Q

Immunization

A

assets invested to meet liabilities; to min variability in r, replicating 0 coupon bond; need duration and convexity of A/L

  1. cash-flow matching
  2. duration matching
  3. contingent immunization: actively manage surplus, immunization before surplus is neg
  4. horizon match: ST liab = CF match, LT liab = duration match

Q

Duration Matching

A
  • PVA > PVL
  • DA = DL (single liab)
  • BPVA = BPVL (multi liab)
  • min convexity

NO PASSIVE - rebalance regularly

Q

Futures Contracts Req to Close Duration Gap

A

Nfutures cont = duration gap / BPVfutures

BPVfutures = BPVCTD/ CFCTD

contracts = ( ΔD / Df ) * ( Vp / Vf )

Q

Spread Risk

A

spread changes → rates cannot match; PV may not change as expected

example: portfolio yield and liab discount rate differ → diff risk levels

Q

Controlling Risk of FI Bonds

A
  • match modified duration: control for parallel shifts of yield curve
  • match key rate duration: control for nonparallel shift of yield curve
  • match weighting to diff sectors and ratings
  • matching issuer exposure: control for firm specific event risk
17
Q

Portfolio Structures

A
  • bullet: conc in single middle duration
  • ladder: equal par amounts purchased, come due each year
  • barbell: conc in shorter and longer duration
18
Q

Cell Matching

A

matching the primary risk factor (duration) of the benchmark to minimize tracking error

19
Q

ETF

A

exchange traded fund

PROs: inc liquidity, price stability in maturing ETFs, inc convexity

20
Q

Stable Yield Curve Strategies

A
  1. buy and hold
  2. ride the yield curve: buy and sell, repeat
  3. carry trade
  4. sell convexity: buy/ sell options
21
Q

Parallel Shifts in Yield Curve Strategies

A
  • inc rates: dec duration
  • large movement: inc convexity (buy calls and puts, sell callable/ buy putable bonds, barbell portfolio)
22
Q

Nonparallel Shifts in Yield Curve Strategies

A
  • flatten: inc duration; barbell
  • steepen: dec duration; bullet
23
Q

Spreads

A
  • g-spread: YTMb - YTMOTR gb
  • i-spread: YTMb - YTMswap
  • z-spread: added to rf to get PVCF = price
  • OAS: z-spread for options
24
Q

Excess Return

A

s*t - Δs*Dspread - t*p*L

L = loss severity
