Are Short Sellers Equally Informed? Evidence From The Us. Credit Rating Announcements, Omtong Kasemsant

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study uses credit rating and daily short sale data of firms listed in NYSE from January 2015 to December 2021 to examine whether there is informed trading. Although post-announcement abnormal return is negatively correlated with abnormal short volume, no evidence of informed short selling is found. Higher level of pre-announcement abnormal short selling is positively correlated to default risk and also explained by the incentives of short sellers to short more when past returns are negative. Furthermore, increase in short selling that is preceded by credit watch placement is more pronounced before credit rating downgrades. Moreover, the evidence shows …

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 …

This research explores the effect of government's COVID-19 response policy on stock market volatility. We explain the stock market volatility dynamics via the index that measures the strict level of government response’s policy to COVID-19. Using EGARCH (1,1) model to identify stock market volatility from daily stock market return of 68 countries and apply the Arellano–Bond two-step system GMM estimator for dynamic panel data analysis, we found that the stock market volatility in the COVID-19 period can be reduced by the government policy response to COVID-19. Furthermore, after dividing the index into 3 types, all types of policy also reduce …

In this research, we study an announcement effect of Facebook Inc.’s rebranding to Meta Platform Inc. in October 2021, as a flagship event that sheds spotlight to the metaverse business, on 50 metaverse-related cryptographic tokens. Using Google’s CausalImpact package in R with historical daily returns within -30,7 windows, the model expects a 11.80% counterfactual CAR but the actual CAR is 69.20%, indicating a 57.40% absolute effect of this announcement on aggregate metaverse tokens at 99% significant level. We also further regress five factors, namely game-fi, marketplace, holders, illiquidity, and VC factor on the post-announcement CAR. However, the result is sparse. …

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 …

Mutual Fund Performance Evaluation With Active Peer Benchmarks Of Domestic Equity Funds In Thailand, Pornthip Supasinthanaphat

Chulalongkorn University Theses and Dissertations (Chula ETD)

We use the active peer benchmarks (APB) methodology suggested by Hunter et al. (2014) to capture commonalities or common idiosyncratic noise in fund strategies. These commonalities cannot be captured by the Carhart 4-factor model and it also decreases the accuracy in fund performance evaluation. Firstly, we examine the efficiency of the APB methodology compared with the Carhart 4-factor model. Then we also use the APB methodology to evaluate the performance of actively managed Thai open-end domestic equity funds from January 2006 through December 2020. In the APB methodology, we focus on two dimensions: fund returns and the fund’s investment objectives. …
