案例续
长期资本管理公司以“不同市场证券间不合理价差生灭自 然性”为基础,制定了“通过电脑精密计算,发现不正常 市场价格差,资金杠杆放大,入市图利”的投资策略。 舒尔茨和默顿将金融市场历史交易资料,已有的市场理论、 学术研究报告和市场信息有机结合在一起,形成了一套较 完整的电脑数学自动投资模型。他们利用计算机处理大量 历史数据,通过连续而精密的计算得到两种不同金融工具 间的正常历史价格差,然后结合市场信息分析它们之间的 最新价格差。如果两者出现偏差,并且该偏差正在放大, 电脑立即建立起庞大的债券和衍生工具组合,大举套利入 市投资;经过市场一段时间调节,放大的偏差会自动恢复 到正常轨迹上,此时电脑指令平仓离场,获取偏差的差值。

提供风险管理的工具与技术 投机和套利机会的发掘 公司重组安排与财务配置 避税策略和税务筹划
一、提供风险管理的工具与技术
风险管理在金融工程中居于核心地位。 风险即不确定性 1、用不确定性来代替风险; 2、替换掉与己不利的风险,保留有利风险。 3、分散风险 案例:最初出现于20世纪70年代初的美国住房 抵押贷款市场资产证券化方案的实施
案例:ESL 投资基金收购K-Mart
K-Mart经营不善债务累累﹐二十亿美金的债务 无法偿还﹐导致这个百 年老店被迫进入破产保 护。2003年5月5日是K-Mart可以走出破产法庭 最后期限﹐就在此生死存亡关头﹐当时名不见 经传的康州40岁投资人爱得华兰博(Edward Lampert) 的ESL 投资基金 公司成功地将二十 亿美金的债务折价买下(具体金额是保密的﹐ 业内灵通人士估计在二亿五至五亿之间)﹐然 后投资三亿五定向增发给ESL﹐使得他成为走 出破产后K-Mart公司的69%大股东。

➢ 套利机会存在的条件: ➢ (1)如果存在两个资产组合,它们的未来收益(现金流)
相同,但它们的成本(价格)不同,这时市场存在套利机 会。 ➢ (2)如果存在两个相同成本(价格)的组合,第一个组合 在所有状态下的收益都不低于第二个组合,而且至少存在 一种状态,在此状态下第一个组合的收益大于第二个组合 ,这时市场存在套利机会。 ➢ (3)如果一个组合的构建成本为0,但在所有状态下这个 组合的收益都不小于0,而且至少存在一种状态,在此状态 下这个组合的收益大于0,则市场存在套利机会。

金融远期合约(Forward Contracts)是指双方约定在未 来的某一确定时间,按确定的价格买卖一定数量的某种金 融资产的合约。在合约中,未来将买入标的物的一方称为 多方(Long Position),而在未来将卖出标的物的一方称 为空方(Short Position)。

❖ 特定期货合约的合约规模、交割日期和交割地点等都 是标准化的,在合约上均有明确规定,无须双方再商 定,价格是期货合约的唯一变量。
❖ 一般来说,常见的标准期货合约条款包括: (1)交易单位。交易所对每个期货产品都规定了统 一的数量和数量单位,统称“交易单位”(Trade Unit)或“合约规模”(Contract Size)。不同交 易所、不同期货品种的交易单位规定各不相同。
17
与远期合约的分类相似,根据标的资产不同, 常见的金融期货主要可分为股票指数期货、外汇期 货和利率期货等。 -股票指数期货是指以特定股票指数为标的资产的期 货合约,S&P500股指期货合约就是典型代表。 -外汇期货则以货币作为标的资产,如美元、德国马 克、法国法郎、英镑、日元、澳元和加元等。 -利率期货是指标的资产价格依赖于利率水平的期货 合约,如欧洲美元期货和长期国债期货等。

3.远期股票合约 远期股票合约(Equity Forwards)是指在将来某一特 定日期按特定价格交付一定数量单只股票或一揽子 股票的协议。远期股票合约在世界上出现时间不长, 总交易规模也不大。

