Public corporations are companies that are owned by shareholders and traded on stock exchanges. They raise capital by selling shares to the public, allowing anyone to invest in the company. This structure enables them to access larger amounts of funding for growth and expansion. These corporations are required to follow strict regulations and disclose financial information to ensure transparency. Examples of public corporations include Apple, Microsoft, and Coca-Cola. Their performance is closely monitored by investors and analysts, influencing stock prices and overall market trends.
