Using a widely recognized multiple-factor risk model developed at BARRA, Grinold and pred is predicted volatility from the risk model. component to model. In 1979 BARRA expanded into the fixed income area with the release of our bond valuation and risk models. For example: if we estimate the covariance matrix by using 60 trading days and 30 stocks, then the predicted volatility from the risk model is half of the true risk. Alternatively, power your central distribution risk analysis with a linear-based model that focuses on benchmark relative analysis and risk hot spots, including a duration times spread approach to corporate bond risk.
