Looking at stock market capitalization by country gives some insight into how countries, and stocks, are doing. Looking at the total market capitalization by country doesn’t equate to the stock holdings by individuals in a country or the value of companies doing work in a specific country. Some countries (UK and Hong Kong, for example) have more capitalization based there than would be indicated by the size of their economy.
It is important to keep in mind the data is in current USA dollars, so big swings in exchange rates can have a big impact (and can cause swings to be exacerbated when they move in tandem with stock market movements – if for example the market declines by 15% and the currency declines by 10% against the US dollar those factors combine to move the result down).

As with so much recent economic data China’s performance here is remarkable. China grew from 1.8% of world capitalization in 2000 to 6.9% in 2012. And Hong Kong’s data is reported separately, as it normally is with global data sets. Adding Hong Kong to China’s totals would give 3.7% in 2000 with growth to to 8.9% in 2012 (Hong Kong stayed very stable – 1.9% in 2000, 2% in 2012). China alone (without HK) is very slightly ahead of Japan.
The first chart shows the largest 4 market capitalizations (2012: USA $18.6 trillion, China and Japan at $3.7 trillion and UK at $3 trillion). Obviously the dominance of the USA in this metric is quite impressive the next 7 countries added together don’t quite reach the USA’s stock market capitalization. I also including the data showing the global stock market capitalization divided by 3 (I just divide it by three to have the chart be more usable – it lets us see the overall global fluctuations but doesn’t cram all the other data in the lower third of the chart).
Canada is the 5th country by market capitalization (shown on the next chart) with $2 trillion. From 2000 to 2012 China’s market capitalization increased by $3.1 trillion. The USA increased by $3.6 trillion from a much larger starting point. China increased by 536% while the USA was up 23.5%. The world stock market capitalization increased 65% from 2000 to 2012.
