关于CAPM适应性的论述

资本资产定价模型(CAPM)是目前证券市场上应用最广泛的模型。但是同时,它也存在一定的局限性。首先,论述了资本资产定价模型的由来和应用范围;然后,从资本资产定价模型的假设和参数估计方面,提出了资本资产定价模型的局限性;并论述了该模型在我国证券市场的适应性。针对此模型的局限性,目前大量学者发展了CAPM,但是仍然没有一个模型能完全替代资本资产定价模型。

资本资产定价模型在证券投资中的应用

作为现代金融理论的三大基石之一,资本资产定价模型经常被西方发达国家的投资者用来解决金融投资决策中的一般性问题,在诸如资产定价、投资组合业绩的测定、资本预算、投资风险分析及事件研究分析等方面得到了广泛的应用。一、资本资产定价理论简介(一)理论渊源资本资产定价理论是在马克维茨投资组合理论和资本市场理论基础上形成发展起来的一种证券投资理论,主要研究证券市场中资产的预期报酬率与风险资产之间的关系,以     

CAPM模型在金融经济学中的应用

一、CAPM模型的简介 资本资产定价模型(CAPM)是通过寻求投资者为补偿某一给定风险水平的均衡收益率推导出来的.为了能够推导出只运用单一风险指数(被称为β)对必要收益定价的风险定价模型,资本资产定价模型的推导中做了一些严格的假设.CAPM模型包含三个组成部分:

主要介绍了单项本成本估算模型的产生、演变及其发展。     

行为资产定价模型的适用性研究

作为行为金融学主干的行为资产定价理论近些年来发展迅速。行为资产定价模型能否指导现实中的投资行为,取决于对行为资产定价模型的实证检验结果。本文利用我国证券市场数据对行为资产定价模型的适用性进行了检验,发现行为资产定价模型适用于股价上涨时期,而非股价下跌时期。     

电网建设项目融资租赁基准收益率的确定

在电网建设项目融资租赁中,出租人进行投资决策时首先面临的问题就是确定项目融资租赁的基准收益率。采用资本资产定价模型(CAPM)与加权平均资本成本法相结合的方法,计算出了电网建设项目融资租赁的基准收益率。该方法不但适用于电网建设项目融资租赁,同样适用于其他行业的融资租赁项目。     

A Reduced Rank Regression Approach to Tests of Asset Pricing

Both the Arbitrage Pricing Theory (APT) and the Capital Asset Pricing Model (CAPM) place restrictions of the cross-sectional variation of conditional expectations of asset returns and of macro indicators. We show that these restrictions imposed on the reference statistical models lead to special cases of the reduced rank regression model. The maximum likelihood problem is solved by canonical correlation analysis. Likelihood ratio tests about the number of factors underlying stock returns are straightforward to calculate, thus allowing discrimination between competing financial theories. Moreover LR tests on the relevance of each macroeconomic indicator within a chosen model can be implemented. Some of the tests are illustrated by an application to Italian stock market data.     

基于模糊收益率的CAPM实证检验

首先引入模糊收益率的概念,讨论了基于模糊线性回归模型的资本资产定价模型(CAPM)变化形式。作为应用,随机选取上海证券交易所的一支股票,安徽合力(600761),统计该股票在2009年1月1日至2010年12月31日的周收益率以及同期的市场周收益率,共102个数据。对所取得的数据进行模糊化和平移处理,求出其模糊回归方程。利用2011年的数据对回归方程进行检验,结果显示回归方程的拟合效果符合实际,CAPM在单支股票上是可行的,可用于指导实际的投资操作。     

欧洲股票市场的规模和动因:基于不同β系数的资本资产定价模型实证研究

我们选用在13个欧洲股市上市的证券,形成规模和动因组合。我们不仅发现规模溢价的证据,还发现8个样本市场存在重大动因收益率。这些收益率可能不构成异常现象,因为它们与不同β值的资本资产定价模型一致。我们还发现,系统风险与经济周期有关。此外,研究结果显示,虽然规模和动因收益率显著,但是难以在中、短期利用它们,因为在我们的样本中只有极少年份它们的数值为正且很大。     

Restricting capital outflow

According to the “Capital Asset Pricing Model”, an individual can increase his utility by diversifying his capital across countries. If that is the case, then why do governments impose restrictions on capital outflow? This paper argues that foreign owners of capital have less political power than domestic ones and therefore capital liberalization weakens the political power that protects capital, increases the taxation of capital and thus reduces total investment. Indeed, most of the empirical evidence suggests that capital liberalization is positively correlated with government expenditure, social security spending and corporate taxation.     

Agency costs and the discount rate for public sector enterprises

In this paper, we examine the implications of agency costs on the discount rate for public sector enterprises (PSEs); we do this in the framework of the Capital Asset Pricing Model. With the addition of agency costs, the discount rate for Public Sector Enterprises (PSEs) under uncertainty becomes the risk-adjusted discount rate plus a premium for agency costs; under certainty, the discount rate for PSEs is shown to be the risk-free rate plus a premium for agency costs. Use of a discount rate by PSEs without adjusting for agency costs both under certainty and uncertainty, will lead to sub-optimal capital investment decisions by PSEs.     

Portfolio selection in thinly traded environments—a case study

This paper proposes a flexible technique for selecting portfolios in an environment which includes thinly traded shares. The proposal uses the Capital Asset Pricing Model with a thinly traded beta estimator to generate the expected return input. This technique has the advantage of being applicable when the opportunity set includes well-traded securities, as the beta estimator converges to the ordinary least squares beta for well traded shares. In addition, it allows portfolio estimation to be carried out under a range of expected market performance scenarios. An empirical study on the Johannesburg Stock Exchange over the period 1974–85 indicates that the proposed method is superior to traditional techniques.     

Risk and return in the Tehran stock exchange

This paper analyzes market index returns in the Tehran stock exchange (TSE) within the context of three variants of the Capital Asset Pricing Model: the static international; the constant-parameter intertemporal; and a Markov-switching intertemporal CAPM, which allows for time-varying degree of integration with regional and international equity markets. We find that TSE returns are CAPM-efficient at monthly frequency with respect to several international market indices. Moreover, we find evidence in support of international integration of the TSE with respect to international markets. In addition, we conduct an extensive investigation for the direction of causality between TSE returns, international market index returns, and those in neighboring countries.
