Market supervision refers to the oversight and regulation of financial markets to ensure they operate fairly and transparently. This involves monitoring trading activities, enforcing rules, and protecting investors from fraud and manipulation. Regulatory bodies, such as the Securities and Exchange Commission (SEC) in the United States, play a crucial role in maintaining market integrity. Effective market supervision helps to build trust among investors and promotes healthy competition. By ensuring that companies disclose accurate information and adhere to established guidelines, market supervisors contribute to a stable economic environment. This ultimately benefits both consumers and businesses in the long run.