缅甸玉石的启示:新信息
在缅甸开采玉石矿的市场上,摆放着各种未 经过任何雕琢的矿石。这些矿石中有可能包 含有大量的翡翠,也可能只有很少一点翡翠。 买卖双方其实都不知道这些矿石中究竟含有 玉多 以 现石便 玉少?请使 石翡得大之 有翠到家露可。新讨出能买信论更含主息:多有可你之有高以是后关成选否,成色择有对色的打必你的翡磨要有信 翠和去好息 ,擦打处, 那拭磨吗一 么玉一?旦 卖石块发 方, 就会相应提高价格,反之降价。从这个例子 中,我们可以得出两点重要的发现:(1) 信 息越多的地方,不确定性就越少,越容易形 成双方都接受的稳定价格。(2) 市场价格的 变动是由新出现的信息推动的,因为新信息 改变了人们对某资产未来价值的预期。

2.1.2 主要金融远期合约种类
• 根据标的资产不同,常见的金融远期合约 包括 1.远期利率协议 2.远期外汇协议 3.远期股票合约
2.1.2 主要金融远期合约种类
• 1.远期利率协议
远期利率协议是买卖双方同意从未来某一商定 的时期开始在某一特定时期内按协议利率借贷一 笔数额确定、以具体货币表示的名义本金的协议。 之所以称为“名义”,是因为借贷双方不必交换 本金,只是在结算日根据协议利率和参考利率之 间的差额以及名义本金额,由交易一方付给另一 方结算金。
• 远期合约并不能保证其投资者未来一定盈 利,但投资者可以通过远期合约获得确定 的未来买卖价格,从而消除了价格风险。
2.1.1 金远期合约的定义

(a) 远期多头的 到期盈亏
(b) 远期空头的 到期盈亏
如果到期标的资产的市场价格高于交割价格K,远期多头就 盈利而空头就会亏损;反之,远期多头就亏损而空头就会盈 利。
远期利率是指现在时刻的将来一定期限的利率。 如14远期利率,即表示1个月之后开始的期限3 个月的远期利率。
2.1.2 主要金融远期合约种类
• 2.远期外汇合约
远期外汇合约是指双方约定在将来某一时间按 约定的远期汇率买卖一定金额的某种外汇的合约。
按照远期的开始时期划分,远期外汇合约又分 为直接远期外汇合约和远期外汇综合协议。
第二章 远期与期货概述
2.1.1 金融远期合约的定义
• 金融远期合约(Forward Contracts)是指 双方约定在未来的某一确定时间,按确定 的价格买卖一定数量的某种金融资产的合 约。在合约中,未来将买入标的物的一方称 为多方(Long Position),而在未来将卖 出标的物的一方称为空方(Short Position)。

分析方法
一、投资组合理论的起源
1952年,美国经济学家哈里·马柯维茨发表的 《投资组合选择》(Portfolio Selection)的论文标 志着现代投资组合理论的开端。
投资者在寻求预期收益最大化的同时,也在寻求收 益不确定性的最小化。在此基础上,马柯维茨建立了著 名的“均值—方差模型”来分析投资者的资产选择行为。 这一模型后来成为现代投资组合理论的核心与基石。
APT模型是CAPM模型的一个推广。但与 CAPM模型不同的是,该模型表明资产的期望收益 率受一组公共风险因子影响,市场组合可能只是其 中的一个风险因子,其他风险因子(诸如利率、通 货膨胀率、GDP增长率等)也可能包括在内。简单 地说,市场组合在套利定价理论中并没有特殊作用, 它只是可能影响资产收益的因素之一。
二、多因素套利定价模型
设市场上风险资产的收益一共受到k个风险因 素的影响,可表示如下:
k
ri Eri ij Fj ei j 1
其中,ri是任意一种风险资产的收益,E(ri)是该风险 资产的预期收益,Fj(j=1,2,…,k)是影响风险资产收 益的公共风险因子,βij (j=1,2,…,k)是第i个风险资 产的收益与第j个影响因素之间的协方差,表示风险资产对 不同公共风险因子的敏感度,ei是残差项。

