Underpricing and Long-Run Performance of Share Issue Privatizations in the Egyptian Stock Market

The phenomenon of underpricing initial public offerings is documented for 53 share issue privatizations in Egypt between 1994 and 1998. Over several intervals (up to five years), I find mixed results: share issue privatizations sustain their positive performance and provide investors with positive abnormal returns over a one-year period, however; my results document negative abnormal returns over three- and five-year horizons. The initial excess returns are determined by ex ante uncertainty and times offer subscribed, whereas the after market abnormal returns over a one-year period are driven by ex ante uncertainty and the price-earnings ratio. However, over three- and five-year periods, abnormal returns are significantly affected by initial excess returns, the price-earnings ratio and, to a lesser extent, times offer subscribed. The empirical findings of this study are consistent with initial public offering markets in which investors are overoptimistic toward the performance of these issues but grow more pessimistic over time
