Stock Dividend Ex-Day Abnormal Return

Abstract

This study examines the impact of the ex-day of stock dividend on stock return and volume on Borsa Istanbul stock exchange. The data covers 1,220 stock dividends associated with 305 companies over the period 1997-2018. A positive abnormal return and volume is seen around the ex-day of stock dividend. The cumulative average excess return over market return starts to significantly rise ten days before ex-day and reaches its highest level on the ex-day before falling back in the days following. Our findings show that abnormal return around ex-day is strongly associated with stock dividend pay-out ratio, asset size and a company’s market value. The share of listed companies with higher stock dividend pay-out ratio or lower asset size or lower market capitalization, can generate respectively 5.97%, 6.08% and 5.88% abnormal return over market index return.Ovaj rad ispituje utjecaj „ex-day“ dividende na prinos i volumen dionica na burzi Borsa Istanbul. Podaci obuhvaćaju 1.220 dioničkih dividendi povezanih s 305 poduzeća u razdoblju od 1997. do 2018. godine. Pozitivan abnormalan prinos i volumen primjećuju se oko dana kada dionica gubi pravo na dividendu (ex-day). Kumulativni prosječni višak povrata nad tržišnim prinosom počinje značajno rasti deset dana prije ex-day-a i dostiže svoju najveću razinu na ex-day prije nego što se smanji u danima koji slijede. Rezultati pokazuju da je abnormalan prinos oko ex-day-a snažno povezan s omjerom isplate dividendi dionica, veličinom imovine i tržišnom vrijednošću poduzeća. Dionice Borsa Istanbul poduzeća koje kotiraju na burzi s većim omjerom isplate dividendi dionica i one sa skromnom imovinom ili niskom tržišnom kapitalizacijom mogu generirati 5,97%, 6,08% i 5,88% abnormalan povrat u odnosu na tržišni indeks.
