(economic Daily: stock price manipulation and insider trading must be punished)-- an article in the Economic Daily pointed out that the harm of market manipulation is self-evident by harming the interests of the majority and exchanging ill-gotten gains for the minority. It destroys the "three public" principle of the market, conceals the real relationship between supply and demand of the market, distorts the function of market resource allocation, especially some highly leveraged manipulation, and may even lead to systemic financial risks, which cannot be avoided. Regulatory policies continue to strengthen, investors should also enhance their awareness of self-protection, stay away from all speculation, must not "help evil". Only when the regulatory authorities adhere to strict supervision, zero tolerance, and investors adhere to value investment and long-term investment, can we clean up the filth, get to the root of the problem, and create a standardized, transparent, open, dynamic and resilient capital market.
