The Frankfurt Bond Market, 1988. A bond index or bond market index is a method of measuring the investment performance and characteristics of the bond market.There are numerous indices of differing construction that are designed to measure the aggregate bond market and its various sectors (government, municipal, corporate, etc.)
To begin, define to be: = () where is the vector of active weights for each asset relative to the benchmark index and is the covariance matrix for the assets in the index. While creating an index fund could involve holding all N {\displaystyle N} investable assets in the index, it is sometimes better practice to only invest in a subset K ...
Negative cashflows are treated as contributions. On the first period, a $100 call in the fund is matched by a $100 investment into the index. On the second period, the $100 index investment is now worth $105, to which is added $50 of new investment. A positive cashflow is treated by decreasing the index investment by the same value.
The ex-post Sharpe ratio uses the same equation as the one above but with realized returns of the asset and benchmark rather than expected returns; see the second example below. The information ratio is a generalization of the Sharpe ratio that uses as benchmark some other, typically risky index rather than using risk-free returns.
According to his book Pension Funds: Measuring Investment Performance, [1] "The method selected to measure return on investment is similar to the one described by Hilary L. Seal in Trust and Estate magazine. This measure is used by most insurance companies and by the SEC in compiling return on investment in its Pension Bulletins. [4]
The information ratio is similar to the Sharpe ratio, the main difference being that the Sharpe ratio uses a risk-free return as benchmark (such as a U.S. Treasury security) whereas the information ratio uses a risky index as benchmark (such as the S&P500). The Sharpe ratio is useful for an attribution of the absolute returns of a portfolio ...
Performance attribution, or investment performance attribution is a set of techniques that performance analysts use to explain why a portfolio's performance differed from the benchmark. This difference between the portfolio return and the benchmark return is known as the active return .
The following is an example of a typical benchmarking methodology: Identify problem areas: Because benchmarking can be applied to any business process or function, a range of research techniques may be required.
