Chinese stocks tumble again as other Asian markets rebound

Chinese stocks tumbled again Tuesday after their biggest decline in eight years while most other Asian markets rebounded from a day of heavy losses.

The mixed picture comes after a tumultuous day on Wall Street, where the Dow Jones industrial average ended down 3.6 percent after trimming much bigger losses. European markets were also hit badly. Analysts said it was unclear whether this was a sign the worst was over, or a reprieve in a longer-term bear market.

The declines in China were less severe. The Shanghai Composite Index was down 4.3 percent at 3,071.06 at midday Tuesday after falling 6.4 percent in the first minutes of trading. On Monday, it plummeted 8.5 percent.
