3 What are the highlights of recent features?
Sovereign Correlation: Our research findings» Average correlation of sovereigns is higher than the average correlation of other asset classes» Large variations in correlation across countries not prudent to use one fixed correlation for all sovereigns
Using Sovereign Correlation to accurately capture the impact of sovereign risk on my portfolio Portfolio Characteristics:» Sovereign debts from 89 countries Case Study:» Use fixed RSQ (= 65%) vs. MA-provided Sovereign RSQs Portfolio Results ($MM) "Fixed" RSQs Sovereign RSQs MTM 68.04 69.10 Expected Spread 3.64 3.52 Expected Loss 0.24 0.25 Unexpected Loss 5.55 5.36 Capital 10.46 9.98 Sharpe Ratio 65.57% 65.65% Vasicek Ratio 34.81% 35.27% Brazil actually has higher risk contribution to the portfolio when accounting for sovereign correlation No impact on Spain s risk contribution Other countries (e.g. UK, Greece) have lower risk contribution than originally thought Sovereign Correlation reveals how much each country really contributes to the overall portfolio risk
Using RiskFrontier to optimize a deal Strategies to Reduce Risk / Increase Return: Strategy A A. Increase fees / reduce LGD Expected Spread Strategy C Names with higher Sharpe Ratio Strategy E Names with lower Sharpe Ratio Strategy B Initial Strategy D B. Reduce commitment C. Hedge w/ CDS D. Sell / Don t renew E. Redeploy budget for better investment Risk Contribution
Using Trade Optimization to improve the portfolio Portfolio Characteristics:» $2.5 billion» 450 U.S. and Canadian corporate bonds» Highly concentrated in oil exploration and construction Strategy:» Sell 5 bonds in highly concentrated industries, totaling = $27.7MM» Use RiskFrontier to decide how to invest the available capital based on a list of potential deals Portfolio Results ($ millions) Results: Before Trade Optimization After Trade Optimization MTM 1,636 1,630 Expected Loss 44 44 Unexpected Loss 96 95 Capital 161 155 Sharpe Ratio 91% 93% Vasicek Ratio 54% 57%» Buy 5 bonds in less concentrated industry (e.g. media) to optimize Sharpe Ratio» Optimally trading < 1% of portfolio reduced portfolio risk by 4% -1% -4% +2% +3% 18
Using Relative Risk to measure performance of your portfolio against a benchmark, index, or target portfolio Caisse Bond Portfolio:» Mix of Canadian and Crown Corporation, Provincial, Municipal, and Corporate sectors, and bond derivatives» Concentration in Quebec» Modified duration of 6 years Benchmark Portfolio:» DEX Universe Bond Index (12/31/10) Regular Analysis Relative Risk Analysis Caisse Bond Portfolio Absolute CVaR Relative CVaR Other Corporate, 13% Municipal, 1% Financial Corporate, 14% Federal Govt, 46% Regular Analysis Benchmark Portfolio Absolute CVaR Provincial Govt, 26% 19
Using Relative Risk: practical example Portfolio Market Value Portfolio Absolute CVaR Benchmark Absolute CVaR Relative CVaR Billion $ Million $ b.p. b.p. Million $ b.p. Bond Portfolio 40 950 238 230 350 88 Provincial mandate 12 300 250 270 100 83 Canada mandate 17 100 59 55 10 6 Corporate mandate 11 700 636 560 250 227» Compare Absolute Risks Portfolio Absolute CVaR vs. Benchmark Absolute CVaR» Compare Relative vs. Absolute Risks (Portfolio Absolute CVaR Benchmark Absolute CVaR) vs. Relative CVaR» Quantify diversification effect Absolute CVaR of combined portfolio vs. Sum of Absolute CVaR of each sub-portfolios 20
Using Relative Risk to identify contributors of risks and returns Top Absolute CVaR Contributors Risk Market Contribution Value Ratings QUEBEC PROV 15% 15.0% A+ HYDRO-QUEBEC 8% 7.0% A+ CANADA GOVT 5% 35.0% AAA PUBLIC INVESTMENT #1 4% 1.0% BBB COPORATE #1 3% 0.5% B- Top Relative CVaR Contributors Relative Market Value Ratings Risk Contribution COPORATE #1 20% 0.5% B- PUBLIC INVESTMENT #1 14% 0.7% BBB COPORATE #2 10% 0.4% CCC COPORATE #3 6% 0.3% B- COPORATE #4 5% 0.3% CCC» Risk vs. Return Contributors (in absolute vs. relative terms)» Market Value Contributors (in absolute vs. relative terms)» Sources of Risk Contribution (e.g. ratings) 21
