Volatility spillovers across daytime and overnight information between China and world equity markets

This article explores the transmission of daytime and overnight information in terms of returns and volatility between Chinese and Asian, European and North American main stock markets. We propose a bivariate analysis with China as benchmark. By testing the constancy of the conditional correlations, we use an extended constant or dynamic conditional correlation GARCH model. The empirical findings show that across the daytime information transmissions, the relationships between China and Asian markets are closer than China and non-Asian markets, whereas through the overnight information transmissions these relationships are inverse. The analysis provides, before the crisis, that the overnight volatility spillover effects are from China to the United States and the United Kingdom. During the crisis, China affects the United Kingdom in terms of daytime volatility spillovers, whereas in terms of overnight volatility spillovers China affects the United States and is influenced by Japan. After the crisis, daytime volatility spillovers are from Taiwan to China, whereas the overnight volatility spillover effects are from China to the United States and the United Kingdom.     

American depositary receipts: An analysis of international stock price movements

With significant increases in private capital flows across the globe, there has been a rise in the US listing of foreign stocks as American depositary receipts (ADRs). In this study, we employ cointegration techniques and estimate error-correction (EC) models to examine the degree of integration between US and three foreign equity markets. We find that ADRs are cointegrated with ordinary shares trading in the UK, Japan, and Germany, which implies that for long-term investors, they are a substitute for ordinary shares. Our analysis of the dynamic relationships between ADRs and foreign equities suggest that both markets contribute information pertinent to portfolio valuation. However, the foreign markets are found to be the more important source of information.     

全球股票指数权重比较分析

优越的权重指标是构造成功的全球股票指数的基础,除了市值、GDP可用作权重外,本文提出出口额、进出口额、商品服务贸易额也可作为权重,并对该5种权重进行了比较分析,结论是:由于各国股票市场发展差异较大,市值权重太偏重发达国家;GDP适合作权重,但美国的权重太大,全球股指易受其左右,另汇率波动对权重的影响也不可忽视;出口额、进出口额与股市相关性强,汇率波动影响很小,权重结构比较理想,而进出口额尤佳。     

Bias and Precision of Estimates of Housing Investment Risk Based on Repeat-Sales Indices:A Simulation Analysis

A simulation analysis is reported which examines the bias and precision of estimates of housing investment risk based on small sample indices of housing returns. The trade-off between smoothing bias (due to temporal aggregation in the index) and noise bias (induced by random estimation error) is examined in the housing return total volatility, beta, and autocorrelation statistics of the index returns. The study compares the performance of three different specifications of the repeat-sales index, under assumptions of either an informationally efficient or inefficient housing market, and at two levels of estimation data availability. Findings suggest that regression-based repeated-measures indices may be useful at a more micro-level (e.g., at the neighborhood level or for specific housing types) than has hitherto been employed.

Non-tradable Share Reform and Tradable Shareholders＇ Wealth： An Event Study Analysis

On April 29, 2005, the reform of non-tradable shares was started. 46 companies were selected as the first and second batches of non-tradable share pilot reform, and among them 45 pilot companies finished their non-tradable share reform. This study examines the abnormal stock returns of the 45 pilot companies finishing their non-tradable share reform to determine whether tradable shareholders gain profits from this non-tradable share reform. By employing event study analysis, we find that tradable shareholders do gain profits from the non-tradable share reform. The average abnormal return of the 45 pilot companies was 10.62% on the resumption trading day after they finished their non-tradable share reform, which was statistically significant. We also find that the average abnormal return of high-compensation package group is significantly higher than that of low-compensation package group.
