CRSP/Compustat Merged Database - Linking CRSP and Compustat

Why CCM (CRSP/Compustat Merged Database)?

CRSP and Compustat have been the two most widely used database for research in finance and accounting research.  As a CRSP product CCM provides a link between CRSP stock data and Compustat fundamental data since two of them do not share common security and company identifiers, while TICKERs and CUSIPs can change over time.
