Term

Twists refer to:

Definition

yield curve changes when the slope becomes either flatter or more steep. A flattening (steepening) of the yield curve means that the spread between short- and long-term rates has narrowed (widened).

Term
Calculate the duration of a bond using interest rate tree
Definition

parallel shift up and down of the yield curve

 

The usual method is to apply parallel shifts to the yield curve, use those curves to compute new sets of forward rates, and then enter each set of rates into the interest rate tree. The resulting volatility of the present value of the bond is the measure of effective duration. 

Term

A sequential-pay CMO is structured so that each class of bond:

Definition

is retired sequentially

 

When there are prepayments, the principal in the first bond class (tranche) is reduced until it is fully retired, then the principal of the next bond class is retired, and so on.

Term

The no-arbitrage price of a futures contract (formula)

Definition

FP

= S0 × (1 + Rf)T

 

S = spot rate

Term

Annualized yield volatility (formula)

Definition

 

Annualized yield volatility = σ × sqrt(#trading days per yr)

 

where:
σ = the daily yield volatility

 

Term

Key rate duration can be defined as:

Definition

the approximate percentage change in the value of a bond or bond portfolio in response to a 100 basis point change in a key rate, holding all other rates constant, where every security or portfolio has a set of key rate durations, one for each key rate maturity point.

Term

Important considerations of the issuer’s character include (6 things):

Definition

(1) strategic direction

(2) financial philosophy

(3) conservatism

(4) track record

(5) succession planning

(6) control systems

Term
Priority of debt order:
Definition

First lien loans

secure bonds

senior subordinated debt

subordinated debt

unsecured debt

Term

Market Conversion Price of a convertible security (formula):

 

Premium over straight price (formula):

Definition

market conversion price =

market price of convertible bond ÷ conversion ratio. 

 

POSP = (market price of bond) / (straight value) − 1

Term

Calculate price of forward contract on Treasury bond (with coupon payment paid in x days)

Definition

The forward price is calculated as the bond price minus the present value of the coupon, times one plus the risk-free rate for the term of the forward.

 

(1,000 – (PMT/2)/(1+r)x/365) (1+r)t/12 = $1,001.84

t = length of forward contract

Term

The liquidity theory

Definition

Forward rates reflect investors’ expectations of future rates plus a liquidity premium to compensate them for exposure to interest rate risk, and this liquidity premium is positively related to maturity. The implication of the liquidity theory is that forward rates are a biased estimate of the market’s expectation of future rates, since they include a liquidity premium.

Term
The four "C's" of credit analysis
Definition

capacity, collateral, covenants, and character

Term

How do the risk-return characteristics of a newly issued convertible bond compare with the risk-return characteristics of ownership of the underlying common stock?

The convertible bond has __ risk and __ return potential.

Definition
LOWER risk LOWER return potential
Term

All things equal, highest OAS:

Bond with (highest/lowest) price

(Call/put)able bond with (high/low)est rating

Definition

Lowest price

 

Callable bond with lowest rating

Term
Average historical spread between AAA and BBB bonds
Definition
100 basis points
Term
Accrual bonds
Definition

For many sequential-pay CMO structures, the last tranche to be paid principal also does not receive current interest until the other tranches have been paid off. This tranche is called the Z-tranche or accrual tranche, and the securities that represent a claim against its cash flows are called Z-bonds or accrual bonds. The interest that would ordinarily be paid to the accrual tranche is applied against the outstanding principal of the other tranches, in sequence. The diverted interest from the accrual tranche accrues. That is, it is added to the outstanding principal balance of the Z-tranche.

Term

A convertible bond underperforms the underlying common stock when that stock ______ in value

Definition

Increases in value

 

This is because of the conversion premium which means that the bond will increase less than the increase in stock price. If the stock price falls, the convertible bond should outperform the stock because of the floor created by the straight-value. If the stock is stable, the bond is likely to outperform the stock because of the higher current yield of the bond. If the bond is upgraded, the bond should increase in value. There is no reason that upgrading the bond should lead to the bond underperforming the stock.

Term

The historical yield volatility method uses the ______.

 

The implied yield volatility method uses ______

Definition

the standard deviation formula

 

derivative prices

Term

Definition

(4) 1 - Expected loss

Term
Yield spread
Definition
=Liquidity premium + credit spread
Term
Return impact of spread changes (formula):
Definition

(approx.) = 

 

-duration * Delta(Spread) + [1/2*Convexity*Delta(Spread)2]

Term

Theories of Term Structure:

(1) Pure (unbiased) expectations

(2) Liquidity theory

(3) Preferred habitat theory

Definition

(1) Forward rates are a function of expected future spot rates

 

(2) Forward rates reflects expectations of expected future spot rates plus liquidity premium

 

(3) Imbalance between fund supply/demand at maturity range induces lenders to shift from preferred habitats to one with opposite imbalance

Term
