as well as their hedging parameters. A new quadrature is proposed to account for the systems of coupled integral equations that locate the early exercise boundaries. It is shown to be efficient, accurate, and fast for pricing all types of early exercisable strangles and more. Third, we examines the valuation of American Step options contract. The structures of the immediate exercise regions of the various contracts are identified. Typical properties of American vanilla calls are shown to fail in some cases. Formulas for prices and hedging parameters, for the American Step options, are derived. Finally, we consider the valuation of a firm holding simultaneously an option to expand and to abandon productions depending on the state of the market (good or bad) in a real option framework. Optimal decision levels are obtained. Analytical formulas for the firm’s value are provided. Numerical results document the behavior of the firm’s value and optimal exercise boundaries levels

Full textPrissättning av olika finansiella derivat är en viktig del av den finansiella sektorn. För vissa derivat existerar en sluten lösning, men prissättningen av derivat med hög dimensionalitet och av amerikansk stil är fortfarande ett utmanande problem. Detta projekt fokuserar på derivatet som kallas option och särskilt prissättningen av amerikanska korg optioner, dvs optioner som både kan avslutas i förtid och som bygger på flera underliggande tillgångar. För problem med hög dimensionalitet, vilket definitivt är fallet för optioner av amerikansk stil, är Monte Carlo metoder fördelaktiga. I detta examensarbete har därför regressions baserad Monte Carlo använts för att bestämma avslutningsstrategier för optionen. Den välkända minsta kvadrat Monte Carlo (LSM) algoritmen av Longstaff och Schwartz (2001) har implementerats och jämförts med Robust Regression Monte Carlo (RRM) av C.Jonen (2011). Skillnaden mellan metoderna är att robust regression används istället för minsta kvadratmetoden för att beräkna fortsättningsvärden för optioner av amerikansk stil. Eftersom robust regression är mer stabil mot avvikande värden påstår C.Jonen att denna metod ger bättre skattingar av optionspriset. Det var svårt att jämföra teknikerna utan tillvägagångssättet med dualitet av Andersen och Broadie (2004) därför lades denna metod till. De numeriska testerna indikerar då att avslutningsstrategin som bestämts med RRM producerar en högre undre gräns och en snävare övre gräns jämfört med LSM. Skillnaden mellan övre och undre gränsen kunde vara upp till 4 gånger mindre med RRM. Importance sampling och Quasi Monte Carlo har också använts för att reducera variansen i skattningen av optionspriset och för att påskynda konvergenshastigheten.

We consider in this thesis the problem of pricing American Put Options in a model-free framework where we do not make any assumptions about the price dynamics of the underlying except those implied by the no-arbitrage conditions. Our goal is to obtain bounds on the price of an American put option with a given strike and maturity directly from the prices of other American put options with the same maturity but different strikes and the current price of the underlying. We proceed by first investigating the structural properties of the price curve of American Put Options of a fixed maturity and derive necessary and sufficient conditions that strike - price pairs of these options must satisfy in order to exclude arbitrage. Using these conditions, we can find tight bounds on the price of the option of interest by solving a very tractable Linear Programming Problem. We then apply the methods developed to real market data. We observe that the quality of bounds that we obtain compares well with the quoted bid-ask spreads in most cases.

This paper extends the forward Monte Carlo (FMC) method, which have been developed for the basic types of American options, to the valuation of two-asset American rainbow options. The main advantage of this method is that it does not use backward induction as required by other methods. Instead, the proposed approach relies on a wise determination about whether a pair of simulated stock prices has entered the exercise region. A series of numerical experiments are provided to compare the performance with the binomial tree model and least squares method and demonstrate the efficiency of the forward methods.

Full textThe constant elasticity of variance (CEV) model is a practical approach to option pricing by fitting to the implied volatility skew. Its application to American-style derivatives, however, poses analytical and numerical challenges. By taking the Laplace Carson transform (LCT) to the free-boundary value problem characterizing the option value function and the early exercise boundary, the analytical result involves confluent hyper-geometric functions. Thus, the numerical computation could be unstable and inefficient for certain set of parameter values. We solve this problem by an asymptotic approach to the American option pricing problem under the CEV model. We demonstrate the use of the proposed approach using perpetual and finite-time American puts.
