SHANGHAI - China's rising stock market this week has resulted in an increase in the market capitalization of the two bourses in Shanghai and Shenzhen.

The aggregate circulated market value of the Shanghai and Shenzhen bourses rose to 37 trillion yuan ($5.7 trillion) by Friday's market close, up 3.27 percent from the previous week.

There are 1,092 and 1,762 listed companies in Shanghai and Shenzhen, with price-earnings ratios of 15.43 and 42.85.

From Monday to Friday, the benchmark Shanghai Composite Index and the smaller Shenzhen index went up 3.12 and 3.07 percent, while the NASDAQ-style ChiNext Index gained 3.58 percent.

The bullish week can be attributed to improving investor sentiment amid a slew of better-than-expected economic indicators including export, fixed-asset investment and the index tracking factory activity.
