TSR, or Total Shareholder Return, is a financial metric used to measure the performance of an investment in a company. It combines both capital gains and dividends received over a specific period, providing a comprehensive view of how much value an investor has gained. TSR is often expressed as a percentage, making it easier to compare the performance of different investments. Investors and analysts frequently use TSR to evaluate the effectiveness of a company's management and its ability to generate returns for shareholders. By focusing on total returns rather than just stock price appreciation, TSR offers a more complete picture of an investment's success.
