Fixed Income Flashcards
What is the underlying assumption of the forward pricing model?
That the price of a zero-coupon bond is the equivalent to the price of a forward contract to purchase a zero-coupon bond that matures at the same time.
What is riding the yield curve?
Where the investor earns excess returns as the bond price increases towards par.
What shape must the yield curve be in order to ride it?
Upward sloping.
What is the swap spread and what risk does it represent?
It is the difference between the fixed rate on a swap and the yield on a treasury.
It represents credit and liquidity risk.
What is the formula for TED spread?
TED = (3 Month LIBOR) - (3 Month T-Bill)
What risk does the TED spread indicate?
Overall risk in the economy.
What risk doe the LIBOR-OIS spread indicate?
Credit risk.
What is the segmented markets theory?
That the yield curve is determined by the fact that different groups on investors have preference for specific maturities.
Out of monetary policy uncertainty and inflation uncertainty, which represents long-term and short-term volatility?
Short-term volatility reflects uncertainty over monetary policy.
Long-term volatility reflects uncertainty over inflation.
What does the Ho-Lee model do?
It uses current market prices to find the time-dependent drift that generates the current term structure.
What is the advantage and disadvantage of using a lognormal walk to calibrate a binomial interest rate tree?
Advantage: It ensures non-negative interest rates.
Disadvantage: Volatility is higher at higher interest rates.
What is the term that relates adjacent forward rates in a binomial interest rate tree?
log squared * standard deviation
Will a binomial tree value a bond as the same a) Spot Curve and b) Par Curve used to derive it?
Yes to both.
What is term for buying a bond and selling off the constituent cash flows?
Stripping.
What risk does the OAS reflect?
OAS removes the option risk so the only remaining risks are credit risk and liquidity risk (i.e. The risk of a corporate bond over a treasury)
What is the formula for Market Conversion Premium?
Market Conversion Premium = Implied Conversion Price - Market Price
What is the upside and downside of a convertible bond?
Upside: The bond has a price floor of a straight bond.
Downside: When the stock price is increasing, the bond will underperform due to the conversion premium.
What is the conversion price of a convertible bond?
The trigger price at which it can be converted to an equity share.
What is the formula for effective duration?
Effective Duration = (BV-y) - (BV+y) / 2 * BV0 * y
What is the formula for effective convexity?
Effective Convexity = (BV-y) + (BV+y) - (2 x BV0) / BV0 x y2
If current price is greater than the callable price, will the bond be called?
Yes.
If current price is greater than putable price, will the bond be put?
No.
Which has a higher duration, straight bonds or bonds with options?
Straight bonds.
Callable and putable bonds have lower duration because the options will be exercised if the price moves too far.
Are low coupon bonds likely to be a) Called and b) Put?
They are unlikely to be called as interest rates would have already been low to start with.
They are likely to be put as there is scope for interest rates to increase significantly.
If an option is likely to be exercised, what will be the highest key rate duration - time to maturity or time to exercise.
The duration that corresponds to time-to-exercise.
What convexity do straight bonds, putable bonds and callable bonds have?
Straight Bonds - Positive
Putable Bonds - Positive
Callable Bonds - Negative
