Chapter 8 Flashcards
What are the major responsibilities of a fixed income portfolio manager?
- creating investment mandate, goals, guidelines/restrictions
- developing an executing FI strategy
- providing timely information to the head of FI markets
- supervising staff and traders
- providing information marketing and client service dept
- focus on economic analysis, monetary policy, and overall creation of FI strategy
A trader has a narrower range of responsibilities then a fixed income manager. A trader’s major responsibilities include:
- effective/best execution
- remain informed about strategy
- keep PM updated on bond market conditions and trends
- maintain relationships with FI sales and trading staff
- trader often serves as a PM’s “ear to the market”
What is a repo transaction?
- a sale/repurchase agreement wherein a broker/dealer sells a FI security to a third a party on a specific day, at a specific price and simultaneously agrees to buy it back at a set price on a future day
- traders and market makers at brokers/dealers normally leverage their FI portfolios by using repo transactions
- usually spans one day but can be as long as a week
What are the primary and secondary occupational goals of a fixed income trader at a broker/dealer (sell side)?
primary: absolute performance (earn highest capital gains from trading operations)
secondary: increase market share of trading activity with institutional investor target market
What are the primary and secondary occupational goals of an institutional FI PM (buy side)?
- primary: relative performance (rank as high as possible in appropriate peer performance analysis)
- secondary: contribute to growth of firm’s AUM by supporting sales/marketing efforts and client service activities
What are the tertiary occupational goals/performance factors for the buy side and the sell side?
Sell side: assist with the growth and profitability of the firm’s fixed income underwriting operations by providing counsel regarding market conditions and new issue pricing
Buy side: contribute to the firm’s growth through the support of new product design and launches
With a normal (rising) yield curve, _____ maturities will have _______ yields and be _____ attractive.
- long
- higher
- more
Describe passive bond management
- minimizes the effects of interest rate risk on a bond portfolio
- no attempt is made to predict the direction or magnitude of interest rates
Describe active bond management
-attempts to profit from interest rate risk by predicting the direction or magnitude of rate changes
Describe Interest rate risk
- the variation in bond values due to changes in market yields
- contains price risk and reinvestment risk
What factors about a bond increase sensitivity to changes in interest rates?
- long maturity
- low coupon
What are the three applications of duration?
- primary use is to capture effective average maturity
- measures the sensitivity of a bond’s price to changes in interest rates
- aids in immunizing against interest rate sensitivity
A bond portfolio’s modified duration has what 5 general properties?
- it is the dollar weighted sum of individual bond modified durations
- the proportional change in a bond’s price following a yield change is the product of modified duration and the change in a bond’s yield to maturity (change in price= (-ModDur) * change in yield)
- For the same maturity , the higher a bond’s coupon, the lower its ModDur
- For the same maturity, the higher a bond’s YTM, the lower its ModDur
- For the same coupon, the longer a bond’s term to maturity, the greater its ModDur (except maybe it is trading at a discount)(because early payments become more relevant in the calculation)
What is a ModDur formula?
=MacDur/(1+(y/k))
What are the two portfolio structures that achieve the goal of receiving a yield to maturity that is equal to a bond’s original coupon rate or YTM at the time of purchase?
- Barbell portfolio
2. Laddered portfolio
Describe a barbell portfolio
- bonds are initially purchased at both ends of the term structure (assuming 1-30 barbell) and then each year new one year bonds are purchased to maintain the short end as the old ones mature. at the same time, as the maturity of the long bonds decreases to 29 years, they are sold and replaced by new 30 year bonds (if yield curve is rising it would be sold at a slight premium
- offers more flexibility for accommodating cash than laddered
Describe a laddered portfolio
- bonds are initially purchased with each maturity up to 30 years in equal proportions
- after Y1, the original one year bonds mature and are replaced by the original two year bonds which now have one year to maturity
- portfolio is replaced by replacing the longest maturity bond
What are the two methods used to replicate a bond index?
- cellular (stratified sampling)
2. tracking error minimization
Describe cellular replication method
- the attributes that can describe a bond universe are maturity, coupon, and credit risk
- the percentage of the bond universe that exists within each cell is applied to the funds total capital and representatives of each cell are bought in proportion
- a bond index fund is achieved by creating a cellular portfolio designed with cells in each of the three attributes containing representative bonds in proportions that match the market proportions of the bonds in each cell
- drawback: matching some cells is more critical than matching others because volatility associated with them is higher and also this method ignores correlations between cells
Describe tracking error minimization method
- uses historical data to model the tracking error variance for each bond in an index, then minimizes the model’s total tracking error
- a bond’s tracking error is statistically estimated as a function of its cash flows, duration, and other sector characteristics
- quadratic programming is applied
- drawback: limited to historical data (can miss modern change that leads to volatility) and this method is dependent on good historical data
Describe immunization
- a means of protecting a bond portfolio from interest rate risk
- essentially, purchasing zero coupon bonds (ie. T bills) tha are due to reach maturity at the time of any cash payout will totally immunize a portfolio against interest rate changes (this is known as a dedication strategy)
Describe matching duration
- durations of loans and deposits are matched to eliminate the gap that causes spreads to narrow and widen
- if the portfolios of assets and liabilities have equal durations then both portfolios will change in value equally and the financial institution’s net position is immunized
Describe target date immunization
- used for the pension industry where payout and maturity need to match
- to be successful interim interest payments are reinvested at the floating rate and at the same rate acting on the bond
Describe contingent immunization
- compromise between active and passive mgmt
- manager follows an active strategy until a trigger point (point where the portfolio’s value reaches the level at which a zero-coupon bond will mature to the target amount)
Describe a rate anticipation swap
- funds are moved from one end of the yield curve to the other
- if IRs are expected to fall, locking in higher rates for a longer period will be profitable
Describe horizon analysis
- analyst chooses a horizon over which the IR change is expected to evolve and at the end of which a new yield curve is predicted
- swapping two bonds for that period entails a difference in price for the two bonds at the end of the horizon
- if no change in the level of interest rates is expected, investors can ride the yield curve
What is the motivation behind a bond swap?
- potentially profit from the correct analysis of the proper value of the yield spread between the two fixed income securities
- the PM then structures and executes the trade or swap to capture this assumed market opportunity
At what point in time will the fixed income swap be reversed?
if either of the following occurs:
- the yield spread for the swap has moved in a favourable direction and has reached the PMs target spread, wherein they decide to reverse the trade and realize the profit
- the yield spread has not moved in a favourable direction and the PM decides to reverse the trade the take the loss
Reversing a fixed income swap involves what two steps?
- selling the FI security that was purchased at the initiation of the swap
- purchasing the fixed income security that was sold at the initiation of the swap
What is a box trade?
- involves the simultaneous execution of a pair of related fixed income security swaps
- they are related in that the pair of swaps involves the securities of the same two bond issuers
- it is called a box trade because the pair of bond swaps is commonly depicted as a box on a yield curve diagram
