Investigations of Initial Public Offering (IPO) in the recent decade have revealed three facts: the IPO cycle, IPO underpricing, and long-run IPO underperformance. This thesis is an empirical contribution to the study of aftermarket performance of IPOs in Egypt from 2005 to end of 2017. The primary objective of this thesis is to determine whether Egyptian IPOs are underpriced in the short run, overpriced in the long run and recognize the foremost influencer of its performance. To evaluate the aftermarket performance, Raw Returns (RR) and Abnormal Returns (AR) methods used to assess short-run performance for the first-day post trading. Also, first month post trading and long-run one-year post trading performance were determined through Buy and Hold Returns (BHR) and Buy and Hold Abnormal Returns (BHAR) relaying on EGX30 index as benchmark Multiple regression is implemented to identify the influencer of the performance on short-run and long run, taking into consideration, offer, firm and market characteristics and their interaction effects. A total of 35 IPO companies went public in the Egyptian exchange from 2005 to 2017 were used in this thesis. Also this thesis used a cross-sectional secondary data obtained from the Egyptian Exchange database and Decypha financial intelligence platform database The findings showed that; IPOs in Egypt are underpriced for the first day equal weighted Row Return by 15.2%, value weight by 10.8%, the first day equal weighted Abnormal Return by 8.2%, value weight by 8.3% in addition to first month equal weighted Buy and Hold Return by 9%, value weighted by 2.3%, first month equal weighted Buy and hold Abnormal Return by 10%, value weighted by 6.4%. Moreover, IPOs in Egypt are underperform the market over a one-year period equal weighted Buy and Hold Return by -9.7%, value weighted by -31%, and Buy and Hold Abnormal Return equal weighted by -20.7%, value weighted by -15.3%
