Q

What is an arbitrage strategy?

A

An arbitrage strategy always has two sides: financing (where the money comes from) and the investing side (what you do with the money). It needs to yield payofft»0 with at least one positive payoff, without any kind of risk (investor can’t use their own money). It appears from misspricing in the financial market.

Q

How do we price bonds?

A

Through the present value of all future cash-flows.
P0 = C1/(1 + y) + C2/(1 + y)^2 + (CT + FV) / (1 + y)^T

Q

What is the relationship between the bond’s price and the discount rate?

A

Convex. If the probability to not receive face value decreases, you increase the discount rate (as you’re closer to maturity date you increase by less)

Q

What does it mean to assume the financial markets are normal?

A

Financial assets are traded with NPV=0 so the bond’s price and its value are the same, so there are no arbitrage opportunities.

Q

What are spot rates?

A

Spot rates are a set of discount rates applicable today and for different maturities. We use them to get the bond’s value. Spot rates allow you to value bonds with the same risk in a specific point in time.

Q

What is the YTM?

A

A YTM is a discount rate that sets the present value of the promised payments equal to the current market price of the bond. It is the return you earn as an investor from holding the bond from the moment you buy it until maturity.

Q

What is the relationship between spot rated and the YTM?

A

The YTM is a non-linear average of the spot rates that the bond uses (higher than the lowest and lower to the highest) The YTM is relatively closer to the last spot rate that the bond uses (the one with the highest weight).

Q

Why is it indifferent if you buy a bond at premium or discount?

A

If you demand a YTM higher than the coupon rate (what the bond pays you) the price will decrease.

Q

How do we find the spot rate with zero-coupon bonds?

A

In zero-coupon bonds the spot rate is the same as the YTM, assuming normal markets.

33
Q

How is the investor compensated in zero-coupon bonds?

A

The price is lower than the face value.

34
Q

What are the conditions to use bootstrap?

A

It can’t be a zero-coupon bond, we need to know the price and n-1 spot rates.

35
Q

What are forward rates?

A

Rates that are acquired today but will be used in the future.

36
Q

What is the formula for forward rates and spot rates?

A

(1 + 0r3)^3 = (1 + 0r2)^2 * (1 + 2f3)
(1 + 0r3)^3 = (1 + 0r1) * (1 + 1f2) * (1 + 2f3)

37
Q

What is the yield curve?

A

A graph of spot rates.

38
Q

What is the liquidity preference theory?

A

Liquidity Preference Theory can only explain yield curves (or segments of the yield curve)
that have an upward slope. The theory suggests that investors like to hold cash (liquidity)
hence the higher the bond’s maturity the higher the return that they demand.

39
Q

What is the expectation theory?

A

Expectation Theory: Investors make expectations regarding the future. If those expectations make investors believe that spot rates are going to be higher (lower) in the future than what they are today, the yield curve today will present an upwards (downwards) slope. This theory can explain segments of the yield curve that have upwards (downwards) slope.

40
Q

What is the probability of default?

A

The likelihood that a borrower will fail to pay.

41
Q

What can be used to measure the probability of default?

A

Credit rating

42
Q

What is the effect of time on bond prices?

A

Between coupon payments, the prices of all bonds rise as the remaining cash flows become closer. When the bond is issued at premium, the price drop when a coupon is paid is larger than the price increase between coupons. The prices of all bonds approach the bond’s face value when the bonds mature.

43
Q

What is the duration?

A

A bond’s duration measures the sensitivity of a bond’s price to changes in interest rates. The duration tells us the average maturity of the bond’s payments.

44
Q

How is duration related to the coupon rate?

A

Everything else constant, duration is inversely related with bond’s coupon rate.

45
Q

What is the duration’s formula?

A

Duration = (1* C1/(1 + YTM) + 2 * C2/(1 + YTM)^2 + … + T * (CT + FV)/(1 + YTM)^T))/P0

46
Q

What is the modified duration?

A

The modified duration tells us the change in value of a bond due to a change in interest rates. If a bond has a higher modified duration it’s more sensitive.

47
Q

What is the modified duration formula?

A

D/(1 + YTM)

A

True

57
Q

True or false: A bond’s YTM is the return achieved from the bond since the point that it was issued until maturity.

YTM the lower will be the price).

A

True

61
Q

True or false: . According to the Liquidity Preference Theory, the higher the maturity of a bond’s payment the higher the return demanded by investors.

A

True

62
Q

True or false: When you can explain the yield curve with the Liquidity Preference Theory you can
also explain it with the Expectation Theory.

True or false: If all spot rates suddenly increase by 1 percentage point, the bond’s price decreases
approximately by its duration in percentage.

A

A

False

66
Q

True or false: Spot rates can be used to find the price of any bond with the same type of risk.

A

False

67
Q

True or false: Spot rates determine the interval for a bond’s YTM, assuming efficient markets. This means that, under efficient markets, a bond’s YTM is always higher than lowest spot rate, and lower than the last spot rate that the bond uses.
