American Stock Exchange in the context of "Mutual organization"

The Financial District of Lower Manhattan, also known as FiDi, is a neighborhood located on the southern tip of Manhattan in New York City. It is bounded by the West Side Highway on the west, Chambers Street and City Hall Park on the north, Brooklyn Bridge on the northeast, the East River to the southeast, and South Ferry and the Battery on the south.

The City of New York was created in the modern-day Financial District in 1624, and the neighborhood roughly overlaps with the boundaries of the New Amsterdam settlement in the late 17th century. The district comprises the offices and headquarters of many of the city's major financial institutions, including the New York Stock Exchange and the Federal Reserve Bank of New York. Anchored on Wall Street in the Financial District, New York City has been called both the leading financial center and the most economically powerful city of the world, and the New York Stock Exchange is the world's largest stock exchange by total market capitalization. Several other major exchanges have or had headquarters in the Financial District, including the New York Mercantile Exchange, NASDAQ, the New York Board of Trade, and the former American Stock Exchange.

Hand signaling, also known as arb or arbing (short for arbitrage), is a system of hand signals used on financial trading floors to communicate buy and sell information in an open outcry trading environment. The system is used at financial exchanges such as the Chicago Mercantile Exchange (CME) and the American Stock Exchange (AMEX). The AMEX is the only US stock market to permit the transmission of buy and sell orders through hand signals as of 2003.

Traders usually flash the signals quickly across a room to make a sale or a purchase. Signals that occur with palms facing out and hands away from the body are an indication the gesturer wishes to sell. When traders face their palms in and hold their hands up, they are gesturing to buy.

A capitalization-weighted (or cap-weighted) index, also called a market-value-weighted index is a stock market index whose components are weighted according to the total market value of their outstanding shares. Every day an individual stock's price changes and thereby changes a stock index's value. The impact that individual stock's price change has on the index is proportional to the company's overall market value (the share price multiplied by the number of outstanding shares), in a capitalization-weighted index. In other types of indices, different ratios are used.

For example, the NYSE Amex Composite Index (XAX) is composed of all of the securities traded on the exchange including stocks and American depositary receipts (ADRs). The weighting of each component shifts with changes to each securities' price and the number of shares outstanding. The index moves in line with changes in price of the component.
