我国证券交易前端控制制度的历史演进及发展趋势   总被引:1,自引:0,他引:1  
前端控制是交易所在交易方面进行自律监管的重要手段。前端控制是中国证券市场的特有制度,是对传统监管模式的重大创新。根据中国市场结构的特点,前端控制实质上将监管关口前移,分担了盘中监控和事后处理的监管压力,弥补了资格准入的不足,完善了交易所自律的监管体系。对前端控制的经济学分析表明,前端控制具有透明度高与全面性强两大优势,符合监管机构稳定市场的需要。我国资本市场发展尚不成熟,且金融危机后全球金融改革的大趋势是加强监管,因此,在可预见的未来,监管机构将进一步加强前端控制,以此保持我国资本市场的稳定发展。  相似文献

We test for the performance of a series of volatility forecasting models (GARCH 1,1; EGARCH 1,1; CGARCH) in the context of several indices from the two oldest cross-border exchanges (Euronext; OMX). Our findings overall indicate that the EGARCH (1,1) model outperforms the other two, both before and after the outbreak of the global financial crisis. Controlling for the presence of feedback traders, the accuracy of the EGARCH (1,1) model is not affected, something further confirmed for both the pre and post crisis periods. Overall, ARCH effects can be found in the Euronext and OMX indices, with our results further indicating the presence of significant positive feedback trading in several of our tests.  相似文献

We examine the dynamic relation between returns, volume, and volatility of stock indexes. The data come from nine national markets and cover the period from 1973 to 2000. The results show a positive correlation between trading volume and the absolute value of the stock price change. Granger causality tests demonstrate that for some countries, returns cause volume and volume causes returns. Our results indicate that trading volume contributes some information to the returns process. The results also show persistence in volatility even after we incorporate contemporaneous and lagged volume effects. The results are robust across the nine national markets.  相似文献

Abstract

This paper investigates the short-term dynamics of stock returns in an emerging stock market namely, the Cyprus Stock Exchange (CYSE). Stock returns are modelled as conditionally heteroscedastic processes with time-dependent serial correlation. The conditional variance follows an EGARCH process, while for the conditional mean three nonlinear specifications are tested, namely: (a) the LeBaron exponential autoregressive model; (b) the Sentana and Wadhwani positive feedback trading model; and finally (c) a model that nests both (a) and (b). There is an inverse relationship between volatility and autocorrelation consistent with the findings from several other stock markets, including the US. This pattern could be the manifestation of a certain form of noise trading namely positive feedback trading or, momentum trading strategies. There is little evidence that market declines are followed with higher volatility than market advances, the so-called ‘leverage effect’, that has been observed in almost all developed stock markets. In out of sample forecasts, the nonlinear specifications provide better results in terms of forecasting both first and second moments of the distribution of returns.  相似文献

银行业危机:金融泡沫视角的分析   总被引:2,自引:0,他引:2  
自20世纪80年代以来,银行业危机爆发越显频繁。然而,通过对银行业危机内部形成机理分析可以发现,银行业危机的爆发其实是伴随着金融泡沫的形成与破灭这一过程的。在金融泡沫的形成过程中,银行往往会给一些高风险行业发放贷款,从而增加银行经营风险;而在金融泡沫破灭之后,这将直接或间接地导致银行产生大量的不良贷款,从而使银行业危机最终爆发。因此,我国应尽快化解国有商业银行的不良资产;完善银行微观治理结构;建立和完善金融监管机制。  相似文献

最小价格变化单位是买卖价差的底线,设置过高会人为地提高买卖价差的水平,增加交易费用;过低又会降低市场深度,增加交易谈判成本,影响交易效率。对最优价格升降档位的设定,要综合考虑精度要求、合约乘数、交易谈判成本和实际买卖价差水平等因素;而以实际买卖价差的底线作为最小价格升降档位,能较好地避免人为抬高买卖价差的情况出现。  相似文献

