期权期货-复习题
复习题一、单项选择题(在每题给出的4个选项中,只有1项最符合题目要求,请将正确选项的代码填入括号内)1.金融期权合约是一种权利交易的合约,其价格( C )。
A.是期权合约规定的买进或卖出标的资产的价格B.是期权合约标的资产的理论价格C.是期权的买方为获得期权合约所赋予的权利而需支付的费用D.被称为协定价格【解析】金融期权是一种权利的交易。
在期权交易中,期权的买方为获得期权合约所赋予的权利而向期权的卖方支付的费用就是期权的价格。
2.标的物现价为179.50,权利金为3.75、执行价格为177.50的看涨期叔的时间价值为( B )。
A.2B.1.75C.3.75D.5.75【解析】期权的价格即权利金是由两部分构成,一部分是内在价值(立即执行所带来的价值和0取最大),一部分是时间价值,本题内在价值为2,时间价值为3.75-2=1.753.买进执行价格为1200元/吨的小麦期货买权时,期货价格为1190元/吨,若权利金为2元/吨,则这2元/吨为( B )。
A.内涵价值B.时间价值C.内在价值+时间价值D.有效价值【解析】虚值期权无内涵价值,只有时间价值。
4.下列说法错误的是( B )。
A.对于看涨期权来说,现行市价高于执行价格时称期权处于实值状态B.对于看跌期权来说,执行价格低于现行市价时称期权处于实值状态C.期权处于实值状态才可能被执行D.期权的内在价值状态是变化的【解析】对于看跌期权资产现行市价低于执行价格时称为期权处于“实值状态”。
由于标的资产的价格是随时间变化的,所以内在价值也是变化的。
5.期权价值是指期权的现值,不同于期权的到期日价值,下列影响期权价值的因素表述正确的是( A )。
A.股价波动率越高,期权价值越大B.股票价格越高,期权价值越大C.执行价格越高,期权价值越大D.无风险利率越高,期权价值越大【解析】 B、C、D三项都要分是看涨期权还是看跌期权,不能笼统而论。

期权、期货课后题答案
第1章引言1.3远期合约多头与远期合约空头的区别是什么?答:持有远期合约多头的交易者同意在未来某一确定的时间以某一确定的价格购买一定数量的标的资产;而持有远期合约空头的交易者则同意在未来某一确定的时间以某一确定的价格出售一定数量的标的资产。
1.6某交易员进入期货价格每磅50美分的棉花远期合约空头方。
合约的规模是50000磅棉花。
当合约结束时棉花的价格分别为(a)每磅48.20美分,(b)每磅51.30美分,对应以上价格交易员的盈亏为多少?答:(a)此时交易员将价值48.20美分/磅的棉花以50美分/磅的价格出售,收益=(0.50 00-0.482)×50000=900(美元)。
(b)此时交易员将价值51.30美分/磅的棉花以50美分/磅的价格出售,损失=(0.513 -0.500)×50000=650(美元)。
1.9你认为某股票价格将要上升,股票的当前价格为29美元,而3个月期限,执行价格为30美元的看涨期权价格为2.90美元,你总共有5800美元的资金。
说明两种投资方式:一种是利用股票,另一种是利用期权。
每种方式的潜在盈亏是什么?答:在目前的资金规模条件下,一种方式为买入200只股票,另一种方式是买入2000个期权(即20份合约)。
如果股票价格走势良好,第二种方式将带来更多收益。
例如,如果股票价格上升到40美元,将从第二种方式获得2000×(40-30)-5800=14200(美元),而从第一种方式中仅能获得200×(40-29)=2200(美元)。
然而,当股票价格下跌时,第二种方式将导致更大的损失。
例如,如果股票价格下跌至25美元,第一种方式的损失为200×(29-25)=800(美元),而第二种方式的损失为全部5800美元的投资。
这个例子说明了期权交易的杠杆作用。
1.12解释为什么期货合约既可以用于投机也可以用于对冲。
答:如果一个交易员对一资产的价格变动有风险敞口,他可以用一个期货合约来进行对冲。

()正确答案:对参考解析:期权头寸的建立即开仓,包括买入开仓和卖出开仓。
