This study examines whether liquidity is priced in the Vietnamese stock market. We show that stock liquidity is an important factor that should be taken into consideration in pricing stock returns. Explaining power of asset pricing models is improved after the inclusion of liquidity factor. In addition, while Fama and French's (1993) three factors are significant in the Vietnamese stock market, Carhart's (1997) momentum factor has very little effect. We also document that among various competing asset pricing models, the liquidity four‐factor model which includes market excess return, size, value and liquidity factor is the best model in the Vietnamese stock market. The results are robust to different measures of liquidity, as well as to both up‐ and down‐market conditions. 相似文献

In an attempt to assess the impact of currency depreciation on the trade balance, recent studies are employing disaggregated trade data to avoid aggregation bias. However, since import and export prices are not available at disaggregated level, recent studies are using export and import values rather than their volumes so that they can establish direct relation between inpayments and the exchange rate as well as between outpayments and the exchange rate. This study explores the experience of Malaysia. Bilateral inpayments and outpayments models are estimated between Malaysia and her 14 trading partners using quarterly data and bound testing approach to cointegration. The results show that while real depreciation of the ringgit has short-run effects, in the long-run it increases Malaysia's inpayments from only five trading partners. 相似文献

This study explores whether the credit risk anomaly exhibits option-like behaviour similar to the momentum anomaly. It finds that the inverted credit risk spread indeed displays option-like behaviour in bear market states. Unlike a momentum portfolio, which is effectively a short call option on the market, an inverted credit risk portfolio appears to be a long call option on the market. 相似文献

This paper examines the impact of economic policy uncertainty on firm-level capital investment, by not only delving into the long-term investment-uncertainty relation like previous studies, but also analyzing the short-term investment-uncertainty relation for the U.S. market. The empirical investigations show that firms decrease short-term, long-term, and total firm investments when encountering higher economic policy uncertainties. The research also explores the non-linear investment-uncertainty relation based on various theories. Our findings present a U-shaped relationship between short-term, long-term, and total investments and uncertainties. Policy implications are provided from our empirical results. 相似文献

我国期货市场亟需期货投资基金 总被引:2,自引:0,他引:2
我国期货行业自进入21世纪以来取得了飞速发展,无论品种规模还是成交量都已位居世界前列,然而,在国外已经成为期货市场主力的期货投资基金在我国却难觅其踪。期货投资基金可以优化和改善投资组合,规避股市系统性风险,实现专家理财保护中小投资者利益。实际上,从市场规模、运作现状、风险控制、资金充裕度以及证券投资基金在我国发展的成功经验来看,我国已基本具备设立期货投资基金的基础。但期货投资基金毕竟是一个高风险的投资工具,国内对它的研究还比较薄弱,法律体系和监管机制仍待完善,产品的种类和活跃程度仍待加强,在基金公司的设立方式上仍需谨慎选择,对于期货投资基金亟需的高端综合型人才的培养都是我国急需解决的问题。 相似文献

The vast majority of empirical research on calendar anomalies has studied financial markets in countries where the Western calendar is used. This article investigates day of the week effects in Saudi Arabia’s stock market, where an Islamic calendar is used and where Saturday is the first working day of the week over the sample period considered. The Saudi stock market is the largest in the Gulf region, and we consider both total market data (the TASI index) and data for 15 sector indices. Our investigation reveals the existence of a positive Saturday effect, which contrasts with the results on first day of the week effects that are typically obtained for Western calendar markets. 相似文献

中国社保基金入市的安全性及其监管 总被引:1,自引:0,他引:1
社保基金进入证券市场改变了过去投资渠道狭窄、资金运用率低的状况,同时为证券市场提供了稳定的资金来源。但由于证券市场本身的缺陷及波动风险,以及社保基金入市的管理体制不完善及相关法律制度不健全,社保基金入市也面临着巨大的风险。因此应吸取国际先进经验,通过设置合理入市比例、合理选择投资品种和基金管理人以及完善信息披露机制、准备金制度等,建立安全投资机制,以最大限度地防止和控制社保基金的投资风险。 相似文献

ABSTRACT This paper is the first study to present firm-level evidence that the time-series momentum (TSMOM) strategies with look-back-period k of 10 to 200 days outperform the buy-and-hold strategy (BH) on individual stocks in the Chinese stock market. We document that the optimal k* generating the best performance is different across assets and varies over time. We hence propose a model to predict the asset-specific and time-dependent k*, and examine the performance of the TSMOM strategies with the predicted k*. Our analysis shows that using the time-varying predicted k* substantially improves the predictability of the TSMOM strategies. Our new model and findings shed the light on trading strategy for both academia and applied investment practitioners. 相似文献

服务业外商直接投资流入与房地产市场风险研究——以上海为例 总被引:1,自引:0,他引:1
我国房地产价格的持续攀升引起政府和社会的极大关注,其中以北京、上海等一线城市尤为典型。影响我国房价持续快速攀升的因素众多,着眼于服务业外商直接投资的流入对上海房地产价格的冲击及可能存在的市场风险展开分析。结果显示,外商直接投资的变动对上海房地产价格波动不构成显著性影响。这表明,目前我国政府的宏观调控措施成功规避了FDI流入可能产生的资产泡沫风险。但是,面对当前通货膨胀预期全面显现、房价居高不下的现实,政府应继续对各类以FDI名义的短期资本流动加以必要的管控;将利率维持在一个较为合理的低水平,以熨平国内宏观经济增长的大幅波动,确保房地产市场的稳定健康发展。 相似文献

Using ideas from the endogenous growth literature, we present a model of the endogenous determination of productivity growth based on individual worker decisions about human capital investment. We calibrate a version of the model to match long run growth facts from the US and study the business cycle properties of this model. This approach offers improvements along several dimensions over standard exogenous growth methodologies. Most importantly, our stochastic endogenous growth model generates much greater serial correlation in output growth and labor supply volatility relative to its real business cycle counterpart. We conclude that using the extra discipline of reproducing the trend productivity growth features of the data endogenously constitutes an important missing component from the real business cycle approach. 相似文献
