股指期货市场和现货市场间的协同波动溢出分析

采用GARCH、谱聚类方法、独立成分分析法和Granger因果检验模型相结合的方法对欧洲主权债务危机背景下的全球主要股指期货市场和现货市场间的协同波动溢出效应进行实证分析。实证结果表明股指期货市场和现货市场间具有双向协同波动溢出效应。相对而言,股指期货市场对现货市场间的协同波动溢出效应更明显,协同波动溢出程度与相应国家金融市场的发达程度有直接关系。因此有关当局进行监管时不仅做要到全球不同国家间的相互协调,与此同时还需要关注和防范风险在股指期货市场和现货市场间的相互传染。另外,我国的股指期货市场和股票市场还需进一步改革和发展。     

股指期货与股票现货市场竞争关系研究——来自中国的经验证据

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。     

沪深300股指现货和期货市场相互影响的发展趋势

从2006年的模拟股指期货交易到2009年9月中金所推出沪深300股指期货,股指期货对现货市场的影响如何？从量、波动率和分布方面来说,股指期货推出后,现货市场产生了显著变化.在现货市场和期货市场的价格发现功能方面,很多研究人员对不同时问段的样本数据进行了实证研究,本文综合其它学者的研究成果和2011年的数据的实证检验,从实证的结果发现期货市场的价格发现功能在增强.A+H等特有股本结构对结果影响不大.本文研究了年际间期货市场和现货市场相互影响的发展趋势,旨在提供一些研究参考.

股指期货市场操纵与价格发现功能的关系研究

股指期货市场操纵会影响股指期货市场的价格发现功能,同样地,股指期货市场的价格发现功能也会影响股指期货市场的操纵行为。本文在理论探讨的基础上,利用股指期货主力合约及对应的沪深300指数高频数据对市场操纵行为进行实证分析。研究结果表明,当操纵嫌疑只存在于期货市场时,股指期货市场的价格发现功能将会减弱;当操纵嫌疑存在于期货、现货两个市场时,股指期货市场的价格发现功能相对会增强。而且,当股指期货市场价格发现功能较强时,市场操纵的难度和成本都将下降。当前中国股指期货市场的操纵行为可能主要局限于某些个别的、离散的交易日内,系统地通过操纵现货指数来操纵期货市场的可能性较低。

Intraday volatility in the stock index and stock index futures markets

We examine the intraday relationship between returns and returnsvolatility in the stock index and stock index futures markets.Our results indicate a strong intermarket dependence in thevolatility of the case and futures returns. Price innovationsthat originate in either the stock or futures markets can predictthe future volatility in the other market. We show that thisrelationship persists even during periods in which the dependencein the returns themselves appears to weaken. The findings arerobust to controlling for potential market frictions such asasynchronous trading in the stock index. Our results have implicationsfor understanding the pattern of information flows between thetwo markets.     

An alternative approach to evaluating the agreement between financial markets

This research investigates that the price relationship between a stock index and its associated nearby futures markets can be explained by the cost-of-carry model using the concordance correlation (CC) coefficient in the US financial markets. The main purpose of this research is to confirm that the CC coefficient is an appropriate methodology to determine ex post arbitrage opportunities and to maximize ex ante arbitrage profits through the analysis of the price relationship derived from the cost-of-carry model. To increase the robustness of the results and to enable us to generalize our conclusions, this analysis is carried out in consideration of external uncertainty, including the marking-to-market procedure of futures contracts and the transaction cost on the stock index and its futures markets, under several assumptions related to the conditions of transactions. Examining transaction price data on the S&P 500 stock index and its futures markets shows that the CC coefficient gives a good result for ex ante arbitrage profits and is appropriate for analyzing the relationship between the observed stock index futures market price and its theoretical price derived from the cost-of-carry model.     

The Lead–Lag Relationship Between Stock Indices and Stock Index Futures Contracts: Further Australian Evidence

This article examines the lead-lag relationship in returns on stock index futures and the underlying stock index for the Australian market between 1992 and 1997. On average across the sample period, futures returns lead index returns by twenty to twenty-five minutes and there is some evidence of feedback from the equities market to the futures market. Analysis conducted on a year-by-year basis suggests that the extent to which the futures market leads the equities market has decreased over time and the relationship between the two markets has generally strengthened. This is consistent with an increase in the level of integration between the markets. The results suggest that prior research that compares lead-lag relationships across international markets and time periods in drawing inferences on the effects of market structure needs to be interpreted with caution.     

Extreme Correlation of Stock and Bond Futures Markets: International Evidence

This study explores time‐varying extreme correlation of stock–bond futures markets in three major developed countries. In the United States and the United Kingdom, there is evidence of positive extreme stock–bond correlation when both futures markets are extremely bullish or bearish. In Germany, stock–bond futures extreme correlation is negative, suggesting the most diversification potentials of bond futures when German stock index futures market plunges. Macroeconomic news, the business cycle, and the stock market uncertainty all significantly affect the median stock–bond futures correlation. However, only the stock market uncertainty still significantly affects the extreme stock–bond futures correlation when the stock market is extremely bearish.     

