Features & benefits
Portfolio analysis and risk management

Market tested models *
Market tested models
Use our sophisticated models for trade and portfolio applications. Term structure models, mortgage and asset-backed prepayment models, and default and loss severity models serve as the backbone for analysing option-adjusted spread, effective duration, convexity, and a wide range of other value and risk measures. Models are calibrated across a variety of security types.
Financial models
Used by broker-dealers, institutional investors, government agencies, consultants and educational institutions.
- Models calculate consistent risk and return measures for all security types.
- Sophisticated architecture allows users to quickly execute computationally intensive calculations.
- Flexible settings enable users to prepare customised analyses
Yield curve models
- Treasury model curve
- LIBOR swap curve
- Corporate credit curves
- Government (global) curves
- Swap (major currencies) curves
- On-the-run
- Fitted live and historical

Yield curve models *
Yield Book provides government yield and swap curves for Euro participating and non-participating countries. For US dollar securities, users have the choice of using an interpolated on-the-run curve or a proprietary off-the-run fitted yield curve, called the treasury model curve. This curve, pictured in yellow in the graph, provides relative value analysis for treasury securities. The OAS to the treasury model curve indicates a bond's relative value. When doing pricing calculations, users can select whether their spread output is computed relative to a government, a swap, or a corporate credit curve.
Prepayment models
- Mortgage prepay model
- ABS issuer specific prepayment models
- Japanese GHLC model
- Dutch model
- CMBS default model

Prepayment models *
Prepayment projections are key to the analysis and evaluation of all mortgage backed securities. The mortgage prepayment model incorporation in Yield Book allows users the choice of running the model "as is" or customising the model by modifying various "dials" for prepayment factors, including the effect of housing turnover or refinancing. The sample page illustrates the effect of modifying the refinancing threshold on prepayments.
Term structure of volatility models
- Market volatilities
- Historical volatility

Term structure of volatility models *
Yield Book's interest rate models are calibrated using a term structure of volatility. This allows a more accurate evaluation of securities with embedded options (e.g. calls, puts, sinking funds, caps, floors, prepayments, etc.). The sample page below shows Yield Book's curve analysis page, which allows users to display and analyse current and historical yield curves. The graph shows the projected dispersion (the expected path within an 80% probability band) of the 3-month swap rates derived from the term structure of volatility model.
Futures delivery option model

Futures delivery option model *
The futures delivery option model calculates the futures price, the value of the option, and the price sensitivities (DV01 and CV01). The delivery option model analyses all of the underlying deliverable bonds, including any special financing rates. The model DV01 is used for hedging and risk analysis. The model futures price can be compared to the marked price to determine relative value (trading the basis).
Trade and portfolio
To assist Portfolio Managers in analysing their trade ideas and portfolio strategies, Yield Book is capable of addressing scenarios involving individual securities, multiple security types, or portfolios, and in one or more currencies. Yield Book also provides the ability to easily customise reports.
Portfolio profiles:
Yield Book provides government yield and swap curves for Euro participating and non-participating countries. For US dollar securities, users have the choice of using an interpolated on-the-run curve or a proprietary off-the-run fitted yield curve, called the treasury model curve. This curve, pictured in yellow in the graph, provides relative value analysis for treasury securities. The OAS to the treasury model curve indicates a bond's relative value. When doing pricing calculations, users can select whether their spread output is computed relative to a government, a swap, or a corporate credit curve.

Portfolio profiles *
Cash flow analysis:
Generate issue specific and portfolio scenario dependent cashflows. Compare the cashflows to scenario dependent liabilities or to the cashflows of a benchmark portfolio. The scenarios can be parallel shifts, reshapings, multiple yield curve shocks, and currency exchange rate projections. Yield Book utilises its financial models (term structure model, mortgage prepayment model, corporate option model, etc.) to project each security's cashflow for each interest rate scenario. The sample graph displays the projected cashflows of XYZCO portfolio for a "bearish steepening" scenario.

Cash flow analysis *
Risk analysis:
Calculate a wide range of issue specific and portfolio risk measures including: effective duration, partial (key rate) durations, effective convexity, volatility duration, spread duration, current coupon spread duration, prepay duration, refi-prepay duration, and turnover-prepay duration. The sample report compares the partial durations of XYZPORT to the FTSE world broad investment-grade bond index within major industry groups.

Risk analysis *
Flexible reports:
In addition to the dozens of pre-defined reports, users can create their own customised report templates. The columns can be any combination of hundreds of Yield Book keywords, user defined keywords, or user defined functions. The rows can be individual securities or sectors averages.

Flexible reports *
Portfolio optimisation:
Yield Book incorporates a powerful yet user friendly optimiser for calculating optimised trade weightings and structured portfolios (index tracking portfolios, cash matched portfolios, etc.). The objective and constraints can be defined using any of hundreds of security measures including scenario returns, cash flows, yield measures, risk measures, etc.). In addition, upper and/or lower bounds can be defined on the issue, issuer, or sector level. The sample page shows the result of an projected optimisation to maximise the returns of XYZPORT relative to the BIGINDEX across seven reshaping scenarios.

Portfolio optimisation *
Scenario analysis:
Calculate projected issue specific and portfolio scenario rates of return (ROR). Compare the portfolio's scenario RORs to the RORs of the benchmark. The scenarios can be parallel shifts, reshapings, multiple yield curve shocks, and currency exchange rate projections. Yield Book utilises its financial models (term structure model, mortgage prepayment model, corporate option model, etc.) to project each security's cashflow for each interest rate scenario. The sample graph displays the RORs of XYZCO portfolio to the RORs of the BIGINDEX across seven reshaping scenarios.

Scenario analysis *
Return attribution:
Get a better understanding of the sources of return for individual securities, trades, and portfolios (including dynamic portfolios). Yield Book dissects total returns into treasury components (returns due to the yield curve; rolling yield, parallel shift, and reshaping) and spread advantage (returns in excess of the yield curve; spread, spread change, convexity advantage, reshaping advantage, volatility change, current coupon spread change, prepayment dif, etc). By comparing the portfolio's return components and sector weightings to a benchmark, Yield Book measures the issue selection and sector weighting effects.

Return attribution *
Tracking error:
Yield Book tracking error module conducts tracking error and risk decomposition analysis at the security, trade, portfolio, and portfolio versus benchmark level. The model employs a principal component approach to capture historical risk factor changes for 800+ global risk factors and a simulation-based methodology to project changes for these risk factors. The sample page on the right shows total ex-default return distributions for a portfolio versus benchmark analysis; distributions are shown at the portfolio, benchmark, and portfolio versus benchmark level.

Tracking error *
Batch scripts:
Automate Yield Book operations including portfolio uploads, pricing, scenario analysis, return attribution, report generation and downloads. Batch jobs can be set to run overnight on a daily, weekly, or monthly frequency, so that results are waiting for you the next day.

Batch scripts *
Quick report packages:
In addition to the dozens of pre-defined reports, users can create their own customised report templates. The columns can be any combination of hundreds of Yield Book keywords, user defined keywords, or user defined functions. The rows can be individual securities or sectors averages.
