What is a stock exchange?
A stock exchange is a marketplace for the buying and selling of shares, bonds and securities. Stock exchanges can serve as a measure for the health of the national economy, and can also be a key indicator of world economic strength. This is because the growth of the financial market equates to higher standards of living and employment rates.
Traditionally, stock exchanges were physical buildings in each country of operation, but with the shift toward electronic trading many have closed their trading floors and switched to online platforms.
However, the institutions themselves are still around, and some of them are bigger than ever with market capitalisations of trillions of dollars.

- New York Stock Exchange
- NASDAQ
- Euronext
- Shanghai Stock Exchange
- Tokyo Stock Exchange
- Shenzhen Stock Exchange
- Hong Kong Stock Exchange
- National Stock Exchange of India
- London Stock Exchange
- Saudi Exchange
New York Stock Exchange - $25tn
The New York Stock Exchange (NYSE) is located on Wall Street in New York. It was founded in 1817, but it didn’t operate under the NYSE name until 1963.
The New York Stock Exchange Group had a turbulent road to its top spot, with infamous events such as the Wall Street Crash in 1929 and Black Tuesday in 1987.
But it has remained the largest stock exchange in the world by market capitalisation ever since the end of World War I, when it overtook the London Stock Exchange. In 2012, the NYSE was taken over by an American futures exchange group, Intercontinental Exchange.
The New York Stock Exchange’s market capitalisation was $25 trillion in August 2024 – this is over 20% of the total world stock market value. There are over 2400 companies listed on the New York Stock Exchange, which span sectors such as finance, healthcare, consumer goods and energy.
Some of its more famous companies include Exxon Mobil Corp (XOM), Citigroup Inc (C) and Pfizer Inc (GE) – the Dow Jones is the most used index for tracking the value of the NYSE, but components can also be listed on the NASDAQ.
NASDAQ - $21.7tn
The NASDAQ stock exchange is also in New York, located in the famous Times Square. It stands for National Association of Securities Dealers Automated Quotations and was founded by a group of local stockbrokers in 1971.
The NASDAQ is unusual in that it never operated on an open outcry system; instead it has always used a computer and telephone-based system of trading, which made it the first electronic stock exchange.
The NASDAQ market capitalisation reached $21.7 trillion in 2024, which places it as the second largest stock exchange.
However, it has the largest market capitalisation of technology stocks – some of the NASDAQ’s top listed companies include Apple (APPL), Microsoft (MSFT) and Tesla (TSLA). The index used to measure the performance of the exchange is the Nasdaq 100.
Euronext Stock Exchange - $7.2tn
The Euronext Stock Exchange is based in Amsterdam, Netherlands, but it is a pan-European exchange – it spans the Netherlands, Portugal, Belgium, France, Ireland and the UK. It was founded in 2000 to represent the economy of Europe as a whole, which is why it operates in euros.
In 2007, Euronext merged with the NYSE Group to form NYSE Euronext, and in 2013, Intercontinental Exchange took over the exchange completely. Then, in June 2014, Euronext went public in order to become a standalone company again.
Euronext is now the third largest stock exchange in the world, with a market capitalisation of $7.2 trillion. Because the exchange includes several countries, there are 1300 listed companies and 30 stock indices that can be used to track its performance.
However, the dominant stock index for Euronext-listed companies is the Euronext 100, which is made up of the largest and most liquid stocks on the Euronext Stock Exchange – including AXA, Christian Dior and Renault.
Shanghai Stock Exchange - $6.7tn
The Shanghai Stock Exchange (SSE) is one of three independent stock exchanges in the People’s Republic of China – the other two being Shenzhen and Hong Kong, which also feature on this list.
The Shanghai Stock Exchange is the fourth largest stock exchange in the world, despite the fact it was only founded in 1990. The exchange’s origins do actually date back to 1866, but it was suspended in 1949 due to the Chinese revolution.
Each stock listed on the SSE has ‘A’ shares that are priced in the local yuan currency, and ‘B’ shares that are quoted in US dollars. ‘A’ shares are for domestic investment only, with the exception of investors who qualify for the foreign investment scheme, while ‘B’ shares are available to both domestic and foreign investors.
The Shanghai Stock Exchange’s market capitalisation reached $6.7 trillion in August 2024. Traders can track the performance of stocks listed on the Shanghai Stock Exchange using the SSE Composite index, also known as the Shanghai Composite.
This includes the largest stocks on the Shanghai Stock Exchange, such as PetroChina, the Industrial and Commercial Bank of China and the Agricultural Bank of China.
Tokyo Stock Exchange - $5.9tn
The Tokyo Stock Exchange (TSE) was founded in 1878 and is the largest stock exchange in Japan. The TSE did face problems post World War II – and was even suspended between August 1945 and April 1949 – due to the country’s involvement in the war.
It was rebranded in 1949, and is now commonly known under the name of its owner: Japan Exchange Group. The group was formed in the merger between the Osaka Securities Stock Exchange and the TSE in 2013. The Tokyo Stock Exchange now partners with other exchanges all over the world, including the London Stock Exchange.
