Stocks down for fourth session

China's main indexes fell for the fourth session on Friday, pressured by tech stocks - as faster approval of IPOs exacerbated concerns over the valuations of smaller-cap stocks.

The blue-chip CSI300 index rose 0.1 percent, to 3,319.91 points, while the Shanghai Composite Index lost 0.2 percent to 3,112.76 points.

For the week, the CSI was down 0.9 percent, while the SSEC was down 1.3 percent.
