US Stock Database provides a unique research source characterized by its unmatched breadth, depth, and completeness. It includes CRSP’s unique permanent identifiers allowing for clean and accurate backtesting, time-series and event studies, measurement of performance, accurate benchmarking, and securities analysis.

The CRSP US Stock Database contains end-of-day and month-end prices on all listed NYSE, Amex, and NASDAQ common stocks along with basic market indices, and includes the most comprehensive distribution information available, with the most accurate total return calculations.

Unique Historical Indices Databases serve as benchmarks for the investment community, and as a foundation for academic research. Created according to clear, unbiased and systematic processes, these indexes undergo rigorous procedures to promote data accuracy, timeliness and consistency. Each CRSP index is offered as a series that contains decile subsets for market analysis.

Mutual Funds: As the provider of the only complete database of both active and inactive mutual funds, CRSP leads the way in mutual fund research. The CRSP Survivor-Bias-Free US Mutual Fund Database serves as a foundation for research in and benchmarking for this asset class.

Created according to clear, unbiased and systematic processes, this database undergoes rigorous procedures employed to promote data accuracy, timeliness and consistency.

The CRSP Survivor-Bias-Free US Mutual Fund Database was initially developed by Mark M. Carhart of Goldman Sachs Asset Management for his 1995 dissertation (Chicago GSB) entitled, “Survivor Bias and Persistence in Mutual Fund Performance”, to fill a need for lacking survivor-bias-free data coverage.
