杨景涵:新盈利模式建立需要时间

截至5月9日,沪深300指数市盈率仅为11.06倍,低于全市场整体水平。A股的估值中枢明显下移,中国股市的市盈率正逐步向成熟市场的低市盈率水平靠拢。在300指数现今的估值水平下,如何来判断它的投资价值?为此记者采访了华泰柏瑞基金专户投资经理杨景涵。     

市盈率与上证指数非相关性实证研究

市盈率作为衡量股票内在价值的一个重要指标,在A股市场应用过程中,尤其是在衡量指数方面,遭遇了诸多模菱两可的困局,这给投资者和分析人士提出了严峻的挑战。尽管如此,市场在衡量指数投资价值或风险之时仍然对市盈率法乐此不疲。本文用金融计量相关方法对市盈率衡量指数是否合适进行实证研究,结果显示:市盈率与指数之间相关关系不成立;市盈率的变动对指数变动的解释程度很低,脉冲响应在相当长滞后期内不收敛,影响不确定;市盈率的变动(一阶差分)在很大程度上不是指数变动(一阶差分)的原因,而只是结果。因此,用市盈率来判断指数所处阶段的投资价值或风险并不科学。

证券市场市盈率的问题、修正与超越

市盈率是衡量股票投资价值和管理层据以调控的重要参考指标。投资者根据整体市场的市盈率的分析可以辨明市场风险，把握住投资较大板块和股票，获取较高的投资收益。管理层通过对市盈率水平的分析，可以准确把握股市的强弱，从而提出合理的调控措施，保证股市健康运行。然而，市盈率在会计核算以及在具体运用中，仍存在不少问题。一、市盈率的缺陷市盈率是股票的市场价格与每股税后利润(亦称每股收益)之比率，用倍数表示。它包括个股市盈率和平均市盈率两种核算口径。前者用以衡量某股票投资价值大小，后者则用以考察股市整体市场风险的高低…     

市盈率：历史演变轨迹及投资意义

市盈率作为简洁的估值指标,历来受到投资者的高度重视。本文首先梳理了前人对于市盈率指标的研究成果然后从行业市盈率的角度对中关两国的市盈率进行了对比研究。研究显示,市盈率对于不同行业投资的指导意义不同,而且市盈率是对看得见的未来的估价,资本市场越成熟,市盈率对于价值投资的指导意义就越强。     

小议企业价值评估中的持续经营假设

在企业价值评估中,主要的评估方法有收益法、加和法和市盈率倍数法,而其中收益法、市盈率倍数法都建立在企业持续经营假设基础上。持续经营假设即指在企业价值评估时,假定企业将按照原来的经营目的、经营方式持续地经营下去,它的运用是建立在对企业能够持续经营的专业判断上。笔者认为,可以从以下几个方面判断是否能够在企业价值评估中运用持续经营假设。     

当下好公司的估值到底高不高?

近期,市场还处于调整之中.现在很多人对于公司估值,又产生了分歧. 对于企业内在价值的评估,不同的人会有不同的看法.很多人习惯用市盈率来判断一个公司是不是高估,但是这种判断方法对于有些公司来说并不是适用.最明显的就是品牌消费品和新兴成长股等类别的公司. 首先,对于品牌消费品来说,如果只看市盈率相当于只考察公司的财务回报,...     

黄金有价玉无价——中国股市的估值风波

价值在于业绩,在于市场,某种意义上也就在于“自我”对它的认识。在市场人的眼里,动态市盈率远比静态市盈率更有实际意义。     

股票估值方法的中国证券市场适应性

股票投资估值方法 （一）相对价值法 1．市盈率法（P／E）市盈率法是最常用的价值评估法。市盈率又称价格收益比,是每股价格与每股收益之间的比率。决定公司股票价值的两个因素就是每股收益与市盈率。一方面,每股收益可以根据公司的经营状况、财务状况、税收状况等等,通过财务预算估算出来,一般要求算出未来2—3年的每股收益,而不仅仅是去年的或以前已经公告出来的每股收益。     

It Is Effective Measure to Set A Range for Reducing the Volatility of New Stocks

新股暴涨暴跌,其表现是在新股上市日遭爆炒和在新股发行之前就遭爆炒,高市盈率发行,其根本原因是一级市场与二级市场脱节,为此,新股上市日应设置涨跌幅,将两个市场联系起来,可抑制新股暴涨暴跌,有效抑制新股高市盈率发行,稳定股市。     

Debt and Taxes and Uncertainty

With a graduated personal tax schedule, Miller showed that there could be an equilibrium debt supply for the corporate sector as a whole. In the presence of uncertainty there is also a unique debt/equity ratio for each individual firm, and this ratio is related to the firm's operational risk characteristics. However, if firms merge and spin off in response to tax incentives, the identity of firms is ambiguous and only the corporate sector is a meaningful construct. These arguments are developed in both discrete and continuous models that employ extensions of the arbitrage-free pricing theory.     

