Theories predict that launching index futures could affect the price informativeness for the underlying stocks. We test this
hypothesis by taking advantage of the introduction of the Nikkei 225 futures contracts in Singapore on September 3, 1986.
Employing two alternative statistical methods applied to both daily and weekly data, we find that, following the listing of
the index futures, returns become significantly more random and less predictable for the underlying stocks, even after controlling
for concurrent marketwide shifts. These findings suggest improved price informativeness for the underlying stocks, which is
further corroborated by their higher trading volume following the event.

荒原在不同时代的文学作品中被赋予了不同的象征意义。在哈代的小说《还乡》中亦多次出现荒原主题,荒原是《还乡》的灵魂。哈代通过小说《还乡》表达了回归荒原、回归自然以及人与自然和谐统一的生态思想。 相似文献

We investigate the effects of the 2016 Paris Climate Agreement on the German stock market by considering the impact of 20 announcements pertaining to the Agreement on 17 industries. The event study methodology is used for this purpose, together with several robustness tests, such as the nonparametric rank test and non-parametric conditional distribution approach. The change in systematic risk following the announcements is captured by using various risk models. In general, we find that the Paris Climate Agreement is achieving its objectives in the short run. Our results show that the announcements affected polluting industries in terms of risk and return. Furthermore, we observe two distinct diamond risk structures when (1) Conference of the Parties (COP) 21 took place, and (2) the Agreement came into force. 相似文献

This paper tests asset pricing implications of the investor attention shift hypothesis proposed in theoretical work. We create a novel proxy for the dynamics of inattention towards firm-specific information and explore its impact on prominent return anomalies. As hypothesized and with all else equal, the proxy positively predicts the post-earnings announcement drift as well as the profitability of pairs trading, and negatively predicts the success of momentum strategies. Taken together, our findings highlight the importance of time-varying investor attention allocation for the price discovery process. 相似文献

This paper utilizes deep learning approach widely documented in artificial intelligence, and proposes an investor-sentiment indicator (ISI) that is consistent with the purpose of forecasting stock market returns. We find that ISI is positively correlated with future stock market returns at a monthly frequency, but negatively associated with subsequent returns over a longer horizon. Moreover, ISI outperforms other well-recognized predictors both in and out of sample, and can predict cross-sectional stock returns sorted by industry. We also show a positive association between monthly ISI and dividend growth rate, which indicates that investors’ expectations about future cash flows may contribute to the return predictability of ISI. 相似文献

In the presence of transactions costs, no matter how small, arbitrage activity does not necessarily render equal all riskless rates of return. When two such rates follow stochastic processes, it is not optimal immediately to arbitrage out any discrepancy that arises between them. The reason is that immediate arbitrage would induce a definite expenditure of transactions costs whereas, without arbitrage intervention, there exists some, perhaps sufficient, probability that these two interest rates will come back together without any costs having been incurred. Hence, one can surmise that at equilibrium the financial market will permit the coexistence of two riskless rates that are not equal to each other. For analogous reasons, randomly fluctuating expected rates of return on risky assets will be allowed to differ even after correction for risk, leading to important violations of the Capital Asset Pricing Model. The combination of randomness in expected rates of return and proportional transactions costs is a serious blow to existing frictionless pricing models. 相似文献

Fifteen Chinese H-shares listed on the Stock Exchange of Hong Kong are cross listed as ADRs on the NYSE. We empirically determine the role of security specific liquidity associated with those ADRs and their underlying H-shares on return spreads, differences between the returns on ADRs and their corresponding H-shares after controlling for ADRs and H-shares excess market returns and their respective price inverses denoting conditional betas. We use three proxies for liquidity, trading volume, turnover, and illiquidity (Amihud, 2002) and find that only trading volume and turnover are consistent determinants of return spread for the majority of Chinese ADRs with primary listing in Hong Kong Stock Exchange (SEHK). We use a switching regression model and find that the model parameter estimates are not stationary and change, often drastically between pre and post 2000 and 2003. Further tests using Bai Perron indicate return spreads data as non-stationary with multiple regime changes during the sample period. Further the causes of non-stationarity seem to be largely security specific and not driven by broad market swings in either market. 相似文献

Using data from the Asian country ETFs and their MSCI indices, this paper examines whether trading location affects return comovements and diversification benefits. Our empirical results show that the magnitude of return comovements for the Asian country ETFs is higher than the corresponding MSCI indices. Moreover, our empirical findings indicate that the factors, including investor sentiment, market conditions, and economic fundamentals of the U.S. market, have greater effects on the return comovements for the Asian country ETFs than their underlying MSCI indices. Finally, the evidence presents a higher diversification benefit for the Asian MSCI indices than the Asian country ETFs. 相似文献

基于永续盘存法,运用双曲线效率递减的“年龄 效率”模式首次系统估算得到“一带一路”沿线50个国家1995年至2018年的资本投入,并进一步对沿线国家资本投入及其资本回报率的时空演变特征进行分析。研究表明:沿线国家资本投入水平整体呈波动中上升趋势,尤其在2007年后整体呈现资本投入积累加速的典型特征;区域间及区域内部各国之间资本投入差异较大,其中东亚地区积累水平最高、南亚地区次之、东欧地区和西亚地区水平相近、中亚地区积累水平最少;“一带一路”沿线国家整体资本产出比水平呈现下降特征,各地区投资效率得到不断改善;“一带一路”沿线国家资本回报率表现出较强“顺周期性”特征,且亚洲地区资本投入回报率整体高于欧洲地区,区域间资本回报率逐步收敛的趋势不容忽视。 相似文献
