Share prices plummet amid uncertainties

The Chinese mainland's stock market dropped sharply on its first trading day in October, due to overseas market fluctuations and uncertainties during the week-long National Day holiday.

The benchmark Shanghai Composite Index slumped 3.72 percent to close at 2716.51 points on Monday, while the Shenzhen Component Index went down 4.05 percent to 8060.83 points.

More than 3,200 stocks, accounting for about 90 percent of the A-share market, closed lower, and the net outflow through stock connect programs reached 9.6 billion yuan ($1.4 billion), the second highest level this year.
