The stock market is a complex system where investors buy and sell shares of publicly traded companies, aiming to profit from price fluctuations. It is influenced by a wide range of factors, including economic data, company performance, and global events. Stock prices are determined by supply and demand, with investors reacting to news, earnings reports, and broader market trends. While the potential for high returns is appealing, the stock market also carries significant risk, with prices often being volatile in the short term. Successful investors typically focus on long-term strategies, diversifying their portfolios, and staying informed about market conditions.
