The optimization … WebA geometric sequence is a sequence of numbers in which each term is obtained by multiplying the previous term by a fixed number. It is represented by the formula a_n = a_1 * r^ (n-1), where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and r is the common ratio. The common ratio is obtained by dividing the current ...

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 … See more The information ratio measures and compares the active return of an investment (e.g., a security or portfolio) compared to a benchmark index relative to the volatility of the active return (also known as active risk or benchmark … See more 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 … See more Top-quartile investment managers typically achieve annualized information ratios of about one-half.
