Risk Factor [MAR10.9]
The risk-factors are identified by:
Key Field | Description |
---|---|
As-of Date | Timestamp (at close of business) for the data (T-1) |
Risk Factor Name | A unique identifier for the risk-factor (not including vertices, for Vega) |
Risk Class | “Equity” |
Risk Measure | “Delta”, “Vega”, or “Curvature” |
Option Maturity | The maturity of the option (Vega) |
For Delta, the risk-factors have the following properties:
Property Field | Description |
---|---|
Equity Name (Underlying) | Name of the equity or equity issuer (see interpretation note). |
Type | “Spot” or “Repo”. |
For Vega and Curvature, the risk-factor is the same as the underlying.
Implementation notes (Vectors of vertices):
- The Vega risk-factor name spans all maturities, so represents multiple [MAR10.9] risk-factors.
- In the input files (default file format), multiple vertices and sensitivities may either be provided on the same row or different rows.
- In the datastore, we use vectors to store the sensitivities for all tenors.
- In the cubes, we use analysis hierarchies to expand the vectors.
