AMEX's core business has shifted over the years from stocks to options and Exchange-traded funds, although it continues to trade small to mid-size stocks. An effort in the mid-1990s to initiate an Emerging Company Marketplace ended in failure, as the reduced listing standards (beyond the existing lenient AMEX standards) caused penny stock promoters to move their scams to a national exchange. In the mid 1990s the exchange was dogged by allegations of trading scandals, which were highlighted by BusinessWeek in 1999.[9] In 1998, the American Stock Exchange merged with the National Association of Securities Dealers (operators of NASDAQ) to create "The Nasdaq-Amex Market Group" where AMEX is an independent entity of the NASD parent company. After tension between the NASD and AMEX members, the latter group bought out the NASD and acquired control of the AMEX in 2004.Out of the three major American stock exchanges, the AMEX is known to have the most liberal policies concerning company listing, as most of its companies are generally smaller compared to the NYSE and NASDAQ. The Amex also specialises in the trading of ETFs, and hybrid/structured securities. The majority of U.S. listed ETFs are traded at the AMEX including the SPDR and most Powershares.
In 2006, the AMEX attempted to popularize an American implementation of the Canadian income trust model. Listed Equity Income Hybrid Securities, (more commonly known as Income Deposit Securities) listed on the AMEX are B & G Foods Holding Corp. (BGF), Centerplate, Inc. (CVP), Coinmach Service Corp. (DRY), and Otelco Inc. (OTT). Recently Coinmach Service Corp, has been attempting to restructure itself away from being an income trust.
As of 31 December 2007, the AMEX had 592 listed companies with a combined market capitalization of $258 billion.[10]
The AMEX also produces stock market indices; perhaps the most notable of these is an index of stocks of internet companies now known as the http://en.wikipedia.org/w/index.php?title=Inter@ctive_Week&action=edit&redlink=1 Internet Index. Recently, the AMEX has also developed a unique set of indices known as Intellidexes, which attempt to gain alpha by creating indices weighted on fundamental factors. The AMEX Composite, a value-weighted index of all stocks listed on the exchange, established a record monthly close of 2,069.16 points on November 30, 2006.
