London Stock Exchange

Investor Monthly Manual 1869-1929

The Investors Monthly Manual (IMM), a record of The London Exchange, exists in hard copy for the period from 1871 to 1930, the peak of the colonial era. The London market was the most active market in the world at this time, trading not only domestic securities, but sovereign debt from all over the world as well as the equity and debt of foreign companies. The IMM records prices, dividends and capitalization, as well as other potentially useful information. The articles in the IMM detail issues of current interest to investors over the 70-year period.

The ICF  received a grant from a generous donor to transform this data into an electronic database that can be downloaded, manipulated and analyzed by scholars. The scanned Issues of the IMM are now available for download. One can also download a specific series or the entire database of the IMM annual data from our website.

Professors William Goetzmann and K. Geert Rouwenhorst welcome scholars who have already input or used some of this data to share their information through this site as well. We also welcome information about pertinent references pertaining to the database.
