The main requirement for admission to the second-tier securities markets is the disclosure of all trading activities. This means that companies seeking to be listed on the second-tier securities markets are required to provide detailed information about their financial status, trading activities, and other relevant information that investors would need to make informed decisions. This information is made public and available to potential investors, which helps to promote transparency and build confidence in the company. By meeting this requirement, companies can gain access to additional sources of funding and potentially increase their visibility and prestige.
