The New York Stock Exchange (NYSE, nicknamed "The Big Board") is an American stock exchange located at 11 Wall Street, Lower Manhattan, New York City, New York. It is by far the world's largest stock exchange by market capitalization of its listed companies at US$30.1 trillion as of February 2018. The average daily trading value was approximately US$169 billion in 2013. The NYSE trading floor is located at 11 Wall Street and is composed of 21 rooms used for the facilitation of trading. A fifth trading room, located at 30 Broad Street, was closed in February 2007. The main building and the 11 Wall Street building were designated National Historic Landmarks in 1978.
In 1817 the stockbrokers of New York operating under the Buttonwood Agreement instituted new reforms and reorganized. After sending a delegation to Philadelphia to observe the organization of their board of brokers, restrictions on manipulative trading were adopted as well as formal organs of governance. After re-forming as the New York Stock and Exchange Board the broker organization began renting out space exclusively for securities trading, which previously had been taking place at the Tontine Coffee House. Several locations were used between 1817 and 1865, when the present location was adopted.
The NYSE announced its plans to merge with Archipelago on April 21, 2005, in a deal intended to reorganize the NYSE as a publicly traded company. NYSE's governing board voted to merge with rival Archipelago on December 6, 2005, and became a for-profit, public company. It began trading under the name NYSE Group on March 8, 2006. A little over one year later, on April 4, 2007, the NYSE Group completed its merger with Euronext, the European combined stock market, thus forming NYSE Euronext, the first transatlantic stock exchange.
On September 16, 1920, a bomb exploded on Wall Street outside the NYSE building, killing 33 people and injuring more than 400. The perpetrators were never found. The NYSE building and some buildings nearby, such as the JP Morgan building, still have marks on their facades caused by the bombing.
Similarly, there was a panic in the financial world during the year of 1997; the Asian Financial Crisis. Like the fall of many foreign markets, the Dow suffered a 7.18% drop in value (554.26 points) on October 27, 1997, in what later became known as the 1997 Mini-Crash but from which the DJIA recovered quickly. This was the first time that the "circuit breaker" rule had operated.
On May 6, 2010, the Dow Jones Industrial Average posted its largest intraday percentage drop since the October 19, 1987, crash, with a 998-point loss later being called the 2010 Flash Crash (as the drop occurred in minutes before rebounding). The SEC and CFTC published a report on the event, although it did not come to a conclusion as to the cause. The regulators found no evidence that the fall was caused by erroneous ("fat finger") orders.
The New York Stock Exchange (sometimes referred to as "the Big Board") provides a means for buyers and sellers to trade shares of stock in companies registered for public trading. The NYSE is open for trading Monday through Friday from 9:30 am Ė 4:00 pm ET, with the exception of holidays declared by the Exchange in advance.
In the mid-1960s, the NYSE Composite Index (NYSE: NYA) was created, with a base value of 50 points equal to the 1965 yearly close. This was done to reflect the value of all stocks trading at the exchange instead of just the 30 stocks included in the Dow Jones Industrial Average. To raise the profile of the composite index, in 2003 the NYSE set its new base value of 5,000 points equal to the 2002 yearly close. Its close at the end of 2013 was 10,400.32.
In April 2011, Intercontinental Exchange (ICE), an American futures exchange, and NASDAQ OMX Group had together made an unsolicited proposal to buy NYSE Euronext for approximately US$11,000,000,000, a deal in which NASDAQ would have taken control of the stock exchanges. NYSE Euronext rejected this offer twice, but it was finally terminated after the United States Department of Justice indicated their intention to block the deal due to antitrust concerns.
The signal to start and stop trading was not always a bell. The original signal was a gavel (which is still in use today along with the bell), but during the late 1800s, the NYSE decided to switch the gavel for a gong to signal the day's beginning and end. After the NYSE changed to its present location at 18 Broad Street in 1903, the gong was switched to the bell format that is currently being used.
Many of the people who ring the bell are business executives whose companies trade on the exchange. However, there have also been many famous people from outside the world of business that have rung the bell. Athletes such as Joe DiMaggio of the New York Yankees and Olympic swimming champion Michael Phelps, entertainers such as rapper Snoop Dogg, members of ESPNís College GameDay crew, singer and actress Liza Minnelli and members of the band Kiss, and politicians such as Mayor of New York City Rudy Giuliani and President of South Africa Nelson Mandela have all had the honor of ringing the bell. Two United Nations Secretaries General have also rung the bell. On April 27, 2006, Secretary-General Kofi Annan rang the opening bell to launch the United Nations Principles for Responsible Investment. On July 24, 2013, Secretary-General Ban Ki-moon rang the closing bell to celebrate the NYSE joining the United Nations Sustainable Stock Exchanges Initiative.
