Euronext Amsterdam (EURONEXTAMS), formerly known as the Amsterdam Stock Exchange, is the sole stock exchange in the Netherlands. It was founded in 1602 and it is considered to be the oldest in the world. The exchange is headquartered in Amsterdam, the country's capital and most populous municipality, which is also a key international financial hub. It merged in the year 2000 with the Brussels Stock Exchange and Paris Bourse to form the pan-European exchange Euronext, which is currently the largest exchange in continental Europe. EURONEXTAMS is supervised by the Netherlands Authority for the Financial Markets (AFM) and is subject to both E.U. and Dutch regulations. All transactions are processed through a trading system called the Universal Trading Platform (UTP), which will be replaced by a new multi-market platform called Optiq. It lists 169 companies with a total market cap of €937 billion and also houses bonds and ETFs.
Among the listings are well-known and actively traded companies such as AkzoNobel, ING group, Philips, Royal Dutch Shell and Unilever. The main stock index is the AEX index, a capitalization-weighted index composed of the 25 largest listed companies, which is widely recognized as the benchmark index for the Dutch stock market. Related indices are the AMX index, which tracks the performance of 25 mid-cap stocks and the AEX GR, a gross total return index that tracks the capital gains of the AEX companies over time. All constituents are screened for eligibility and reviewed annually but there is room for quarterly fast entries or replacements. EURONEXTAMS operates several indices that reflect the performance of national sectors and industries. Dutch stocks are also included in various European indices such as the Euronext 100 index, which tracks the performance of the largest and most liquid European stocks.
