Mastering the Information Ratio Formula: A Step-by-Step Guide
Understanding financial ratios is crucial for all investors and stakeholders in the finance sector. It is no doubt that the use of the Information Ratio Formula is essential in assessing a portfolio’s performance and making informed decisions on investments. It allows investors to measure the returns on their investment relative to the risk involved, giving them a clear picture of the profitability of their portfolio. In this article, we aim to give you a step-by-step guide on mastering the Information Ratio Formula.
What is the Information Ratio Formula?
The Information Ratio Formula is a financial ratio that measures the risk-adjusted return on a portfolio. It divides the excess return of a portfolio by the tracking error, where excess return is the return of the portfolio minus the benchmark return, and the tracking error is the standard deviation of the portfolio’s excess return.
Why is the Information Ratio Formula important?
The Information Ratio Formula is essential because it helps investors to determine whether a portfolio is performing well or not. It is a critical tool for performance evaluation and is widely used in the finance sector. The Information Ratio Formula aids investors in identifying risk-adjusted returns, allowing them to make sound decisions on investments.
How to Calculate the Information Ratio Formula
Calculating the Information Ratio Formula is relatively straightforward. Here are the steps:
Step 1: Calculate the excess return of the portfolio. Subtract the benchmark return from the portfolio return.
Excess Return = Portfolio Return – Benchmark Return
Step 2: Calculate the standard deviation of the excess return. This is also known as the tracking error.
Tracking Error = Standard deviation of the Excess Return
Step 3: Divide the excess return by the tracking error to get the Information Ratio.
Information Ratio = Excess Return / Tracking Error
Examples of Using the Information Ratio Formula
Let’s take a look at some examples to help illustrate the use of the Information Ratio Formula.
Example 1: Suppose an investor has a portfolio that returned 11% in a year, while the benchmark returned 8%. The portfolio’s standard deviation of the excess return was 2.5%. The Information Ratio would be:
Excess Return = 11% – 8% = 3%
Tracking Error = 2.5%
Information Ratio = 3%/2.5% = 1.2
A positive Information Ratio indicates that the portfolio has earned a higher return over the benchmark, taking into account the risk involved.
Example 2: Suppose another investor has a portfolio that returned 10% in a year, with the benchmark returning 11%. The portfolio’s standard deviation of the excess return was 5%. The Information Ratio would be:
Excess Return = 10% – 11% = -1%
Tracking Error = 5%
Information Ratio = -1%/5% = -0.2
A negative Information Ratio indicates that the portfolio has underperformed compared to the benchmark, taking into account the risk involved.
Conclusion
Mastering the Information Ratio Formula is essential for investors and stakeholders in the finance sector. It is a critical tool for performance evaluation and helps determine risk-adjusted returns, allowing them to make informed decisions on investments. By following the steps we have outlined in this article, you can calculate the Information Ratio Formula with ease. Remember, a positive Information Ratio indicates a higher return relative to the risk involved, while a negative Information Ratio indicates underperformance.
