嗨,努力学习的PZer你好:


1.volatility

long MBS=long option free bond+short call option on the bond。

call option 与volatility,如果short option,意味着预期volatility下降。

2.correlation

default correlation是CDO不同层级之间的违约相关系数,default correlation越大,意味着CDO的优先、夹层、劣后都有可能违约或者都有可能不违约。default correlation越小,意味着CDO的越劣后,违约的可能性越大,越优先,违约的可能性越小。

所以,预期default correlation上升,应该buy更劣后级别的份额,sell更优先级别的份额,

原因是:如果优先于劣后都违约了,但劣后肯定卖的便宜,所以劣后的更好;如果优先与劣后都不违约,那么买劣后有更高的收益,但并没有真正违约,也是劣后的更好。

反之,如果预期default correlation下降,应该buy更优先的份额,sell更劣后的份额。
