Barbell
What is bull steepener?
Short term interest rates will fall by more than long term rates

Bear flattener
Short rates will rise more than long term rates
Bull flattener
Long term rates will fall by more than short term rates
Callable bond is combination of
Option free bond and a short call option

Define rolling yield
Sum of coupon income and roll down return
Which portfolio has most modified duration?
Barbell
Which has least modified duration?
Bullet
G spread
Bonds ytm (-) interpolated ytm of 2 adjacent maturity on the run government bonds
Yield spread
Bonds ytm minus the ytm of closest on the run government bond
I spread
Bonds ytm minus maturity of interpolated swap fixed rate
Asw spread
Bonds fixed coupon minus the maturity interpolated sfr
Anchoring bias
The anchoring bias is the tendency of the mind to give disproportionate weight to the first information it receives on a topic: initial impressions, estimates, or data, anchor subsequent thoughts and judgments.
Asset liability management strategy
Asset–liability management strategies consider both assets and liabilities in the portfolio decision-making process.
What’s yield curve inversion
Yield curve inversion is an extreme version of flattening in which the spread between long-term and short-term yields-to-maturity falls below zero
What’s immunization
Immunization is the process of structuring and managing a fixed-income portfolio to minimize the variance in the realized rate of return and to lock in the cash flow yield (internal rate of return) on the portfolio
Rules of immunizing a single liability
- Initial portfolio market value (PVA) equals (or exceeds) PVL. (There are exceptions to this for more complex situations where the initial portfolio IRR differs from the initial discount rate of the liability.)
- Portfolio Macaulay duration matches the due date of the liability (D = DL).
- Minimize portfolio convexity (to minimize dispersion of asset cash flows around the liability and reduce risk to curve reshaping).
- Regularly rebalance the portfolio to maintain the duration match as time and yields change. (But also consider the tradeoff between higher transaction costs from morefrequent rebalancing versus the risk of allowing durations to drift apart.)
Rules of immunizing multiple liabilities
- Initial portfolio market value (PVA) equals (or exceeds) PVL. (There are exceptions to this for some situations where the initial portfolio IRR differs from the initial discount rate of the liability.)
- Portfolio and liability basis point values match (BPV = BPVL)
- Asset dispersion of cash flows and convexity exceed those of the liabilities. (But not by too much, in order to minimize structural risk exposure to curve reshaping).
- Regularly rebalance the portfolio to maintain the BPV match of A and L as time and yields change.
Covered bonds
Senior debt obligations of a commercial Bank backed by a pool of mortgages or loans made by the bank.
The key feature of a covered bond is that it provides dual recourse: investors have a claim on both the issuer and the underlying pool of assets if the issuer defaults.

Protection buyer needs to make upfront premium payment to the protection seller at initiation of contract
Structural models
Structural credit models
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.
Reduced form models
Look for relationship between macroeconomic conditions and individual characteristics of a borrower such as financial ratios to infer default intensity for a bond issuer
