刍议国有股减持

国有股减持是必要的，也是必须的，但由于国有股减持中减持价格不合理，减持主体不规范及相关各方地位不平等问题的存在，使国有股减持引起市场的动荡。因此，国有股减持必须精心设计，合理确定减持价格，采用多种减持方式，合理确定减持节奏，在一个统一的市场规则下公平、有序、透明地进行。     

利用指数基金来减持国有股

国有股减持问题成为证券市场最受关注的话题之一.2001年6月12日出台了《减持国有股筹集社会保障资金管理暂行办法》,对国有股减持作出了"原则上采取市场定价方式"的规定,在二级市场中增发新股的同时,对国有股进行存量减持,即按同样的价格、10%的比例减持,过高的定价使市场信心受挫,沪深出现大跌.     

国有股内在价值的计量标准与实证研究

正确计量国有股的内在价值，确定公平、合理的市场价格，对于顺利减持国有股具有重要的现实意义；而由折现现金流模型确定的国有股内在价值，充分体现了国有股作为金融资产的特性，是比较理想的国有股定价参考依据。     

国有股减持的十二种主要方案

为 了解决股权分裂问题 ,我国许多专家对国有股减持的问题进行了探讨 ,提出了大约 40 0 0多个减持方案。中国财经大学教授贺强认为 ,有价值的方案主要有 12种。向A股市场配售方式　在A股市场 ,将国有股向新老股东进行配售 ,在确定配售价格时 ,首先确定一个下限基准价 ,该价格以     

国有股减持与资本市场的均衡发展

均衡发展是资本市场运行的最佳状态，然而我国上市公司的国有股份比重过大且不能流通却严重影响了资本市场的均衡发展。国有股减持是一个复杂的系统工程，关系到国家、公司和投资者的利益，影响到资本市场资金、股票的供求平衡，影响到股价的波动，最张影响到资本市场的均衡发展。国外在国有股减持过程中，很重视资本市场上各市场关系的均衡。我们有必要在国有股减持的程序高度、减持步骤及价格的确定等方面体现市场均衡的精神。     

认股权证与国有股减持定价

国有股减持是一项复杂的系统工程 ,不仅关系到国有经济战略布局的调整、国企改革的成败 ,而且还关乎中国证券市场的可持续发展。其中 ,如何合理地确定国有股的减持价格 ,从而平衡市场各方的经济和利益关系 ,更是社会各界广泛关注的焦点。本文在提出了一种“新股新办法 ,老股老办法”的方案后 ,着重论述了发行认股权证在“老国有股”减持定价中的运用 ,以期发现一种解决问题的方法。     

关于停止国有股减持的再思考

本文认为 ,停止国有股减持只是说明在国有股减持的方法、步骤、时机以及价格等方面存在着不合时宜的地方 ,而决不意味着放弃解决国有股流通、国有股“一股独大”的问题。从改革和发展的角度来看 ,国有股减持是经济体制改革、资本市场发展必过的大关 ,是一种必然的趋势。当然 ,减持国有股必须注意处理好多方面的关系 ,包括国有股减持与证券市场发展、社保体系完善、股权全流通的关系 ,稳定与发展的关系 ,政府各部门之间的关系等 ;同时 ,还要坚持公平、多样化、稳步推进的原则 ,积极妥善地解决国有股减持问题。     

国有股减持方案分析及其政策建议

《减持国有股筹集社会保障资金管理暂行办法》的出台，标志着国有股减持工作正式拉开了序幕。本文从我国证券市场国有股现状入手，结合国外国有股减持的目标，阐述了我国国有股减持的意义所在，从市场承受能力、国有股产权所有问题、持股成本、股权结构调整等方面分析了国有股减持面临的主要问题，并对《管理办法》中的三种减持方式进行了分析，最后以国有股减持应有改善上市公司治理结构、保护各方参与者利益，实现减持所获资金的有效利用为原则，提出了完善相关法律法规、改革新股发行制度、明确国有股减持的领域、步骤及定价，综合平衡各方利益等政策建议。     

国有股减持与流通的目标和对策研究

目前我国上市公司由于国有股绝对控股且不能流通,使得证券市场缺乏有效的产权制度基础,难以形成有效的公司治理结构,企业经营机制得不到转变,国有股减持与流通成为长期困扰股市的一大难题,国有股减持的主要难点是同股不同价,必须将国有股的成本价与二级市场股价的关系理顺,并处理好国家、上市公司和股民的利益关系,国有股减持与上市才不会引起股市的动荡。     

国有股减持存在的问题及建议

2001年6月，国务院发布了《减持国有股筹集社会保障基金暂行办法》（以下简称《办法》）。《办法》的出台，引起了市场的极大关注。国有股减持，对筹集社保基金、改善企业法人治理结构、加快建立现代企业制度和证券市场健康发展都有重大意义。本文拟就国有股减持中的若干问题提出一些思考和建议。一、国有股减持存在的问题1. 国有股减持的目的值得商榷。国有股减持最主要的是解决上市公司股本结构不合理、国有股“一股独大”的问题，其目的应该是完善资本市场，而此次减持却是为了填补社保基金缺口，补充一部分社保基金，这只是减持以后资金…     

