CRSP/Compustat Merged(CCM)

CCM provides concurrent database access for CRSP and Compustat data.

Data are matched using the databases with CRSP Link® which tends to be more reliable than matches by CUSIPs alone, because CUSIPs may change over time. The databases each contain a historical link history that supports complex relationships.

CRSP Link maps CRSP's permanent, unique identifiers, PERMNO® (permanent issue identification number) and PERMCO® (permanent company identification number), with COMPUSTAT's permanent, unique company identifier, GVKEY.

Data may be retrieved using ts_print or cst_print, CRSP's report writer utilities or through Fortran or C programs.
