Abstract:
Significantly higher volume in a few day window combined with significantly higher opening may signal a
big up day. Negative relationships between return and volume over a three-day window may signal the
danger of a big down day. Opening prices of all the big down days are significantly higher than the day’s
low and close, and opening prices of all the big up days are significantly lower than the day’s high and
close. The market usually reverses its direction in the day after the big day. A strategy is developed for
excess returns.
