4 percent drop puts brakes on bull market

Chinese stocks slumped by more than 4 percent on Tuesday, the biggest daily drop in three months, amid speculation that the top securities regulator may take measures to control market bubbles.

The benchmark Shanghai Composite Index fell sharply to 4,298.71 points at the close, a drop of 4.06 percent.

More than 1,900 of the A-shares listed in Shanghai and Shenzhen, or 80 percent of the total, suffered declines, led by the telecommunication and property sectors.
