金融机构稳健经营关系金融体系的整体稳定,对其股价进行研究对中央银行更好制定货币政策、维护金融稳定具有重要意义。通过股票联动性和波动性可以找出各机构间的影响路径。为找出核心金融机构及其风险传导路径,维护金融体系稳定,本文选取2014—2023年全国36家上市金融机构股票每日收盘价数据,建立收益率网络和DCCMVGARCH模型波动率网络,对各金融机构股票的联动性和波动性进行实证分析。研究发现,我国金融机构股票市场较为成熟,金融机构股票影响力的大小主要取决于投资者对其的熟悉度和信任度,以及与股市相关的业务发展程度;利率市场化是不可避免的潮流趋势,银行类金融机构的影响力始终强劲,但证券业及保险、信托行业类金融机构在股票市场上的关联性也在不断增强,逐渐扩大影响力。金融监管部门制定政策时可着重关注影响力最大的金融机构及其风险传播路径,防范风险,维护金融稳定。 相似文献

本文基于复杂网络理论,构建了银企间通过信贷和产权关系形成的金融网络,利用信贷资产的信用转移矩阵和银行的资产负债表建立了银企间信贷风险传染的动态模型。通过理论推导和仿真模拟,本文系统分析了影响风险传染规模的各种因素以及系统重要性银行和不同风险传染渠道在信贷风险传染中所起的作用。研究表明:初始经济冲击、资产的市场流动性和违约损失率与风险传染效应间存在正相关关系,网络规模与风险传染呈现非单调的关系;随着网络规模的扩大,风险传染效应先增加后减小;系统重要性银行受到冲击时引发的传染规模远大于一般银行;随着金融系统总损失的不断增加,银行间的风险传染渠道逐渐居于主导地位。 相似文献

香港股市与内地股市的联动性研究 总被引:6,自引:0,他引:6
本文分3个阶段考察了香港回归以来,香港股市和内地股市之间的联动关系及其变化。协整分析表明,香港股市和内地股市之间存在长期的均衡关系,这种均衡关系在内地资本市场实行股权分置改革后更趋于稳定。Granger因果检验表明,香港回归以来香港股市和内地股市之间的引导关系在经历B股开放和股权分置改革后发生了变化。脉冲响应函数分析从动态的角度进一步验证了香港股市和内地股市之间的引导关系及其变化,并深入分析了单个变量的波动或冲击对其自身及另一变量的影响程度。 相似文献

We study the co-movement between innovative financial assets (i.e., FinTech-related stocks, green bonds and cryptocurrencies) and traditional assets. We construct a co-movement mode transmission network and discuss the network topology during the pre-COVID-19 and COVID-19 periods. We extract network topology information to predict the co-movement mode by machine learning algorithms. We further propose dynamic trading strategies based on the co-movement mode prediction. The empirical results show that (i) the evolution of co-movement is dominated by some key modes, and the mode transmission relies on intermediate modes and shows certain periodicity; (ii) the co-movement relationships are influenced by the ongoing COVID-19 outbreak; and (iii) the novel approach, which combines complex network and machine learning, is superior in co-movement mode prediction and can effectively bring diversification benefits. Our work provides valuable insights for market participants. 相似文献

We analyse Chinese RMB co-movements with the currencies of other developing economies using daily data from January 1, 2006 to December 31, 2020. We find that the RMB plays an important role in East Asia & Pacific. Bilateral trade significantly increases the probability of RMB co-movements with other currencies while inflation differential decreases it. Additionally, the currencies of the economies that are more inclined to adopt a pegging system are less likely to co-move with the RMB. We further divide the sample into three sub-periods based on two major China’s currency reforms and the results are consistent with our main finding. We also investigate the nonlinear determinants of RMB co-movements in high and low volatility regimes, respectively, and show the different patterns. Last but not least, we find that RMB currency swap and the Belt and Road Initiative amplify RMB co-movements in larger and more developed economies. 相似文献

This paper examines the directional spillover between crude oil prices and stock prices of technology and clean energy companies. The study uses the daily data over the period from May 2005 to April 2015. The estimated results exhibit following empirical regularities. First, it appears that technology stocks play vital role in the return and volatility spillovers of renewable energy stocks and crude oil prices. Second, technology (PSE) and clean energy indices (ECO) are the dominant emitters of return and volatility spillovers to the crude oil (WTI) prices. Third, the time and event-dependent movements are well captured by the directional spillover approach. Fourth, the application of directional spillover method seems to be more advantageous than MGARCH models as it not only establishes the inter-variables return and volatility spillovers but also helps in identifying direction of spillover through calculation of pairwise net spillovers. Last, the dynamic hedging results suggest that clean energy index can provide a profitable hedging opportunity in combination with crude oil futures than technology index. Many new findings further discussed and analysed. 相似文献

