中国股市涨跌停板对投资者交易行为的影响

利用A股市场的日内高频数据,研究我国股市涨跌停板制度是否存在"磁吸效应",从而判断涨跌停板的存在是否会影响投资者在面临个股较大涨跌幅时的交易行为.研究结果表明:一,我国A股市场涨跌停板的设定并不会导致投资者流动性风险的增加;二、投资者观察到股价大幅波动时会比较谨慎,涨跌停板的存在抑制了股价波动的进一步增大;三,临近收盘时,如果股价已下跌了较大的幅度,投资者的损失规避交易会造成股价的继续下跌.     

涨跌停板制度对我国期货市场流动性影响的实证研究

涨跌停板是当前很多国家都采用的价格稳定机制。实行涨跌停板制度的目的，在于通过利用人工干预的方法，减缓市场价格波动的剧烈程度，尤其在投机过度和交易过热的市况下．适时实施涨跌停板中断交易，能够使交易者恢复理智．保持冷静的头脑，正确对待价格的涨落．防止被人操纵．有利于保障市场的正常运行。     

股票停牌、涨跌停与ETF定价效率——基于上证50ETF日度数据的实证研究

本文应用中国股市2007年至2011年的数据,研究了上证50ETF市场价格和基金净值的相关关系,以及折溢价水平及其影响因素。基于ETF的申购赎回和交易机制,在成分股涨跌停板和停牌期间,由于ETF二级市场价格具有价格发现功能,ETF市场价格可能较大偏离(形式上的)ETF净值,造成ETF的异常折溢价,而此类异常折溢价并不是真正的套利机会。另外,上证50ETF的市场价格与基金净值存在显著同步变动的关系;在涨跌停板和停牌期间之外,上证50ETF的折溢价水平低于套利所需的交易成本。本文研究表明,上证50ETF具有较高的定价效率。     

对我国证券及期货市场涨跌停板制度的相关研究梳理一一个文献综述

从1990年12月19日上海证券交易所揭牌营业到今天,我国证券市场已经走过23年的历程,作为一个新兴的资本市场,油有条件借鉴发达国家成熟的市场经验和对市场的监管模式,一开始就对股票的日交易价格采用限制,实施涨跌停板制度.本文试图通过从历史沿革、与国外相似制度对比的角度出发,对我国采取的股市涨跌停板制度作一个梳理.

本文基于沪铜期货,通过非参数统计的方法实证研究了涨跌停制度对价格日间行为的影响。研究发现,在样本期内,涨跌停板制度造成了一定程度的波动溢出效应,十分显著的流动性干扰效应,同时涨停板造成十分显著的价格发现延迟效应,跌停板的价格发现延迟效应不显著。基于研究结论,给出对于沪铜合约涨跌停板制度的建议。

中国股票市场的操纵与监管:模拟分析

利用模拟的方法研究了操纵所造成的股价行为以及可以采取的监管措施.结果表明,模拟出来的股价行为符合实证研究的结果;涨跌停板等监管措施无法对操纵产生本质影响,必须引入理性投资者.     

涨跌停板制度对股票市场价格发现及流动性的影响——基于沪深两市的实证研究

一、引言 自1987年美国股票市场发生危机以来,大多数国家的证券交易所都出台了控制股票价格过度波动的具体措施,其中措施之一即是采用了所谓的电闸制度,最常见的电闸制度包括两种即中止交易和实行涨跌停板制度.中止交易制度是指当价格波动超出一定范围时交易所有权暂时停止交易,通常不超过1-2小时,如纽约证券交易所、多伦多证券交易所等就采用这种交易制度.而涨跌停板制度则是指股价在一个交易日的波动范围不得超过上一个交易日的收盘价的一定幅度.为了维护股市稳定,中国的证券监管部门于1996年12月16日正式在上海、深圳两地股市实施了现行的涨、跌停板制度(幅度为10%).     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.

Bayesian Premium Rating with Latent Structure

We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.

The case for management history

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.     

The life and career of John Spence Ogilvy (1805-71), the first chartered accountant to emigrate to Australia

So far as the available evidence allows, this paper examines the life and career of John Spence Ogilvy, foundation member of the Society of Accountants in Edinburgh in 1854, who emigrated to Melbourne in 1856, but did not play a part in the development of an organized accounting profession in Australia. The paper also attempts to explain the gap of thirty-two years between the formation of the first accounting bodies in Edinburgh and Melbourne.
