如果risk neutural default等于8%的方法计算,real world probabily:
92=100(1-pd)/(1+1.5%+2%+1.5%)计算出来不是5%
而且问计算risk neutural default的时候用spread的方法算,YTM=8.6%-2.5%=PD算出来也不等于8%
那么问题如下图:
选项:
A.
B.
C.
D.

NO.PZ2016082405000067 B The risk-neutrfault probability is approximately 8% because the market priis 92% of par. risk-neutrprobability = real-worlprobability + cret risk premium + liquity premium 8% = real-worlprobability + 2% + 1% real-worlprobability = 8% - 3% = 5% 可以具体下The risk-neutrfault probability is approximately 8% because the market priis 92% of par.么? 如果按照讲义上的风险中性p计算方法如下,计算出来是5.7%,请问这个方式有什么问题么? p=100(1-p/1+risk_free_rate 92=100*(1-p/1+0.025
NO.PZ2016082405000067 8% 5% 6% 8% 5% 6% B The risk-neutrfault probability is approximately 8% because the market priis 92% of par. risk-neutrprobability = real-worlprobability + cret risk premium + liquity premium 8% = real-worlprobability + 2% + 1% real-worlprobability = 8% - 3% = 5% 真实pπ这个规律可以直接使用吗

B The risk-neutrfault probability is approximately 8% because the market priis 92% of par. risk-neutrprobability = real-worlprobability + cret risk premium + liquity premium 8% = real-worlprobability + 2% + 1% real-worlprobability = 8% - 3% = 5% 这个inflation rate只是一个干扰项吧?
B The risk-neutrfault probability is approximately 8% because the market priis 92% of par. risk-neutrprobability = real-worlprobability + cret risk premium + liquity premium 8% = real-worlprobability + 2% + 1% real-worlprobability = 8% - 3% = 5% 我的只能理解,中性定价里面,所有的sprea对CR进行补偿,这个时候CR大了,所以P,如果是objective的话, sprea止对CR进行补偿,还有别的东西,所以,P对就低了。就是扫一眼知道选B , 还是不太明白你放的那个图,和这句话是怎么补偿的。讲道理RISK NATURP 1+3+2=6%,这个东西应该是sprea概念 如果套用这题,sprea 8%-2.5%=5.5%,如果是risk natur的话5.5%全部补偿CR了,再减去1%的流动性4.5%就是objective 但是这么硬算又找不到答案。。。
