10.3 Fixed Income Strategies

Managing fixed income portfolios requires understanding various strategies for different client objectives, market conditions, and risk tolerances.

Bond Portfolio Structures

Laddering Strategy

Definition: Building a portfolio of bonds with staggered, equally-spaced maturity dates.

Example: 10-Year Ladder

- Year 1: $10,000, Maturity Year 1

- Year 2: $10,000, Maturity Year 2

- Year 3: $10,000, Maturity Year 3

- Continuing in the same pattern through Year 10: $10,000, Maturity Year 10

When bonds mature, the principal is reinvested in new 10-year bonds, maintaining the ladder.

Benefits of Laddering:

- Reduces interest rate risk: Not locked into single rate

- Provides liquidity: Regular maturities provide cash flow

- Smooths rate changes: Average into new rates over time

- Simple to implement: Straightforward structure

- Flexibility: Can use maturing bonds for expenses or reinvest

Best For: Conservative investors seeking steady income with reduced interest rate risk.

Barbell Strategy

Definition: Concentrating holdings in short-term AND long-term bonds with little or no intermediate-term bonds.

Example Structure:

- 50%, 1-3 years (short), Purpose: Liquidity, reinvestment flexibility

- 0%, 4-7 years (intermediate), Purpose: Avoided

- 50%, 8-10+ years (long), Purpose: Higher yields

Benefits:

- Short-term provides liquidity and reinvestment opportunities

- Long-term locks in higher yields

- Can adjust weights based on rate outlook

- More tactical than laddering

Best For: Investors willing to take a tactical approach and adjust based on interest rate expectations.

Bullet Strategy

Definition: Purchasing multiple bonds that all mature at approximately the same time.

Example: All bonds mature in Year 7

- Purchase Date Year 1, Maturity Year 7, Years to Maturity at Purchase: 6 years

- Purchase Date Year 2, Maturity Year 7, Years to Maturity at Purchase: 5 years

- Purchase Date Year 3, Maturity Year 7, Years to Maturity at Purchase: 4 years

- Purchase Date Year 4, Maturity Year 7, Years to Maturity at Purchase: 3 years

Benefits:

- Matches a specific future liability (college, retirement)

- Reduces interest rate risk through staggered purchases

- Maximizes cash available at target date

Best For: Investors with a specific future cash need (liability matching).

Strategy Comparison

- Maturities: Ladder: Evenly spread; Barbell: Short and long only; Bullet: Concentrated at one date

- Purpose: Ladder: Steady income, flexibility; Barbell: Tactical positioning; Bullet: Match future liability

- Rate Risk: Ladder: Moderate; Barbell: Varies by weights; Bullet: Reduced by staggered purchases

- Complexity: Ladder: Low; Barbell: Moderate; Bullet: Moderate

- Liquidity: Ladder: High (regular maturities); Barbell: Moderate; Bullet: Low until target date

Duration Management

Understanding Duration

Duration measures a bond's sensitivity to interest rate changes. It represents the approximate percentage price change for a 1% change in interest rates.

Price Change approximately = -Duration x Interest Rate Change

- Duration 5 years, Interest Rate Change +1%, Approximate Price Change: -5 x 1% = -5%

- Duration 5 years, Interest Rate Change -1%, Approximate Price Change: -5 x (-1%) = +5%

- Duration 10 years, Interest Rate Change +1%, Approximate Price Change: -10 x 1% = -10%

- Duration 10 years, Interest Rate Change -1%, Approximate Price Change: -10 x (-1%) = +10%

Key Relationships:

- Longer maturity leads to Higher duration

- Lower coupon leads to Higher duration

- Higher duration leads to More interest rate sensitivity

Duration Strategies

If Expecting Rates to RISE:

- Shorten duration: Reduces price decline when rates rise

- Buy shorter-term bonds: Less sensitive to rate changes

- Sell longer-term bonds: Avoid largest price declines

If Expecting Rates to FALL:

- Extend duration: Maximizes price appreciation

- Buy longer-term bonds: More sensitive to rate changes

- Sell shorter-term bonds: Capture more upside

Duration Matching (Immunization)

Concept: Match portfolio duration to the client's investment horizon.

If a client needs money in 5 years:

- Set portfolio duration to 5 years

- As time passes, duration naturally shortens

- Rebalance to maintain target duration

Result: Interest rate changes have minimal impact on meeting the liability.

Credit Strategies

Credit Quality Spectrum

- AAA to A: Investment Grade (High), Lower yield, very low default risk

- BBB: Investment Grade (Low), Moderate yield, low default risk

- BB to B: High Yield (Speculative), Higher yield, moderate default risk

- CCC and below: Distressed, Highest yield, high default risk

Credit Spread Strategies

Credit Spread = Corporate Bond Yield - Treasury Yield

- Expansion: Spreads Narrow (low risk perception), Strategy: Reduce credit exposure

- Recession: Spreads Wide (high risk perception), Strategy: Increase credit exposure (buy cheap)

Municipal Bond Strategies

Tax-Equivalent Yield

For high-bracket investors, municipal bonds may offer better after-tax returns:

Tax-Equivalent Yield = Municipal Bond Yield / (1 - Tax Bracket)

Example: 4% muni yield, 37% tax bracket

Step 1: Calculate the after-tax factor: 1 - 0.37 = 0.63

Step 2: Divide muni yield by after-tax factor: 4% / 0.63 = 6.35%

Result: A taxable bond would need to yield 6.35% to match the 4% muni after taxes.

In Practice

Strategy selection depends on:

- Interest rate outlook

- Income needs and timing

- Risk tolerance

- Tax situation

- Time horizon

On the Exam

Series 65 frequently tests:

- Understanding the three structures: ladder, barbell, bullet

- Knowing that duration measures interest rate sensitivity

- If rates expected to rise, shorten duration; if fall, extend duration

- Tax-equivalent yield calculation for municipal bonds

Key Takeaways

1. Laddering spreads maturities evenly - provides liquidity and reduces rate risk

2. Barbell concentrates in short AND long maturities - tactical approach

3. Bullet targets a single maturity date - matches future liabilities

4. Duration measures interest rate sensitivity

5. Rising rate expectations lead to shorten duration; falling rates lead to extend duration

6. Higher tax brackets benefit more from municipal bonds
