Incremental

Description

Naming pattern: Measures with “Incremental” behavior follow the name pattern:Main Measure Name Incremental.

The Incremental measures evaluate the impact of a trade or a group of trades (‘current scope’) on the result at a selected ReferenceLevel, by comparing it with a computation as if the considered trade or aggregate of trades were hypothetically removed.

 

$M^{incremental}(\text{scope})=M(\text{portfolio}) - M(\text{portfolio excl scope})$

Example

In the following example, the IMCC measure is showing the impact of individual desks on the firm-level IMCC number.

Incremental IMCC example

To validate the incremental measure for desk “Bonds”, let’s compute firm-level IMCC with a filter excluding the desk:

Incremental IMCC-validation

From the screenshot above, we can see that IMCC is approximately 17 mio higher (109.7 - 92.6) if the “Bonds” desk positions were closed-out.
