The Information Ratio (IR) is a financial metric used to measure the performance of an investment, such as a mutual fund or a portfolio, relative to a benchmark index, while taking into account the risk taken to achieve that performance. It provides insight into how much excess return (alpha) an investment generates for each unit of risk (tracking error) relative to the benchmark.
