We investigate the integration of oil spot and futures markets using matched, intraday data to avoid nonsynchronous trading issues. Our evidence indicates highly integrated spot and futures markets. Economic shocks that arise in spot markets are quickly transmitted to the futures markets approximately one-for-one. Most of the reaction occurs within minutes. Similarly, economic shocks arriving in futures markets are transmitted to spot markets one-for-one, once again, within minutes consistent with market efficiency. In general, our findings indicate well-functioning, well-integrated spot and futures oil markets that are informationally efficient and that perform the functions of both price discovery and risk transfer. To the best of our knowledge, this is the first article to work with precisely matched customized data in futures markets, specifically oil futures markets. 相似文献

This paper examines the volatility transmission mechanism between the futures and corresponding underlying asset spot markets, focusing on Turkish currency and stock index futures traded on the lately established Turkish Derivatives Exchange (TURKDEX). Employing multivariate generalized autoregressive conditional heteroskedasticity modeling, which allows for potential spillovers and asymmetries in the variance-covariance structure for the market returns, the paper investigates the volatility interactions among each of the three futures-spot market systems. For all market systems under study, the volatility spillovers are found to be important and bidirectional. For the stock index market system, in line with the previous literature, volatility shows asymmetric behavior and strong asymmetric shock transmission. The main implication is that investors need to account for volatility spillovers and asymmetries among the futures and the spot markets to correctly build hedging strategies. 相似文献

This article investigates the dynamic pattern of stock market relations between the ASEAN Economic Community (AEC) and two major stock markets: China and the United States. A GARCH risk decomposition model is developed to reflect the time-varying market integration. The primary findings of this study are as follows. First, the AEC is more integrated with the regional stock market than with the global stock market. Second, the movement in the AEC stock market is mainly driven by domestic economic situations. Third, external shocks only affect the level of integration of the AEC temporarily. Finally, international investors are able to significantly reduce unsystematic risk by adding an AEC market portfolio into their existing portfolios. 相似文献

In this paper we explore some recent trends in the financial market and also report some studies of the Singapore futures markets. A characterization of trends shows that national securities markets are much closer than before. This means the linkages between securities and their derivatives and amongst themselves have be come much stronger. Secondly, the advent of sophisticated risk products and instruments and the knowledge to use them effectively would become a common theme together with the idea of value enhancements. Thirdly, computerizations and the internet will play an increasingly important role. So will empirical financial research become increasingly microscopic. The discussion will be supported by the experiences of the Singapore futures markets and various empirical research evidences. The paper also provides a detailed study of causality-in-variance test of information transmission between SIMEX and Osaka Stock Exchange on the Nikkei 225 stock index futures trading prior to, during, and immediately after the announcement of the collapse of Barings. The results are indicative of very strong international market linkages and a portent of things to come. 相似文献

This study examines the pricing efficiency for the leading cryptocurrency, Bitcoin using spot prices and all CBOE and CME futures contracts traded from January 2018 to March 2019. We find that the futures basis provide some predictive power for future changes in the spot price and in the risk premium. However, the basis of Bitcoin is a biased predictor of the future spot price changes. Cointegration tests also demonstrate that futures prices are biased predictors of spot prices. Deviations from no-arbitrage between spot and futures markets are persistent and widen significantly with Bitcoin thefts (hacks, frauds) as well as alternative cryptocurrency issuances. 相似文献

This article provides a new perspective on the efficiency of futures markets in a cointegration framework. Under the conventional risk premium hypothesis, if futures and spot prices are non-stationary, they must be cointegrated if futures markets are efficient. Alternatively, the cost-of-carry model implies that there should be a cointegration relationship among spot prices, futures prices and interest rates assuming all the series contain a unit root. Market efficiency further implies specific parameter restrictions under these two models. Using data on the futures markets for gold, silver, palladium and platinum, this article first establishes that interest rates, spot and futures prices are unit root non-stationary. The evidence on cointegration is somewhat mixed: the gold futures market is consistent with the cost-of-carry model, and the silver futures market satisfies the risk premium hypothesis, but the evidence for the other two markets is inconclusive. 相似文献

This paper investigates whether and how futures market sentiment and stock market returns heterogeneously affect the trading activities of institutional investors in the spot market in Taiwan. Our empirical results suggest that foreign investors are net sellers whenever futures market sentiment is bullish and net buyers when investor sentiment is bearish. The two types of domestic institutional investors have poor sentiment timing abilities and the price-pressure effect may account for the behavioral differences among institutional investors. In addition, all three institutional investors are momentum traders. Nevertheless, the momentum trading of foreigners is consistent with an information-based model and that of two local institutional investors, as behavior-based models suggest. This indicates that the same trading momentum strategy can lead to different outcomes for different investors, and both information- and behavior-based momentum trading can exist contemporaneously in the Taiwanese stock market. 相似文献

This study examines the cross‐sectional variation of futures returns from different asset classes. The monthly returns are positively correlated with downside risk and negatively correlated with coskewness. The asymmetric volatility effect generates negatively skewed returns. Assets with high coskewness and low downside betas provide hedges against market downside risk and offer low returns. The high returns offered by assets with low coskewness and high downside betas are a risk premium for bearing downside risk. The asset pricing model that incorporates downside risk partially explains the futures returns. The results indicate a unified risk perspective to jointly price different asset classes. 相似文献

