对我国股市市盈率与非流通股问题的思考

我国股票市场的市盈率由于上市公司股权的分割而高企,而高企的市盈率会对今后股票市场及经济的稳定发展产生消极的影响。非流通股在二级市场的流通可以降低股市的市盈率并且改善上市公司的股权结构,在解决非流通股流通时要兼顾各方的利益。     

从瑞幸事件看新证券法下强化财务造假监管

证券法此次修订大幅提高了对财务造假行为的惩戒力度,并新增域外效力条款,将证券法管辖范围延伸至境外发行和交易活动。对于中概股财务造假,管辖权的主张应在遵守国际礼让原则的前提下,结合境内市场和投资者利益受影响程度审慎为之。在发行注册制改革的背景下,提高发行上市企业质量的关键还是在于强化事中事后监管,特别是要提高民事和刑事追责力度,积极推进退市市场化、常态化。     

证券监管自由裁量权及其制约机制研究

缘于证券法律的不完备以及证券监管技术性和效率性的要求,证券监管及其自由裁量权的存在有其必然性。由于行使过程中有一定的自由裁量空间和个人判断,证券监管自由裁量权可能会被滥用,表现为证券监管机构拖延甚至不履行职责、在具体证券监管行为中监管措施前后不一、滋生权力寻租等。为维护社会秩序的公正与公平,将证券监管自由裁量权被滥用的可能性降到最低,需要完善实体法和程序法来限制证券监管自由裁量权的范围与幅度,强化行政和司法监督机制对证券监管自由裁量权的制约。     

开放格局下证券公司价值增值研究

续中国签署WTO协议后,第二轮中美战略与经济对话将促进中国证券业市场进一步开放,高盛在中国的发展反映了中国证券市场的开放历程。通过考察开放格局下中国证券公司和美国证券公司的差距,以及不同规模的中国证券公司之间收入结构异同,认为在目前中国证券公司不具有竞争优势的情况下,中国应学习日本、韩国和台湾地区的谨慎开放政策和与经济实力相辅原则,控制开放速度及培育有利于中国证券业可持续发展的竞争格局。不同规模的中国证券公司必须通过对外部环境和自身优劣势科学分析,找出促进自身价值增值的战略和途径,培育各具特色的核心竞争力。     

论我国证券交易基础账户的法律体系与担保

证券账户体系是维护证券结算顺利实现的基石,其法律性质表现为以账户为客体、以账户主体为核心、以账户功能为内容、以明确账户财产归属为目标的权利义务关系群。按照证券交易的逻辑顺序展开实证分析,阐论了"虚"实"证券基础账户的法律体系和内在关联,确立了投资者资金账户的财产权法律保护机制,可从交易规范上明确投资者、证券公司和证券登记结算机构间的资产流转法律关系。     

Distribution of occupation times for constant elasticity of variance diffusion and the pricing of α-quantile options

The main results of this paper are the derivation of the distribution functions of occupation times under the constant elasticity of variance process. The distribution functions can then be used to price α-quantile options. We also derive the fixed-floating symmetry relation for α-quantile options when the underlying asset price process follows a geometric Brownian motion.     

Inflation Expectations and Risk Premiums in an Arbitrage‐Free Model of Nominal and Real Bond Yields

Differences between yields on comparable‐maturity U.S. Treasury nominal and real debt, the so‐called breakeven inflation (BEI) rates, are widely used indicators of inflation expectations. However, better measures of inflation expectations could be obtained by subtracting inflation risk premiums (IRP) from the BEI rates. We provide such decompositions using an affine arbitrage‐free model of the term structure that captures the pricing of both nominal and real Treasury securities. Our empirical results suggest that long‐term inflation expectations have been well anchored over the past few years, and IRP, although volatile, have been close to zero on average.

Investor Relations （IR） in Business Communication on the Example of Poland

This paper focuses on investor relations （IR） as an element of companies＇ communication with the external environment. It shows the place and role of IR in communication with the general market, and the stock exchange market in particular. The study is illustrated with an example of IR in Poland, a relatively new European Union （EU） member state and an emerging market. As can be seen, IR goes beyond the traditionally understood maintenance of communication with the capital market. It is also shown that the main role of IR ought to be the reduction of investment risk and enhancement of the companies＇ value, which is of particular significance in light of the current globalization of capital markets. It has been found that Polish companies, especially those listed on the Warsaw Securities Exchange （WSE）, commonly rely on IR as a means of communication with the environment. And yet, as the results of the analysis show, the quality of that communication is still far from satisfactory, despite efforts undertaken by various external entities to encourage more focus on the development of IR, or understanding of the company＇s relevant staff of its important role.
