London Stock Exchange

Investor Monthly Manual 1869-1929

London Stock Exchange

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
