What is a good information coefficient? Explaining the Information Coefficient An IC of +1.0 indicates a perfect linear relationship between predicted and actual returns, while an IC of 0.0 indicates no linear relationship. An information coefficient (IC) score near +1.0 indicates that the analyst has great skill in forecasting.
What is the information coefficient?
The information coefficient is similar to correlation in that it can be seen to measure the linear relationship between two random variables, e.g. predicted stock returns and the actualized returns.
What does the sign of the coefficient tell you?
The sign of the coefficient tells you the direction of the relationship: a positive value means the variables change together in the same direction, while a negative value means they change together in opposite directions. The absolute value of a number is equal to the number without its sign.
What does a coefficient of 0 mean in economics?
The coefficient can take any values between 0 to 1 (or 0% to 100%). A coefficient of zero indicates a perfectly equal distribution of income or wealthGross Domestic Product (GDP)Gross domestic product (GDP) is a standard measure of a country’s economic health and an indicator of its standard of living.
What is the coefficient of determination?
The coefficient of determination is a measure used in statistical analysis to assess how well a model explains and predicts future outcomes. A linear relationship (or linear association) is a statistical term used to describe the directly proportional relationship between a variable and a constant.
What is IC in investing?
Information coefficient (IC) is a widely used metric for measuring investment managers' skills in selecting stocks. Statistically, this metric describes the correlation between the actual and predicted stock returns that the managers considered in the investment management process.
What is IC in statistics?
Information coefficient (IC) is one of the most commonly used statistics in quantitative financial analysis that is usually defined as the correlation coefficient between a variable's predicted and actual values.
Is the information coefficient really a random normally distributed variable?

What is IC report?
An Intellectual Capital Report (IC Report) is a voluntary supplement to a company's financial report that provides detailed information about the intellectual assets of the organization. It helps in improving the organization's internal processes for managing its intangible resources.
What is IC in research?
IC. Informed Consent. Medical, Medical Research, Education.
What is a high mutual information score?
High mutual information indicates a large reduction in uncertainty; low mutual information indicates a small reduction; and zero mutual information between two random variables means the variables are independent.
How can you tell if data is normally distributed?
You can test the hypothesis that your data were sampled from a Normal (Gaussian) distribution visually (with QQ-plots and histograms) or statistically (with tests such as D'Agostino-Pearson and Kolmogorov-Smirnov).
How do you know if data is normally distributed with mean and standard deviation?
In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean. It must also adhere to the empirical rule that indicates the percentage of the data set that falls within (plus or minus) 1, 2 and 3 standard deviations of the mean.
What is an acceptable information ratio?
Generally speaking, an information ratio in the 0.40-0.60 range is considered quite good. Information ratios of 1.00 for long periods of time are rare. Typical values for information ratios vary by asset class.
What is a bad information ratio?
If the information ratio of a mutual fund is negative, it indicates that the mutual fund manager was unable to produce any excess returns at all. An information ratio of less than 0.4 means that the mutual fund could not produce excess returns for a sufficiently long time and the fund may not be a good investment.
Is a higher information ratio better?
What Is a Good Number? The higher the information ratio, the better. If the information ratio is less than zero, it means the active manager failed on the first objective of outperforming the benchmark. Of all the performance statistics, the information ratio is one of the most difficult hurdles to clear.
Why is the coefficient of variation considered to be better?
In most fields, lower values for the coefficient of variation are considered better because it means there is less variability around the mean.
What is coefficient of variation?
A coefficient of variation, often abbreviated CV, is a way to measure how spread out values are in a dataset relative to the mean.
What does a CV of 1.5 mean?
A CV of 1 means the standard deviation is equal to the mean. A CV of 1.5 means the standard deviation is 1.5 times larger than the mean. The higher the coefficient of variation, the higher the standard deviation relative to the mean.
Why is information ratio important?
The information ratio is primarily used as a performance measure by fund managers. In addition, it is frequently used to compare the skills and abilities of fund managers with similar investment strategies .
What is the rate of return?
