The transatlantic stock market operator NYSE Euronext launched on Thursday with the listing of shares in Eurotunnel a new London exchange to rival the huge London Stock Exchange (LSE). Eurotunnel, which operates the rail tunnel that links Britain and France, \"rang the opening bell in London this morning at 8:00 am to celebrate its admission to trading on the London market of NYSE Euronext,\" a statement said. Eurotunnel remains listed on the Paris stock exchange as well, but the company\'s LSE listing is to be cancelled on Friday. NYSE Euronext already operates equity markets in Paris, New York, Amsterdam, Brussels and Lisbon, and the creation of a market to compete with the huge LSE was first announced in July 2010.
