History of Standard and Poor’s
The origin of Standard and Poor’s began in 1860. Henry Varnum Poor published a book called “History of Railroads and Canals in the United States.” The book provided a comprehensive coverage of the operational and financial state of railroad companies in the U.S. In 1868, Henry Varnum Poor and Henry William Poor created “H.V and H.W. Poor Co.,” which published two guidebooks that were updated annually.
The Standard Statistics Company was established in 1906, providing financial information regarding non-railroad companies. The Standard Statistics Company published its first stock market indicator in 1923, based on 233 companies.
Standard & Poor’s came into being in 1941 when Poor’s Publishing and the Standard Statistics Bureau merged. It increased the number of companies on the basis of which the stock index was computed to 416.
Later in 1966, The McGraw Companies acquired Standard & Poor’s Corporation, now known as S&P Global, after it rebranded in 2016.
