The American Stock Exchange
As an auction market, the AMEX conducts its business on a trading floor through brokers and specialists. Each security traded on the exchange is handled by a specialist whose job it is to bring buyers and sellers together, and ensure that a fair market price is obtained for both parties. It is also a specialist's job to ensure that a market remains liquid, by buying or selling from their own account if no one else will. Brokers move around the floor, bringing 'buy and sell' orders to the different specialists on behalf of their clients.
The American Stock Exchange options exchange is one of the largest in the world, with over 1,700 options traded on stocks, American Depository Receipts, indexes, exchange traded funds, and HOLDRS. In addition, the AMEX has an extensive market for exchange traded funds (ETFs) as they were the first to trade in this particular market. The AMEX has a listing of over 140 ETFs on general stock markets, industries and corporate bond indexes.
