The Impact of Private and Public Information on the Trading Behavior in the Egyptian Stock Market

The purpose of this study is to examine The Impact of Private and Public Information on the Trading Behavior in the Egyptian Stock Market, as hypothesized by Daniel et al. (1998). The data covering twelve years from the Egyptian Stock Market, namely the period from 2002 to 2012 on the aggregate market level, is divided into four sub-periods: two tranquil upward-trending periods (2002-2005 and 2005-2008) and two volatile and downward-trending periods (the financial crisis of 2008-2010 and the Egyptian Revolution period of (2010-2012). The study results show that private information shocks have a significant effect on market trading volume, providing evidence of the strong influence of private information on market turnover. This framework not only establishes the presence of an overconfidence bias in the Egyptian Stock Market, but also indicates how the bias changes in response to volatility and dispersion.
