A new perspective on performance persistence: evidence using portfolio holdings

We investigate the existence and sources of performance persistence for Australian equity funds, using monthly portfolio holdings data. We find significant persistence among outperforming rather than underperforming funds, which is primarily related to security selection skill, and is associated with growth‐orientated funds. Meanwhile, the relation between persistence and momentum is secondary and nuanced. Further, persistence largely derives from existing holdings, while subsequent active trading contributes only moderately positive returns for both outperforming and underperforming funds. We also find that persistence fades beyond 6 months and vanishes after 24 months. Our findings differ from those for U.S. equity funds and previous Australian studies, implying that persistence may vary with market context and its identification may depend on data availability.

我国证券市场信息不对称的模式分析

证券市场的信息不对称是市场主体之间的不对称,但是目前对于证券市场信息不对称的研究中,并未关注各类证券市场主体在信息不对称中的关系,本文中作者根据证券市场的主体分类,总结出我国证券市场信息不对称的10种模式,对各种模式进行了初步分析.     

我国证券市场税制改革研究

我国证券市场目前存在流转税过重、所得税混乱、财产税缺失、行为税错位等问题.证券税制应在遵循前瞻性与阶段性相统一、独立性与复合性相兼备、刚性与弹性相结合三大原则的基础上有针对性地进行改革,以达到促进证券市场稳定健康发展、减轻税负和规范税制以及与国际接轨的目标.从长期来看,对证券行业征收增值税甚至免税可能是最优选择.但对证券税制进行根本改革的大环境尚不成熟,我国金融和税制的完善还需要一段时间,因此,现阶段最切实可行的方案是对证券行业继续征收营业税,同时进行相关调整.     

证券公司治理结构:独立董事角度的分析

独立董事制度作为一种强化公司监督和制衡机制的制度，有利于解决我国证券公司长期以来国有股权虚置、“内部人控制”现象严重、公司内部信息和决策过程缺乏透明公开机制以及监事会形同虚设等问题。但是在具体引进过程中，还存在着一些制约因素，如独立董事的“独立性”问题、激励问题、权力和责任问题、独立董事的人数及其人员构成等。因此，我们要借鉴国外经验，结合我国实际情况，增强我国证券公司独立董事制度的有效性。     

完善我国证券流转税的若干思考

加入WTO后,我国现行的以证券交易印花税为主体的证券市场税制以及高昂的证券市场交易成本难以适应市场开放和与国际接轨的需要。随着我国证券市场的日益发展以及考虑到和国际证券市场接轨的需要,应尽快开征证券交易税代替现行的证券交易印花税;将印花税替换为证券交易税时应进一步降低税率;开征证券交易税时应考虑不同投资主体、不同证券品种和不同持有期限,实行不同的比例税率以抑制市场投机和平衡市场发展;在证券交易税设计时可以考虑仅对卖方征收;在“低税率”的同时实现“宽税基”。     

Economic policy uncertainty,institutional environments,and corporate cash holdings

We investigate the effect of economic policy uncertainty (EPU) on corporate cash holdings using a large sample of international firms. EPU intensifies concerns of investors on managerial self-dealing and political extraction. Consequently, the potential cost of cash holdings (i.e., expropriation) outweighs its benefit (i.e., precautionary motives), and the optimal amount of cash holdings decreases. We find supportive evidence that firms hold less cash when EPU is high. We further show that the market discounts excess cash holdings under high policy uncertainty, but this negative effect is mitigated by stronger investor protection, better freedom of press, and better government quality.     

Labor Union Effect on Corporate Cash Holdings and Their Marginal Value

By using panel data from Korean listed firms, we find that unionized firms strategically hold less cash to enhance their bargaining power against labor unions. We also find that unionized firms are likely to reduce the marginal value of their cash holdings, thereby decreasing shareholder value from the agency theory perspective. This finding complements the agency theory argument that managers tend to waste corporate resources by hoarding cash, particularly when faced with increased information asymmetry and financial constraints. Overall, our results suggest that information-related financial constraints and agency problems are likely to co-exist in unionized firms.     

Corporate governance as religion

This paper, examining five different corporate governance topics, considers whether certain corporate governance reforms—perhaps because of the passion with which their advocates advance them—have increasingly become articles of faith rather than matters of intellectual analysis and empirical evaluation. The paper proceeds on the premise that good corporate governance is very important, but that it is not always easy to determine whether any particular proposed reform actually constitutes good or bad corporate governance. It concludes that sound corporate governance reforms can only be forged on the anvil of close and rigorous examination—wherever that examination might lead.      

中国证券公司退出机制问题探讨

随着我国证券市场的规范发展,由于历史原因,部分证券公司积聚的风险日益凸显,高风险证券公司的风险处置和市场退出,成为中国证券市场面临的重要课题。近年来,由于证券公司市场退出的法律机制不够完善,强制退出过程中存在行政主导、政策性强等问题。因此,完善我国证券公司市场退出机制,具有重要的现实意义。