Today, there are over 3575 companies listed on the Tokyo Stock Exchange, which has taken the TSE’s market capitalisation to $5.9 trillion as of August 2024. The Tokyo Stock Exchange’s benchmark index is the Nikkei 225, which includes the top companies listed on the TSE such as Honda Motor Co, Toyota Motor Corp and Sony Corp.
Shenzhen Stock Exchange - $4.5tn
The Shenzhen Stock Exchange (SZSE) is the third exchange of the People’s Republic of China. Although it was founded in 1987, it wasn’t formally operational until 1990. The SZSE is a self-regulated body, but it is supervised by the China Securities Regulatory Commission (CSRC).
The Shenzhen Stock Exchange had a market capitalisation of $4.5 trillion in August 2024, which made it the sixth largest stock exchange in the world.
The SZSE trades shares in Chinese yuan because the companies listed on the Shenzhen Stock Exchange are primarily based in China. The Shenzhen Stock Exchange is also home to the SME Board established in 2004 for businesses in the manufacturing sector, and the ChiNext board, which was launched in 2009 to replicate the NASDAQ’s focus on technology start-ups.
Hong Kong Stock Exchange - $4.2tn
The Hong Kong Stock Exchange (SEHK) was founded in 1891 by the Association of Stockbrokers in Hong Kong – it was renamed the Hong Kong Stock Exchange in 1914. The SEHK is one of the three stock exchanges in China, but the physical trading floor of the SEHL was closed in 2017 because of the shift toward electronic trading.
The Stock Exchange of Hong Kong is the fourth-largest stock exchange in Asia, and the seventh largest in the world with a market capitalisation of $4.2 trillion in August 2024. The Hong Kong Stock Exchange trades in Hong Kong Dollars (HKD), as the companies listed are primarily based in Hong Kong.
There are 1955 companies listed on the Hong Kong Stock Exchange – a large portion of the Hong Kong Stock Exchange’s market capitalisation comes from its 20 largest stocks, which include AIA, Tencent Holdings and HSBC Holdings.
National Stock Exchange of India - $3.5tn
The National Stock Exchange of India (NSE) was founded in 1992 as the first dematerialised electronic exchange in India. It began operations in 1994, bringing automated screen-based trading to the Indian securities market. The NSE played a crucial role in reforming the Indian securities market by providing a modern, fully automated screen-based trading system with national reach.
The NSE's market capitalisation reached $3.5 trillion in August 2024, making it the eighth-largest stock exchange in the world. It lists over 1,600 companies across various sectors, including information technology, pharmaceuticals, and finance. The exchange's flagship index is the NIFTY 50, which includes top Indian companies such as Reliance Industries, Tata Consultancy Services, and HDFC Bank.
The NSE has been instrumental in developing the Indian capital market, introducing products like index futures, index options, and equity derivatives. It also operates in the wholesale debt market and currency derivatives segments, making it a comprehensive exchange for various financial instruments.
London Stock Exchange - $3.4tn
The London Stock Exchange (LSE) was founded in 1801, but its origins date back to 1698 when the LSE’s service was nothing more than a twice-weekly paper publication of market prices.
This makes it the one of the oldest stock exchanges in the world. It was actually the largest stock exchange in the world up until the end of World War I, when it was dethroned by the NYSE. The LSE is now the ninth largest stock exchange in the world.
The LSE is owned by the London Stock Exchange Group, which was created in 2007 when the LSE merged with the Borsa Italiana. It is the most international stock exchange, with over 3000 companies across 70 countries.
The market capitalisation of the London Stock Exchange was $3.4tn in August 2024. Traders can track the performance of the LSE, and its market capitalisation, with the Financial Times Stock Exchange Index 100 Share Index, or FTSE 100.
The index contains the top 100 companies listed on the London Stock Exchange – including Barclays, BP and GlaxoSmithKline. There are other indices that can be used to track the London Stock Exchange-listed companies, including the FTSE 250, the FTSE Small Cap and the FTSE All-Share.
Saudi Exchange - $3.1tn
The Saudi Exchange, formerly known as the Saudi Stock Exchange (Tadawul), is the sole stock exchange in Saudi Arabia. It was officially formed in 2007, but its origins can be traced back to 1935 when the Arab Automobile Company became the first joint-stock company to be traded in Saudi Arabia.
As of August 2024, the Saudi Exchange's market capitalisation stood at $3.1 trillion, placing it as the tenth-largest stock exchange globally. This significant growth reflects Saudi Arabia's efforts to diversify its economy and attract foreign investment, particularly following the partial privatisation of Saudi Aramco in 2019.
The exchange lists over 200 companies, predominantly from sectors such as petrochemicals, banking, and telecommunications. Its main index is the Tadawul All Share Index (TASI), which includes major companies like Saudi Aramco, Saudi Basic Industries Corporation (SABIC), and Al Rajhi Bank.
The Saudi Exchange has been modernising its infrastructure and regulations to align with international standards. In 2015, it opened to qualified foreign investors, and in 2019, it was included in major emerging market indices, further boosting its global profile and attracting more international capital.
