Boy, was I wrong about stock exchanges!
I just took a look at share trading volumes for 2010, and there has been a major re-shuffling of the world’s exchanges, in terms of the annual dollar-value of their electronic order books.
Here’s a screen-shot —
Dollar amounts are shown in millions of USD.
So, the NYSE figure is $17.80 trillion/year, Nasdaq is $12.66 trillion/year, etc.
The big change is that Shanghai and Shenzhen have taken over the #3 and #5 spots, dropping London from #3 to #6. Tokyo has held onto the #4 spot. Other surprising changes took place over the 4 years from 2006 to 2010.
Figures for 2011 should be released by the WFE in the near future.
The screen-shot shows only the first 21 exchanges in the WFE ranking. Refer to the source-document for a complete listing.
Here’s a link to the WFE webpage where you can download the source-document for the screen-shot shown above —
