Northfield's double hybrid methodology combines the advantages of both time-series and cross-sectional regressions for different types of defined factors, and the addition of statistical factors to capture residual systematic common factor risk ensures that stock specific risk really is due to stock specific effects, and is uncorrelated with other assets. Time-series regressions using Bayesian priors are used to determine the sensitivity of all stocks to their Currency, Market and Industry factors. We then use statistical significance tests to see whether stocks have additional exposures to other Market and Industry factors. The XRD betas capture the underlying economic exposures of each individual security, so the risk model recognizes that there will be high beta and low beta stocks for all factors. The portfolio betas to these factors enable fund managers to distinguish between portfolio weights and portfolio exposures, which can, of course, be very different. The Currency factors capture the foreign currency exposure of foreign stocks. This feature is particularly helpful to investors seeking to hedge their foreign currency exposures, as the portfolio betas to the Currency factors represent the appropriate hedging ratios for these currencies. Using time series regressions to estimate the Currency, Market and Industry betas has the advantage that some of the estimation error will diversify away when portfolio betas are calculated. Our proprietary XRD technology also helps to minimize sample specific estimation errors, with the result that the Northfield XRD Risk Models give more accurate portfolio risk forecasts. Fund managers can use this risk model to estimate the exposure of their portfolios to a very wide range of Commodities and Macro-Economic variables, spanning the G20 countries and more. The overall risk model universe currently includes equities, ADRs, GDRs, ETFs and indices. The risk model is updated every Thursday morning, using four historic look-back periods of eighty 4-weekly returns (just over 6 years). This ensures that all the security returns are the same length (unlike calendar months), and also avoids the biases that may arise from concentrating the impact of end-of-month, end-of-quarter and end-of-year effects. All XRD models are available in a wide range of base currencies.

The XRD Equity Risk Models
Each of the XRD risk models are automatically updated weekly within our Portfolio Risk Management system, PRISM. The risk model is also available weekly in Flat File Format (Pipe Delimited text file) 2004 or 2005 At least the top 98% of each market by capitalization The model is based on eighty exponentially time-weighted 4-weekly returns Time-weighting exponential coefficient = 0.985 Half-life = 46.9 * 4 weeks = 3.6 years Half-weight = 28.6 * 4 weeks = 2.2 years Test for inclusion 97.5% Test for exclusion 92.5% Winsorise the highest and lowest 2% of betas for each time series factor to the next nearest beta to that factor within each of the 4 SRD models. We first build 4 Single Reference Day (SRD) risk models using 4 sets of historic returns offset by 1 week each. The 4 SRD models are then averaged to produce the XRD risk model. This technique significantly reduces sample-specific estimation errors, and gives better portfolio risk forecasts. These are weighted by current market capitalization with a maximum constituent weight of 30%. The Large Market factor is built from the top 80% stocks by market capitalization, there is a (Mid Cap) gap of 8% to 10%, and the Small Market factor is built from the next 8% to 10% of stocks. These are weighted by current market capitalization with a maximum constituent weight of 30%. Industry priors are based on the Global Industry Classification Standard (GICS). These are constructed by running Principal Components Analysis on the correlation matrix formed from the residual returns of all full history stocks.

*This table shows the Currency Factors in each model (and together, the Global model) from the perspective of a US Dollar based investor. All XRD Models are available in any of the above currencies. In alternative base currency versions, the US Dollar would then become a Currency factor in the model, replacing the new base currency.
