Ex-dividend day stock behavior

Chen, Hsiu-yen 24 August 2005 (has links)
This study is to examine the phenomenon of stock prices drop around the ex-dividend day in Taiwan. Investors purchasing the security before the ex-dividend date will receive the current dividend, whereas investors purchasing the security on or after this date will not receive the dividend. Consequently, the stock price should fall on the ex-dividend date. In a perfect market, the stock price is expected to fall by the amount of the dividend. I show that share prices do not fall by the full amount of dividend, on average. I focus on falling ratio of stock prices, along with stock return. I also study the factors which may influence stock price behavior and find that the drop of stock price is smaller than the amount of the dividend. That is, the stock price tends to rise on the ex-dividend day. The price drop ratio on the ex-dividend day is higher for firms with greater financial leverage, higher dividend pay out ratio and higher dividend yield. Finally, I also observe that stock return and trading volume increase around the ex-dividend day.

上市公司股利政策改變對股價影響之研究─資訊電子業為例

徐宏良, Hsu, Huna - Liang Unknown Date (has links)
為瞭解上市公司股利政策改變,由股票股利變更為發放現金股利政策之初次宣告效果,本研究以蒐集台灣證券交易所掛牌上市之公司,於2001年1月至2005年12月間,股利政策有變動且首次宣告發放現金股利之資訊電子類股公司,且宣告日前至少有150個交易日資料之公司,共計71個研究樣本。利用事件研究法之市場模式為計算模型,並以一般化之自我相關異質條件變異數模式,分析檢定事件宣告所造成之異常報酬。 本研究以事件研究法,將董事會宣告發放現金股利宣告為事件日(t=0),t=-150~t=-31共120天為估計期,t=-30~t=30共61日為事件期,利用樣本公司之日股價資料,分析異常報酬率。分析方式除針對事件期各日之平均異常報酬率分析外,另開立五個事件窗口,探討各窗口之累積異常報酬率是否顯著,藉以分析事件影響效果。另股利政策改為發放現金股利宣告時,針對當年度與前一年度之股利發放變化程度不同及事件宣告年度市場多、空頭景氣等因素,將樣本分類並分析檢定,在不同條件下之異常報酬率是有否仍顯著。經實證分析,獲得以下結論: 一、公司改變股利政策,由股票股利變更為現金股利的首次宣告事件,對投資人而言,具有公司對未來投資機會認知的資訊內涵。 二、公司改變股利政策由股票股利變更為發放現金股利之首次宣告,投資人對此政策反應抱持正面看法,股價會有兩波上漲趨勢,第二波會有顯著異於零之正異常報酬率。 三、公司改變股利政策,由股票股利變更為現金股利之首次宣告,當年度總發放股利與前一年度比較,股利發放變動大小會影響宣告時市場投資人之投資意願,投資人會隨減少發放股利量而延緩對此政策之正面買進股票反應,事件日後10日內股價會有一波正異常報酬反應。
