Five Steps in Investment Management
Setting investment objectives
Establishing Investment Policy
(in cash equivalent, equities, fixed-income, real estate)
Select a portfolio strategy
(active, structured, or indexing)
Select assets
Measuring and evaluating performance (ch25)
BUS424 (Ch 23&24) 3
Spectrum of Bond Portfolio Strategies
• Bond benchmark-based strategies• Pure index matching
• Enhanced indexing: matching primary risk factor
• Absolute Return Strategies
• Liability-driven Strategies
(page 469)
BUS424 (Ch 23&24) 4
Top-down vs. Bottom-up Portfolio Construction
In the top-down approach, a bond portfolio manager looks at the major macro drivers of bond return and obtain a view about these drivers in form of a macroeconomic forecast. Then portfolio managers decide on how much of the portfolio’s fund to allocate among different sectors and in cash.
The bottom-up approach focuses on the micro analysis of individual bond issues, sectors, and industries.
BUS424 (Ch 23&24) 5
Tracking Error
The standard deviation of the return of the portfolio relative to the return of the benchmark index.
(example on pages 505-508)
• Calculate monthly or weekly tracking error
• Annualize it
BUS424 (Ch 23&24) 6
Two Faces of Tracking ErrorBackward-looking (ex-post) tracking error:
tracking error calculated from observed active returns for a portfolio
Forward-looking (ex-ante) tracking error: tracking errors associated with bond market index based on multi-factor models – setting an appropriate benchmark
BUS424 (Ch 23&24) 7
Risk Factors
Systematic risk factors
• Term structure risk factors
• Non-term structure risk factors
Non-systematic risk factors
• Issuer specific
• Issue specific
BUS424 (Ch 23&24) 8
Active Portfolio Strategies
Interest-rate expectations strategies
Yield Curve Strategies
Yield Spread Strategies
Individual Security Selection Strategies
Strategies for Asset Allocation within Bond Sectors
BUS424 (Ch 23&24) 9
Interest-rate Expectations Strategies
Increase or decrease duration
increase duration when expected interest goes down
decrease duration when expected interest goes up
Approach: Rate anticipation swaps
Gambling incentive – make an interest bet to cover inferior performance relative to a benchmark index.
BUS424 (Ch 23&24) 10
Yield Curve Strategy
Seek to capitalize on expectations based on short-term movements in yields; make profit from the change of yield curve in the portfolio
Key: if your investment horizon is 1 year, what strategy you want to take, put all your money in 1-year bonds or 30-year bonds
Depending on the shape of yield curve, or say yield curve changes
BUS424 (Ch 23&24) 12
Strategies
• Bullet strategy (see page 477)• Barbell strategy• Ladder strategyBond portfolios under alternative strategies have the same durations –
page 477.
To see which strategy to implement, investors need look at the impact of the strategy on the total return of the portfolio
Exhibit 22-6 on page 482 compares the relative performance of a bullet portfolio and a barbell portfolio
• One factor driving the difference in portfolio performance is the difference in their convexity.
BUS424 (Ch 23&24) 13
Yield Spread Strategies
Involve positioning a portfolio to capitalize on expected changes in yield spreads between sectors of the bond market.
Swapping one bond for another when the manager believes that the prevailing yield spread between the two bonds in the market is out of line with their historical yield spread.
BUS424 (Ch 23&24) 14
Yield Spread Strategies
Credit spreads – depends on economic condition
Spreads between callable and noncallable bonds – depends on interest rate
Page 485
BUS424 (Ch 23&24) 15
Individual Security Selection Strategy
Identify mis-priced securities
(1) Its yield is higher than that of comparably rated issues
(2) Its yield is expected to decline because credit analysis indicates that its rating will improve
To implement this strategy: swap.
BUS424 (Ch 23&24) 16
Strategies for Asset Allocation with Bond Sectors
• Government/agencies• Corporates• Mortgage backed securities
• An example for guiding and assessing the allocation of funds among the credit sectors within the corporate bond sector. Page 487-489.
BUS424 (Ch 23&24) 17
Use of Leverage
A portfolio in which a manager has created leverage.
If return from investing the amount borrowed exceed cost of funding.
Leveraging trades will generate a return needed to make the investment attractive to traders.
BUS424 (Ch 23&24) 18
Create Leverage with Repo
Repurchase agreement: sale of a security with a commitment by the seller to buy the same security back from the purchaser at a specified price at a designated future date.
Repurchase price
Repurchase date
Repo rate
Overnight repo versus term repo
BUS424 (Ch 23&24) 19
Example
A dealer delivers (sells) $10 million of treasury security to a customer and buy it back in to the next day. Repo rate is 6.5%. (dealer is financing a long position) (page 541)
Dollar interest = (dollar amount borrowed)*(repo rate)*repo term/360
BUS424 (Ch 23&24) 20
Repo
Questions:
• What is amount borrowed by the dealer?
• What is the dollar interest
Jargons: (1) reversing out securities, (2) reversing in securities – page 492
BUS424 (Ch 23&24) 21
Indexing
Designing a portfolio so that its performance will match the performance of some bond index
Benefits and costs (page 509)• Low management fee and expenses• Straightforward and easy to evaluate• Basis risk between indexing and matching to
liabilities
BUS424 (Ch 23&24) 22
Factors Affecting Index Selection
Level of Risk Tolerance
Investor’s objective• Difference in variability
• Nonsymmetry in rising and falling markets
BUS424 (Ch 23&24) 23
Issues of an Indexed Portfolio
Tracking error: the discrepancy between the performance of the indexed portfolio and the index
The tradeoff between transaction costs and mismatching of the characteristics of the indexed portfolio and the index.
Logistical problems in implementing an indexing strategy