The Lead‐Lag Relationship Between Cash and Stock Index Futures in a New Market

This paper investigates the lead‐lag relationship in daily returns and volatilities between price movements of the FTSE/ATHEX‐20 and FTSE/ATHEX Mid‐40 stock index futures and the underlying cash indices in the relatively new futures market of Greece. Empirical results show that there is a bi‐directional relationship between cash and futures prices. However, futures lead the cash index returns, by responding more rapidly to economic events than stock prices. This speed is much higher in the more liquid FTSE/ATHEX‐20 market. Moreover, results indicate that futures volatilities spill information over to the corresponding cash market volatilities in both investigated futures markets, but volatilities in the cash markets have no effect on the volatilities of futures markets. Overall, it seems that new market information is disseminated faster in the futures market compared to the stock market. This implies that the futures markets can be used as price discovery vehicles, providing further evidence that derivatives markets contribute to completing and stabilising capital markets in Greece. A further finding of this study is that futures volume and disequilibrium effects between cash and futures prices are important variables in the explanation of volatilities in cash and futures markets.     

Modelling International Price Relationships and Interdependencies Between the Stock Index and Stock Index Futures Markets of Three EU Countries: A Multivariate Analysis

This paper addresses the important relationship between stock index and stock index futures markets in an international context. By simply examining the spot‐futures relationship within a single country as most of the extant literature does and thus ignoring possible market interdependencies between countries, the dynamics of price adjustments may be misspecified and thus findings misleading. The main contribution of the paper is to improve our understanding of the pricing relationship between spot and futures markets in the light of international market interdependencies. Using a multivariate VAR‐EGARCH methodology, the paper investigates stock index and stock index futures market interdependence, that is lead‐lag relationships and volatility interactions between the stock and futures markets of three main European countries, namely France, Germany and the UK. In addition, the paper explicitly accounts for potential asymmetries that may exist in the volatility transmission mechanism between these markets. The main conclusions of the paper imply that investors need to account for market interactions across countries to fully and correctly exploit the potential for hedging and diversification.     

Intra- and inter-regional return and volatility spillovers across emerging and developed markets: Evidence from stock indices and stock index futures

We provide empirical evidence on the patterns of intra- and inter-regional transmission of information across 10 developed and 11 emerging markets in Asia, the Americas, Europe and Africa using both stock indices and stock index futures. The main transmission channels are examined in the period from 2005 to 2014 through the analysis of return and volatility spillovers around the most recent crises based on the generalized vector autoregressive framework. Our findings demonstrate that markets are more susceptible to domestic and region-specific volatility shocks than to inter-regional contagion. A novel result reported in our study is a difference in patterns of international signals transmission between models employing indices and futures data. We conclude that futures data provide more efficient channels of information transmission because the magnitude of return and volatility spillovers across futures is larger than across indices. Our findings are relevant to practitioners, such as stock market investors, as well as policy makers and can help enhance their understanding of financial markets interconnectedness.     

Multiscale hedge ratio between the Australian stock and futures markets: Evidence from wavelet analysis

This paper examines the relationship between the Australian stock and futures markets over various time horizons. In contrast to methods employed in previous studies, wavelet analysis allows us to decompose data into various time scales. Using this technique and the Hurst exponent, we find that the Australian stock and futures markets are antipersistent. The wavelet correlation between the two markets varies over investment horizons, but remains very high. Furthermore, the magnitude of the correlation increases as the time scale increases, indicating that the stock market and the futures market of the All Ordinaries Index are found to be not fundamentally different. The hedge ratio increases as the wavelet time scale increases. In addition, the effectiveness of hedging strategies initially increases with the hedging horizon.     

An extensive analysis on the Japanese markets via S. Taylor's model

Applying S. Taylor's approach (1986), we make an extensive analysis on the Japanese stock market, foreign exchange market and the Japanese Government Bond Futures market. The purpose of this paper is to empirically reveal the structure of the Japanese markets via Taylor's model rather than to propose a new model. For this reason, we include a variety of analyzed data particularly for the Japanese stock market and the foreign exchange market because the results can be used in a different manner. The paper consists of three parts. But each part can be read separately. Part 1: Overshooting hypothesis for Japanese stock prices Part 2: A trend movement in daily/weekly Yen-Dollar exchange rates Part 3: Price variations of Japanese Government Futures. In the first part, the stock prices are shown to over-respond to new information, which is different from the behaviors of stock prices in other markets. In Part 2, a trend movement is revealed in Yen-Dollar exchange rates. In Part 3, a strategy in the Japanese Government Bond futures markets is shown to perform better than a buy and hold strategy.
