Price limits and overreaction in the Athens stock exchange

Abstract

In this paper the phenomenon of short-term overreaction and the existence of price limits on the Athens Stock Exchange (ASE) are examined. An 8% price limit was imposed in August 1992 and remained in place until February 2000. The sample consists of 114 shares traded on the ASE for the period 1995–1998. An event study methodology is used in which the event is defined as an increase or decrease in the stock price that activates the price limit for one, two or three days. The findings confirm the occurrence of short-term overreactions on the ASE during the period under investigation.
