我国黄金期货市场价格波动研究 总被引:1,自引:0,他引:1
以上海期货交易所2008年1月9日至2011年6月30日的黄金期货市场量价关系为研究对象,构建了GARCH(异方差)族模型检验我国黄金期货市场的价格波动特征.研究结果表明,当分别引入黄金期货市场的交易量和持仓量时,交易量对价格波动的影响在当期和滞后期均十分显著,而持仓量对价格波动的影响在当期显著,滞后期则不显著;当同时引入黄金期货市场交易量和持仓量时,他们对价格波动的解释作用增加,且当期统计检验显著,滞后期效应则不明显. 相似文献

We examine the role of gold as a hedge and safe haven from the perspective of Chinese investors. Using the Shanghai Futures Exchange (SHFE)-Gold futures prices and the CSI 300 index from 2008 to 2017, we find that gold is not a hedge against the Chinese stock market on average. However, gold acts as a safe haven when market returns are below their 1%, 5%, and 10% quantiles and during the two crash periods. Our findings apply to most of the industry sectors as well. We also show that the role of gold can change drastically due to some market policy reforms. 相似文献

From September 1919, the world price of gold was ‘fixed’ daily in London by a small group of licensed traders. The arrangement was not ideal, as it advantaged the traders concerned, but it was seen by the Bank of England at the time as critical to British economy recovery and to the maintenance of London’s position as a world trading centre. This article examines the available archival evidence on whether direct knowledge of the workings of the mechanism enabled Mocatta and Goldsmid, traders central to the operations of the ‘gold fix’, to earn unusually high profits across the interwar period. 相似文献

中国目前静态的期货保证金水平只是一个经验数字,对价格波动并不敏感,大部分时间投资者资金被过度占用,当市场波动剧烈时又不能覆盖足够的风险。本文研究了基于非正态分布下黄金期货保证金水平,利用广义极值分布和广义帕累托分布来拟合尾部风险。结果显示:黄金期货存在尖峰厚尾现象,在考虑流动性风险后,现有的保证金水平有下调空间,应设定为4.38%,当风险加大时应提高到5.15%。 相似文献

China is a leading participant in the world cotton market. China’s distinctive regulatory structure and procedures and business environment provide an opportunity to explore some unique market dynamics. This study investigates the interrelationship among the spot, futures, and forward cotton markets in China over a period of a major policy change: A temporary State reserve program for cotton that was established in 2011 and ended in 2014. This government intervention significantly distorted the way farmers, manufacturers, and speculators interacted and was not sustainable. Overall, our results support futures market’s dominant role in the price discovery process. 相似文献

We develop a model for the VXX, the most actively traded VIX futures exchange-traded note, using Duffie, Pan, and Singleton's affine jump diffusion framework, where the volatility process has jumps and a stochastic long-term mean. We calibrate the model parameters using the VIX term structure data and show that our model provides the theoretical link between the VIX, VIX futures, and the VXX. Our model can be used for pricing VIX futures, the VXX and other short-term VIX futures exchange-traded products (ETPs). Our model could be extended to price options on the VXX and other short-term VIX futures ETPs. 相似文献

发展我国期货投资基金研究 总被引:1,自引:0,他引:1
国际期货市场发展的历程表明,以机构投资者为主体的投资者结构是期货市场走向成熟的一个重要标志。而期货投资基金正是机构投资者中非常重要的一种组织形式。发展期货投资基金不但有利于解决我国期货市场规模小、流动性差的问题,同时对我国资本市场的持续、健康、稳定发展也将起到巨大的推动作用。发展期货投资基金已经成为整个期货业和资本市场梦寐以求的目标。 相似文献

Shariah money is gold and silver, supplied by the market on profit criterion. Everywhere, government inconvertible paper money arose from bankruptcy. A government with balanced budgets would never need it. Imposed by force, inconvertible paper is a taxation mean, highly inflationary, and causes impoverishment. Unjust and bankrupt governments will continue to force this despotic money. Islamic Monetary Economics refutes the idea of money as a policy tool. Fully convertible paper is Shariah compliant. Shariah requires a just government to balance its budgets and restore fully gold and silver as lawful money. 相似文献

石油期货:完善我国石油安全机制的必然选择 总被引:2,自引:0,他引:2
国际油价波动通过石油进口对国内经济产生影响,成为我国石油供应安全的隐患。国际油价的形成机制是现货市场与期货市场共同影响市场价格走向,由于没有形成国际化的石油市场体系,转嫁风险机制缺位,我国在国际石油市场采购现货时不得不量价齐升。发展石油期货市场,完善国内石油市场体系,是建立和完善我国石油安全机制的必然选择。 相似文献

The Samuelson hypothesis asserts that futures volatility increases as maturity decreases. On the basis of 10 US commodity futures and by capturing the dynamics of the futures volatility terms structure with three factors, we show that in most markets the slope factor is strongly negative in certain periods and at best only weakly negative in other periods. High inventory levels are found to correspond to flatter volatility term structures in seven futures. This finding is consistent with the linkage between carry arbitrage and the Samuelson hypothesis. We also find that a flatter volatility term structure corresponds to lower absolute futures term premiums. 相似文献
