Fixed Income Flashcards
Fixed Income Benefits
- diversification - low corr w/ eqty
- regular cash flow
- inflation hedge
- inf linked protects coupon/ principal
- floating coupon protects coupon
Immunization
assets invested to meet liabilities; to min variability in r, replicating 0 coupon bond; need duration and convexity of A/L
- cash-flow matching
- duration matching
- contingent immunization: actively manage surplus, immunization before surplus is neg
- horizon match: ST liab = CF match, LT liab = duration match
Total Return Mandates
target abs return to outpreform index; active return
- pure indexing: little flexibility (bond selection)
- enhanced indexing: some flexibility
- active management: more flexibility
Bond Liquidity
- little hist pricing data: use matrix pricing
- act managers pref more liquid bonds (lower YTM)
- bonds are heterogeneous
- OTC: need to find counterparty
- quality
Bond Return
- yield on income: annual coupon/ bond price
- rolldown return: (proj ending/ beg price) - 1
- manager pred Δ price: -D(Δr) + ½C(Δr2)
- credit losses
- currency g/l
Rolling Yield
yield income + rolldown return
Leverage
using borrowed funds to purchase assets
rlev = ri + [( Vborrowed/ Veqty )*( ri- rb )]
risk: Δ in value collateral and ri - rb
Ways to Achieve Leverage
- repo
- futures
- swaps
- structured finance inst
- sec lending
Duration Matching
- PVA > PVL
- DA = DL (single liab)
- BPVA = BPVL (multi liab)
- min convexity
NO PASSIVE - rebalance regularly
Convexity
magnifies the upside and reduces the downside of price movement b/c changes in rates
Duration Gap
|BPVA - BPVL|
BPVA or L = Duration * Value * 0.0001
Futures Contracts Req to Close Duration Gap
Nfutures cont = duration gap / BPVfutures
BPVfutures = BPVCTD/ CFCTD
contracts = ( ΔD / Df ) * ( Vp / Vf )
Closing Duration Gap with Swap
NP = ΔBPV/ BPVswap
BPVswap = BPVrec - BPVpaid
Swaption
option to enter a swap, pay premium
- payer swaption: SFRswaption < SFRnew; exercise
- rec swaption: SFRswaption > SFRnew; exercise
Spread Risk
spread changes → rates cannot match; PV may not change as expected
example: portfolio yield and liab discount rate differ → diff risk levels
