股指期货跨期套利模型研究与实证分析

我国已经推出沪深300股指期货,开始了沪深300指数合约的交易,作为股指期货三大交易类别的股指期货套利交易在股指期货交易中占有十分重要的地位,也是以各大机构投资者为主体的股指期货市场交易主体的关注热点之一.因此,研究沪深300指数股指期货套利交易策略具有很大的现实意义.本文主要对股指期货的跨期套利模型进行研究,利用模拟期货市场的数据进行实证分析,给投资者提供一些股指期货跨期套利方面的建议.     

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。     

我国股指期货套利交易策略模式初探简

股指期货市场与股市的联动效应及其风险监管

一、股指期货市场与股市的联动效应自1982年美国堪萨斯期货交易所推出价值线综合指数期货以来,股指期货成为全球发展最为迅速的金融衍生工具之一。作为典型的杠杆交易工具,股指期货在为现货市场投资者提供套期保值工具的同时,也蕴涵了巨大的金融风险。由于股指期货市场     

沪深300股指期货跨期套利基本思路

我国作为新兴市场国家,开展股指期货等金融衍生品交易,能够有效地防范系统性风险,促进资产的流通和运转,以相对较低的转轨成本促进资本市场的成熟和完善。但由于期货市场与股票市场在许多方面存在着较大差异,且期货市场合约价值较大,普通群众没有足够的经济保障可以参与其中,保证金交易又极易扩大风险,缺乏对市场规律研究的交易经常性导致亏损,影响股指期货市场的健康有序发展。通过本文对套利方法的简单介绍,有助于投资者更好地认识股指期货的作用和意义,理解套利交易的流程和基本方法,为期货投资提供基础的思路和方法。     

股指期货个人投资者权利现状研究

股指期货作为金融创新最成功的表现之一在世界范围内取得了重大的发展.但是作为新兴市场之一的中国,却一直没有开展股指期货市场.中国的金融市场已经全面开放,而且中国一系列的政策松动和立法已经表明了中国股指期货市场呼之欲出的味道.所以投资者作为股指期货市场的绝对主体,其权利保护应该受到众多投资者的高度关注.其中的个人投资者,在整个投资主体中处于相对的弱势地位,其相关权利比较容易受到侵害,本文主要关注个人投资者权利的现状.     

大陆与台湾股指期货价格发现功能比较研究

本文利用日内15分钟交易数据,对大陆与台湾股指期货的价格发现功能进行了比较,发现沪深300股指期货和现货间存在双向价格引导关系,但在信息传导效率上,期货领先现货,对台湾市场而言,仅存在期货对现货的单向引导关系;期货市场在长期价格发现功能中占主导地位,但台指期货的主导作用要强于沪深300股指期货。文章从投资者结构、合约设计、交易制度等影响因素分析了两岸股指期货价格发现功能的差异,并提出改善大陆股指期货价格发现功能的建议。

本文采用有偏项的VECM-CCC-GARCH等模型来分析投资者情绪对上证50指数期货和现货市场之间动态波动溢出效应的影响。分析发现,首先,投资者情绪高涨时期,指数现货市场交易量增加显著强于指数期货市场。其次,较高的投资者情绪对现货市场波动的影响要强于对股指期货市场波动的影响。最后,投资情绪高涨时期,期货和现货市场之间波动溢出效应显著增强,且现货向期货市场波动溢出效应显著增强。     

沪深300迷你股指期货合约设计及套期保值策略

Futures Market Sentiment and Institutional Investor Behavior in the Spot Market: The Emerging Market in Taiwan

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.     

股票市场投资者结构国际比较研究

本文梳理了A股市场与相关国家(地区)股市投资者结构的现状,探讨这些市场投资者结构的演变路径、以及促成这种演变的主要因素。基于境外主要市场投资者结构演变及政策措施的经验教训,本文提出改进A股市场相关制度的六点政策建议:第一,从更宏观的政策层面入手,改进上市公司结构,增厚上市公司利润,以增进A股市场的长期投资价值;第二,着力培育和鼓励大体量资金机构进入股市;第三,有必要继续扩大海外合格机构投资者资金规模;第四,完善金融产品供应,适当放宽交易规则约束,使机构投资者有更多工具和交易方式参与市场交易;第五,在个人投资者方面,监管部门需要适度转变监管理念,进而改进相关交易规则,鼓励个人投资者以合理方式理性参与股市;第六,创新税收激励机制,合理引导个人投资者。     

Who wins in the money game? The case of KOSPI 200 futures

This study investigates the information advantage of each investor category (i.e., foreigners, individuals, institutions, and the others) in the Korean stock index (i.e., KOSPI 200) futures market. To evaluate the information advantage of each investor category, we calculate futures trading and position gains; review and criticize the Value Weighted Average Price (VWAP) measure; and develop adjusted VWAP measures that are consistent with trading gains. Our main inferences are made based on adjusted VWAP measures. This study analyzes the transaction data of the nine years from January 1998 through 2006. From the perspectives of the adjusted VWAP measures, our findings support the information advantage of foreign investors over domestic (particularly, domestic individual) investors in the KOSPI 200 futures market.     

