The Securities and Exchange Act defines proper market practice in Korea. It provides policies on investor protection, prevention of insider trading, and information disclosure in consonance with other laws such as the Futures Trading Act, Collective Investment Scheme Act, and Commercial Code.

The Korea Securities Dealers Association (KSDA) is a self-regulatory organization established under the Securities and Exchange Act. One of its aims is to protect investor interests and ensure fair business/trading practices. The KSDA Regulations on Business Conduct of Securities Companies is linked below.

After the stock exchange, Kosdaq, and futures exchange merged to become the Korea Exchange (KRX), the Market Surveillance and Oversight Commission was reestablished and given responsibility over KRX self-regulation. The Commission maintains market order, prevents unfair trading practices, and handles disputes between market participants. Below are links to KRX regulations regarding ethical market practices.
