Agenda

1. Introduction: VaR & TE2. Recent trends in risk measurement

and attribution3. Measuring the risk of alternative

investments4. Ideas for combined risk analysis of

traditional long-only portfolios with alternative investments

slide 3

1. Relative VaR & Tracking Error

• Relative VaR measures the risk of under performing a

Benchmark Portfolio

• Extends beyond PV, Duration and Gamma matching

• Tracking Error is a Special Case of Relative VaR

» Confidence Level = 84.13%

» Annualized Measure = 252 Trading Days

• VaR analysis brings standardization and flexibility to

risk analysis

Portfolio Notes:

1) Majority of Corporate Tracking Risk is due to Issuer-Specific Volatility.2) F/X Risk for International Bonds is mitigated by I/R correlations.

Portfolio Notes:

1) Retail, Oil&Gas, Computers, and Semiconductors add risk without anticipated reward.2) Phamaceuticals risk far exceeds anticipated reward.

3. Alternative Investments: Intelligence versus Information

• Position Transparency = Information» Managers providing investors with a list of positions

can be useless for today’s complex fund strategies.» Information ≠ Intelligence

• Analysis + Organization = Intelligence» Value is created when positions are independently

priced (standardized), linked to models and risk factors (data), analyzed, organized and aggregated

• Intelligence = Better Decisions» Better decisions are possible when well organized,

consistent reporting methods allow meaningful comparisons of valuations and risk results

slide 10

Risk Types

• Market Risk – potential loss due to market price volatility under normal and stressed conditions. Risk factors include equity time series, yield curves, volatilities, volatility surfaces, commodities, and currencies.

• Credit Risk – potential loss due to issuer specific risk. CreditGrades uses a structural Merton model to calculate issuer specific spread risk.

• Valuation Risk – potential loss due to hard to price, illiquid or mispriced securities.

4. Combined Risk Analysis

Options:1. Describe alternative investment

exposure as a beta to an index2. Construct a NAV series for a fund or

fund-of-fund3. Combine portfolio using sensitivities4. Describe alternative investment

exposure as a sensitivity instrument within the regular VaR framework

slide 15

Considering the Options

• No access to exposure level detail• Hedge Funds do not adhere to benchmarks• Portfolio churn and style drift may lessen the

relevancy of past returns• Standardized models and market data• Sensitivities can be added:

» Exposure to risk type» Exposure to scenario type» Exposure to risk factor

• Hedge fund exposures can be evaluated as a regular asset type with given sensitivities to standard risk factors

Summary

• Detailed analysis and attribution of risk is available for traditional long-only portfolios

• Alternative Investments pose challenging problems but can be solved with:» Transparency» Standardization

• Including Alternative Investments as an asset class can be done with sensitivities to:» Standard risk factors» Standard stress scenarios
