Data source type
Time period coverage
Unlike other kinds of databases, Amadeus is not a historical database and strives for recent information. Financial data for companies within Amadeus is retained for a rolling period of 8 years. When a new year of data is added, the oldest year is dropped, meaning only the most recent data for each company is available. Only the most recent ownership data for each company is available.
There are some limitations on the types of data available. Banks and insurance companies are excluded from Amadeus. These types of companies are part of the Bankscope and Isis datasets respectively, for which Aalto currently does not have a subscription. Additionally, stock data is available for publicly traded companies, all of which fall into the Very Large category, but it makes up a very small percentage of the entire database.
For a list of countries represented in the Amadeus database and more details, see the overview provided by WRDS, link is provided under "Supporting materials" below. Note that you need to be logged into the platform to access the data description.
The Amadeus subscription is financed by the Department of Finance at Aalto University School of Business.
