Investors cheered amid stimulus talk

Main stock indexes all surge more than 3% in biggest gain in more than two months

Stocks rallied on Tuesday with the biggest gain in more than two months as weaker-than-expected economic data sparked fresh expectation of further stimulus policies and an acceleration of reforms for the country's lumbering State-owned enterprises.

The benchmark Shanghai Composite Index gained 3.22 percent to close at 3,007.74 points, the Shenzhen Component Index jumped by 3.41 percent, and the startup index ChiNext rose by 3.07 percent.
