Dealers in the stock exchange such as bulls, bears, and stags are categorized as "speculators." Speculators are individuals or entities who buy or sell financial assets, such as stocks, bonds, or commodities, in the hope of making a profit from price fluctuations. They are often motivated by the potential for high returns, but they also face significant risk due to the volatility of financial markets. In the context of the stock exchange, bulls are speculators who believe that stock prices will rise, and therefore buy stocks in the hope of selling them later at a higher price. Bears, on the other hand, are speculators who believe that stock prices will fall, and therefore sell stocks in the hope of buying them back at a lower price. Stags are speculators who buy stocks at the time of the initial public offering (IPO), hoping to sell them later at a profit when the price goes up due to high demand. In contrast, an actuary is a professional who uses mathematical and statistical methods to analyze and assess financial risk, usually in the context of insurance or pension plans. Promoters are individuals or companies who promote and market a particular product, service, or idea to the public. An underwriter is a financial institution or individual who assumes the risk of buying new securities from a company and reselling them to the public. They are not typically involved in the buying and selling of securities on the stock exchange.
