Self-Regulatory Organizations (SROs) are non-governmental entities that create and enforce rules and standards for their members. They play a crucial role in maintaining ethical practices and ensuring compliance within specific industries, such as finance and securities. Examples of SROs include the Financial Industry Regulatory Authority (FINRA) and the National Association of Securities Dealers (NASD). SROs help protect the interests of the public and maintain market integrity by overseeing member activities. They often have the authority to impose penalties, conduct audits, and provide training to ensure that their members adhere to established regulations and best practices.
