The main purpose of securities law to restrict securities practitioners from buying and selling stocks is to prohibit insider trading. The so-called prohibition of insider trading refers to the insider of securities trading and the person who illegally obtains insider information. Before the inside information is made public, you may not buy or sell the securities of the company, you may not disclose the information, and you may not advise others to buy or sell the securities. If insider trading causes losses to investors, the actor shall be liable for compensation according to law. Those who meet the criminal standards must of course be investigated for criminal responsibility.
According to the above contents, we can analyze the problem from the following three aspects: first, whether the securities practitioners have obtained relevant news; Secondly, whether this information constitutes insider information in the Securities Law (that is, undisclosed information related to the company's operation, finance or the company's securities market price in securities trading activities); Third, whether this information has not been made public.
If the above three aspects are met at the same time, securities practitioners are prohibited from buying securities related to insider trading, and should also avoid engaging in insider trading in the name of their families.
If the above three aspects are not involved, the law does not explicitly prohibit securities practitioners and their families from buying stocks.
