CHINA’S record-high trade surplus was the tonic for the Shanghai Composite Index to surpass 3,000 points for the first time in more than three and a half years yesterday.

The index jumped 2.81 percent to 3,020.26 points. The last time it passed 3,000 was on April 22, 2011.

Investors must consider risks while putting money into stocks, China’s securities regulator warned yesterday after a buying spree fueled a 21 percent surge in the Shanghai index over the past month.