Investor Sentiment,Trading Behavior and Informational Efficiency in Index Futures Markets

This paper shows that traders in index futures markets are positive feedback traders—they buy when prices increase and sell when prices decline. Positive feedback trading appears to be more active in periods of high investor sentiment. This finding is consistent with the notion that feedback trading is driven by expectations of noise traders. Consistent with the noise trading hypothesis, order flow in index futures markets is less informative when investors are optimistic. Transitory volatility measured at high frequencies also appears to decline in periods of bullish sentiment, suggesting that sentiment‐driven trading increases market liquidity.     

The Effect of Investor Sentiment on Feedback Trading and Trading Frequency: Evidence from Taiwan Intraday Data

Abstract

Although extensive literature has suggested that investor sentiment may be one of the most important factors in explaining investor trading frequency and trading strategies, how individual investors are significantly influenced by sentiment remains underexplored. The feature of numerous individual investors in the Taiwan stock market provides an avenue to examine the relationship of investor sentiment to trading frequency and positive-feedback trading according to intraday data. Using a vector autoregression model to measure feedback trading in one-minute intervals, we find that trading frequency appears to increase in periods of rising market, suggesting that investor sentiment–driven trading increases market trading frequency without relying on past experiences to conduct trading behavior.     

Investor Trading Behavior and Sentiment in Futures Markets

This study investigates the effects of investor trading behavior and investor sentiment on futures market return. We find that the spot investor trading behavior, futures investor trading behavior, spot market sentiment, and futures market sentiment all have positive effects on daily futures returns in Chinese financial market. More importantly, we show that the effect of (spot) futures investor trading behavior has better explanatory power than (spot) futures market sentiment on futures returns. Further supporting our results, high investor trading behavior and high investor sentiment strengthen the positive relation between sentiment-returns and behavior-returns.     

Feedback trading in stock index futures: Evidence from South Africa

This study tests whether investors and speculators in stock index futures contracts on the South African stock market use feedback trading strategies. Feedback trading can be destabilizing and impede on the risk mitigation and price discovery functions of futures contracts. Using the Sentana and Wadhwani (1992) model, and accounting for the global financial crisis, we find no evidence of feedback trading in the Top40 futures index or the Top40 mini futures index contracts. Our findings have important implications for investors who wish to use index futures to mitigate risk or exploit arbitrage opportunities and regulators concerned about the destabilizing effects of futures trading.

On Speculation, Index Futures Markets, and the Link Between Market Volatility and Investor Welfare

This paper develops a trading model that incorporates informed speculators as well as investors who possess incorrect expectations about asset values. It is shown that the introduction of an index futures market, by stimulating additional misinformed speculation, increases market liquidity and adversely affects price variability and efficiency in the underlying stock markets. An analysis of the welfare of uninformed hedgers suggests that the relationship between uninformed investor welfare and two key parameters that dominate policy discussions, market liquidity and price variability, is quite tenuous.     

模糊厌恶下股指期货风险对冲策略设计及实证分析

投资者对股指期货与现货有着不同的模糊厌恶,本文首先将此假设条件引入带交易成本的Garleanu and Pederson (2013)投资模型中,并以指数基金对冲策略为例,构建了一个股指期货动态对冲的理论模型。与非对冲策略相比,基于上述模型设计的对冲策略投资绩效更好,动态最优成交额占目标交易额的比例更小,目标成交额对收益率预测因子的敏感性更大。借助上述模型,本文选取2010年4月至2021年6月的中国ETF指数基金和股指期货数据,并以2015年9月股指期货管理措施实施为界进行区间划分,实证研究发现:(1)中国A股市场的ETF投资组合进行股指期货对冲显著提升了投资绩效,但股指期货管理会削弱该作用;(2)投资绩效改善主要来源于交易成本的下降与目标成交额因子敏感性的提升,该机制受到股指期货管理的约束;(3)与Garleanu and Pederson (2013)、Zhang et al. (2017)相比,本文对冲策略保留“抗跌”特点的同时增加了“易涨”特性。本文研究结果表明,在当前大力发展机构投资者的背景下应不断丰富股指期货、股指期权产品谱系,降低股指期货交易成本并完善持仓约束。
