Relative Return
Relative return is a measure of the return of an investment portfolio relative to a theoretical passive reference portfolio or benchmark. In active portfolio management, the aim is to maximize the relative return (often subject to a risk constraint). In passive portfolio management, the aim is to obtain a relative return as close to zero as possible, thereby reproducing the return of the theoretical reference portfolio. When the relative return is positive, the portfolio is said to outperform the benchmark. Conversely, when the relative return is negative, the portfolio is said to underperform the benchmark. Within passive portfolio management, the absolute value of the relative return is often called the tracking error, which is confusing since the tracking error is more generally defined as the standard deviation of the relative return. Index funds are the financial products that use passively managed portfolios. Many investors use the relative return measure to measure to ...

Tracking Error
In finance, tracking error or active risk is a measure of the risk in an investment portfolio that is due to active management decisions made by the portfolio manager; it indicates how closely a portfolio follows the index to which it is benchmarked. The best measure is the standard deviation of the difference between the portfolio and index returns. Many portfolios are managed to a benchmark, typically an index. Some portfolios are expected to replicate, before trading and other costs, the returns of an index exactly (e.g., an index fund), while others are expected to ' actively manage' the portfolio by deviating slightly from the index in order to generate active returns. Tracking error is a measure of the deviation from the benchmark; the aforementioned index fund would have a tracking error close to zero, while an actively managed portfolio would normally have a higher tracking error. Thus the tracking error does not include any risk (return) that is merely a function of the mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