教育与资本怎样的前景怎样的现实

来自政府的声音: "动员各种社会资源,发展教育" 此次论坛上财政部长助理张少春的发言是最受关注的发言之一.他的演讲传达出的信息有这样几方面:第一,谈到现实,他认为全社会对教育的巨大需求与我国公共投入不足已成为我国教育事业发展的突出矛盾.近年来,以公共部门投入为主,多渠道筹措教育经费的教育投入机制成为解决这一问题的重要途径,也使得公共部门与私营部门在教育领域的合作日益密切.第二,谈到前景,他认为,1.中国经济持续、快速的增长对高技能人才产生巨大的需求,这为私营部门的参与提供了广阔空间.2.随着公共财政职能的不断完善,财政资金将在各项教育事业中重新进行分配,进一步优化财政支出结构,提高资金的使用效率.在"十一五"期间,我国将把公共支出的重点转移到农村.我们将逐步把全体农村适龄儿童的义务教育全部纳入公共财政体制.     

Director gender and mergers and acquisitions

Does director gender influence CEO empire building? Does it affect the bid premium paid for target firms? Less overconfident female directors less overestimate merger gains. As a result, firms with female directors are less likely to make acquisitions and if they do, pay lower bid premia. Using acquisition bids by S&P 1500 companies during 1997–2009 we find that each additional female director is associated with 7.6% fewer bids, and each additional female director on a bidder board reduces the bid premium paid by 15.4%. Our findings support the notion that female directors help create shareholder value through their influence on acquisition decisions. We also discuss other possible interpretations of our findings.     

Political corruption and mergers and acquisitions

This research examines the relation between political corruption and mergers and acquisitions (M&As). We find that local corruption increases firm acquisitiveness but decreases firm targetiveness. The levels of corruption in acquirer areas relate positively to the bid premiums and negatively to the likelihood of deal completion. Corruption motivates acquiring firms to use excess cash for payment, which mitigates the negative effect of corruption on acquirer shareholder value. The evidence indicates that acquisitions help acquiring firms convert cash into hard-to-extract assets and relocate assets from the high to low corruption areas, thereby shielding their liquid assets from expropriation by local officials.     

Trust and cross-border mergers and acquisitions

A number of studies suggest that social trust matters for investment. Using different measures of trust from World Values Survey, we show that countries where people display higher levels of trust engage in more cross-border M&A activities. When they do, these acquirers pay lower premiums. To the extent that these acquirers also tend to engage in larger acquisitions as well, our findings suggest that a larger selection pool of potential targets and higher value targets enable these acquirers to negotiate for lower premiums. We do not find evidence of the significant effect for target country trust levels. Hence, trust may benefit those acquiring firms in cross-border transactions.     

Tournament-based incentives and mergers and acquisitions

This research examines the relation between tournament-based incentives, which are proxied by the difference between a firm's CEO pay and the median pay of the senior managers, and mergers and acquisitions (M&As). We find that tournament-based incentives are positively related to firm acquisitiveness and acquiring firms' stock and operating performance. Further analysis indicates that positive acquisition performance increases the likelihood of the CEO being promoted from inside the acquiring firm. Our evidence is consistent with the view that tournament-based incentives motivate acquiring firms' managers to make greater efforts and take more risk that result in superior acquisition performance.     

Corporate Innovations and Mergers and Acquisitions

Using a large and unique patent‐merger data set over the period 1984 to 2006, we show that companies with large patent portfolios and low R&D expenses are acquirers, while companies with high R&D expenses and slow growth in patent output are targets. Further, technological overlap between firm pairs has a positive effect on transaction incidence, and this effect is reduced for firm pairs that overlap in product markets. We also show that acquirers with prior technological linkage to their target firms produce more patents afterwards. We conclude that synergies obtained from combining innovation capabilities are important drivers of acquisitions.     

East and west and north and south : A preliminary model

The Brandt report and other proposals for a new North-South world order continue to be the focus of lively debate, yet it is often argued that little concrete has emerged from their recommendations. A major reason for this, the author argues, is that the East-West conflict component is not sufficiently taken into consideration-East-West tensions are a severe constraint on and a determining factor of North-South relations. Using influence diagrams, the author develops a flexible framework for discussion and assessment of N/S-E/W relations.