(金融工程)Chapter 2 The structure of options market

(金融工程)Chapter 2  The structure of options market

Advantages of the OTC options market
• Terms and conditions can be tailored to the specific needs of two parties
• It is a private market, no others can know the transaction
Exercise price
• The exchange prescribes the exercise prices.
• FLEX option can have any exercise price • The exchange elected not to adjust the
exercise price when a cash dividend was paid.
The difference between offsetting in the OTC market and offsetting in the exchange market is that in the latter the contracts cancel any obligation of the writer. In the former, both contracts remain on the books, so they are both subject to default risk.
The order book official
• Obo is also called board broker, an employee of the exchange.
The mechanics of trading
• Placing an opening order • The role of the clearinghouse • Placing an offsetting order • Exercising an option

金融工程应用教程-答案

金融工程应用教程-答案

金融工程习题解答第二章 远期合约1、如何区分远期价值和远期价格的不同含义。

答:远期合约的价值是合同的价值,用f 表示;远期价格F 是标的资产的理论价格,是远期合约价值f 为0时的交割价。

2、FRA 协议中的几个日期之间有何关系?答:FRA 协议中的几个日期之间的关系如下图所示:其中的确定日、结算日、到期日,遇到节假日及法定休息日向前延伸或向后顺延。

3、请解释远期合约用来套期保值和来投机的方法。

答:套期保值,是签订远期合约,将未来交易的利率或汇率固定下来,避免利率或汇率波动对于负债或收益带来的风险。

投机,是建立在某种预期的基础上,以承担风险为代价获取收益的远期交易。

当投资者预期标的资产将上涨时做多头,反之做空头。

4、解释为什么外币可以被视为支付已知红利率的资产?答:由于外币的隶属国对于存入银行的外币按一定的利率支付利息,故外币可看成支付红利的资产。

5、当一种不支付红利股票的价格为$40时,签订一份1年期的基于该股票的远期合约,无风险利率为10%(连续复利),试问:(1) 远期价格为多少?远期合约的初始价值为多少?(2) 两个月后,股票的价格为$45,远期价格和远期合约价值各为多少?解:已知:S=40,T -t =1,r =10%。

交易日 起算日确定日 结算日 到期日(1) 根据公式(2-2-2)有:F=Se r (T-t )=40e 0.1×1=44.21(美元),初始价值:f =0。

(2) 已知:S=45,T -t =10/12,r =10%。

根据公式(2-2-2)有:F=Se r (T-t )=45e 0.1×5/6=48.91(美元)根据公式(2-2-1)有:f =45-40=5(美元)。

7、已知美元的即期利率为5%,人民币的即期利率为2%。

当前的人民币对美元的汇率是6.80:1,我国人民币计息天数为365天,问:一年之后的人民币对美元的远期汇率是多少?解:已知:S =6.80,r =0.05,r f =0.02,由公式(2-4-1)有:8、远期利率协议某交易日是2010年5月12日星期三,双方同意成交1×4金额100万美元,利率为6.25%的远期利率协议,确定日市场利率为7%。

金融期货合约(Financial Futures Contracts) 是指在交易所交易的、协议双方约定在将来某个 日期按事先确定的条件(包括交割价格、交割地 点和交割方式等)买入或卖出一定标准数量的特 定金融工具的标准化协议。同样,我们称在合约 中未来将买入标的物的一方为多方,而在未来卖 出标的物的一方为空方。合约中规定的价格就是 期货价格。
11
远期合约是适应规避现货交易风险的需要而产 生的。
远期市场的交易机制可以归纳为两大特征:分 散的场外交易和非标准化合约。
远期合约不在交易所交易,而是在金融机构之 间或金融机构与客户之间通过谈判后签署的。其交 易主要是私下进行的,基本不受监管当局监管。