The Effectiveness of Price Limits and Stock Characteristics: Evidence from the Shanghai and Shenzhen Stock Exchanges

We examine the effectiveness of price limits on Chinese A shares and investigate the characteristics of those stocks that hit their price limits more frequently. We find that the effect of price limits is asymmetric for the A shares in upward and downward price movements and different for bullish and bearish sample periods. During a bullish period price limits effectively reduce stock volatility for downward price movements, but not for upward price movements; while during a bearish period price limits effectively reduce stock volatility for upward price movements, but not for downward price movements. Second, price limits delay efficient price discovery for upward price movements, but not for downward price movements. However, we do not find evidence to suggest that price limits harmfully interfere with the stock trading processes in the Chinese A share markets. Finally, we find that actively traded stocks hit their price limits more often and tend to hit the lower limit more frequently when overall market conditions are bearish. Stocks with high book-to-market values of equity hit their upper price limits more frequently, while stocks with a high ratio of tradable shares tend to hit their price limits less frequently.JEL Classification: G10, G14, G15     

Stock Returns and Volatility under Market Segmentation: The Case of Chinese A and B Shares

In most countries where firms list separate shares for trading by foreign and domestic investors, the prices of the foreign shares tend to be higher. In China, the reverse tends to be true. In this paper, we would like to focus on the information content in lagged premiums of Chinese A over B traded shares. The lagged premiums are found to have certain predictive power over the future returns and volatility of both A and B shares, with some interesting patterns. Specifically, an increase in the premium ratio of A shares will be followed by a rise in the return of A shares and a fall in the return of B shares. It is found that both of the investors in Chinese A- and B-share markets reveal positive feedback trading behavior. Moreover, the liquidity and information availability will affect the magnitude of such behavior especially in B-share markets. By using multivariate GARCH model, it is also demonstrated that the unexpected changes in the premium ratio of A-share price over B-share price contribute to the return volatility of both A shares and B shares. These patterns may provide foundations for the development of pricing models for equity shares under market segmentation.

Price Differentials between Dual‐class Stocks: Voting Premium or Liquidity Discount?

A series of papers suggest that private benefits can explain the price differentials between stock classes carrying different voting rights. However, in Denmark the premium is negative for several firms over long periods. This indicates that in the absence of takeover contests, where the voting right becomes crucial in a transfer of corporate control, the price differential in stock classes with identical dividend rights is more likely to reflect investors’ liquidity risks. Whereas the existing literature tends to focus primarily on corporate control‐related explanations, this paper documents the impact of liquidity on price spreads between dual‐class shares.     

Dual Class Stock in Russia: Explaining a Pricing Anomaly

This paper studies the determinants of the unusually high and volatile price differential between common (voting) shares and preferred (nonvoting) shares in Russia's emerging stock market. It focuses on three potential explanations for the price spread between these two classes of stock: the control contest model of the voting premium, the inferior liquidity of preferred shares, and the risk of expropriation of preferred shareholders as a class. The regression analysis, based on data from 1997 to 2005, supports the control contest explanation and the liquidity argument. The hypothesis of expropriation of preferred shareholders as a class receives limited support, and only in the early period of the Russian stock market's development. The paper addresses the issue of structural breaks in the evolution of the price differential, related to the 1998 financial crisis and to improvements in investor protection in Russia in the early 2000s. It also provides new estimates of the magnitude of the private benefits of control in Russian companies.     

The appraisal of ordinary shares by Saudi investors

This paper reports on a questionnaire survey about share valuation practices among investors and their intermediaries in Saudi Arabia. The findings suggest that fundamental analysis is used most by investor respondents where a P/E multiple is applied to an earnings forecast to generate a prediction of future price. However, technical analysis is also used to a much greater extent than in developed markets. Finally, the results indicate that quarterly and annual reports as well as newspapers are widely consulted by investors when forming their expectations about share valuations.     

关于完善重大资产重组股份发行定价机制的思考

根据现行规定,重大资产重组交易中发行股份价格不能低于上市公司董事会决议公告日前20个交易日股票交易均价。但从目前实践看,该机制已不能很好地适应市场发展的需要。为此,本文从现行定价机制在实践操作中存在的问题入手,重点就现行定价机制无法较好反映非流动性折扣和控制权溢价等因素的实际情况进行研究,并通过分析借壳上市、整体上市和向第三方发行股份购买资产三种交易类型在现行定价机制下的利益平衡机制及其存在的问题,对下一步定价机制的改革有针对性地提出了相关政策建议,以期增加定价机制的合理性和灵活性,更好地适应和促进资本市场并购重组业务的发展。     

西方IPO抑价理论及对中国IPO研究的启示

西方IPO抑价理论大多在信息不对称、委托代理、信号显示等信息经济学框架下,基于资本市场的有效性假设而提出的,即假定二级市场对股票的定价是合理的,IPO抑价是源于发行定价偏低.中国A股市场IPO抑价率长期高企但逐年下降,对该问题的研究,不能简单套用西方理论,而必须结合我国证券市场环境及IPO发行审核制度,将制度因素作为内生变量来考察.
