ItemAbnormal return on stock split-revisiting the evidence of Thailand during 2009-2018(Assumption University Press, 2020) Sedthaporn Tosiriwatanapong ; Thananporn Sethjinda ; Nopphon TangjitpromAn abnormal return on the stock split is one of the most prominent debates in the finance industry. Positive signaling and optimal trading range hypotheses are underlying principles that are commonly used to describe a positive market reaction to the stocksplit. This research paper focuses specifically on the market’s reactions by the announcement date of the stock split, applying firm size and price range to explore insightful connections. The samples are listed companies in the Stock Exchange of Thailand(MAI excluded) with a stock split from January 1, 2009, to December 31, 2018, aiming to capture data in all economic cycles. To examine positive abnormal returns around announcement date, the event-study-methodology is applied. The study indicates that average abnormal return (AAR) and cumulative average abnormal return (CAAR) are significantly positive during the announcement. Applying firm size in the study, the market tends to react more positively to small-size firms, likewise, low-price. The pieces ofevidence indicated that stocks responded more positively by reason of consciously or subconsciously anticipation to post-splits. The investors are able to apply the rationales and logic behind this corporate action to distinguish between fundamental changes and expectations for their investment decisions in financial markets.
ItemCorporate Governance, Violations and Market Reactions( 2013) Visit PhunnarungsiWe test the relation between firm-level corporate governance and the market reaction to announcements of violations of rules and regulations by Thai listed firms. We find no significant difference in market reaction when firms with high and low governance scores commit violations. We do find a larger negative abnormal return when firms with low past violation records violate the rules. The market reaction is especially strong, − 8.1% on average, when firms with low past violations and low governance scores commit violations. The evidence suggests that investors rely on a combination of observed behavior (violations) and the firm's formal governance policies to learn about the firm's true governance practices.
