The present study is conducted to see how an IPO event affects the existing firm's performance within the same industry. For this purpose, 88 IPO firms were examined from Pakistan Stock Exchange (PSX) from 1998-2016. IPO is examined from three major perspectives IPO proceeds, initial returns and time Lag between IPO listing date and IPO subscription. The study uses Buy and Hold Abnormal Returns (BHAR) and Cumulative Abnormal Returns (CAR) to calculate competitor's abnormal returns. To calculate the operating performance of competitors, the Wilcoxon significance test was applied. IPO intra-industry effects are significant in the long run, whereas insignificant results are shown in the short run. In addition, IPO proceeds and abnormal returns are significant but negatively related to competitors' stock returns (long term). Moreover, Herfindahl Hirschman Index (HHI) finds IPO improves competitiveness in the industry environment. This present study is an important one from an emerging economy perspective.