This article examines the time-varying spillover and its implications on hedging and portfolio diversification for clean energy equities (WilderHill New Energy Global Innovation Index (NEX)) with technology stocks (PSE), four energy sub-indices of Standard & Poor Goldman Sachs Commodity Index (S&P-GSCI) viz., Crude oil, Brent crude oil, Gasoline and Heating oil and three major global equities indices represented by the USA, Europe, World, Dow-Jones Islamic Market Index (DJIMI) along with USD-Euro exchange rate. We find that in a mixed portfolio set-up, the inclusion of NEX in energy portfolio provides better diversification and risk reduction benefits for hedgers and portfolio managers. 相似文献

Literature suggests assets become more correlated during economic downturns. The COVID-19 crisis provides an unprecedented opportunity to investigate this considerably further. Further, whether cryptocurrencies provide a diversification for equities is still an unsettled issue. We employ several econometric procedures, including wavelet coherence, and neural network analyses to rigorously examine the role of COVID-19 on the paired co-movements of four cryptocurrencies, with seven equity indices (matching countries particularly impacted by COVID-19). Our period of study includes one year prior to the onset of COVID-19, and one year during the pandemic, extending deeper into the pandemic period (February 2021) than most previous studies. We find co-movements between cryptocurrencies and equity indices gradually increased as COVID-19 progressed. However, most of these co-movements are either modestly positively correlated, or minimal, suggesting cryptocurrencies in general do not provide a diversification benefit during either normal times or downturns. An exception, however, is the co-movement of tether. Tether co-moves negatively with equities to an economically significant degree, both pre COVID-19, and considerably more during COVID-19. Co-movements between tether and equity indices spiked sharply during identified waves of the pandemic. Tether appears to be an important safe haven during times of market turmoil, consistent with investors seeking USD liquidity during periods of volatility. 相似文献

In this paper, we study the relative performance of value versus growth strategies from the perspective of stochastic dominance. Using half a century US data on value and growth stocks, we find no evidence against the widely documented fact that value stocks stochastically dominate growth stocks in all three orders of stochastic dominance relations over the full sample period as well as during economic boom (good) periods. However, we observe no significant stochastic dominance relation between value and growth stocks during recession (bad) periods, which is inconsistent with the risk-based predictions but is better explained by behavioural models. 相似文献

We fit a factor model to two monthly panels of deflated prices of energy, metals and agricultural commodities. Prices consistently display a tendency to revert towards the factor, though the speed of reversion to the factor is slow. Using both in- and out-of-sample metrics, we compare the factor model to that of a “no change” model and to two simple models that tie changes in commodity prices to percentage change in either global industrial production or the U.S. dollar. The factor model does relatively well at long (12 month) horizons. In terms of commodities, the factor model's performance is best for energy prices, worst for metals, with agricultural prices falling in between. 相似文献

This paper analyses interdependence between the returns of specific energy and non-energy commodities and equities using (i) Thick Pen Measure of Association (TPMA) and (ii) Multi-Thickness Thick Pen Measure of Association (MTTPMA). We capture time-varying co-movement and co-movement across different time scales to analyse the short-term and long-term features of the time series using stationary data. Energy index futures show an increase in co-movement with equities since the start of the financialisation period. There are asymmetric effects in cross-scale co-movement between various commodities and equities. Weak co-movement between equity and specific commodity futures indicates diversification benefits for short-term and long-term investors. 相似文献

单家机构之间的业务趋同是否是金融业系统性风险的一个来源?近些年中国单家寿险公司的产品分布和地理分布均更加分散,但是公司之间的产品分布和地理分布均有“同质化”趋势,且公司之间在赔付风险、投资风险和破产风险上的联动性均提高。对此,本文分析了寿险公司业务同质化引起风险联动性的机理,探讨了几种可能的效应。基于公司配对样本,并从时间上和地理上引入工具变量处理业务同质度的内生性,发现:(1)当两家寿险公司的产品分布从完全差别到完全相同时,它们的投资风险联动性和破产风险联动性均将提高十几个百分点;(2)产品同质度对赔付风险联动性没有显著影响;(3)地理同质化对3种风险联动性均没有显著影响。 相似文献
