BEIJING, March 14 (Xinhua) -- The Shanghai Stock Exchange (SSE) is proposing to raise the maximum share price fluctuation for listed companies from 10 percent to 20 percent per day.

The move is part of a package of proposals for changing trading mechanisms based on a study jointly conducted by SSE and Guotai Junan Securities Co. Ltd.

The proposals are reportedly aimed at satisfying the different market demands of investors.

Researchers analyzed questionnaires submitted by investors from 23 regional branches and five subsidiaries of Guotai Junan Securities.

They found that the current 10 percent price rise limit had fueled price fluctuations after the stock trading was suspended and it had been ineffective in stopping sharp falls.

There are no price limits in mature stock markets, for example, the New York Stock Exchange and Hong Kong Stock Exchange.

The researchers suggest China should gradually abolish the price limit and recommended a "circuit breaker", which halts trading when the stock moves up or down by a certain percentage, to enable investors to take a cooler, more rational view of the stocks.

With rising incomes, Chinese investors are increasingly turning to stocks as a way to invest their extra cash. On Feb. 27, Chinese stocks suffered their biggest single-day fall in a decade, plunging 8.8 percent.
