Value of stocks rises above $10 trillion, margin debt reaches new record

The value of Chinese stocks has risen above $10 trillion for the first time, the latest milestone for the nation's world-beating rally.

Companies with a primary listing in China are valued at $10.05 trillion, an increase of $6.7 trillion in 12 months, according to data compiled by Bloomberg. The gain alone is more than the $5 trillion size of Japan's entire stock market. The US stock market at almost $25 trillion is the largest globally.

No other stock market has grown as much in dollar terms in a 12-month period, as Chinese individuals piled into the nation's equities using borrowed funds to bet gains will continue.
