CRSP Reaches 90-Year Milestone

As of this year, the CRSP stock database spans 90 years of data across 15 business cycles. No other data provider can match the breadth, depth, and accuracy of CRSP historical data. Following is a timeline that provides a visual representation of this history, a brief explanation of why 1926 was the chosen date of initiation, and informational charts. In the sidebar are illustrative interactive data reports and academic resources for research.


CRSP Timeline

  • December 31, 1925

    In 1977, the original January 30, 1926, data file was updated in order to make this the initial date

  • January 30, 1926

    The starting point for the original CRSP project data collection. By starting with 1926, the initial study included 35 years of data, including two complete years preceding the 1928-1929 bull market.

  • February 16, 1926

    The Consolidated Stock Exchange ceases trading. NYSE increases in volume and reputation compared to smaller reginal exchanges. This event dovetailed with Fisher and Lorie’s decision to start with 1926 for NYSE listed stocks.

  • 1930

    Primary source material prior to this year is often incomplete or inaccurate. One of the reasons the initial database development project was extended from 6 months to a 3-1/2 year project was due to the difficulty of sourcing and checking early market data. The tedious nature of data validation is discussed in early speeches by Fisher and Lorie.

  • 1932

    U.S. Stocks are down -84%

  • 1946

    The U.S. Stocks are +783% total return

Why was 1926 significant?  

In early 1960, Chicago Booth Professors Lawrence Fisher and James Lorie were debating a logical starting point for the data collection that would be the inception of CRSP. They ultimately decided that the file needed to start at least one full business cycle before the 1929 stock market crash. By starting with January 30, 1926, the initial study included 35 years of data, including two complete years preceding the 1928-1929 bull market. (In 1977, the file was updated in order to make the initial date of data December 31, 1925.) 

Another major consideration for the initial date of data was the availability of complete and reliable data sources. Primary source material prior to 1930 is often incomplete or inaccurate. Moreover, as of February 16, 1926, the Consolidated Stock Exchange ceased trading. Consolidated had been the chief rival to the NYSE for many years prior to its demise. This increased the distance, in terms of volume and reputation, between NYSE and the many smaller regional exchanges. 

Fisher and Lorie, in their book A Half Century of Returns on Stocks and Bonds, offer this perspective on the value of historical data: 

The reasons for covering as long a time period as we can with consistent methods should  be obvious at this time. Historical data show the kinds of human experience that have taken place, and, perhaps, their relative frequencies. But each period also has its own special features. To ignore all data from the 1920s, 1930s, and early 1940s in estimating the riskiness of investments in common stock—as many did in the late 1960s—now appears to be foolhardy. Older data could be ignored safely only if risk were much better understood.
