CRSP-COMPUSTAT Firms Data between 1963-2017

CRSP (Center for Research in Security Prices) provides comprehensive historical financial market data, including stock prices, returns, trading volume, delisting information, and market indices for U.S. securities, making it a widely used source for asset pricing and financial market research. COMPUSTAT, developed by S&P Global Market Intelligence, contains detailed firm-level financial statement data, such as balance sheet, income statement, cash flow, and fundamental company information, and is extensively used in accounting, corporate finance, and empirical business research.

The CRSP/Compustat Merged (CCM) database links firms in COMPUSTAT to their corresponding securities in CRSP through unique mapping identifiers (primarily GVKEY and PERMNO/PERMCO), enabling researchers to combine firm-level accounting data with stock market data for integrated empirical finance and accounting analyses.
