Abstract

This paper is dedicated to study the impact of the stock spams through the analysis of the variations of volumes. We use the methodology of the event studies on a sample of hundred ten firms of penny stock (firms with small size in the American market). Data cover the period of May 2002 to December 2007. The results show a meaningful and positive variations of the volumes essentially observed the first day of the event and to one least degree the following days. The stock spams resuscitated the activity on the market of penny stock.
