三、名词解释

1、套利

答:套利是在某项金融资产的交易过程中,交易者可以在不需要期初投资支出的条件下获取

无风险报酬。

2、阿罗-德不鲁证券

答:阿罗-德不鲁证券指的是在特定的状态发生时回报为1,否则回报为0的资产。

3、等价鞅测度

答:资产价格st是一个随机过程,假定资产价格的实际概率分布为p,若存在另一种概率

分布p使得以p计算的未来期望风险价格经无风险利率贴现后的价格序列是一个鞅,即**

ste?rt?et(st??e?r(t??)),则称p*为p的等价鞅测度。

四、计算题

1、每季度计一次复利的年利率为14%,请计算与之等价的每年计一次复利的年利率和连续

复利年利率。解:利用复利计算公式:1??r4

m?rm ?1?r,rc?mln1?m??

每年计一次复利的年利率=(1+0.14/4)4-1=14.75%

连续复利年利率=4ln(1+0.14/4)=13.76%。

2、一只股票现在价格是40元,该股票一个月后价格将是42元或者38元。假如无风险利

率是8%,分别利用无风险套利方法、风险中性定价法以及状态价格定价法计算执行价格为

39元的一个月期欧式看涨期权的价值。

f是看涨期权价格。f=1.69。

风险中性定价法:按照风险中性的原则,我们首先计算风险中性条件下股票价格向上变动的

状态价格定价法:d=38/40=0.95,u=42/40=1.05,从而上升和下降两个状态的状态价格分别1?de?r(t?t)1?0.95e?0.08/12

??0.5631,为:?u?u?d1.05?0.95

ue?r(t?t)?142/40e?0.08/12?1?d??=0.4302u?d42/40?38/40

3、一只股票现在价格是100元。有连续两个时间步,每个步长6个月,每个单步二叉树预

期上涨10%,或下跌10%,无风险利率8%(连续复利),求执行

价格为100元的看涨期权

的价值。

险中性概率。该股票和以该股票为标的资产的期权的价格变化如下

三、名词解释

答: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。

2、safe

四、计算题

1、某股票预计在2个月和5个月后每股分别派发1元股息,该股票目前市价等于30,所有

期限的无风险连续复利年利率均为6%,某投资者刚取得该股票6

个月期的远期合约空头,

请问:?该远期价格等于多少?若交割价格等于远期价格,则远期合约的初始值等于多少?

?3个月后,该股票价格涨到35元,无风险利率仍为6%,此时远期价格和该合约空头价值

等于多少?

答:(1)2个月和5个月后派发的1元股息的现值=e-

0.06?2/12+e-0.06?5/12=1.96元。

远期价格=(30-1.96)e0.06?0.5=28.89元

若交割价格等于远期价格,则远期合约的初始价格为0。

(2)3个月后的2个月派发的1元股息的现值= e-0.06?2/12=0.99元。

远期价格=(35-0.99)e0.06?3/12=34.52元

此时空头远期合约价值=(28.89-34.52)e-0.06?3/12=-5.55元。

2、假设目前白银价格为每盎司80元,储存成本为每盎司每年2元,每3个月初预付一次,

所有期限的无风险连续复利率均为5%,求9个月后交割的白银远

期的价格。

答:9个月储藏成本的现值=0.5+0.5e-0.05?3/12+0.5e-

0.05?6/12=1.48元。

白银远期价格=(80+1.48)e0.05?9/12=84.59元。

3、1992年11月18日(交易日),一家德国公司预计在1993年

5月份需要500万德国马克

资金,由于担心未来利率上升,于是当天签订了一份名义本金为

500万德国马克的fra,

合约利率为7.23%,合约期限为186天。在确定日1993年5月18日,德国马克的libor

固定在7.63%的水平上。假定公司能以7%的利率水平投资。在

1993年5月18日,公司可

以按当时的市场利率加上30个基本点借入500万德国马克,这一

协议是结算日1993年5

月20日签订的,并于186天后在最终结算日11月22日进行偿付。计算净借款成本及相应

的实际借款利率。

从fra中获得的总收入:(9941.43+359.55)=10300.98

与净借款成本相应的实际借款利率7.53% = 194557.35/ 5000000/ (186/360 )

4、假设6个月期利率是9%,12个月期利率是10%,求:

(2)当6个月利率上升1%时,fra的价格如何变动;

(3)当12个月利率上升1%时,fra的价格如何变动;

1、转换因子

答:芝加哥交易所规定,空头方可以选择期限长于15年且在15年

内不可赎回的任何国债用于交割。由于各种债券息票率不同,期限

也不同,因此芝加哥交易所规定交割的标准券为期限15年、息票率

为6%的国债,其它券种均得按一定的比例折算成标准券。这个比例

称为转换因子。

2、利率期货

期国债期货、短期国债期货和欧洲美元期货。

的红利收益率每年为5%,3个月期的标准普尔指数期货的市价为

950点,3个月期无风险连续复利年利率为10%,3个月后指数现货

点数为1100点。请问如何进行套利?(复利计算)

解:由题知:

s?1000?250?250000美元

q?5%,r?10%,t?t?3/12?1/4

g?950?250?237500美元

由“期货定价”知:

理论价格:k?s?e(r?q)(t?t)?250000?e(10%?5%)/4?253144.61美

∴投资者可以进行无风险套利。

具体操作:投资者可以卖空该股票指数的成分股,同时将所得收入

以r-q的利率进行投资,期限为3个月。另外买入相应的股指期货。则到期时,投资者收到投资本息253144.61美元,并以237500现

金购买股票以归还卖空的资产,从而获得253144.61-

237500=15644.61美元的无风险利润。

2、假设xx年12月15日,某公司投资经理a得知6个月后公司将

会有一笔$970,000的资金流入并将用于90天期国库券投资。已知

当前市场上90天期国库券的贴现率为12%,收益曲线呈水平状(即

所有的远期利率也均为12%),明年6月份到期的90天国库券期货合约的价格为$970,000。请说明如何进行套期保值。

3、假定我们已知某一国债期货合约最合算的交割券是息票利率为14%,转换因子为1.3650的国债,其现货报价为118美元,该国债

期货的交割日为270天后。该交割券上一次付息是在60天前,下一

次付息是在122天后,再下一次付息是在305天后,市场任何期限
