Stocks tumble the most in six weeks

China stocks fell the most in six weeks with the benchmark Shanghai Composite Index losing for a fourth day, falling 1.2 percent on Tuesday to close at 2,272.42.

Stocks fell over uncertainties in demand for consumer appliances in next six months and due to slumping shares in small firms. Analysts said more confidence in macroeconomics may help stocks to rally.

The CSI 300 Index dropped 1.4 percent to 2,565.67, with all 10 sectors falling by at least 1 percent.