❖ 在盯市结算完成以后,如果交易者保证金账 户的余额超过初始保证金水平,交易者可随 时提取现金或用于开新仓。但交易者取出的 资金额不得使保证金账户中的余额低于初始 保证金水平。
33
❖ 而当保证金账户的余额低于交易所规定的维持保证金 (Maintenance Margin)水平时(维持保证金水平通
❖通常期货合约的到期交割可能有两种方式:现 金交割与实物交割。

29
❖ 除了以上5个方面之外,期货合约中通常还有诸如交 易时间、产品代码、头寸限额(Position Limit)等不 太重要的或是不具有一般性的标准条款。
注意:远期交易是到期一次性结算的,所以在远 期存续期内,实际交割价格始终不变,标的资产市场价 格的变化给投资者带来的是账面浮动盈亏,到期结算时 标的资产的市场价格与交割价格的差异才是投资者的真 实盈亏。
期货则有所不同。由于期货是每日盯市结算实现 真实盈亏的,因此可以把期货看作一个每日以结算价平 仓结清并以该结算价重新开立的合约,每日结算价格就 是不断变动的期货交割价格。
20
金融期货问世至今不过短短三十余年的历
史,但其发展速度却相当惊人。时至今日,金融
期货交易在许多方面都已经远远走在了商品期货
交易的前端。一些重要的期货交易甚至可以一天
24小时在世界各地不同的期货市场上连续进行。
目前全球最大的期货交易所当属2007年7月

与远期合约的分类相似,根据标的资产不同, 常见的金融期货主要可分为股票指数期货、外汇期 货和利率期货等。 -股票指数期货是指以特定股票指数为标的资产的期 货合约,S&P500股指期货合约就是典型代表。 -外汇期货则以货币作为标的资产,如美元、德国马 克、法国法郎、英镑、日元、澳元和加元等。 -利率期货是指标的资产价格依赖于利率水平的期货 合约,如欧洲美元期货和长期国债期货等。
❖ 这些标准化的期货合约条款看似对期货交易进行了高 度的限制,但实际上正是由于期货合约的高度标准化, 价格成为期货合约交易中的唯一变量,才使得期货头 寸的开立和平仓能够非常便利地进行,大大提高了期 货合约的交易效率和流动性,促进了期货交易的发展, 使其成为期货有别于远期的一个重要特征。

❖ 在这些公司签订的远期股票合约中,约定的远期 价格通常高于签订时的股票市价。例如2000年3月礼 来公司签订远期股票合约,约定在2003年年底以前购 买本公司450万股股票时,该公司的股票市价为70美 元左右。而远期股票合约中的协议价格定在86美元到 100美元。然而到了2002年9月,礼来公司的股票市价 却跌至55美元上下,致使礼来公司面临着1.5亿美元 的潜在亏损。类似的,由于被迫购买其544万股股票, 电子资讯系统公司在2002年的短短几个月内便损失了 约1亿美元。

3.远期股票合约 远期股票合约(Equity Forwards)是指在将来某一特 定日期按特定价格交付一定数量单只股票或一揽子 股票的协议。远期股票合约在世界上出现时间不长, 总交易规模也不大。

2.远期外汇协议 远期外汇协议(FXA)是指双方约定在将来某 一时间按约定的汇率买卖一定金额的某种外汇的合 约。 注意,有些国家由于外汇管制,因此本金不可 交割。这种外汇远期合约称为本金不可交割远期 (Non-Deliverable Forwards, NDF)。 远期汇率协议(Exchange Rate Agreements, ERA) (远期的远期外汇协议)
货交易所)合并后形成的CME GROUP(芝加哥
交易所集团),2006年两家交易所交易的合约总
数加起来超过了22亿份,合约总名义本金超过
1000万亿美元 。

❖ 期货交易的基本特征就是标准化和在交易所集 中交易,这两个特征及其衍生出来的一些交易 机制,成为期货有别于远期的关键。
22
❖ 期货市场的第一个运行特征是在有组织的交易所内集中 进行,交易双方并不直接接触,交易所和清算机构充当 所有期货买方的卖者和所有期货卖方的买者,匹配买卖 撮合成交,集中清算。这种交易方式克服了远期交易信 息不充分和违约风险较大的缺陷,在很大程度上提高了 市场流动性和交易效率,降低了违约风险,成为远期交 易进化到期货交易的一个关键。

