Managed Security Master

Qudol links multiple records, time periods, and vendor asset identifiers as a single security, and algorithmically assigns it a unique identifier (QUID). QUID manages Issuer, Instrument, and Listing and provides continuity after Corporate Actions. It supports any asset class—Public Equity, Fixed Income, Credit Strategies—even Real Assets and Private Equity.

You share your raw data—vendor asset identifiers, market symbols (public or internal) etc.—with us. Qudol Security Master Algorithm analyses your content, assigns linking identifiers and your custom, historical QUID-to-vendor-asset mapping information is shared with your Snowflake account in the following two tables.

1. tSecurity: List of assets from all vendors and their basic attributes (time-series). Typical fields include AssetCode, FromDate, ToDate, AssetName, AssetType, IssueCurrency etc.

2. tSecurityMap: Asset to market symbols map (cross-tab, time-series) including QUID. Typical fields include AssetCode, FromDate, ToDate, QUID, VendorID, CUSIP, SEDOL, ISIN and other proprietary (or licensed) symbology from the data your shared with us.

With these tables from Qudol Security Master, you can relate asset identifiers from multiple vendors accurately at any point in time. All data, history, and logic are linked through the QUID, allowing for powerful, historical analytics.
