This paper presents the wide analysis of the profitability factors of dividend capture strategy on public pharmaceutical companies within a five-year period after the global financial crisis 2008. We investigate the abnormal return and trading volumes with event study, and the effect of price changes around the ex-dividend date under the influence of various factors. Our findings suggest that there are no abnormal trading volumes on both the $-1$ day of the event window and the day of the event on a subsample of companies that do not declare a dividend before the register close date. We confirm the negative stock yield on the ex-dividend day in most markets. We further confirm the tax hypothesis explaining the behavior of the share price and note the specific behavior of stock prices in the ex-dividend date for companies that do not disclose information on future payments (Japan and South Korea) and on emerging markets. The positive average cumulative abnormal return is statistically significant only for companies with a share of R&D/Total revenue $<$3%. For companies with a value of more than 3%, the return is negative. An anomaly in the pharmaceutical stock market behavior in the ex-dividend date for 2016 is documented in our paper. A statistically significant price increase is registered both without taking into account the general market behavior, and taking into account market and individual expected return for each share of the sample. The cumulative abnormal returns are greater for pharma companies with a total enterprise value more than $1 billion, except for 2016.

This paper extends ISO certification research by investigating whether a stock value is influenced by the announcement of its ISO registration with respect to the firm size, industry, and ISO standard series on the Taiwan Stock Exchange. The results show that receiving ISO registration influences abnormal returns. The market reacts favorably to both small and large firms but has no reaction to medium firms in terms of a firm's capital. We also observe significant positive market reaction for Plastics and Textiles. A beneficial implication is that investors may benefit more from their investment endeavors if they can properly examine the specific effects.

This study analyzes market reactions to firms’ “NFT” or “Non-Fungible Token” disclosures filed with the SEC. The analysis distinguishes “Clear” disclosures, indicating actual NFT engagement, from “Vague” ones, referring to vague future intentions. Both types exhibit similar non-significant CAAR behavior upon announcement, followed by a significant decline. Positive cash flow firms experience initial positive CAAR, reversing by day 4. Segmenting by traits shows varied CAAR patterns, but overall, the study suggests skepticism toward NFTs. Firms in or entering this space face consistent negative CAAR over 30 days post-publication, indicating market mistrust.

In this chapter, we show how the t-statistics is used in testing whether systematic corporate financial events, such as dividend payout, bonus issue, earnings announcements, and so on, affect the market prices of the corresponding stocks.
