Workshop Series: Mitch Warachka

10 November, 2011 - 10:30 to 12:00
Room 430 Joyce Ackroyd Building 37

We develop and test a frog-in-the-pan (FIP) hypothesis that predicts investors are less attentive to information arriving continuously in small amounts than to information with the same cumulative stock price implications arriving in large amounts at discrete timepoints. Intuitively, we hypothesize that a series of gradual frequent changes attracts less attention than infrequent dramatic changes. Consistent with our FIP hypothesis, we find strong evidence that continuous information induces stronger and more persistent return continuation. Over a six-month holding period, momentum decreases monotonically from 8.86% for stocks with continuous information during their formation period to 2.91% for stocks with discrete information but similar cumulative formation-period returns. Analysts forecast errors are also consistent with the FIP hypothesis. Finally, higher media coverage and higher analyst coverage are associated with discrete and continuous information, respectively, while management press releases coincide with continuous good information.
