Views (Risk and Correlation)

The WPA allows the user to input custom views for expected risk and correlations.

The users may enter up to five different sets of views in the grid. To select a set of expected risk and correlation (covariance) model for analysis, click on the column heading to highlight the column.

The user will be able to initialize a custom view by copying from the historical full-sample estimates.

When specifying views for risk, it is also essential to carefully consider the specification of correlation coefficients. If a correlation matrix is not positive semi-definite, WPA can either correct to the nearest positive semi-definite matrix or re-initialize the respective view estimates to the historical correlation matrix.