但相应地,远期合约也有明显的缺点: 首先,没有固定集中的交易场所,不利于信息交流 和传递,不利于形成和发现统一的市场价格,市场 效率较低; 其次,由于非标准,每份远期合约千差万别,给远 期合约的二级流通造成较大不利,因此远期合约的 流动性较差; 最后,履约没有保证,违约风险相对较高。 这些特征,与下一节我们将要介绍的期货合约正好 相反。
如果到期标的资产的市场价格高于交割价格K,远期多头
就会盈利而空头则会亏损;反之,远期多头就会亏损而空头
则会盈利。

案例2.1 人民币即期与远期报价

根据标的资产不同,常见的金融远期合约 包括:
1.远期利率协议 2.远期外汇协议 3.远期股票合约
1212
由于不在交易所集中交易而是由交易双方具 体谈判商定细节 ,双方可以就交割地点、交割 时间、交割价格、合约规模、标的物的品质等细 节进行谈判,以便尽量满足双方的需要。
总的来看,作为场外交易的非标准化合约, 远期的优势在于灵活性很大,可以根据交易双方 的具体需要签订远期合约,比较容易规避监管。
18
股票指数期货、外汇期货、利率期货它们与本 章第一节中所介绍的远期利率协议、远期外汇合约 和远期股票合约的区别都主要体现在交易机制的不 同,我们将在第五章针对不同标的资产的远期和期 货产品作更深入的介绍。
19 19
金融期货合约交易是在现代商品期货交易 的基础上发展起来的。
20世纪70年代初,世界经济环境发生巨大 变化,“布雷顿森林体系”崩溃,世界各国开始 实行浮动汇率制,金融市场上的利率、汇率和证 券价格开始发生急剧波动,整个经济体系风险增 大。人们日益增长的金融避险需求推动了金融期 货交易的产生 。

案例2.5 欧洲美元期货交易的保证金计算与每日盯市结算
❖ 2007年9月20日,投资者A以95.2850的价位购买了一份将于 2007年12月到期的欧洲美元期货合约EDZ7.假设A的经纪人的 保证金要求与CME规定相同,此时一份欧洲美元期货的初始 保证金为743美元,维持保证金为550美元。
❖ 9月20日交易结束时EDZ7结算价为95.2650.这意味着多头A在 这一份合约上损失了2*25=50美元(合约规定0.01代表25美 元)。则A的保证金账户余额相应减少了50美元,减少至693 美元。

金融远期合约(Forward Contracts)是指双方约定在未 来的某一确定时间,按确定的价格买卖一定数量的某种金 融资产的合约。在合约中,未来将买入标的物的一方称为 多方(Long Position),而在未来将卖出标的物的一方称 为空方(Short Position)。
16
从本质上说,期货与远期是完全相同的,都 是在当前时刻约定未来的各交易要素。
期货与远期的重要区别就在于交易机制的差 异。与场外交易的非标准化远期合约相反,期货 是在交易所内交易的标准化合约。交易所同时还 规定了一些特殊的交易和交割制度,如每日盯市 结算(Market to Market and Daily Settlement)和 保证金(Margin)制度等。

案例2.2 远期股票合约
❖ 21世纪初,一些以远期股票合约为主要交易形式 的股票回购协议使得礼来和电子资讯系统等公司面临 着巨大的财务风险。与其他许多公司一样,这些公司 通过向员工发放优先认股权作为激励,因此要从市场 上购买本公司股票以满足认股权执行时的需要。在20 世纪90年代的股票市场繁荣时期,这些公司股票价格 强劲上扬。为了控制他们的购买成本,这些公司便与 投资银行签订合同,约定将来以固定价格购买本公司 的股票,显然这就是远期股票合约。
