Traditional Fixed Income Management Styles Need To Be Augmented
Macro Shop– Interest rates and curves are not as trendy and predictable– Shocks are frequent and can ruin several years of performance– Bets need to become tilts: calculated, diversified, mild, and
gradual
Credit Shop– Credit markets shocks are becoming unavoidable– Concentrated credit portfolios have unacceptable risks– Credit risk need to be evaluated in the portfolio context
Mortgage Shop– True arbitrage opportunities are few and far in between– No strategic value in writing options– Bets need to be explicit and become tilts

QUANDAMENTALTM Process
Ensure value is added consistently over time using disciplined processes
– Formulation of consistent winning strategies
– Product templates and maps• sources of alpha and tracking error
• Probabilistic evaluation of tactical and strategic portfolio biases
Facilitate creative decision making process – Blend creative fundamental thinking with quantitative methods
– Disciplined forecasting
– Consistent cross sector relative value Risk adjusted
– Portfolio optimization and construction
– Risk management
4
Common Themes
Full integration of risk management and portfolio management processes
Common process for all products and portfolios– Mass customization?
• Core, Core Plus, Intermediate, Long, and Structured Products
Both Top-down and Bottom-up
5
Role of Quants in the Organization
Product definition and design
Process definition and tools• Design and conceptualize tools to be implemented by IT
Add value by blending smart ideas and quantitative concepts
Challenges:
Cultural
Finding people with both quantitative and fundamental strength

Cross-Sector Relative Value Process
SectorInformation
- Fundamental- Technical- Valuation
Bond Policy- Optimized curve and sector
exposures- MAC, IG Corp, HYLD and EMG
sector allocation versus normal- Portfolio maps
Bond Policy Curve and Swap Spread Forecast- Quantitative tools- Fundamental judgment- Risk/reward reconciliation
Risk-Controlled Sector Optimization
Bottoms-Up Analyst/Sector Evaluation
- Factor Sheets- Analyst rating- Spread forecast
Macro Environment- Factors affecting U.S. economic
growth (Economic, Monetary, International, Political, Asset Markets)
- Economic scenarios and probabilities (GDP, Inflation, FF)
Quantitative Cross-Sector Relative Value Tools
- Relative Statistics- Volatilities- Relative Z scores and ranges- Cross plots- Market snapshot- Internal and LehmanLive
Sector Teams- Optimal implementation plan- Intra-sector relative added-value- Security selection- Monitoring and re-evaluation- Bond policy feedback

Product Definition
Product Templates - Long Term– Tactical
– Strategic
Product Maps– Detailed targets per sector/credit/duration bucket
– Daily monitoring of absolute and relative Exposures• Portfolio vs. Target
• Portfolio vs. Benchmark
Transparency of Risk/Reward Goals Throughout Organization
9
Quantitative Models
Quantitative models are used to support key decisions and are an integral part of the overall process
– Interest and Curve Models• Interest rate forecast
• Curve forecast
• Treasury hump (20 to 25 year part of the curve)
– Swap Spread
– Value-at-Risk and Risk-Constrained Optimization
– Credit driven scenario models for structured products
– Prepayment and credit scoring for ABS securities
– Specific and portfolio credit risk models
10
Risk-Constrained Optimization Model
Proprietary model creates robust framework for comparing risk and reward across sectors
Model Objectives: Within the context of forecast scenarios, define maximum-return portfolio subject to acceptable risk levels.
– Inputs:• Expected yield/spread changes
• Historical pricing data for sectors
• Current benchmark structure and portfolio holdings
