Who among among the following is not function of a stock exchange market?

The promoter is not a function of a stock exchange market. A promoter is an individual or group of individuals who bring together the necessary resources to start a business or corporation. They are responsible for raising capital, organizing the company's structure, and creating a business plan. Promoters are involved in the initial stages of a company's formation and are not typically involved in the ongoing trading of its stock. In contrast, a stock exchange is a platform where securities such as stocks, bonds, and derivatives are bought and sold. The primary functions of a stock exchange include providing a market for the trading of securities, facilitating the issuance of new securities, and providing liquidity to investors. Bulls are investors who anticipate a rise in the price of stocks and other securities and seek to profit from it. Brokers are intermediaries who facilitate the buying and selling of securities on behalf of investors. Jobbers are market makers who buy and sell securities on their own account to provide liquidity to the market. Overall, while promoters play a crucial role in the formation of a company, they are not directly involved in the ongoing trading of its stock and therefore not a function of a stock exchange market.
