Find out how you can invest in the world’s largest stock exchanges.
Market capitalisation (often referred to as “market cap”) is the total value of a company’s outstanding shares of stock. It’s pretty easy to calculate – it’s just the total outstanding shares multiplied by the market value of one share.
To find the market cap of a stock exchange, you add up the market capitalisation of all of the companies in the exchange. The biggest stock exchanges each have market capitalisations of more than US$6 trillion.
The New York Stock Exchange is the world’s largest stock exchange by market capitalisation. Its market capitalisation is US$25.62 trillion (around £18 trillion). It’s home to some of the most recognisable brands in the world such as Twitter, Spotify and Walt Disney.
The NYSE opening hours are 9:30am to 4pm ET, which is 2:30pm to 9pm GMT.
NASDAQ (sometimes referred to as Nasdaq) is the world’s second largest stock exchange by market capitalisation. It started as the world’s first electronic stock market as a quotation system. NASDAQ’s market capitalisation is US$19.51 trillion (around £13.75 trillion). There are some major well-known companies on NASDAQ, including the “FAANG stocks“, Facebook, Apple, Amazon, Netflix and Alphabet (Google).
The NASDAQ exchange opening hours are from 9:30 am to 4pm ET, which is 2:30pm to 9pm GMT.

The bad news is that if you’ve got dreams of investing in the Shanghai Stock Exchange, you can’t.

All investing should be regarded as longer term. The value of your investments can go up and down, and you may get back less than you invest. Past performance is no guarantee of future results. If you’re not sure which investments are right for you, please seek out a financial adviser. Capital at risk.
