What percentage of their portfolio should investors allocate to alternative investment vehicles? The only available answers to the above question are set in a static meanvariance framework, with no explicit accounting for uncertainty on the active manager’s ability to generate abnormal return. In this paper we consider the problem of an investor who can choose between the riskfree security and ...

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...

Bali and Cakici (2006) find no relation between equally-weighted portfolio returns and idiosyncratic risk, whereas Ang et al. (2006a) report a negative relation between value-weighted portfolio returns and idiosyncratic risk. Our analyses demonstrate that both findings can be explained by short-term monthly return reversals. The abnormal positive returns from taking a long (short) position in t...

This paper provides new evidence about the link between firm level total factor productivity (TFP) and stock returns. We estimate firm level TFP and show that it is strongly related to several firm characteristics such as size, the book to market ratio, investment, and hiring rate. Low productivity firms earn a significant premium over high productivity firms in the following year, and this pre...

This paper measures the mean, standard deviation, alpha, and beta of venture capital investments, using a maximum likelihood estimate that corrects for selection bias. The biascorrected estimation neatly accounts for log returns. It reduces the estimate of the mean log return from 108% to 15%, and of the log market model intercept from 92% to 7%: The selection bias correction also dramatically ...

The basic components of the risk/return model applicable to insurance consist of underwriting return, investment return and leverage. A pricing approach is presented to deal with underwriting and investment risk, guided by basic risk/return principles, which addresses the policyholder and shareholder perspectives in a consistent manner. A methodology to determine leverage is also presented, but...

Given two virtually separate literatures on return predictability and the risk-return relation, this paper reconciles the two literatures by investigating the underlying mechanism of the return predictability literature through exploiting the risk-return relation. In developing an empirical model to examine the business cycles-risk-return relationship, we consider the fact that market volatilit...
