Estimation and analysis of the Hurst exponent for Australian stocks using wavelet analysis 用小波分析估计和分析澳大利亚股票的赫斯特指数
Pub Date : 2008-01-01 DOI: 10.1080/17446540701367444
R. Brooks, E. Maharaj, B. Pellegrini
This article presents an estimation and analysis of the Hurst exponent for Australian stocks using the wavelet technique. Consistent with Mulligan's (2004) study of US technology stocks, we find that the Hurst exponent varies over the cross-section of stocks. We also analyse Mulligan's (2004) and our data and find that beta can explain some of the cross-sectional variation in the Hurst exponents. However, we find that our results are not robust to filtering out the short range dependence in the data.
本文利用小波技术对澳大利亚股票的赫斯特指数进行了估计和分析。与Mulligan(2004)对美国科技股的研究一致,我们发现赫斯特指数在股票的横截面上是不同的。我们还分析了Mulligan(2004)和我们的数据,发现beta可以解释赫斯特指数的一些横截面变化。然而,我们发现我们的结果对于滤除数据中的短距离依赖并不具有鲁棒性。

Consumption, wealth and expected stock returns in Australia: some further results 澳大利亚的消费、财富和预期股票回报:一些进一步的结果
Pub Date : 2008-01-01 DOI: 10.1080/17446540701262843
L. Fisher
This article re-examines the evidence that cay, the residual from a cointegrating regression of consumption on labour income and household wealth, is a useful predictor of excess stock returns in Australian data. In recursive samples beginning in 1976:q4 and ending from 1990:q1 to 2003:q1, cay is a strong predictor of excess returns. In samples that end thereafter, cay loses its predictive power for returns. This is due to a break-down in the cointegrating relation among consumption, labour income and household wealth following recent developments in the housing and stock markets.
本文重新审视了证据,即消费对劳动收入和家庭财富的协整回归的残差,是澳大利亚数据中超额股票回报的有用预测因子。在从1976年第4季度开始到1990年第1季度至2003年第1季度结束的递归样本中,day是超额回报的有力预测因子。在此后结束的样本中,day失去了对回报的预测能力。这是由于最近住房和股票市场的发展打破了消费、劳动收入和家庭财富之间的协整关系。

Do acquirer company returns improve after a takeover? Empirical evidence for Australia 收购后收购方公司的收益是否有所改善?澳大利亚的经验证据
Pub Date : 2008-01-01 DOI: 10.1080/17446540701367493
Stuart Dullard, K. Hawtrey
This article investigates the returns of acquirer companies in the wake of corporate takeovers. The study tests the post-takeover returns of Australian acquirer firms during the period 2001 to 2003, using two alternative benchmark models. We find evidence that acquirer companies outperform the market benchmark in the three years following the takeover. We also find that takeovers improve the share price performance of such companies relative to their pre-takeover history.
本文研究了企业收购后收购方的回报。本研究使用两种不同的基准模型,对2001年至2003年期间澳大利亚收购方的收购后回报进行了测试。我们发现证据表明,收购公司在收购后的三年内表现优于市场基准。我们还发现,相对于收购前的历史,收购改善了这些公司的股价表现。

Estimating the uncertainty of relative risk aversion 估计相对风险厌恶的不确定性
Pub Date : 2008-01-01 DOI: 10.1080/17446540701335474
Karl-Heinz Tödter
This note reports estimates of the coefficient of relative risk aversion, using a method recently proposed by Azar (2006). In contrast to his work, the complete information of US stock return data over the period 1926 to 2002 is utilized. Moreover, a bootstrap procedure is applied to estimate the associated uncertainty. Point estimates close to 3.5 are obtained. However, ranging from 1.4 to 7.1, the 95% confidence interval is wide.
本文使用Azar(2006)最近提出的一种方法,报告了相对风险厌恶系数的估计。与他的工作相反,他使用了1926年至2002年期间美国股票回报数据的完整信息。此外,采用自举法估计了相关的不确定性。得到接近3.5的点估计。然而,从1.4到7.1,95%置信区间很宽。

