WRDS is a web-based research platform offering access to a wide variety of business and finance related datasets. Datasets can be queried and downloaded through a common interface. 

Accessing particular third-party datasets through WRDS typically requires a separate Aalto-wide subscription with these third-party data vendors. Therefore, not all datasets on the platform will be available to Aalto users. 

The most important datasets available through WRDS are CRSP and Compustat, containing market data and fundamental data on publicly listed U.S. companies. See "Related data sources" below for a list of subscribed datasets available through WRDS. WRDS offers some datasets that are available without additional subscriptions and mainly consist of publicly available data. These include: 

  • Federal Reserve Board Foreign Exchange Rates
  • Interest Rates
  • State Composite Indexes 
  • FINRA TRACE bond transactions 
  • Fama-French portfolios 
  • factors EU Short Sales
