25
Structural credit model
+ use market-based variables to estimate the market value of an issuer’s assets and the volatility of asset value. + The likelihood of default is defined as the probability of the asset value falling below that of liabilities.
26
reduce form model
solve for default intensity, or the POD over a specific time period, using observable company-specific variables such as: + financial ratios + recovery assumptions as well as macroeconomic variables, including: + economic growth + market volatility measures
27
Default intensity
it is hazard rate, the probability of default for a certain time period conditional on no earlier default
28
bottom-up credit strategy
finding the best issuer/individual bond investment rather than focus on macro-enviroment + Step 1: identify universe of bond relevant to mandate + Step 2: divide universe into sectors such as undustry/ geography + Step 3: looking for relative misvaluation to determine securities to select Credit analysis is assessment the likelyhood of issuer making scheduled principal + interest payment, include: + Operating history + competitive position of the issuer + Financial ratio include: profitability, leverage, coverage ratio
29
Top-down credit strategies
+ focus on macro factors that affect the credit portfolio (strength of economic growth, corporate profits) + Use: * indentify when focus on HY / IG * sectors most likely to improve -> can overweight this factors
30
factor-based credit strategies
use style-based factors, identify as offering risk premium in coporate bond investing. 4 factors: + Carry -> OAS + Defensive: -> risk adjust return + Momentum: outperform go on to outperform in the future + Value
31
conditional Var
expected loss
32
incremental VaR
impact of change in portfolio position
33
relative VaR
measure expected tracking error versus benchmark portfolio
34
CDS Price
= 1 + (Fixed Coupon - CDS Spread) x EffSpreadDu
35
CDS curve
plot of CDS spread across maturities
36
static Credit spread curve strategy
hypothesis: credit spread curve remain unchange method: + lowering the average credit rating of bond portfolio + increasing spread duration by buy + hold longer-dated bond + sell protection
37
Dynamic credit spread strategy
base on credit cycle to buy/sell bond/protection
38
Global credit strategy
based on: + diversify through investing in different sectors + sector difference exist between developed market + difference in accounting standard + difference in credit manitude & timing related to credit cycle
39
credit structured
CDOs, CLOs, MBS, ABS, Covered Bonds
40
user-defined parameter
include: + models for term structure, risk, + scenario analysis + filter for include/exclude bonds by sectors/ESG ratings.
41
rule to immunize a single liability
(1) portfolio market value (PVA) equals (or exceeds) PVL (2) Portfolio Macaulay duration matches the due date of the liability (DA = DL) (3) Minimize portfolio convexity (to minimize dispersion of asset cash
42
Matching issuer exposure weights
to control for specific event risk affecting only that issuer, such as bankruptcy
43
bums problem
bum is a less creditworthy issuer
44
Immunized Portfolio Convexity
= (Mac Du ^2 + Mac Du + Dispersion) / (1 + CF Yield)^2
45
money duration
A measure of the price change in units of the currency in which the bond is denominated. Money duration can be stated per 100 of par value or in terms of the bond’s actual position size in the portfolio BPV = Money Du x 0.01%
46
dollar duration
it is money duration
47
Duration drift
Duration drift is the change of duration due to the passage of time Eg: The duration drift has arisen because of a widening spread between corporate and government bond yields as interest rates in general have come down.
48
Butterfly spread
butterfly spread is equal to twice the medium-term yield minus the short-term and long-term yields,
48
Butterfly spread
butterfly spread = 2 x the medium-term yield - (the short-term + long-term yields) + Humped + Sauce + butterfly spread / butterfly /twist
49
Immunizing with coupon-bearing bonds
continuously matching the portfolio Macaulay duration with the Macaulay duration of the zero-coupon bond over time and as the yield curve shifts, even though the zero-coupon bond could be hypothetical and not exist in reality
50
A duration-neutral flattening trade
involves a short short term bond position and a long long term bond position, which have a “matched” duration or portfolio duration of zero
51
Flight to quality
Thị trường sập, quay sang mua tài sản tốt market stress scenario, investors sell high-risk, low-rated bonds, which fall in price, and purchase government bonds, which experience price appreciation
52
roll down return vs rolling yield
Rolling yield = roll down return + coupon income
53
goals of credit strategies
choose maximize credit spread across issuer types, industry,... within predescribe investment mandate
54
method to hedge the tail risk
Reduce tail risk: + Position limits + Risk budgeting Hedge tail risk: + Swaption + CDS
55
QM (description, Adv, disadv)
1. Description: Yield of original FRN - MRR 2. Advantage: Represents periodic spread related FRN cash flow 3. Disadvantage: Does not capture changes in credit risk over time
56
DM (description, Adv, disadv)
1. Description: Yield to price FRN at par - MRR 2. Advantage: Establishes spread difference from QM with constant MRR 3. Disadvantage: Assumes a flat MRR zero curve
57
Z - DM (description, Adv, disadv)
1. Description: Yield spread over MRR curve 2. Advantage: incorporate forward MRR rates in yield spread measure 3. Disadvantage: more complex calculation and yield spread does not match FRN cash flow
58
The meaning of Credit excess spread return
(1) negative is not efficiency (2) higher excess spread return -> more attractive
59
CDOs (description, exposure, application)
(1) Description: backed by a diversified pool of debt obligations (2) Exposure: Redistribute portfolio debt cash flows across ratings spectrum (3) Create tailored portfolio-based debt exposure categories/profiles unavailable in the cash bond market
60
CLOs (description, exposure, application)
(1) Description: backed by a diversified pool of floating-rate leveraged loan obligations. (2) Exposure: Redistribute portfolio loan cash flows across ratings spectrum. (like CDOs) (3) Create tailored portfolio-based debt exposure categories/profiles unavailable in the cash bond market (like CDOs)
61
MBS (description, exposure, application)
(1) Description: a pool of commercial or residential mortgage loans. (2) Exposure: Provide portfolio-based exposure to real estate cash flows (3) Offer active managers exposure to real estate and to volatility (prepayment/extension risk) unavailable in the cash bond market
62
ABS (description, exposure, application)
(1) Description: pool of credit card, auto, and other loans (2) Exposure: Provide portfolio-based exposure to consumer loan cash flows (3) Offer active managers direct exposure to consumer loans and to volatility unavailable in the cash bond market
63
Covered Bonds
(1) Description: Senior debt obligations backed by pool of commercial/residential mortgages or public sector assets (2) Exposure: Provide portfolio-based exposure to real estate cash flows with recourse to issuer (dual recourse) (3) Offer active managers direct exposure to consumer loans and to real estate/public sector cash flows unavailable in the cash bond market
64
dual recourse
specify by covered bond (bảo vệ 2 lần)
65
how to increase convexity
(1) Long putable, Long calls, Puts (2) Short callable, short MBS
66
Standardized of Fixed coupon HY CDS contract and IG CDS contract
IG CDS contract: 1% HY CDS contract: 5%
