Information ratio is also called performance evaluation ratio. Information ratio describes the income after risk adjustment from the perspective of active management, which is different from Sharp ratio in absolute income and total risk. It represents the excess income brought by the unit's active risk. The greater the information ratio of IR =α∕ω(α is the excess return of portfolio and ω is the active risk), the higher the excess return that fund managers get from tracking errors.