本文利用模拟生态学中种群间动态关系的Lotka-Volterra模型,对沪深300股指期货同股票现货市场在交易规模方面的竞争关系进行实证分析。研究结果表明,沪深300股指期货推出初期,股指期货市场与股票现货市场在交易规模方面存在竞争性的交易转移效应;随着股指期货市场相关规则的不断健全和完善,股指期货市场与股票现货市场在交易规模方面由竞争关系转变为共存关系,出现交易引资效应。同时,研究还发现,股指期货市场与股票现货市场之间关系由竞争性转变为共存性的重要原因是股指期货市场监管力度的加大,股指期货市场投资者结构的优化,以及股指期货市场期现套利交易的盛行。 相似文献

This study examines the relationships among stock prices in eighteen national stock markets by using unit root and cointegration tests for the period 1961--92. All the markets were analyzed individually and collectively in regions to test for market efficiency. The results from unit root tests suggest that the world equity markets are weak-form efficient. The cointegration test results show that there are only a small number of significant cointegrating vectors over the last three decades. However, the number of significant cointegrating vectors increases after the October 1987 stock market crash, a result that is consistent with the contagion effect. 相似文献

中国期货市场套期保值绩效实证研究 总被引:3,自引:0,他引:3
为了研究中国期货市场的套期保值绩效,本文利用确定套期保值比率的OLS、B-VAR、ECHM和EC—GARCH四个模型和套期保值绩效的衡量指标,对中国期货的小麦、大豆、铜和铝的套期保值比率和绩效进行了实证研究,使用1998~2004年中国期货与现货价格的周数据来进行单位根和协整检验等计量分析。研究显示,金属期货品种的套期保值比率和绩效比农产品期货品种的套期保值比率和绩效都要高。考虑了协整关系的ECHM和EC—GARCH模型的套期保值比率和绩效比没有考虑协整关系的OLS和B—VAR模型高,样本区间外的套期保值绩效优于样本区间内的绩效。本文认为采用ECMH和EC—GARCH模型进行套朔保值是最佳的策略。 相似文献

本文采用信息份额模型和基于向量自回归(VAR)模型的格兰杰因果检验,研究了国债现货、国债期货和利率互换三个市场之间的价格发现机制。信息份额模型表明,从整体来看利率互换相对于国债期货和国债现货都具有信息优势,而国债期货相对于国债现货具有信息优势。另外,国债期货的价格发现能力相对于另外两个市场都在随时间增强。格兰杰因果检验结果显示,利率互换在价格发现中单向引领国债期货以及国债现货,国债期货单向引领国债现货。所有结果一致表明, 利率互换和国债期货这两种利率衍生产品在引导中国利率市场价格发现中发挥了重要作用。 相似文献

从制度设计上打破市场分割、促进市场整合,对提高市场效率、促进经济有序健康发展具有重要意义。本文以商品期货上市作为准自然实验,构建双重差分模型,实证检验了商品期货上市交易对现货商品市场价格整合的影响。研究发现,现货商品市场价格整合程度在相应商品期货上市后显著提升,这是因为商品期货上市显著地促进了价格信息在全国范围内的传导,且这种提升效应主要体现在价格信息传导比较顺畅的地区。此外,商品期货上市提高了现货商品市场价格同步性,缓解了现货商品价格信息滞后程度,降低了现货商品交易成本。进一步研究发现,商品期货市场的交易信息质量越高,越有利于提高现货商品市场的整合程度。本研究为当前我国建设全国统一大市场提供了一定参考。 相似文献

A wide array of official capital controls across countries makesit difficult to perform cross-sectional analysis of the effectsof market segmentation. This article constructs a measure ofdeviations from capital market integration that can be consistentlyapplied across countries. It measures the deviations of assetreturns from an equilibrium model of returns constructed assumingmarket integration. Applying the measure to stock returns fromtwenty-four national markets indicates that market segmentationtends to be much larger for emerging markets than for developedmarkets, and that the measure tends to decrease over time. Alongseveral dimensions, the proposed measure yields results thatare consistent with reasonable priors about the relations betweeneffective integration and explicit capital controls, capitalmarket development, and economic growth. 相似文献

This paper focuses on the role of scalpers as marketmakers in the competitive auction of futures exchanges. We use transactions data of a representative scalper to identify the source of scalper earnings. We find that scalpers provide liquidity services to incoming market orders, thereby facilitating commercial hedging. Scalper earnings are positively related to the bid-asked spread and negatively related to the length of time a position is held. 相似文献

This article investigates the empirical link between international consumption risk sharing, financial integration, and financial development for a group of twenty-nine developed and developing countries in the G7, the Euro area, and the OECD. Estimation results indicate that (1) risk sharing in the Euro area is higher than those in the G-7 and the OECD, and (2) a higher degree of risk sharing is associated with a greater degree of financial integration and a lower level of financial development. These results suggest that more financially integrated countries might be better able to insure themselves against idiosyncratic income shocks and countries with more developed financial markets might tend to engage in less consumption risk sharing with other countries thanks to their own sophisticated financial markets. Holding financial integration and financial development equal, countries in the Euro area engage in significantly more risk sharing than the ones in the G7 and the OECD. 相似文献
