A Study of Price-Changed-To-Dividend Ratio on Ex-Dividend Dates: The Case Study of Stock Exchange of Thailand in 2012-2014

Abstract

Most of studies had a similar conclusion that the average stock prices on ex-dividend dates tend to be declined according to the corresponding amount of dividend even though it is the Book Value, BV, which is declined by the amount of dividend.  As many stock traders did not achieve their results based on this conclusion, the research methodology was repeated to assert the myth.  Because none of researches were based on data from the Stock Exchange of Thailand, the research methodology was repeated, only on cash dividends, for years of 2012-2014.  Finally, the results were compared with the previous study and test on their difference among industries and years.  The result showed that the ratio of different countries, e.g. United States, Japan and Thailand are not the same.  However, the result showed no different among industries and years.
