China’s stocks fell, sending the benchmark index toward its steepest weekly loss since 2008, amid concern the government will clamp down on margin trading and valuations are excessive after a world-beating rally over the past year.

The Shanghai Composite Index dropped 1.5 percent to 4,712.15 at 9:33 a.m., extending losses to 8.7 percent this week. The China Securities Regulatory Commission is working on margin-trading risk management rules for securities firms, the 21st Century Business Herald reported, without citing anyone.
