Here's a fascinating projection that Credit Suisse Research just tweeted.
By 2030, Credit Suisse expects the global stock market to balloon to $284.2 trillion and look like what you see below.
According to the World Federation of Exchanges, the total value of stocks in the top 60 major stock market exchanges was $62.4 trillion as of July 2014.
"The United States retains its ranking as the largest global equity market with a (nominal dollar) capitalization of USD 98 trillion, with a weight of 34.6% (representing a USD 74 trillion gain since 2014), while China advances ahead of both the UK and Japan to become the second largest equity market with a USD 54 trillion capitalization and a weight of 18.9% (representing a USD 50 trillion nominal gain from 2014)," wrote Credit Suisse analysts.
