Equity trading involves buying and selling shares of publicly traded companies, known as stocks. Investors participate in equity trading to gain ownership in a company and potentially earn profits through price appreciation or dividends. This trading can occur on various platforms, including stock exchanges like the New York Stock Exchange or NASDAQ. Traders can employ different strategies, such as day trading, where they buy and sell stocks within the same day, or long-term investing, where they hold shares for extended periods. The goal is to capitalize on market movements and make informed decisions based on market analysis and trends.
