基于基差和价格预测的套期保值思路初探

现有的套期保值主要集中在套期保值比率的研究,主要的方法有基于回归技术的确定方法以及基于均值/方差技术的确定方法.本文尝试将金融价格预测方法融合到套期保值中,建立了一个基于基差和价格预测的对套保比率缩放的思路,而具体的缩放阈值及比率则根据个人的风险偏好来确定.     

引入基差影响因素的套期保值模型优化与效用对比分析——以中国大豆加工与经营企业为例

中国是全球最大的大豆进口国,国内大豆压榨企业在用境外定价中心的期货合约进行套期保值时,面临较大的基差风险。现有套期保值模型中,多将基差作为套期保值模型的不可观测变量,这与大豆压榨企业现实需求不符。为此,将基差影响因素中可解释部分引进套期保值模型,得到基差调整后的套期保值比率和套期保值有效性。运用Copula-GARCH模型实证分析后发现,引入基差影响因素的套期保值模型效果大多数优于原有套期保值模型,这对我国压榨企业的套期保值实践具有重要的指导意义。

运用股指期货有效规避系统性风险之方法研究

股指期货可以有效地规避系统性风险，其基本原理是股份指数组合与股指期货合约的变动率呈正相关，只要在现货市场和期货市场进行相反的操作，就可以控制风险水平，股指数货规避系统性风险的方法包括套期保值，套利，利用股指期货规避系统性风险的实质是风险转移。我国股市的系统性风险比较大，开设股指期货显得日益重要。     

浅论套期保值在规避外汇汇率风险中的运用

市场经济中,汇率时刻都处在剧烈的上下起浮变动之中,因汇率波动而造成的外汇风险已成为经济主体无法回避的问题。如何利用套期保值最大限度的防范外汇风险,减少汇率波动带来的风险损失,是本文讨论的重点。本文将针对什么是外汇汇率风险、套期保值规避汇率风险的原理以及如何进行套期保值操作进行简要阐述,以说明如何利用套期保值来有效规避汇率风险。     

期货市场规避不确定性的微观经济学研究

对于厂商而言,不确定性就是生产中不可缺少的因素,也是对厂商的利润有着直接影响。对于期货市场而言,刚好为厂商提供了不确定性的规避功能,厂商可以在期货市场上进行买卖,将现货市场上出现的不确定性风险进行消除。本文将通过微观经济学进行分析,并对期货市场的套期保值进行介绍,显示出在期货市场中对于不确定性的风险规避作用。     

我国股指期货套期保值交易策略研究

Is hedging successful at reducing financial risk exposure?

This article analyses whether firms use risk management instruments for hedging or speculative purposes. First, by analysing the relationship between the firm’s stock returns and financial risks in 567 Euronext firms, we measure the firm’s exposure to risk. Next, we investigate the effect of hedging in such exposures, addressing simultaneously the endogeneity of hedging decision through a treatment effect methodology. We have found that firms in our sample display higher percentages of exposure, when weighed against preceding studies, and confirmed that hedging reduces the level of the underlying financial exposure, concluding that firms use risk management instruments with hedging purposes.     

全面风险管理:必然的选择

始于运用VaR方法度量金融市场风险的金融风险管理革命,目前已扩展至对企业的全面风险管理。一个理想的全面风险管理体系应站在企业全局的角度去识别、度量和管理风险。全面风险管理体系的优势在于:它有助于通过对冲风险以达到降低收益波动性的目的,从而增加企业价值;它有助于降低对冲的成本,因为它实际上是对净风险的对冲,而不是在单独的风险管理方法下的逐个对冲,这就使得风险的对冲成本下降了。     

Interest rate risk estimation: a new duration-based approach

Duration is widely used by fixed income managers to proxy the interest rate risk of their assets and liabilities. However, it is well known that the convexity of the price-yield relationship introduces approximation errors that grow with changes in yield. In this article we suggest a new approach, ‘discrete duration’, which significantly improves upon the accuracy of traditional duration methods and achieves a level of accuracy close to the more complex ‘duration-plus-convexity’ measure. In particular, discrete duration performs particularly well for long dated and low coupon rate bonds where the estimation error is impressively close to zero.     

风险与监管双重影响下的商业银行行为选择

本文运用微观银行理论的产业组织方法，构建了一个含有信用风险和准备金监管要求的风险中性商业银行行为模型。在引入资本监管要求后，借助风险价值（MaR）概念，分析了影响银行行为的因素。结果发现，法定准备金不影响银行的风险行为，但资本监管要求导致风险中性的银行表现出风险厌恶。商业银行有内在的激励去从事风险对冲，并可以从中获益。最后，结合我国的实际情况，提出了银行改革和金融市场建设的相关建议。     

Intraday hedging with financial options: the case of electricity

As market intermediaries, electricity suppliers purchase electricity from the wholesale market or self-generate to deliver their customers. However, electricity suppliers are uncertain about how much electricity their residential customers will use at any hour of the day until they actually turn switches on. While demand uncertainty is a common feature of all commodity markets, suppliers generally rely on storage to manage it. Singularly, electricity suppliers are exposed to joint volumetric and price risk on an hourly basis given the physical attributes of electricity. In the literature on electricity markets, few articles compare the efficiency of forward contracts, options and physical assets (i.e. power plants) within intraday hourly hedging portfolios, whereas electricity markets are precisely hourly markets. We analyse portfolios made of forwards, options and/or power plants for specific hourly clusters (9 am, 12 pm, 18 pm, 9 pm) based on electricity market data from 2013 to 2015 from the integrated German–Austrian spot market. Through a VaR model, we prove that intraday hedging with forwards is structurally inefficient compared to financial options and physical assets, no matter the cluster hour. Moreover, our results demonstrate the contribution of ‘out of the money’ options for all hours within volatile spot markets.     

Hedging the portfolio of raw materials and the commodity under the mark-to-market risk

This paper considers the hedging problem of a portfolio composed of raw materials and a commodity. A new theoretical model is presented to manage the risk exposure of the portfolio under the mark-to-market risk. Moreover, we employ the Lemke algorithm to obtain the optimal hedging strategy. We use a case of the soybean oil manufacturer from May 2008 to June 2011 to illustrate the proposed model and algorithm. The results show that the mark-to-market risk must be taken into account when devising the hedging strategies.     

The effect of family ownership on corporate hedging: the case of Thailand

We explore how corporate hedging decisions are affected by family ownership and control in Thailand. One crucial advantage of investigating this issue in Thailand is that hedging instruments became available only recently, long after families established their presence in the firm. Thus, endogeneity is much less likely. The evidence shows that family ownership by itself does not have a significant impact on the firm’s propensity to hedge. However, when family members have a presence on the board of directors, the firm is significantly more likely to engage in hedging activities. Furthermore, we find that the presence of institutional blockholders also increases the likelihood of hedging significantly. Our study is the first to examine the impact of family ownership and control on corporate hedging behaviour in an emerging market.
