Ownership dispersion, costly information, and IPO underpricing

Article Abstract:

A sample of firm-commitment and best-effort IPO issues from 1977-1988 indicates that the demand of the issuer of an initial public offering (IPO) for expanded ownership dispersion stimulates underpricing/oversubscription, and is assumed to be the for IPO underpricing. Under this assumption, allowing oversubscription leads to broad initial ownership dispersion, which brings about a liquid secondary market for the IPO shares.

Market efficiency, long-term returns, and behavioral finance

Article Abstract:

Stock prices' overreaction to information is as common as underreaction. Such observation shows consistency with the market efficiency hypothesis which claims that anomalies are chance results. A similarity in frequency was also observed between post-event continuation of pre-event abnormal returns and post event reversal. Modification in measurement technique tend to eliminate long-term return anomalies.
