Barrier Option Pricing under SABR Model Using Monte Carlo MethodsHu, Junling 02 May 2013 (has links)
The project investigates the prices of barrier options from the constant underlying volatility in the Black-Scholes model to stochastic volatility model in SABR framework. The constant volatility assumption in derivative pricing is not able to capture the dynamics of volatility. In order to resolve the shortcomings of the Black-Scholes model, it becomes necessary to find a model that reproduces the smile effect of the volatility. To model the volatility more accurately, we look into the recently developed SABR model which is widely used by practitioners in the financial industry. Pricing a barrier option whose payoff to be path dependent intrigued us to find a proper numerical method to approximate its price. We discuss the basic sampling methods of Monte Carlo and several popular variance reduction techniques. Then, we apply Monte Carlo methods to simulate the price of the down-and-out put barrier options under the Black-Scholes model and the SABR model as well as compare the features of these two models.

The Impact and Pricing Formula of the National Finance Stabilization Fund: Application of the Barrier OptionChan, Chieh-chung 07 August 2006 (has links)
In the first part of this article, we discuss the time and the probability for the barrier option to become effective, and then employ the risk neutral assumption to derive the pricing formula of the barrier option. Our pricing formula is a closed form solution, and we may calculate the price of the barrier option without considering the Binomial tree of the underlying asset. We also calculate the traditional option price by our pricing formula, and compare the result to the value that is calculated by Binomial pricing formula. Both of them give the same value about the tradition option, and thus we may regard the tradition option as the special case of the barrier option. In the second part of this article, we employ the pricing formula of the barrier to derive the value of the National Finance Stabilization Fund, and then analyze the impact of the NFSF to the market. Our results reveal that when the benchmark market is not shifted by the bad news, then the NFSF may advance and stabilize the stock price index. In fact, many new style derivatives have the characteristics like barrier option, for example, a convertible bond with forced convert clause, which is a up-and-out call. Other course like bankruptcy costs, agency problems, and contingent liabilities etc, which can all be solved by the pricing formula in our discussion. We hope that results and the process in this article are helpful in solving above questions.

A comparison of numerical methods for pricing single and double barrier optionsYehya, Mhd Rashid January 2021 (has links)
Barrier options are the most popular and traded derivatives in the financial market because of their lower prices. Many studies have been conducted to develop the methods of pricing barrier options. Barrier option prices can be calculated using the classical binomial tree method, but it is time-consuming when we have a large number of time periods. Muroi and Yamada have developed a new fast algorithm to obtain the prices of barrier options by using the spectral expansion approach. We implement and check this algorithm by doing more extensive numerical experimental studies and showing that the same prices calculated using the binomial tree method can also be obtained using the spectral binomial tree approach with a higher computational speed.

Pricing outside barrier options when the monitoring of the barrier starts at a hitting timeMofokeng, Jacob Moletsane 02 1900 (has links)
This dissertation studies the pricing of Outside barrier call options, when their activation starts at a
hitting time. The pricing of Outside barrier options when their activation starts at time zero, and the
pricing of standard barrier options when their activation starts at a hitting time of a pre speci ed
barrier level, have been studied previously (see [21], [24]).
The new work that this dissertation will do is to price Outside barrier call options, where they will be
activated when the triggering asset crosses or hits a pre speci ed barrier level, and also the pricing of
Outside barrier call options where they will be activated when the triggering asset crosses or hits a
sequence of two pre specifed barrier levels. Closed form solutions are derived using Girsanov's theorem
and the re
ection principle. Existing results are derived from the new results, and properties of the new
results are illustrated numerically and discussed. / Mathematical Sciences / M. Sc. (Applied Mathematics)

結構型債券之評價與分析謝嫚綺, Hsieh, Man-Chi Unknown Date (has links)
本文研究最近在市面上常見的結構型債券,利用Martingale評價方法以及數值方法求出結構型商品的理論價格以及利用情境分析來推估期末可能的報酬,提供投資人與券商對於結構型商品特性與風險的了解,並且提供發行商避險的參考。然而結構型商品的複雜程度往往是來自於隱含的新奇選擇權,本文亦分析商品內含的新奇選擇權,使得投資人更了解結構型商品的組成,發行商也可藉以由組成的概念進而設計新的結構型商品。

目標贖回雪球型利率連動債與雙匯率連動債之評價與分析陳紋卿 Unknown Date (has links)
本文主要評價與分析兩種結構型債券:一為目標贖回雪球型利率連動債、一為雙匯率連動債。
第一個商品利率連動債券為十年期、每季付息債券,其指標利率為三個月期LIBOR利率。本文以BGM市場模型進行評價,同時考慮40個遠期三個月期LIBOR利率的動態過程,而每個動態過程之間的相關係數為一40維度的方陣,為了加速計算速度採用Weigel(2004)運用線性代數降秩的方法,使原本相關係數矩陣由「秩40」降為「秩11」後,不僅可以加快運算速度又不會使原本相關係數矩陣失真。以蒙地卡羅模擬利率路徑評價後並進行敏感性分析。
第二個商品雙匯率連動債券連結到兩個匯率指標:歐元兌日圓及美元兌新台幣。其中連結歐元兌日圓匯率的報酬型態為雙界限出局二元選擇權,而連結美元兌新台幣匯率的報酬型態為下出界選擇權。本文利用Ritchken(1995)三元樹分別建構兩個匯率界限選擇權的評價,並發現歐元兌日圓匯率界限選擇權的價值佔債券面額的比例極小,故之後只針對美元兌新台幣匯率界限選擇權進行敏感性分析。
