London Stock Exchange

There's no trouble in this river city, not for the London Stock Exchange (LSE). As Europe's largest stock exchange (and one of the oldest), the LSE lists some 3,600 depository receipts, Eurobonds, and company shares. The LSE includes the main market, the Professional Securities Market (or PSM, listed debt securities), and the Alternative Investment Market (or AIM, which lists new and growing companies). The LSE is also a leader in international IPOs. Its 2007 merger with Borsa Italiana gave the exchange additional clearing and settlement operations and is part of its international expansion strategy that includes a cooperative agreement with the Tokyo Stock Exchange
