Information Ratio Formula

by / ⠀ / March 21, 2024

Definition

The Information Ratio Formula is a financial measurement used to evaluate portfolio returns and to measure the consistency of a manager’s returns relative to a benchmark. It is calculated by subtracting the benchmark’s return from the portfolio’s return (excess return) and dividing that by the tracking error (volatility of the excess return). A higher Information Ratio suggests a superior risk-adjusted return of a portfolio.

Key Takeaways

  1. The Information Ratio Formula is used to measure the potential return of a portfolio or program, taking into account the amount of risk associated with it. It does so by comparing it to a benchmark index.
  2. The formula is calculated by subtracting the benchmark return from the portfolio return, the result is then divided by the tracking error. Essentially, the higher the information ratio, the better the risk-adjusted return.
  3. While the information ratio provides useful data, it should not be solely relied upon for making investment decisions. It’s simply one tool out of many that can be used for portfolio management and investment analysis.

Importance

The Information Ratio Formula is vital in the field of finance because it serves as a measurement tool that evaluates a portfolio’s expected return beyond a benchmark, relative to the unpredictability of those returns.

This ratio reflects the risk-adjusted performance of a portfolio and is commonly used by fund managers to assess their performance as compared to the market index or benchmark portfolio.

It allows investors to quantify the excess return they can anticipate for assuming extra risk as they strive to outperform the benchmark.

Therefore, it is a valuable metric as it aids in determining if the added risk taken by portfolio managers to achieve superior returns is justified, thereby informing investment decisions.

Explanation

The Information Ratio Formula serves as a fundamental tool used in financial analysis to evaluate the expected returns of a portfolio in relation to its risk-adjusted performance. Its primary purpose is to measure the active return of an investment portfolio against the tracking error, which is the standard deviation of the active return.

This helps portfolio managers gauge the performance of the portfolio they managed by identifying the degree to which it outperforms or underperforms the benchmark index set, after adjusting for the risk taken. The applications of the Information Ratio formula are extensive and valuable.

It is commonly used by portfolio managers, investors, and financial analysts to make calculative and strategic decisions. The ratio provides an indicative assessment of the risk-reward trade-off, helps in optimizing the portfolio, and aids in assessing the skill of the manager.

A higher Information Ratio implies a better risk-adjusted return of the portfolio, which proves beneficial from an investor’s viewpoint.

Examples of Information Ratio Formula

Investment Portfolio Evaluation: Let’s say an investment manager wants to evaluate their portfolio’s performance. The manager has a portfolio that has produced a return of 13% over the last year, while the benchmark index has produced a return of 10%. The portfolio’s standard deviation of excess return over the benchmark index is 7%. The manager can use the Information Ratio to assess the portfolio’s performance relative to the benchmark index. In this case, the Information Ratio = (13% – 10%)/7% =This result means the manager is generating a return of43 for every unit of risk taken over the benchmark, which is a relatively high value, indicating strong performance by the manager.

Comparing Fund Managers: Two fund managers, A and B, are competing for the same job. Manager A has an information ratio of2, while Manager B has an information ratio ofThe potential employer can use these ratios to compare how efficiently each manager can generate return above the benchmark per unit of risk. Here, manager A seems to be the more effective at generating more return for a given level of risk than Manager B.

Evaluating Investment Strategies: An asset management company tries two different investment strategies over a year. Strategy 1 generates an average return of 15% with a tracking error of 10% while Strategy 2 gives an average return of 12% with a tracking error of 8%. The company calculates the Information Ratio for each strategy to help decide which one is better. In this case, the Information Ratio for Strategy 1 would be (15%-10%)/10% =5, and for Strategy 2 it would be (12%-10%)/8% =Thus, according to the Information Ratio, Strategy 1 performed better than Strategy 2 with respect to the benchmark, despite the higher tracking error.

Frequently Asked Questions: Information Ratio Formula

1. What is the Information Ratio Formula?

The Information Ratio formula is a measurement that helps to assess the risk-adjusted performance of an investment portfolio. It’s calculated by subtracting the return of a benchmark from the return of a portfolio and dividing by the tracking error.

2. How is the Information Ratio Formula calculated?

The Information Ratio is calculated by subtracting the return of the benchmark from the return of the portfolio and then dividing the result by the tracking error. Mathematically, it’s represented as IR = (Rp – Rb) / TE where Rp is the return of the portfolio, Rb is the return of the benchmark, and TE is the tracking error.

3. What does a high value in the Information Ratio Formula mean?

A higher value of the Information Ratio suggests a superior risk-adjusted return. It means that the manager is efficiently utilizing the tracking error for generating excess returns.

4. How important is the Information Ratio Formula in finance?

The Information Ratio is critical in finance because it helps determine whether a portfolio’s risk management strategies are generating favorable returns. It’s particularly essential for active investors as they seek to create portfolios that offer higher returns compared to a particular benchmark.

5. Can the Information Ratio be Negative?

Yes, the Information Ratio can be negative. A negative Information Ratio means that the portfolio is underperforming compared to the benchmark index.
