The Effect Of Sustainability Index Inclusion On Equity Fund Allocation Evidence From Thailand, Tanakorn Makarabhiromya
The Effect Of Sustainability Index Inclusion On Equity Fund Allocation Evidence From Thailand, Tanakorn Makarabhiromya
Chulalongkorn University Theses and Dissertations (Chula ETD)
The concept of sustainability index has been accepted widely in the global investment context. However, sustainable investments are relatively underexplored in an emerging market as in Thailand. This study analyzes the relationship between corporate sustainability performance (proxy by announcement events of the Stock Exchange of Thailand Sustainability Index SETTHSI) and institutional investors’ awareness toward sustainability investment. An event studies on index announcement are applied to analyze the short-term effect from investors in stock market. The results indicate that there is only weak evidence that inclusion into the sustainability index has a positive impact to cumulative abnormal returns during release-related period, …
A Pair Trading Using Reinforcement Learning And Wavelet Decomposition, Panudate Nithinon
A Pair Trading Using Reinforcement Learning And Wavelet Decomposition, Panudate Nithinon
Chulalongkorn University Theses and Dissertations (Chula ETD)
In this study, we propose a trading optimization methodology for the pair trading strategy. The Johansen cointegration test and the correlation measure are used for pair selection. We apply Deep-Q-network (DQN) technique in which the trainable reinforcement learning agent is designed to directly control the trading positions. The maximum overlap discrete wavelet transformation (MODWT) algorithm is used for generating the trading signal from the spread time series. Wavelet signal preprocessing is used to extract the original time series into cyclic time series components and long-term behavior components. Based on the in-sample performance this trading model successfully solves a profit maximizing …
Forecasting Stock Volatility With Neural Network On Time Varying Transition Probability, Wasit Norakarntiansin
Forecasting Stock Volatility With Neural Network On Time Varying Transition Probability, Wasit Norakarntiansin
Chulalongkorn University Theses and Dissertations (Chula ETD)
Forecasting volatilities of financial security returns are important for many financial applications e.g., portfolio investment construction, risk management and trading strategy. The GARCH model has long been refined to capture the true dynamic of volatility on a security return. By applying the Markov switching to the GARCH model, the source of the temporary high volatility and high persistence of a shock to the volatility can be captured. In this study, we refine the Markov switching GARCH model further by applying the notion of the neural network to approximate the time varying transition probabilities. We aim to achieve a model that …

Flow-Performance Relationship In Defi Yield Aggregator, Apisara Pornprasith
Flow-Performance Relationship In Defi Yield Aggregator, Apisara Pornprasith
Chulalongkorn University Theses and Dissertations (Chula ETD)
Decentralized Finance (DeFi) is a new financial infrastructure with applications similar to traditional financial products, such as exchange, lending, derivatives, and asset management. This paper empirically investigates Yearn finance, one of the fastest-growing and largest in DeFi yield aggregator protocols for on-chain asset management, to demonstrate the flow-performance relationship and compare it with mutual funds in traditional finance. According to the findings, there is a positive non-linear relationship between fund flows and recent performance for using stablecoin deposited. In contrast, we cannot find this relationship for using cryptocurrency. Then, we look further into stablecoin holder behaviour and our findings show …

The Impact Of Government Response To Covid-19 On Stock Return Predictability, Disayadej Dangdej
Chulalongkorn University Theses and Dissertations (Chula ETD)
Recession is known to cause an increase in stock return predictability. The COVID-19 pandemics had not only resulted in sickness and loss of life but also plunged global economy into recession prompting governments to come up with measures to combat the disease. This paper first confirms that return predictability increased due the spread of COVID-19 using data from 41 countries on variations of popular predictors. Furthermore, it shows that government responses to COVID-19 alleviated the pandemic, the recession and reduced the return predictability with varying impact for different government measures. However, cases and deaths from COVID-19 which should have intensified …
Application Of Fractional Exponential Feature To Garch Model Variants For Improvement In Value-At-Risk Prediction, Chanet Saisatian
Application Of Fractional Exponential Feature To Garch Model Variants For Improvement In Value-At-Risk Prediction, Chanet Saisatian
Chulalongkorn University Theses and Dissertations (Chula ETD)
This research studies about using GARCH model variants as a parametric way in estimation and prediction of daily Value-at-Risk (VaR), one of famous risk measurement especially in financial world. To cope with various stylized facts on market’s volatility, two mixed GARCH models are proposed in this research: HY-GJR-GARCH model, the hybrid between hyperbolic GARCH (HYGARCH) and GJR-GARCH models, and HY-MS-GARCH model as the amalgam between HYGARCH and Markov switching GARCH (MSGARCH) models. These mixed models, along with rich mathematical formulations and benefits from their base models, are expected that their performance in predicting daily VaR is advanced against the performance …

Why Is The Third Principal Component Of The Yield Curve Important: A Point Of View From Reverse Stress Test On Credit Portfolio, Phanuwat Ritpornnarong
Chulalongkorn University Theses and Dissertations (Chula ETD)
The focus of this study is to analyze the shape of the yield curve on credit portfolios during crises, specifically those that are exposed to both interest rate and credit risks. To achieve this, We utilized a reverse stress test (RST) and macroeconomic measures (such as GDP and U.S risk-free yields) from the period of 1981 to 2014 to estimate mathematical models. We then utilized a Monte Carlo simulation to determine the most likely scenario for the measures if the portfolio value reaches a pre-specified threshold. The researchers discovered that the shape of the stressed yield curves varied depending on …
Accrual-Based Earnings Management And Real Earnings Management Around Two Key Corporate Governance Regulatory Regime Changes In Thailand, Noor Nayeem Hasnat Farhan
Accrual-Based Earnings Management And Real Earnings Management Around Two Key Corporate Governance Regulatory Regime Changes In Thailand, Noor Nayeem Hasnat Farhan
Chulalongkorn University Theses and Dissertations (Chula ETD)
Two major corporate governance-related regulatory changes, one in 1999 and one in 2008, were implemented as a means to increase the independence of boards of directors of public companies in Thailand. I study whether each of these regulatory changes affects the degree of and leads to substitution of accrual-based earnings management (AEM) and real earnings management (REM), plus the effect of family ownership on the type and degree of earning management. The outcomes of the two regulatory changes are different with respect to earnings management. Univariate tests suggest no change in the levels of AEM and REM for the 1999 …

