London Stock Exchange
The FTSE 100 Index (often called the "Footsie") is like the Dow Jones Industrial Average in the United States. FTSE stands for Financial Times Stock Exchange. The 100 most valuable companies listed are tracked. The value of a company is calculated by multiplying the share price of the company by the total number of shares they have issued. The index took the place of the FT30 in January 1984.
