The capital market has a very important role in the economy of a country and in general economic activities. In many countries that adopt a market economy system, the capital market has become one of the sources of economic progress, because the capital market can be an alternative source of funds for companies. However, the capital market is quite vulnerable to crime by irresponsible parties who want to get quick profits to the detriment of other parties. This can be seen in the case PT Tiga Pilar Sejahtera Food Tbk. This, the problem that is raised in this paper is how to regulate the prohibition of market misleading information or material facts in the capital market and how to provide legal protection for investors due to misleading information or material facts in the capital market. This study aims to determine misleading information or material facts in the capital market and to find out the legal protection for investors who are exposed to misleading information or material facts in the capital market. The author uses normative research methods, literature studies and normative juridical approaches, and analyzes data with qualitative analysis methods. The results found are that misleading information or material facts is a prohibited act which has been regulated in Law Number 8 of 1995 concerning Capital Markets, namely articles 90 letter c and 93, and investors who feel aggrieved can report these actions to Indonesia’s Financial Services Authority (OJK).
