BIG REVIEW Flashcards
Taylor Rule
r = policy neutral rate + 0.5(exp - trend GDP growth) + 0.5(exp - acceptable inflation)
H-Model
for emerging economies

Fed Model
- EY > treasury yield, ratio > 1 - undervalued
- EY < treasury yield, ratio < 1 - overvalued
CONS: ignores ERP, ignores earnings growth, compares real variable (EY) to nominal value (treasury yield)

Yardeni Model
compares theoretical EY to acutal EY
- EY > fair value yield - undervalued
- EY < fair value yield - overvalued
CONS: assumed r, d varies over time, earnings estimates can be wrong

Q Models
MV/ replacement cost
q > 1 - overvalued
q < 1 - undervalued

CAPE
cyclically adjusted P/E ratio
CAPE > historical avg - overvalued
CAPE < historical avg - undervalued
10 yr avg earnings captures effects of business cycle and inflation
Credit Risk
risk counterparty will default; based on changes in spread
- %Δ value = - D (Δs)
- currency swap CR highest closet to maturity
- int rate or eqty swap CR highest in middle of life
HHI
HHI = Σ market share2
effective # stocks = 1/ HHI
Mean Variance Optimization
optimizer to set AA, min tracking error, max returns; identify corner portfolios
+: considers correlations
-: doesn’t consider BM variance (need to factor into constraints); based on hist values
M2
rf + σmkt * SR
Myopic Loss Aversion
overemphasizing ST potential losses, underemphasizing LT potential gains > risk premium too high
Life Insurance
- bond like HK, insure against mortality risk
- not needed for equity like HK b/c higher risk HK
Corner Portfolios
- on efficient frontier
- move weight from 0% to X% or X% to 0%
- GMVP is starting port (doesn’t always follow 2)
Hedging Foreign Markets
- hedge foreign market risk only: earn Rffor + RFX
- hedge FX risk only: earn Rfdom - Rffor
Effective Beta
%Δ value of portfolio / %Δ value of index
FV of Portfolio AT
Expected Annual Return
D/P - Δs + i + g + ΔP/E
Strategic AA
- portfolio’s general AA, under “normal” conditions
- based on capital market exp and inv obj/ constraints
- LT time horizon
- neg: GIGO
Tactical AA
- exploit perceived capital market arbitrage opp
- based on ST cap market exp
- temporarily deviating from a portfolio’s LT SAA
- neg = volates linear reg assumptions
Return on Leverage
Rlev + borrowed/ equity * (Rlev - Rbor)
Return
- coupon yield
- %Δ price
- manager exp → -DΔy + 1/2C(Δy)2
- credit loss
- curr g/l
Immunization
- PVA = PVL
- min structural risk
- single liab = min convexity
- multiple liab = CA > CL
Duration Gap
- gap = BPVA - BPVL
- BPV = D * V * 0.0001
- # contracts = gap/ BPV
- BPVfut = BPV/ CF
- BPVswap = BPVrec - BPVpaid
Active Return
IC * √BR * σRa * TC
IC = corr btwn factor and HPR
TC = degree of constraints
Duration Matching
balance price and reinvestment risk
- inc yield = ↓ price, ↑ reinv value
- dec yield = ↑ price, ↓ reinv value
Portfolio Construction
- full replication = dec tracking error (need fewer sec)
- optimization = dec tracking error, high turnover
- stratified samping = dec turnover, high tracking error
Active Share
diff btwn portfolio and benchmark; want higher active share b/c paying for active management
0.5 Σ |Wp - Wb|
Active Risk
tracking error b/c factor exposure and idiosyncratic risk
√ [( Σ RA2 )/ ( T - 1 )]
Variance in Portfolio from Asset
- contribution of asset to portfolio var
- Σ wi wj covij
-
contribution of asset to portfolio var (considering index)
- ( wp - wb ) cov
β
systematic risk; value equity and FI sec
ρi,m σi / σm
Covariance
(Econ)
β1 * β2 * σ2
ERP
(Econ)
σp * SRM * corr + premiums
Information Ratio
Active Return/ Active Risk
Asset Class Characteristics
- homogeneous
- mutually exclusive
- diversifying
- contain most of the inv universe
- liquid
Monte Carlo Simulation
- multi-period - incorporate changes (rebalancing, distributions, taxes)
- include path dependency
- visualization of potential outcomes
- doesn’t follow normal distribution
Convexity
- stable curve = sell convexity
- long callable/ putable bonds
- long MBS
- short call/ put options
Benchmark Characteristics
- specified in advance
- appropriate
- measurable
- unambiguous
- relective of manager’s style
- accountable
- investable
