Media sentiment and IPO underpricing

During an IPO the issuing firm experiences a dramatic visibility shock caused by a large amount of information released to the public. In this context the media play a pivotal role in conveying information to investors who mostly rely on second-hand and simplified news. We argue that the way in which news is presented may shape retail investors' beliefs and in turn drive the demand for share and first-day returns. Based on over 2800 US IPOs and over 27,000 newspaper articles we show that (a) positive tones are positively associated with IPO underpricing; (b) this effect is stronger when news is reported close to the IPO date or (c) by more reputable newspapers.