Abstract

Although extensive literature has suggested that investor sentiment may be one of the most important factors in explaining investor trading frequency and trading strategies, how individual investors are significantly influenced by sentiment remains underexplored. The feature of numerous individual investors in the Taiwan stock market provides an avenue to examine the relationship of investor sentiment to trading frequency and positive-feedback trading according to intraday data. Using a vector autoregression model to measure feedback trading in one-minute intervals, we find that trading frequency appears to increase in periods of rising market, suggesting that investor sentiment–driven trading increases market trading frequency without relying on past experiences to conduct trading behavior.  相似文献

This study documents the negative relationship between foreign ownership and the future volatility of Indonesian stocks. The calming effect of foreign ownership is present before, during, and after the Asian financial crisis. It is independent of gross and net foreign trading and the stock's historical volatility. The effect increases with the level of foreign holdings. The findings are contrary to the volatility impact of institutional ownership in developed markets, and indicate the presence of different economic mechanisms leading to the opposite volatility impact from foreign ownership and foreign trading.  相似文献

经济开放进程中金融危机冲击比较研究   总被引:4,自引:1,他引:4  
亚洲金融危机和美国次贷危机对中国经济产生了明显的影响,但在经济开放进程中这两次危机冲击特点和结果均有所不同。本文对开放进程中金融危机向国内传导的渠道进行分析,利用指标对比分析法、干扰模型、脉冲响应以及方差分解技术分析比较了两次金融危机对我国冲击的不同影响机制。研究结论表明,在经济开放进程中,美国次贷危机对国内经济的冲击要远超于亚洲金融危机;在资本项目没有完全开放条件下,国际贸易渠道越来越成为国际金融危机冲击向国内传导的重要渠道;尽管经济开放增加了金融风险,但良好的制度设计和金融风险管理手段的加强,使金融危机通过金融渠道传导而产生的冲击波有所降低。  相似文献

This study examines institutional herding in the ADR market between 1985 and 1998. We find a significant positive relation between changes in institutional ownership and ADR returns over the same period. The positive relation persists after we control for the momentum effect in the US stock markets. We also find that in the ADR market, past winners (losers) in the herding period continue to be the winners (losers) in the post-herding period. The lack of a returns reversal suggests institutional herding is related to momentum trading. However, the positive relation between institutional ownership changes and ADR returns remains after controlling for momentum trading in the ADR market. Our results also rule out that positive feedback trading is related to institutional herding in the ADR market.  相似文献

Using NASDAQ trade and Reuters news data, I show that the response of aggressive non‐high‐frequency traders (nHFTs) to news is stronger than that of aggressive high‐frequency traders (HFTs). Classifying news into quantitative (“hard”) and less quantitative (“softer”) news, the trading response of aggressive nHFTs to softer news exceeds HFTs’ response. Positive news elicits greater return and nHFT responses than negative news during the 2008 financial crisis period. As this phenomenon persists even after excluding the 2008 short‐sale ban, the results support the hypothesis of nHFTs exhibiting stronger asymmetric responses during crisis periods.  相似文献

We assess the state of knowledge about crisis risk and its implications for risk management. Data that became available after the global financial crisis show that some types of crises are predictable when accounting for interactions between risks. However, other types of crises do not seem predictable. There is no evidence that the frequency of economic and financial crises is increasing. While data show that an economic crisis is more likely following a political crisis, there is no comparable evidence for climate events. Strategies that increase firm operational and financial flexibility reduce the adverse impact of crises on firms.  相似文献

西方金融危机的深层透视及其启示   总被引:1,自引:0,他引:1  
引起当前西方经济走向萧条的真正原因不是政策失误、监管疏忽和金融投机,不是次贷危机引起金融危机、金融危机引起经济危机。社会化的产品及其所包含的剩余价值为资本家个人所占有,决定了生产与消费脱节的可能和必然,决定了投资不足和投资需求由热到冷,触发生产过剩并引起经济危机。现代金融资本通过对利润的有力掠夺,进一步破坏消费市场,通过诱导过量生产、制造虚假繁荣,引领经济循环。只有建设社会主义经济方式、合理的微观企业制度基础和科学的金融体制才能避免金融危机、经济危机和停滞衰退。  相似文献
