Investors can buy and sell shares of publicly traded corporations on the stock market. These shares signify ownership in the business and can be traded for money or ownership interests. An Initial Public Offering (IPO), which entails registering with regulatory agencies, revealing financial information, and issuing shares to the public, is how companies go public. Shares of the business are traded on stock exchanges after being listed, with pricing based on supply and demand. Investors gain from price growth, dividends, and occasionally voting rights based on their ownership of shares.