Is Currency Risk Priced In The Stock Return - Evidence From Aec Markets, Viriyah Vorasitchai
Chulalongkorn University Theses and Dissertations (Chula ETD)
When investors from different countries invest abroad in the same destination country and same asset is invested, they may achieve different foreign asset return or value after converting back to the home currency in each country, in other words, the value of such investment and its return could differ from what they retain in the that foreign currency. This phenomenon leads to the risk called “currency risk”. The currency risk could also be seen in several different ways such as economic risk, transaction risk as so on. Considering the value of the asset return after converting back to home currency, …
The Evidence Of The Beta Anomaly In The European Reit Market, Nutpapol Tantratananuwat
The Evidence Of The Beta Anomaly In The European Reit Market, Nutpapol Tantratananuwat
Chulalongkorn University Theses and Dissertations (Chula ETD)
This paper finds empirical evidence of the beta anomaly in the European REIT market in the period 2012 – 2021. The alpha of a low minus high beta strategy is positive and statistically significant which can interpret that the low beta REITs have a higher risk-adjusted return than high beta REITs. To examine the explanation behind the beta anomaly, the controlling variables which may cause the beta anomaly including the lottery-like stock return factor, the skewness factor, and the institutional ownership factor are added into the Fama-French 3-factor model. For the result, only the institutional ownership factor which refers to …

The Effect Of Female Board On Firm Value Evidence From The Asia Pacific, Tanyatorn Kulalert
The Effect Of Female Board On Firm Value Evidence From The Asia Pacific, Tanyatorn Kulalert
Chulalongkorn University Theses and Dissertations (Chula ETD)
This paper examines the relationship between board gender diversity and firm value of companies in the Asia-Pacific from 2011 to 2020. Fixed effects and two-stage least squares are employed to deal with endogeneity. We find that increasing female directors to the board has a positive and significant effect on firm value as measured by Tobin’s Q. The result suggests that independent directors have a positive and significant impact on firm value. However, when the board is composed of independent directors, appointing female directors decreases the firm's value owing to over monitoring. Furthermore, the positive effect of female directors appears to …

How Sensitive Are Ipos To The Fear Of The Covid-19 Pandemic In Emerging Markets?, Kavisara Vachekrilas
Chulalongkorn University Theses and Dissertations (Chula ETD)
This study investigates the relationship between COVID-19-related pandemic fear and the short-term performance of initial public offerings in emerging markets. This paper investigates whether the short-term fear of COVID-19 continues to influence post-IPO performance. In doing so, the fundamental methodology is cross-sectional ordinary least squares (OLS) regression and numerous variables are included to the model as control variables. The results show that whether looking at the first-day trading price of an IPO or the subsequent trading prices, the effect of pandemic fear (GFI, RCI and RDI) was positive. However, results were somewhat different for HighGFI, which was a dummy variable …

Is Thai Baht A Safe Haven Currency During The Covid-19 Pandemics, Nanapat Chaochavanil
Chulalongkorn University Theses and Dissertations (Chula ETD)
This paper empirically investigates whether or not Thai Baht (THB) is actually one of the safe haven currencies. Moreover, we also extend analysis to see if its safe haven pattern is persistent during the COVID-19 pandemic. We are not only study for THB, but also take into account other traditional well known safe- haven currencies namely U.S. Dollar (USD), British pound sterling (GBP), Euro (EUR), Swiss Franc (CHF) and Japanese Yen (JPY). By investigating between 2010 - 2019, our results do not support the idea that THB is a safe haven currency. Nevertheless, this paper found that for other well-known …

Does Size Really Matter? In Mergers Of Equals : An Event Study, Piyamart Srithanomwong
Chulalongkorn University Theses and Dissertations (Chula ETD)
This research presents empirical studies on the impact of mergers of equals on shareholders’ wealth. Due to integration problems between combining corporations, Daimler-Chrysler merger failures caused the corporate sector to think that mergers of equals erode shareholder wealth. However, it is based on a small proportion of MOE transactions, and there is no empirical evidence on the shareholder’s return on the announcement date implications of MOEs related to the size of the merger. I provide this research knowledge for the shareholder wealth at the announcement date for the implications of MOEs related to the size effect of the merger. Furthermore, …

Chulalongkorn University Theses and Dissertations (Chula ETD)
This study examines how Thailand GDP announcement surprise affects AEC stock markets which are Thailand, Indonesia, Malaysia, Singapore, Philippines, and Vietnam. In the sample of 44 GDP announcements in Thailand during 2009-2019, our result suggests that there is no impact to AEC stock markets on GDP announcement date. However, we find pre-and post- GDP announcement effect spillover to other countries in AEC. In addition, the direction of Thailand GDP announcement has no reaction on abnormal return on AEC stock exchanges. In contrast, our findings report the influence of macroeconomic conditions in Thailand on the abnormal return in Malaysia, Singapore, and …
