Reference and historical data
The London Stock Exchange’s UnaVista Data Solutions
incorporates a wide range of reference data products. Our reference and historical data products are powered with data collected directly from source and set the benchmark for completeness, accuracy, and timeliness.
Reference data is widely seen as the key building block in effective data management and straight through processing (STP). The London Stock Exchange's reference data products are essential, not only for the maintenance of London trading data, but through the SEDOL Masterfile's global, multi-asset database, for security masterfile maintenance worldwide.
Our reference data services are listed below.
SEDOL Masterfile - uniquely identifying the world’s reference data
SEDOL Masterfile (SMF) is the Exchange’s official code to identify global securities. It provides reference data on millions of global multi-asset securities, each uniquely identified at the market level by our universal SEDOL code. By collecting global reference data directly from source, SMF is designed to lower costs, streamline post-trade processing and settlement, and minimise the risk of cross-border trade failures.
