Xinhua News Agency, June 12, the Shenzhen Stock Exchange revised and issued the "guidelines on self-discipline Supervision of listed companies on the Shenzhen Stock Exchange-- Assessment of Information Disclosure work" and solicited opinions from the public. This revision first adjusts the benchmark score to 80 points, and on this basis, combined with the new situation faced by day-to-day supervision and new problems to be solved, add some additional and subtractive items. By adding sub-items to guide companies to hold regular performance presentations, to strengthen investor relations management, to participate in the joint construction of a good market ecology, and to encourage listed companies to innovate information disclosure forms, to help investors understand listed companies more succinctly and intuitively. At the same time, although some violations of information disclosure of listed companies do not meet the standard of disciplinary action, they may affect stock trading and damage the rights and interests of investors, and strengthen supervision by deducting points. For example, listed companies cater to or improperly relate to market hotspots through interactive platforms, official websites, official accounts or other means, deliberately exaggerating the impact of related matters on the company's production, operation, research and development, sales, development, etc., improperly affecting the price of the company's shares and its derivative varieties, up to six points can be deducted.
