Abstract: Every year, the companies with favorable perspective are entered into stock exchange through Initial public offering (IPO). This issue is a treat for share of competitors in market and usually, IPO is offered while industry is in top of its valuation, which could be corrected after offering price. In this regard, we study the relationship between IPO and long-term performance of industry, identification and explaining the effective factors. In addition, the relationship of IPS has compared with portfolios of corresponding competitors. In this study, we conclude that the portfolios of competitors had an undesirable performance three years after initial offering. Six effective variables are verified on performance including industry concentration, industry valuation and homogeneity, size of offering, industry operating leverage and industry financial leverage. Undesirable effects of industry is specified when the industry valuation is rather high, industry is in top of valuation or concentration is high in industry, also, when the homogeneity of industry is more, undesirable effect is less.
