Secondly, IR tells us the level of skill of a portfolio manager and how successful is the strategy deployed in an investment. Investors, market analysts, and traders pay attention to the information ratio when selecting investment instruments that will give them the highest level of return for their underlying risk Usually, high information ratios show that the return of a portfolio exceeds the return of a benchmark at a desirable level of consistency.
It also shows how much return portfolio gives compared to volatility. When calculating an information ratio, a tracking error is including using the standard deviation of the difference in returns of a portfolio and the benchmark. When there is high volatility, and less consistency, a high tracking record or standard deviation will be recorded while a low tracking record shows less volatility and higher consistency. The most important points to know about the information ratio are;.
The Sharpe ratio has similar functions as the information ratio because it helps investors understand the level of return of an investment compared to its risk. While the information ratio measures the excess returns of a portfolio above the total returns of a benchmark compared to the volatility of the returns, the Sharpe ratio measures the performance return of an investment compared to the risk-free rate of return, after adjusting for risk.
Both the information ratio and the Sharpe ratio are vital to investors and market analysts as it helps them make informed decisions. However, investors often use the IR since it compares the returns of an investment to the returns of a benchmark, considering the volatility of the returns. The fact that the information ratio measures the risk-adjustment returns of an investment which exposes it to diverse interpretations is a major drawback of the ratio.
Given that IR can be interpreted differently by many investors due to the influence of preference, investment goals, and risk tolerance levels, it might not be an accurate ratio when making investment decisions. Another argument against the information ratio is that it is better used for simple investment portfolios and not multiple funds, given that comparing multiple funds to a benchmark can give rise to complications in the ratio.

Although compared funds may be different in nature, the IR standardizes the returns by dividing the difference in their performances, known as their expected active return , by their tracking error:. To calculate IR, subtract the total of the portfolio return for a given period from the total return of the tracked benchmark index. Divide the result by the tracking error. The tracking error can be calculated by taking the standard deviation of the difference between the portfolio returns and the index returns.
For ease, calculate the standard deviation using a financial calculator or Excel. The information ratio identifies how much a fund has exceeded a benchmark. Higher information ratios indicate a desired level of consistency, whereas low information ratios indicate the opposite. Many investors use the information ratio when selecting exchange-traded funds ETFs or mutual funds based on their preferred risk profiles.
Of course, past performance is not an indicator of future results, but the IR is used to determine whether a portfolio is exceeding a benchmark index fund. The tracking error is often calculated by using the standard deviation of the difference in returns between a portfolio and the benchmark index. Standard deviation helps to measure the level of risk or volatility associated with an investment.
A high standard deviation means there is more volatility and less consistency or predictability. The information ratio helps to determine by how much and how often a portfolio trades in excess of its benchmark but factors in the risk that comes with achieving the excess returns. Some investors are paying 0. It's important to determine whether the fund is beating a similar benchmark index on a consistent basis. The IR calculation can help provide a quantitative result of how well your fund is being managed.
Like the information ratio, the Sharpe ratio is an indicator of risk-adjusted returns. However, the Sharpe ratio is calculated as the difference between an asset's return and the risk-free rate of return divided by the standard deviation of the asset's returns.
The risk-free rate of return would be consistent with the rate of return from a risk-free investment like a U. Treasury security. The IR also measures the consistency of an investment's performance. However, the Sharpe ratio measures how much an investment portfolio outperformed the risk-free rate of return on a risk-adjusted basis.
Both financial metrics have their usefulness but the index comparison makes the IR more appealing to investors since index funds are typically the benchmark used in comparing investment performance and the market return is usually higher than the risk-free return. Any ratio that measures risk-adjusted returns can have varied interpretations depending on the investor.
Each investor has different risk tolerance levels and depending on factors such as age, financial situation, and income might have different investment goals. As a result, the IR is interpreted differently by each investor depending on their needs, goals, and risk tolerance levels.
Also, comparing multiple funds against a benchmark is difficult to interpret because the funds might have different securities, asset allocations for each sector, and entry points in their investments. As with any single financial ratio, it's best to look at additional types of ratios and other financial metrics to make a more comprehensive and informed investment decision.
A high IR can be achieved by having a high rate of return in the portfolio as compared to a lower return in the index as well as a low tracking error. A high ratio means that, on a risk-adjusted basis, a manager has produced better returns consistently compared to the benchmark index. For example, say you're comparing two different fund managers:.
Fund Manager A's IR equals 1.
Information ratios of 1. Nonetheless, the information ratio ignores the influence of leverage on portfolio returns. Thus, even if a portfolio produces better risk-adjusted returns than the index, the information ratio can come back negative.
Calculate alpha excess return over benchmark by taking the return of the portfolio and subtracting the product of beta and the return of the benchmark. Ensure that the time periods are compatible. If the value in step four is for monthly returns, then the same should be true in step five.
To annualize a value, simply take it to the logical power required. If monthly, take the figure to the power of twelve. If quarterly, to the power of four, and so forth. The information ratio measures the excess return of a portfolio adjusted for its risk. The main problem associated with the information ratio is that it fails to take into account portfolios that do better per unit of risk if their trading results are below the benchmark. In these cases, traders and portfolio managers are better off using the geometric information ratio.

Top-quartile investment managers typically achieve annualized information ratios of about one-half. Some hedge funds use Information ratio as a metric for calculating a performance fee. The information ratio is often annualized. While it is then common for the numerator to be calculated as the arithmetic difference between the annualized portfolio return and the annualized benchmark return, this is an approximation because the annualization of an arithmetic difference between terms is not the arithmetic difference of the annualized terms.
One of the main criticisms of the Information Ratio is that it considers arithmetic returns rather than geometric returns and ignores leverage. This can lead to the Information Ratio calculated for a manager being negative when the manager produces alpha to the benchmark and vice versa. A better measure of the alpha produced by the manager is the Geometric Information Ratio. From Wikipedia, the free encyclopedia. Grinold and Ronald N. Journal of Risk and Financial Management.

The information ratio (IR) is a measurement of portfolio returns beyond the returns of a benchmark, usually an index, compared to the volatility of those. The information ratio, also known as appraisal ratio, measures and compares the active return of an investment compared to a benchmark index relative to the volatility of the active return. It is defined as the active return divided by the. The information ratio measures the risk-adjusted returns of a financial asset or portfolio relative to a certain benchmark. This ratio aims to show excess.
