Share trading involves buying and selling shares of publicly listed companies on a stock exchange like the NYSE or NSE. Investors purchase shares to gain profits either through price appreciation or dividends. Trading can be short-term (day trading) or long-term (investing). The stock market is influenced by economic news, company performance, and global events. Traders often use technical analysis, charts, and indicators to predict price movements. It carries risks, especially in volatile markets, but also offers opportunities for wealth creation. Beginners should start with proper research, risk management, and ideally, seek guidance or use demo accounts before investing real money.
