The stock market is a collection of markets and exchanges where activities related to the buying, selling, and issuance of shares of publicly traded companies take place. It serves as a platform for investors and traders to engage in the exchange of securities, including stocks, bonds, and other financial instruments. The stock market reflects the economic health and performance of companies listed on stock exchanges, providing insights into market conditions and investor sentiment.

The stock market operates through various exchanges, such as the New York Stock Exchange (NYSE) and the Nasdaq, where stock prices are determined by supply and demand dynamics. Participants in the stock market include individual investors, institutional investors, and traders, all of whom contribute to price fluctuations through their buying and selling activities. It also plays a critical role in the overall economy by enabling companies to raise capital for growth and expansion while providing opportunities for investors to earn returns on their investments. The stock market is often seen as a barometer of economic performance and can influence financial conditions globally.
