Ping An Insurance (Group) of China Ltd, the world's second-biggest life insurer by market value, will keep stock investments at around 10 percent of its portfolio in the second half, despite possible market fluctuations ahead, its group president said yesterday.

"Some market fluctuations are natural. In the long run, we are optimistic about the A-share market, since there is a good economic trend in the country," said Louis Cheung, group president, at a press conference to announce the company's first-half results.

"We think 10 percent on equity investments is a rational ratio. We will also consider investments in commercial property, which could produce stable income and also help resist inflation," Cheung said.
