Whats LSE?

The London Stock Exchange, abbreviated LSE, is currently the third-largest stock exchange in the world by market capitalization. In December 2014, the market capitalization of the LSE was the equivalent of 6.06 trillion USD. The only two exchanges larger than LSE by this measurement is the New York Stock Exchange and NASDAQ. This means that LSE is the largest exchange in Europe, ahead of both Euronext and Deutsche Börse.

The London Stock Exchange is located in the City of London, England, United Kingdom. You will find the exchange building in Paternoster Square, near the famous St Paul’s Cathedral.

The currency used for trading at the LSE is the Pound Sterling (GBP).
