We comprehensively analyze the predictive power of several option-implied variables for monthly S&P 500 excess returns and realized variance. The correlation risk premium (CRP) and the variance risk premium (VRP) emerge as strong predictors of both excess returns and realized variance. This is true both in- and out-of-sample. Our results also reveal that statistical evidence of predictability does not necessarily lead to economic gains. However, a timing strategy based on the CRP leads to utility gains of more than 5.03% per annum. Forecast combinations provide stable forecasts for both excess returns and realized variance, and add economic value.  相似文献

Transition matrix techniques are used to relate the past and present performance of pension fund portfolios. In particular, funds are ranked to study the tendency of portfolios to remain in the same quartile of the ranking as they were in the previous period. For raw returns, funds in both of the top quartiles are found to be more likely to remain in the same quartile than would be expected by chance. This result can be taken as limited evidence for the consistency of performance. Similar systemic effects are observed on a risk-adjusted basis. There appears to be clear evidence that some fund managers can offer a degree of consistent good performance.  相似文献

This research responds to the attendant need for empirical evidence pertaining to how marketing affects firm performance. Using the Fama-French method, common in finance, and a leading marketplace measure of a brand’s financial equity value, the authors provide empirical evidence for the branding-shareholder value creation link. The results extend previous research by showing that strong brands not only deliver greater returns to stockholders than does a relevant benchmark but do so with less risk This finding holds even when market share and firm size are considered.

行为资产组合理论:理论基础、内容及对异象的解释   总被引:1,自引:0,他引:1  
行为金融理论于20世纪80年代兴起,它通过将行为因素引入决策过程从而对传统的金融理论做出补充。谢夫林(Shefrin)和斯特曼(Statman)在现代资产组合理论的基础上提出了行为资产组合理论,该理论是行为金融的理论基础之一。行为资产组合理论的基础包括安全第一组合理论和安全、潜力和期望理论。内容分为单一账户资产组合理论和多重账户资产组合理论。行为资产组合理论能够对市场中的一些异象做出合理的解释。  相似文献

Through Joint Implementationand the Clean Development Mechanism, reductionsof greenhouse gas emissions achieved abroad canbe credited to domestic firms. However, thetechnical, economic and political risksinvolved may prevent the private sector frominvesting in such projects. This paperdescribes three types of risks which emissionreduction projects are exposed to. Eleven pilotprojects carried out under the ActivitiesImplemented Jointly (AIJ) program and financedby Sweden are evaluated. Actual project costsare found to exceed projected costs in allcases. Annual emission reductions also deviatefrom their expected values and vary stronglyover time, supporting the hypothesis that suchprojects are risky business. The riskmanagement tool portfolio diversification isapplied to a sample of Swedish AIJ projects.The results indicate that diversification canreduce the risks of greenhouse gas mitigationprojects significantly. Thus, carbon funds area promising way of lowering the risks of theKyoto Mechanisms for private sector investors.  相似文献

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying.  相似文献

Using the Hamilton-Jacobi-Bellman equation, we derive both a Keynes-Ramsey rule and a closed form solution for an optimal consumption-investment problem with labor income. The utility function is unbounded and uncertainty stems from a Poisson process. Our results can be derived because of the proofs presented in the accompanying paper by Sennewald (2006). Additional examples are given which highlight the correct use of the Hamilton-Jacobi-Bellman equation and the change-of-variables formula (sometimes referred to as ``Itô's Lemma'') under Poisson uncertainty.  相似文献
