The information ratio acts as a fundamental gauge that assesses the performance of a portfolio that is actively managed in relation to its benchmark. Thus, it gauges consistent act of surplus earnings (earnings beyond the difference between the benchmark and returns) achieved by a portfolio during high risks.

​
Importance of Information Ratio

Performance Measurement: This tells how efficiently each unit of risk turns into excess returns over the market benchmark for a manager.

Risk-Adjusted Performance: In contrast to absolute measures, IR views performance from different angles taking into account risk required for achieving these results.

Consistency Indicator: Higher IR implies that even though excess returns remain volatile, they are more stable than before comparing with benchmarks’ rates.

Interpretation of Information Ratio

A positive IR indicates value addition by a portfolio manager who outperforms his/her bench mark.

A higher information ratio indicates better performance as it means that greater risk was taken for every additional unit of return.
An information ratio less than one is considered negative, indicating underperformance in relation to the market portfolio.

Practitioners’ Guide to Information Ratio

Investors and analysts rely on IR to distinguish between different portfolio managers or investment strategies. This helps them identify those fund managers who have been able to consistently add value and manage risk in their portfolios.

Limitations of Information Ratio

Dependence on Benchmark: The choice of benchmark can greatly affect the IR value. Using an inappropriate benchmark may lead to misinterpretations of performance.

Short-Term Volatility: Short-term movements in a fund’s performance can cause an information ratio to vary significantly from year to year, often not reflecting its long-term historical record.

Focus on Relative Performance: An investor’s focus should be on absolute returns which refer to levels of returns provided by investments rather than relative performances as measured by IR.

Conclusion

The Information Ratio is an important gauge of active management efficiency because it incorporates both the risks and rewards associated with achieving such results; this allows investors to assess how well skilled portfolio managers are at producing superior performances compared against a yardstick while maintaining relatively consistent high rates of return.
