This study mon stock prices around
ex-dividend dates. Such price data usually contain
a mixture of observations—some wlth and some
without arbitrageurs and/or dividend capturers
active. Our theory predicts that such mixing will
result in a nonlinear relation between percentage
price drop and dividend yield—not monly
assumed linear relation. This prediction and
another important prediction of theory are sup-
ported empirically. In a variety of tests, marginal
price drop is not significantly different from the
dividend amount. Thus, over the last several
decades, one-for-one marginal price drop has been
an excellent (average) rule of thumb.
The behavior of stock prices around ex-dividend dates
is of interest to finance scholars for several reasons. It
