An analyst examined the past performance of two commodity funds that follow the S&P500 as a benchmark. The analyst collected monthly return data and utilized the Information Ratio (IR) to evaluate which fund generated greater returns more effectively. The analyst then presented the results as follows:
| Fund A | Fund B | Benchmark | |
|---|---|---|---|
| Average monthly return | 2.63% | 2.54% | 2.35% |
| Average excess return | 0.28% | 0.19% | 0.00% |
| Standard deviation of returns | 0.51% | 0.48% | 0.45% |
| Tracking error | 0.56% | 0.53% | 0.00% |
What is the Information Ratio (IR) for each fund?
A
Fund A Information Ratio (IR) = 0.54, Fund B Information Ratio (IR) = 0.39
B
Fund A Information Ratio (IR) = 0.50, Fund B Information Ratio (IR) = 0.35
C
Fund A Information Ratio (IR) = 0.46, Fund B Information Ratio (IR) = 0.47
D
Fund A Information Ratio (IR) = 0.91, Fund B Information Ratio (IR) = 0.90
