Global Financial Data has eliminated the exchange bias.
Other stock databases limit themselves to providing data from the national exchanges, ignoring thousands of local companies that investors in the past would have considered when making their investments. Just as analysts and researchers want to avoid the survivorship bias of ignoring companies that have delisted, researchers and analysts should also avoid the exchange bias of ignoring the thousands of companies that listed on the regional, but not the national exchanges.
Global Financial Data has added extensive price data from regional stock exchanges to its U.S. Stocks Database. GFD now has the most extensive historical data on regional US Stock Exchanges available anywhere in the world. We have combined numerous sources to provide continuous monthly data from all the major historical regional stock exchanges in the United States up to 1972 when the NASDAQ came into existence.
Data from the regional exchanges covers not only smaller, local companies that listed exclusively on a regional exchange, but also many companies that listed on a regional exchange as a first step before moving to the New York Stock Exchange or New York Curb/American Stock Exchange. Companies that listed on the regional exchanges included not only local manufacturing companies, but local banks, utilities, resource and transportation companies.
Monthly price data are now available in the US Stocks Database for the following exchanges:
Baltimore –1803-1862, 1878-1949. In 1949, the Baltimore Stock Exchange merged into the Philadelphia Stock Exchange and ceased to exist.
Boston—1789-1972. Boston was one of the premier stock exchanges up until World War I. Many New England manufacturing companies listed exclusively on the Boston SE.
Chicago—1889-1949. Chicago provided listings for many local companies which went on to list on the New York Stock Exchange and New York Curb and was one of the largest exchanges in the US before World War II. The Chicago SE merged with several other stock exchanges in 1949 to form the Midwest Stock Exchange.
