P. Hietala et M. Keloharju, THE EX-DIVIDEND DAY BEHAVIOR OF FINNISH RESTRICTED AND UNRESTRICTED SHARES, Applied economics letters, 2(12), 1995, pp. 467-468
We analyse the ex-dividend day behaviour of two classes of shares whos
e trading is potentially dominated by investors under different tax re
gimes because of foreign ownership restrictions. Our results provide e
vidence in favour of the hypothesis that long-term investors are the m
arginal investors that determine the stock prices around the ex-divide
nd day, and against the hypothesis that short-term trading is the driv
ing force behind equilibrium ex-dividend ratios.