Rate of Return The Rate of Return (ROR) is the gain or loss of an investment over a period of time copmared to the initial cost of the investment expressed as a percentage.
What is Dow Jones Industrial Average?
Dow Jones Industrial Average (DJIA) The Dow Jones Industrial Average (DJIA), also referred to as "Dow Jones” or "the Dow", is one of the most widely-recognized stock market indices. . This ratio aims to show excess returns relative to the benchmark, as well as the consistency in generating the excess returns.
What does a correlation coefficient tell you?
Correlation coefficients summarize data and help you compare results between studies.
Using a correlation coefficient
In correlational research, you investigate whether changes in one variable are associated with changes in other variables.
Interpreting a correlation coefficient
The value of the correlation coefficient always ranges between 1 and -1, and you treat it as a general indicator of the strength of the relationship between variables.
Visualizing linear correlations
The correlation coefficient tells you how closely your data fit on a line. If you have a linear relationship, you’ll draw a straight line of best fit that takes all of your data points into account on a scatter plot.
Types of correlation coefficients
You can choose from many different correlation coefficients based on the linearity of the relationship, the level of measurement of your variables, and the distribution of your data.
Other coefficients
The correlation coefficient is related to two other coefficients, and these give you more information about the relationship between variables.
Frequently asked questions about correlation coefficients
A correlation reflects the strength and/or direction of the association between two or more variables.
What are the drawbacks of the coefficient?
One of the drawbacks of the coefficient is that it does not take into consideration the structural changes in a population. Such changes can significantly influence the economic inequality in a population. Generally, the situation arises because young people tend to earn less relative to older people.
What does a coefficient of zero mean?
The coefficient can take any values between 0 to 1 (or 0% to 100%). A coefficient of zero indicates a perfectly equal distribution of income or wealth. Gross Domestic Product (GDP) Gross domestic product (GDP) is a standard measure of a country’s economic health and an indicator of its standard of living.
What is Gini coefficient?
The Gini coefficient (Gini index or Gini ratio) is a statistical measure of economic inequality in a population. The coefficient measures the dispersion of income. Remuneration Remuneration is any type of compensation or payment that an individual or employee receives as payment for their services or the work that they do for an organization ...
Is the Gini coefficient an absolute measure of wealth?
Please note that the Gini coefficient is not an absolute measure of a country’s income or wealth. The coefficient only measures the dispersion of income or wealth within a population.
Does the Gini coefficient depend on the economy?
The calculation of the Gini coefficient does not depend on how large the economy is, how it is measured, or how wealthy a country is. For example, both rich and poor countries may show the same coefficient due to similar income distribution.
Is the Gini coefficient valid?
The validity of Gini coefficient calculations can be dependent on the size of a sample. For example, small countries or countries with less economic diversity frequently tend to show low coefficients, while large economically diverse countries usually demonstrate high coefficients.

Explaining The Information Coefficient
- The information coefficient describes the correlation between predicted and actual stock returns, sometimes used to measure the contribution of a financial analyst. An IC of +1.0 indicates a perfect linear relationship between predicted and actual returns, while an IC of 0.0 indicates no linear relationship. An IC of -1.0 indicates that the analyst always fails at making a correct predic…
Example of The Information Coefficient
- As a hypothetical example, if an investment analyst made two predictions and got two right, the information coefficient would be: IC=(2×1.0)−1=+1.0\begin{aligned} &\text{IC} = (2 \times 1.0) - 1 = +1.0 \\ \end{aligned}IC=(2×1.0)−1=+1.0 If an analyst's predictions were only half of the time right, then: IC=(2×0.5)−1=0.0\begin{aligned} &\text{IC} = (2 \times 0.5) - 1 = 0.0 \\ \end{aligned}I…
Limitations of The Information Coefficient
- The IC is only meaningful for an analyst who makes a large number of predictions. This is because if there only a small number of predictions, random chance may explain a great deal of the results. So if there are only two predictions made and both are right the information coefficient is +1.0. If, however, the IC is till at or close to +1.0 after several dozen predictions hav…
