The EDSC offers three databases to get stock data: Datastream, CRSP and Bloomberg. Apart from the way to get data, the five most important differences are:
- Access: Getting data from Datastream is only possible at the Datateam pc’s in the Y03-17. Bloomberg terminals are available in Y03-18. CRSP is accessible via from home.
- Geographical coverage: CRSP only contains American stocks. Datastream and Bloomberg offer stock prices from Europe, America, Asia, Oceania and Africa.
- Historic: CRSP has data started from 1925. Datastream contains stock prices from 1973 onwards. Bloomberg from the beginning of the 80’s.
- Identifiers: to get data from financial databases like CRSP and Datastream identifiers are needed, these are codes identifying e.g. a company, stock or bond. In Datastream one can use ISIN-, SEDOL- or DS-codes, in CRSP you need the CUSIP (8 digits) or Ticker symbol to retrieve the data.
- Update: CRSP is being updated once a year, while in Datastream and Bloomberg the stock prices up til yesterday can be found.
