This module is used to create custom or blended benchmarks. For example, a blend can be made that contains 40% S&P 500, 50% FTSE and 10% Cash + 150 Bps. The blended benchmarks can be kept at the security-level for use with processes such as Performance Attribution, or aggregated into a single return stream for Compositing or Ex-Post Performance Analysis. It also allows for definition of dynamic weights for each component of the blend in cases where the blend definition rebalances to the asset class weight of certain funds.
