International Asset Pricing and Portfolio Diversification with Time‐Varying Risk
Published: 04/18/2012 | DOI: 10.1111/j.1540-6261.1997.tb02745.x
GIORGIO SANTIS, BRUNO GERARD
We test the conditional capital asset pricing model (CAPM) for the world's eight largest equity markets using a parsimonious generalized autoregressive conditional heteroskedasticity (GARCH) parameterization. Our methodology can be applied simultaneously to many assets and, at the same time, accommodate general dynamics of the conditional moments. The evidence supports most of the pricing restrictions of the model, but some of the variation in risk‐adjusted excess returns remains predictable during periods of high interest rates. Our estimates indicate that, although severe market declines are contagious, the expected gains from international diversification for a U.S. investor average 2.11 percent per year and have not significantly declined over the last two decades.
Trading and Manipulation Around Seasoned Equity Offerings
Published: 03/01/1993 | DOI: 10.1111/j.1540-6261.1993.tb04707.x
BRUNO GERARD, VIKRAM NANDA
We investigate the potential for manipulation due to the interaction between secondary market trading prior to a seasoned equity offering (SO) and the pricing of the offering. Informed traders acting strategically may attempt to manipulate offering prices by selling shares prior to the SO, and profit subsequently from lower prices in the offering. The model predicts increased selling prior to a SO, leading to increases in the market maker's inventory and temporary price decreases. Further, since manipulation conceals information, the ratio of temporary to permanent components of the price movements is predicted to increase.
