Abstract

We document that media coverage before the IPO day significantly relates to IPO underpricing. The relation is asymmetrical: more media articles are associated with more underpricing when the offer price is revised upwards from the midpoint of the initial filing range, while there is no significant relationship between media coverage and underpricing when the offer price is revised downward. Conditioning on positive price revision, one extra piece of media coverage is associated with about two percentage points greater underpricing. The positive relationship between media coverage and underpricing is stronger when ex ante uncertainty is greater. We fail to find any relation between positive media coverage and IPO firms' long run under-performance. Overall, our findings are consistent with theories of underpricing being driven by the need to compensate investors for information acquisition, but are not consistent with investor sentiment or prospect theory explanations. Moreover, we find that recent stock market returns have significant explanatory power when media attention is omitted from the regressions but are not significant when media attention is included, raising new questions in the debate over partial adjustment to public information for IPOs.
