Option Pricing Using Local Volatility Function: How To Specify Its Knots?, Wisuth Raweerojthanatt
Option Pricing Using Local Volatility Function: How To Specify Its Knots?, Wisuth Raweerojthanatt
Chulalongkorn University Theses and Dissertations (Chula ETD)
European options of an asset are priced following a continuous 1-factor diffusion model and the generalized Black-Scholes equation. Volatility knots are determined by many specifications that are the number and the location of knots at any stock price and time to expiration. Considering the volatility knots as a set of decision variables, we can approximate the local volatility function with a bicubic spline function to compute option values fitted to a finite set of market data by solving a constrained nonlinear optimization problem. With the real market data of SET50 Index options, pricing accuracy of different knots’ specifications are demonstrated. …

The Hybrid Pareto Distribution, Implied Risk-Neutral Density And Option Pricing, Purin Luanloy
The Hybrid Pareto Distribution, Implied Risk-Neutral Density And Option Pricing, Purin Luanloy
Chulalongkorn University Theses and Dissertations (Chula ETD)
This paper aims to develop a new European option pricing model based on the Extreme Value Theory (EVT). We assume that, in the risk-neutral probability measure, simple negative returns of the S&P500 index follow the Hybrid Pareto (HP) distribution. Then, we derive closed-form pricing formulas for call and put options according to the risk-neutral pricing method. Additionally, we assume that the distribution has a fat tail. Our study’s benchmark model is the Generalized Extreme Value (GEV) model proposed by Markose and Alenton (2011). We estimate model parameters by minimizing the root-mean-square error. The results show that the HP model provides …

The study uses simulation method, developing on real-business-cycle theory to generate artificial business cycle moments and impulse response function. For the result, it considers news …
Market Liquidity And Mutual Fund Performance During Financial Crisis, Matina O-Warinrat
Market Liquidity And Mutual Fund Performance During Financial Crisis, Matina O-Warinrat
Chulalongkorn University Theses and Dissertations (Chula ETD)
Market illiquidity influences mutual fund performance differently between crisis and non-crisis period. A significant drop in market liquidity makes investors panic leading to the early and large redemption. Fund managers have to liquidate the portfolio putting pressure on the asset prices, so the underperformance of mutual fund is recognized in non-crisis period. However, the result of illiquidity is different during crisis. The total effect of market illiquidity is positively related to all fund classes. This could then be interpreted as the evidence of management skills, market-timing and volatility-timing skills in fund managers to provide superior fund performance. Moreover, the further …
Intangible Capital, Q Theory Of Investment And Measurement Of Profitability, Kunyamas Nithipaisal
Intangible Capital, Q Theory Of Investment And Measurement Of Profitability, Kunyamas Nithipaisal
Chulalongkorn University Theses and Dissertations (Chula ETD)
Contribution of intangible capital has been a notable factor of today’s economy. However, previous literatures mainly focus on outcomes of physical investment through classical theory of investment and financial ratios, so this paper aims to explain effects of intangible capital in two major points. Firstly, new Tobin’s q proxy, which includes intangible capital, is reexamined regarding its explanation of total investment; new Tobin’s q, thus, explains investment opportunities better in firms and years with greater intangible capital. Secondly, financial ratios are rearranged by taking intangible capital into consideration. As a result, firms with more intangible capital do not generate higher …

A Neural Network-Based Method For Solving A Dynamic Investment And Consumption Problem With Transaction Costs And Stochastic Volatility, Kittipong Noonoi
Chulalongkorn University Theses and Dissertations (Chula ETD)
Optimal investment and consumption problem with proportional transaction costs known as Davis \& Norman problem is a challenging portfolio free-boundary problem to solve. According to the HJB equation, see Davis and Norman (1990), there are three optimal regions i.e. no-trade region, buy region, and sell region in which different actions are prescribed. However, the two boundaries separating the three regions are unknown and it is crucial to discover them in order to obtain the optimal policy. Nonetheless, under a special class of model in which the excess return of stock is assumed to be positively linear in variance reflecting the …
A Reinforcement Learning Model For Lending Problems With Limited Budget And Insufficient Data, Radaporn Autravisittikul
A Reinforcement Learning Model For Lending Problems With Limited Budget And Insufficient Data, Radaporn Autravisittikul
Chulalongkorn University Theses and Dissertations (Chula ETD)
Traditional lending policy requires sufficient data for making lending decisions, therefore, some small companies could not access to the fund. In this study, we propose a decision making model that can decide whether to accept or reject a sequence of unfamiliar loan applications while having a limited budget. Our model does not have any knowledge about the incoming loans, therefore, it can predict the default probability with low accuracy at the beginning. The model can learn by observing the outcomes of the accepted loans. The model's budget increases every time the model accepts a fully paid loan and decreases when …

Equity Term Structure Of Property Funds And Reits In Thailand, Chenchai Chotchuangnava
Equity Term Structure Of Property Funds And Reits In Thailand, Chenchai Chotchuangnava
Chulalongkorn University Theses and Dissertations (Chula ETD)
The equity term structure of property funds and REITs in Thailand is upward-sloping. This result contradicts with various studies suggesting that the term structure of risk premia is decreasing. A tenet of those studies is that, by holding long-term equity, investors are willing to forego a part of the compensation to avoid immediate risks which seems to be reverse for property funds and REITs in Thailand. There is evidence that the correlation between size and return is positive. Unlike U.S. REIT, the momentum factor has no application to explain the difference in excess returns. High turnover property funds and REITs …

Shareholder Involvement And M&A Announcement Returns : Evidence From Thailand, Chanon Thanaphumphong
Chulalongkorn University Theses and Dissertations (Chula ETD)
How corporate governance mechanism helps prevent underperformance of acquiring firms is controversial, especially with little evidence in Asia-Pacific literature. I examined how shareholder involvement by means of mandatory shareholder voting (class 1) and required information disclosure (class 2) under the SET’s Acquisition and Disposition Rule affected the market reaction on mergers and acquisitions. I did not find significant differences in the CARs among transaction classes with different degree of shareholder involvement. The results were consistent both in univariate and multivariate analysis which deal- and firm-level factors are controlled. I investigated further and found that concentrated ownership in Thai firms did …

The Flow-Performance Relationship Of Etfs In International Market, Thaweeporn Krailaksanawarapar
Chulalongkorn University Theses and Dissertations (Chula ETD)
This paper uses sample from 15 countries from different regions around the world to examine how past performance of exchange-traded funds (ETFs) impact on their fund flow in the following period. Piecewise-linear regression following (Sirri & Tufano, 1998) which allow past performance to be non-linear are employed in the model to examine the different sensitivity of past performance ranking to flow. The evidence confirms that past bad-performing ETFs associate with outflow and past good-performing ETFs associate with inflow in the following period. Furthermore, I also find that investors are more sensitive to bad performers than good performers suggesting that there …

Characteristic Approach To High Risk Low Return Puzzle In Set, Putchara Poomgumarn
Chulalongkorn University Theses and Dissertations (Chula ETD)
Theoretically investing in high risk asset generates high return. However, actual payoff in market is in the opposite side. In several empirical studies documented high risk stocks paid low return even lower than the portfolio of the lowest volatile stocks. I examine whether the cause of this anomaly is the lottery stocks. Lottery stocks which are low price, high skewness and high kurtosis might be desired by many investors even institutional investors. The assumption is that this high demand of lottery stocks might push the price up and cause low average return finally. Therefore, I set up the hypothesis these …
