# What is the Information Ratio?

28 Aug, 2024

Investors must understand how well a fund manager performs compared to the market. The Information Ratio helps in this assessment. This blog simplifies the Information Ratio, explaining its formula, benefits, and risks straightforwardly.

Information Ratio is a measure investors use to understand how well a fund manager performs compared to a chosen benchmark, considering the risk taken. It helps investors assess whether a manager’s skill in generating returns justifies the risk they are exposed to.

Imagine you have two mutual funds: Fund A and Fund B. Both aim to beat a particular stock market index, like the Nifty 50. The Information Ratio tells you which fund not only beat the index but did so while taking into account how risky their investments were.

A higher Information Ratio suggests that a fund manager is skilled at delivering returns above the benchmark, considering the level of risk involved.

This ratio is valuable for investors because it provides a clear picture of a fund’s performance relative to its risk, helping them make better-informed decisions about where to invest their money.

## Formula of Information Ratio

The Information Ratio is calculated using the formula:

Information Ratio = (Average Excess Return of Portfolio)/(Tracking Error of Portfolio)

Average Excess Return of Portfolio: The average return generated by the portfolio above the benchmark.

Tracking Error of Portfolio: Measures the volatility or risk of the portfolio relative to the benchmark.

## How is the Information Ratio Calculated?

To calculate the Information Ratio, follow these steps:

1. Calculate Excess Returns: Determine the portfolio’s excess returns by subtracting the benchmark’s returns from the portfolio’s returns over a specific period.
2. Calculate Tracking Error: Measure the volatility of the portfolio’s returns relative to the benchmark. This is known as the tracking error.
3. Compute Information Ratio: Divide the portfolio’s average excess return by the tracking error. The resulting ratio indicates how well the portfolio performed relative to the benchmark, considering the risk involved.

For Example:

Suppose a portfolio has an average excess return of 8% over the benchmark, and its tracking error is 10%. The Information Ratio would be 0.8 (8% divided by 10%).

This calculation helps investors assess whether the fund manager’s performance justifies the risk taken compared to a chosen benchmark. It’s a useful tool for evaluating investment managers’ skills in delivering returns adjusted for risk.

## Importance of Information Ratio

Understanding the Information Ratio is key to evaluating fund performance. Here’s why it’s so important for investors:

• Measures how effectively a fund manager generates returns relative to the risks taken.
• Provides insights into the manager’s ability to deliver consistent performance across different market conditions.

### Comparative Analysis

• Facilitates accurate comparison of funds based on risk-adjusted returns, not just absolute performance figures.
• Helps investors identify funds that outperform benchmarks while managing risks effectively.

### Transparency

• Quantifies the relationship between risk and return, enhancing transparency in investment evaluation.
• Assists in distinguishing between skillful management and excessive risk-taking behaviours.

### Decision Making

• Guides investors in allocating capital by highlighting funds with higher Information Ratios.
• Indicates superior returns per unit of risk, aligning with goals for stable and profitable investments.

### Portfolio Management

• Supports effective portfolio diversification by identifying funds with consistent risk-adjusted returns.
• Helps minimise overall portfolio risk while potentially enhancing long-term performance.

### Performance Consistency

• Assesses the consistency of a fund manager’s performance across various market cycles.
• A high Information Ratio suggests the ability to consistently deliver superior risk-adjusted returns, offering confidence in the manager’s skills.

## Risks of Information Ratio

Using the Information Ratio to evaluate investment performance has its risks. Here are some key points to keep in mind:

• Overemphasis on Short-Term Performance
• Investors may focus excessively on recent performance rather than long-term goals.
• Decisions based on short-term fluctuations can overlook broader investment strategies.
• Benchmark Selection Bias
• Choosing an inaccurate benchmark can distort the Information Ratio’s assessment.
• Comparing a fund to an unsuitable index may misrepresent its actual performance.
• Sensitivity to Market Conditions
• High market volatility can cause significant fluctuations in the Information Ratio.
• Evaluating the ratio during stable versus volatile market conditions is crucial for accurate assessment.
• Limited Scope of Risk Metrics
• Historical Performance Reliance
• Depending solely on past information ratios, they may not account for changes in market dynamics or a fund manager’s strategy.
• Future performance may differ from historical trends, requiring a cautious approach to investment decisions.

## Conclusion

Understanding Information Ratio equips investors with a valuable tool to assess fund manager performance accurately. By grasping its formula, benefits, and potential risks, investors can navigate the financial markets with greater confidence.
