Beijing bourse tells 'major shareholders' to refrain from selling, sources say

SHANGHAI/BEIJING Nov 27 (Reuters) - The Beijing Stock Exchange has de facto implemented a new policy that prevents major shareholders of companies listed on the bourse from selling stock, worried that such sales could douse a long-desired rally, three people familiar with the matter said on Monday.

The bourse said in a statement to Reuters on Tuesday that talk of such a policy was "not factual", and there was "no change to the spirit of relevant published guidelines".

A "major shareholder" is one with a stake of 5% or more and is required to make a public filing with the relevant stock exchange before selling shares, according to rules for China's bourses.

The Beijing exchange has been rejecting those filings, said the people who were not authorised to speak to media and declined to be identified.

It was not immediately clear how long this new policy would remain in place, they added.

The Beijing Stock Exchange, launched two years ago, was set up to help facilitate funding for innovative small companies, dubbed "little giants", but had languished due to lack of investor interest.

But its benchmark 50 Index has surged 46% this month on the back of recent measures by authorities. These include lowering the required amount of funds an investor must have in their stock account to invest, improving trading mechanisms and encouraging mutual funds to participate in the market.

The bourse had said separately in a statement on Monday morning ahead of this Reuters article that it was closely monitoring trading to ensure normal market order.

The China Securities Regulatory Commission did not reply to a request for comment.

The so-called window guidance - where directives are made orally without written documents - is aimed at protecting the rally, the sources said.

One noted that without the guidance, the share price surge "could prompt institutional shareholders to reduce their holdings which could knock the index down again."

The Beijing bourse currently houses 232 companies with a combined market capitalisation of 366 billion yuan ($50 billion).

By comparison, the Shanghai bourse is home to 2,256 firms worth 47 trillion yuan in total, while almost 3,000 companies listed in Shenzhen have a total market capitalisation of 31.9 trillion yuan.
