| americade | so will a z tranche (have shorter duration) |
| danlan2 | Support tranche is exposed to such risk. |
| PhiWong | Should the supporting tranche absorb any prepayment and hence it has higher interest rate risk. The value of the supporting tranche will fall faster than the PAC tranche? |
| PhiWong | Excess principal payment received by support tranche faces reinvestment risk since this tranche holder will have to reinvest in lower interest rate. |
| ehc0791 | From short duration perspective, the interest rate risk is lower. However, reinvestment risk is higher. |
| ramdabom | What not z/accrual tranche as well? |
| rana1970 | Guys, Question is specifically asking for interest rate risk, not the reinvestment risk, not even the total risk. Well actually I think a support trenches holder will be happy to rise in price due to fall in interest rate. Isn't it? Comment please? |
Thanks again for your wonderful site ... it definitely made the difference.
