The IC is not to be confused with the Information Ratio (IR). Information ratio (IR), the ratio of average excess return to active risk, is an important performance measure for active investment management. If an analyst's predictions were only half of the time right, then: IC=(2×0.5)−1=0.0\begin{aligned} &\text{IC} = (2 \times 0.5) - 1 = 0.0 \\ \end{aligned}IC=(2×0.5)−1=0.0.
