- YTM涵义:YTM是多期Spot Rate的Weighted Average
- FIxed Income策略:
- 第一种是交易Forward contract来锁定未来期限的收益率;
- 第二种是riding the yield curve/ rolling down the yield curve, 假设是yield curve upwarding,操作是持有maturity大于investment horizon的bond
- Bootstrapping是已知Par Rate Curve倒推Spot Rate Curve的方法
- Swap Rate 等于Par Rate; Swap优点是流动性好(国债只有on-the-run的流动性好),Maturity弹性(美国国债只有11个期限),有default risk就与公司债相同(所以是好的benchmark),没有管制
- 各种信用利差
- Swap Spread = Swap Rate - Treasury Yield(on-the-run),风险补偿 Default risk, Liquidity risk
- I-Spread = Bond Rate - Swap Rate, 风险补偿Credit, Liquidity Risk,期限采用linear interpolation
- Z-Spread = Spot Bond Rate - Spot Treasury Rate,风险补偿credit and liquidity risk,对于公司债来说比GSpread衡量准确
- TED Spread = LIBOR - T-Bill Rate, 风险补偿银行系统间的风险(risk in the banking system)以及对手风险(Counterparty risk)
- Libor-OIS Spread = Libor - overnight indexed swap(1天),反映money market的risk
- 不熟悉的Yield Curve Theory(定性)
- Prefered Habitat Theory,投资者有自己投资期限的偏好,只有另一个期限的补偿足够多才回去投资另一期限;
- 对比segmented market,投资某一期限的投资者不会进入不同的期限投资
