评价上市公司基本获利能力的投资资本报酬率指标   总被引:2,自引:0,他引:2  
净资产收益率是上市公司披露的重要财务指标之一,但它用来衡量公司的经营业绩时仍有许多缺陷,因受多种因素影响,单纯用它评价公司业绩是不确切的。投资资本报酬率作为衡量上市公司基本获利能力的指标之一,可以克服净资产收益率的不足。  相似文献

<正>一、资本资产定价模型的理论探讨(一)资本资产定价模型的基本概念资本资产定价模型(简称CAPM)是继哈里·马科维茨于1952年建立现代资产组合理论后,由威廉·夏普和约翰·林特、简·莫森等人创立的。该模型主要研究证券市场中均衡价格是怎样形成的,以此来寻找证券市场中被错误定价的证券。它在现实市场中得到广泛的应用,成为普通投资者、基金管理者和投资银行进行证券投资的重要工具之一。但是,CAPM模型是在一系列假定条件下成立的,而其中“的证券市场是有效的”假设,在现实的证券市场中实际上是很难达到的。因此人们对CAPM的适用性提出了质疑。本文试图针对我国证券市场的实际情况,找出影响证券市场效率的原因,提出解决问题的方法,以提高CAPM模型在我国  相似文献

本文以1999年3月到2011年3月的沪深主板上市公司月收益率为样本,通过定义机构投资者的投资策略,对加入机构投资者影响后的CAPM扩展模型进行实证研究,发现扩展模型消除了经典CAPM中存在的异方差性,且不存在一阶自相关性;资产组合的收益率同市场组合收益率呈反比关系,与基准投资组合收益率呈正比关系;模型拟合度有了很大的改善。机构投资对我国资本市场资产价格产生了积极的影响。因此,我国资本市场应该大力发展机构投资者,机构投资者本身也应该朝着健康的方向发展。  相似文献

大宗商品期货市场是我国资本市场的重要组成部分,其定价有效性关系到投资者套期保值和价格发现等功能的实现。本文对国际前沿研究中常用的定价因子进行全面系统梳理,并对这些因子对我国商品期货合约收益率的解释和预测能力进行检验。在此基础上,本文构建了适用于我国大宗商品期货市场的包含市场、基差以及基差动量的三因子定价模型。进一步研究表明,基于大宗商品存储理论和现货存货数据构建的投资组合收益率可以被本文三因子模型有效解释,验证了经典的存储理论在我国的适用性。此外,本文对基差与基差动量两个重要因子的经济学意义进行了阐释。本文研究为进一步厘清大宗商品期货市场定价机制提供了一定参考。  相似文献

一、债券投资收益 债券投资收益主要来源于三个方面,即利息收入、偿还盈亏(资本利得)和利息再投资所得的收益.度量收益常用的指标是收益率.债券的收益率是指债券投资每年所获得的收益占投资总额的比率.债券的收益率有多种多样,从发行时购买一直持有到偿还日的收益率叫认购者收益率;在发行时买入,中途卖出的收益率叫持有期间收益率;在二级市场上买入,持有一段时间又卖出的收益率叫买卖收益率.我们通常所说的收益率是指在债券上市后中途买入并一直持有到期的收益率,即到期(最终)收益率(Yield to Maturity).决定债券收益率的主要因素有:票面利率、购买价格、剩余年限、附息债券利息再投资收益率.这些因素相互变化,收益率也随之变化.要进行债券投资,就必须熟悉各类债券收益率的计算.  相似文献

The effect of barriers to international investment (in the form of differential taxation) upon a firm's investment and financing decision is analyzed through a newly derived international capital asset pricing model. A firm using an improper project selection criterion which fails to account for the effect of barriers to international investment may reject a desirable project with high systematic risk, whereas it may incorrectly accept an undesirable project with low systematic risk. The financial risk premium under barriers is greater than that in the absence of barriers to international investment. In addition, the lower is the degree of barriers to international investment, the more domestic securities will gain, even when both countries impose a tax on investors of different nationality.  相似文献

Controlling Investment Decisions: Depreciation- and Capital Charges   总被引:9,自引:5,他引:4  
This paper examines a multiperiod principal-agent model in which a divisional manager has superior information regarding the profitability of an investment project available to his division. The manager also contributes to the periodic operating cash flows of his division through personally costly effort. We demonstrate that it is optimal for the principal to delegate the investment decision and to base the manager's compensation on the residual income performance measure. Our analysis points to a class of depreciation rules and to a particular capital charge rate which together ensure that a profitable (unprofitable) project makes a positive (negative) contribution to residual income in every period. As a consequence, the compensation parameters for each period can be chosen freely so as to address the moral hazard problems without impacting the manager's investment incentives.  相似文献

