The total set of industries from Value Line is used to demonstrate that business risk and return are negatively correlated across companies within industries. Some empirical questions about industries themselves are also raised. The concepts of income smoothing and corporate strategy are utilized to explain this apparent paradox. Further work is both suggested and

This paper analyzes 4,750 mergers from 1963 to 1998 to characterize the risk and return in risk arbitrage. Results indicate that risk arbitrage returns are positively correlated with market returns in severely depreciating markets but uncorrelated with market returns in f lat and appreciating markets. This suggests that returns to risk arbitrage are similar to those obtained from selling uncove...

In this case study, an early-career clinician-investigator discusses impending and future career issues in an interview with an established translational scientist, who then shares ideas about pursuing clinically informed research questions.

SHARPE [12] AND LINTNER [7] have recently proposed models directed at the following questions: (a) What is the appropriate measure of the risk of a capital asset? (b) What is the equilibrium relationship between this measure of the asset's risk and its one-period expected return?^ Lintner contends that the measure of risk derived from his model is different and more general than that proposed b...

The variance risk premium, defined as the difference between the actual and riskneutral expectations of the forward aggregate market variation, helps predict future market returns. Relying on new essentially model-free estimation procedure, we show that much of this predictability may be attributed to time variation in the part of the variance risk premium associated with the special compensati...

Except for specialists, planetary seismology refers first to Earth seismology, and stimulates thoughts about earthquakes, tsunamis, and all such rare and brutal events that everyone knows by experience and/or fears. According to etymology, seismology shakes and shocks our bodies and our minds. According to semantics, all languages make the difference between “superficial” and “deep” things, so ...

This article proposes semiparametric least squares estimation of parametric risk-return relationships, i.e. parametric restrictions between the conditional mean and the conditional variance of excess returns given a set of unobservable parametric factors. A distinctive feature of our estimator is that it does not require a parametric model for the conditional mean and variance. We establish con...

Marketing managers can increase shareholder value by structuring a customer portfolio to reduce the vulnerability and volatility of cash flows. This article demonstrates how financial portfolio theory provides an organizing framework for (1) diagnosing the variability in a customer portfolio, (2) assessing the complementarity/similarity of market segments, (3) exploring market segment weights i...
