Allocations, Adverse Selection and Cascades in IPOs Evidence from Israel

This paper examines three theories of IPO underpricing, using data from Israel where the allocations to subscribers are equally prorated and publicly known. Rock’s (1986) theory of adverse selection is supported: subscribers receive greater allocations in overpriced IPOs. And, while the average IPO excess return is 12%, the simulated allocation weighted return to uninformed investors is slightly negative. Welch’s (1992) theory of information cascades is supported by the pattern of allocations: demand is either extremely high or there is undersubscription, with very few cases in between. Also supported is the proposition that underpricing is a means to increase ownership dispersion

Metastatic Ewing's sarcoma to the right ventricle

Ewing's sarcoma is a round cell neoplasm derived from neural crest cells that is part of the primitive neuroectodermal tumor (PNET) family. It is a rare, aggressive malignancy that affects young people, most commonly in the second decade of life. The treatment of localized disease has improved greatly over the past four decades, but the prognosis for metastatic disease remains poor. Cardiac metastases of Ewing's sarcoma are exceedingly rare, with only a few reported cases. This article presents a case of a 22 year old man with a history of Ewing's sarcoma of the bone involving the right kneepeer-reviewe