Transmission of shocks among health care stock index returns 传导冲击中医疗保健类股票指数回升
Pub Date : 2008-01-01 DOI: 10.1080/17446540701416399
B. Ewing, Jamie B. Kruse, M. A. Thompson
This article examines the transmission of shocks among different sectors of the health care industry using financial market data in an excess-return model. As suggested by the nature of the reimbursement schemes, we find a significant linkage between the payor and product sectors. A significant and stronger linkage between the payor and provider sector exists. Given its competitive and well-diversified operating environment, the product sector may be better positioned to absorb shocks from the other health care sectors.
本文使用金融市场数据在一个超额回报模型中检验了冲击在医疗保健行业不同部门之间的传导。正如偿还计划的性质所表明的那样,我们发现付款人和产品部门之间存在重大联系。付款人和提供者部门之间存在着重要和更强的联系。鉴于其竞争激烈和经营环境多样化,产品部门可能更有能力吸收来自其他保健部门的冲击。

The dynamic relationships between gold futures markets: evidence from COMEX and TOCOM 黄金期货市场之间的动态关系:来自COMEX和TOCOM的证据
Pub Date : 2008-01-01 DOI: 10.1080/17446540701262868
Hui-Na Lin, Shu-Mei Chiang, Kun-Hong Chen
This study employs a bivariate GARCH model to examine the dynamic relationships between two gold futures markets (COMEX and TOCOM) before and during gold's recent uptrend of the past few years. Results show that the performance of COMEX is better than TOCOM. However, TOCOM leads COMEX in the mean return. Volatility transmission effects exist in both COMEX and TOCOM. While the responses to good news and bad news are symmetrical in TOCOM, they are asymmetric in COMEX.
本研究采用双变量GARCH模型来检验两个黄金期货市场(COMEX和TOCOM)在过去几年黄金最近上涨趋势之前和期间的动态关系。结果表明,COMEX的性能优于TOCOM。然而,东交所在平均回报率上领先COMEX。COMEX和TOCOM均存在波动传导效应。虽然TOCOM对好消息和坏消息的反应是对称的,但COMEX对好消息和坏消息的反应是不对称的。

Underpricing of initial public offerings in Bangladesh 孟加拉国首次公开募股定价过低
Pub Date : 2008-01-01 DOI: 10.1080/17446540701222383
T. Hasan, Shakil Quayes
The present study provides a comprehensive analysis of the short-run underpricing of initial public offerings (IPO) in Bangladesh and attempts to identify the factors which contribute to such underpricing in this heavily regulated underwriting market. Using a sample of 90 IPOs issued during the short-lived stock market boom in the mid-nineties, we show that increased ownership stake and foreign participation lowers the magnitude of underpricing.
本研究对孟加拉国首次公开募股(IPO)的短期定价过低进行了全面分析,并试图确定在这个受到严格监管的承销市场中导致这种定价过低的因素。我们以90年代中期短暂的股市繁荣期间发行的90次ipo为样本,表明股权和外资参与的增加降低了定价过低的程度。

Emerging markets mutual funds: regional exposure and stock selection ability 新兴市场共同基金:区域敞口与选股能力
Pub Date : 2008-01-01 DOI: 10.1080/17446540701367477
Javier Rodríguez, J. Torrez
The regional exposure and stock-selection ability of emerging markets mutual funds is empirically examined during the 2001 to 2005 time period. This sample of funds shows a clear preference towards the Asian markets and as a group show evidence of poor stock-selection ability. When the sample is partitioned between surviving and nonsurviving funds, only the subgroup of surviving funds show evidence of positive stock-selection ability.
本文对2001 ~ 2005年新兴市场共同基金的区域风险敞口和选股能力进行实证检验。这些基金样本显示出对亚洲市场的明显偏好,作为一个整体,它们的选股能力较差。当样本被划分为生存基金和非生存基金时,只有生存基金的子组表现出积极的选股能力。

In this article the long memory and nonlinear properties of share prices in the UK's stock exchange and alternative investment markets are explored. The results suggest that the most commonly traded shares exhibit long memory. Thus, the validity of market efficiency is questioned.
