Equity is the ownership stake in a company, representing the value of the company’s assets after subtracting its liabilities. It is the amount owned by shareholders or owners and reflects the difference between the company’s total assets and its total liabilities. In the context of stocks, equity represents the value of a shareholder's ownership in the company. For individuals or households, equity can refer to the ownership value in real estate, i.e., the property value minus any mortgage or other liabilities.
