Alongside the widely recognised New York Stock Exchange (NYSE) and NASDAQ, there are a number of other US-based exchanges, such as the National Stock Exchange (NSX) and the Chicago Stock Exchange (CHX).

However, many of the smaller exchanges have now been swallowed up by larger corporations. For example, the Philadelphia Stock Exchange (PHLX) is now owned by NASDAQ OMX, as is the Boston Stock Exchange.

The Australian stock market has a similar story. Prior to 1987, Australia had six main stock exchanges, which were then amalgamated to create the Australian Stock Exchange. In 2006, the Australian Stock Exchange and the Sydney Futures Exchange merged to create The Australian Securities Exchange (ASX), which became the ASX Group in 2010.

While the ASX is now Australia's primary stock exchange, there are smaller exchanges, such as the National Stock Exchange of Australia (NSX), listing small to medium enterprises, with around 70 securities and a market cap of AUD $2 billion, as well as Chi-X Australia, owned by Chi-X Global.

New York Stock Exchange (NYSE)

If we're going to compare US stock exchanges, what better place to start than the New York Stock Exchange, headquartered in New York City. In November 2013, NYSE Euronext was acquired by IntercontinentalExchange (NYSE: ICE), making it the leading global network of regulated exchanges and clearing houses.

It now includes 23 regulated exchanges and marketplaces, including the ICE futures exchanges in the US, Canada and Europe, the Liffe futures exchanges in the US and Europe, the New York Stock Exchange, the Euronext group of stock exchanges, the Equity options exchanges, and the OTC energy, credit and equity markets.

It also has five central clearing houses, 9700 traded contracts and securities across all major asset classes, $59 billion in capital as of 2013, and is home to 90% of the DJIA and 78% of S&P 500.


The other US giant is NASDAQ OMX, also headquartered in New York City. NASDAQ OMX has 26 markets, three clearing houses and five central securities depositories spanning six continents. It has 3300 listed companies, and has $7 trillion in market capitalisation. NASDAQ also powers 80 exchanges in 50 countries with its trading technology.


As Australia's main stock exchange, the ASX is one of the world's largest exchanges, ranked within the top ten according to market capitalisation. The ASX has a total market capitalisation of around $1.5 trillion, and has 6.7 million share owners, 180 participants, and around 2,200 listed companies and issuers.