This paper shows that it is not always correct to make an upward adjustment to the stock beta in calculating the hurdle rate for capital budgeting even when the project under consideration is riskier than existing assets. The paper also shows that the correct hurdle rate is smaller than the market capitalization rate calculated from the firm's stock beta when the project under consideration has the same risk as existing assets. In addition, it is shown that the market capitalization rate will be an underestimate (overestimate) of the correct hurdle rate when the risk of future assets is greater (smaller) than both the risk of assets in place and that of future capital expenditures. These new results are direct consequences of the insight that the firm's investment opportunities are in fact real call options written on underlying assets.  相似文献

This paper attempts to present an integrated valuation analysis of investment options involving margin trading. The analysis is based on valuation theories such as Modigliani and Miller's capital structure model, the capital asset pricing model and the option pricing model. It is shown (i) that in margin trading, the return on equity is given by the return on investment plus a risk premium which increases proportionally with the margin-trading rate; (ii) that both the total risk (variance) and systematic risk (beta) of the return on equity increases proportionally with those associated with the return on investment; and (iii) that, when the option pricing model is applied to the case of margin trading, a more precise valuation formula can be employed.  相似文献

This article calls attention to a difficulty with insurers' investment policies that seems to have been overlooked so far. There is the distinct possibility that insurers cannot satisfy the demands of different stakeholders in terms of expected returns and volatility. While using the capital asset pricing model as the benchmark, this article distinguishes two groups of stakeholders that impose additional constraints. One is “income security” in the interest of current beneficiaries and older workers; the other is “predictability of contributions” in the interest of contributing younger workers and sponsoring employers. It defines the conditions for which the combination of these constraints results in a lack of feasibility of investment policy. Minimum deviation from the capital market line is proposed as the performance benchmark in these situations.  相似文献

We compare stock performance based on utility indifference pricing and the Sharpe ratio assuming that stock returns follow the class of discrete normal mixture distributions. The utility indifference price with an exponential utility function satisfies several desirable properties that a suitable value measure should satisfy. For utility indifference pricing, we employ the inner rate of risk aversion proposed by Miyahara [Evaluation of the scale risk. RIMS Kokyuroku, No. 1886, Financial Modeling and Analysis (2013/11/20-2013/11/22), 181–188, 2014], which is the degree of risk aversion that makes the utility indifference price with the exponential utility function zero in order to evaluate stock performance. Using a selection of U.S. stocks, the results show that the evaluation of stock performance based on the inner rate of risk aversion is more relevant for risk-averse investors than that based on the Sharpe ratio, which represents performance by the first two moments.  相似文献

The paper proposes an intertemporal equilibrium model that highlights the interdependence between aggregate investment and the degree of product differentiation with free entry of monopolistic producers. An investment externality is identified that results in underaccumulation of capital in the decentralized market equilibrium. Some form of investment promotion is called for. The paper compares the effectiveness of a general investment tax credit and an ad valorem output subsidy with policies that favor smaller business size. It is also shown that the complementarity among individual investments creates a potentially powerful investment multiplier.  相似文献

It is now widely accepted that contrarian, or value investment strategies deliver superior returns. Gregory, Harris and Michou (2001) examine the performance of contrarian investment strategies in the UK and find that value strategies formed on the basis of a wide range of measures of value have delivered excess returns that are both statistically and economically significant. However, while value strategies appear to be profitable, the reason for their superior perform‐ ance is far from clear. Under the contrarian model, value strategies are profitable because they are contrarian to naïve strategies such as those that erroneously extrapolate past performance, while under the rational pricing model, value strategies are profitable because they are fundamentally riskier in some sense. In this paper, we discriminate between these two possibilities by undertaking a comprehensive investigation of the relationship between the returns to value investment strategies and various macroeconomic state variables that in a multi‐factor asset pricing model could reasonably be taken as proxies for risk. Moreover, we examine whether the returns to value strategies predict future GDP, consumption and investment growth over and above the contribution of the Fama and French (1993 and 1996) SMB, HML and market factors. While the SMB and HML factors behave in a manner consistent with the rational pricing model, we show that some value strategies in the UK are able to generate excess returns that do not seem to be related to known risk factors.  相似文献

本文以2007-2016年的A股上市公司为样本,实证检验中国再融资监管制度是否促进了企业的理性投资行为。研究发现:上市企业投资决策符合资本成本约束的理性准则,表明中国权益市场中存在普遍的市场约束力量;但企业再融资后投资理性程度明显降低;对监管失效的原因分析表明,企业投资理性程度下降受到事前融资动机和事后募资投向变更的影响:监管规则对事前再融资动机缺乏有效把控,导致再融资资格出现错配;而对事后募资用途的监管不严,则导致部分企业对募集资金的用途进行随意变更,使得企业投资理性程度降低。研究结论为完善企业投资决策自治机制、优化权益再融资监管、促进资本市场改革提供了实证依据和一定的现实启示。  相似文献
