Define Calculate And Interpret Tracking Error

the benchmark or index it was meant to mimic or beat. Tracking error is sometimes called active risk. There are two ways to measure tracking error. The first is to subtract the benchmark's tracking error example cumulative returns from the portfolio's returns, as follows: Returnp - Returni = Tracking
Tracking Error Interpretation
Error Where: p = portfolio i = index or benchmark However, the second way is more common, which is to tracking error information ratio calculate the standard deviation of the difference in the the portfolio and benchmark returns over time. The formula is as follows: How it works (Example): Let's assume you invest in the XYZ Company annualized tracking error mutual fund, which exists to replicate the Russell 2000 index, both in composition and in returns. If the XYZ Company mutual fund returns 5.5% in a year but the Russell 2000 (the benchmark) returns 5.0%, then using the first formula above, we would say that the XYZ Company mutual fund had a 0.5% tracking error. As time goes by, there will be more periods during

which we can compare returns. This is where the second formula becomes more useful. The consistency (or inconsistency) of the "spreads" between the portfolio's returns and the benchmark's returns is what allows analysts to try to predict the portfolio's future performance. If, for example, we knew that the portfolio's annual returns were 0.4% higher than the benchmark 67% of the time during the last five years, we would know that this would probably be the case going forward (assuming the portfolio manager made no major changes). The predictive value of these calculations gets even better when there are more data points and when the analyst accounts for how the portfolio's securities move relative to one another (this is called co-variance). Several factors generally determine a portfolio's tracking error: 1. The degree to which the portfolio and the benchmark have securities in common 2. Differences in market capitalization, timing, investment style, and other fundamental characteristics of the portfolio and the benchmark 3. Differences in the weighting of assets between the portfolio and the benchmark 4. The management fees, custodial fees, brokerage costs and other expenses affecting the portfolio that don't affect the benchmark 5. The

Tracking error is the difference between the return on a portfolio or fund, and the benchmark it is expected to mirror (or track). There are two ways to calculate the tracking error. The first is the easiest. Simply subtract the fund’s return from the return of the index it is supposed to track. For instance, a mutual fund that is pegged to the S&P http://www.investopedia.com/video/play/tracking-error/ 500 had a 7% return for the year, whereas the S&P had an 8% return. The tracking error is 1%. The second way to calculate the tracking error is more complicated, but more informative. This calculation involves taking the standard deviation of the difference in the fund’s and index’s returns over time. The formula is: Standard deviation of tracking error = 1/(n - 1) Σ(xi - yi)2 Where n is equal to the number of periods, x equals the fund’s return for each given period and y equals the benchmark’s return for each period. By using the standard deviation calculation, investors get a better idea of how the fund will perform compared to the benchmark over time. A low standard deviation means the fund tracks the benchmark fairly closely. A higher standard deviation means the fund does not track its benchmark very well. These figures indicate how well a fund is managed. Investors seeking a fund that accurately tracks their preferred index should look for funds with low tracking errors.

it indicates how closely a portfolio follows the index to which it is benchmarked. The best measure https://en.wikipedia.org/wiki/Tracking_error is the standard deviation of the difference between the portfolio and http://www.analystforum.com/forums/cfa-forums/cfa-general-discussion/9939876 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 tracking error 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 define calculate and merely a function of the market's movement. In addition to risk (return) from specific stock selection or industry and factor "bets," it can also include risk (return) from market timing decisions. Dividing portfolio active return by portfolio tracking error gives the information ratio, which is a risk adjusted performance measure. Contents 1 Definition 1.1 Formulas 1.2 Interpretation 2 Examples 3 References 4 External links Definition[edit] If tracking error is measured historically, it is called 'realized' or 'ex post' tracking error. If a model is used to predict tracking error, it is called 'ex ante' tracking error. Ex-post tracking error is more useful for reporting performance, whereas ex-ante tracking error is generally used by portfolio managers to control risk. Various types of ex-ante tracking error models exist, from simple equity models which use beta as a primary determinant to more complicated multi-factor fixed income models. In a factor model of a portfolio, the non-systematic risk (i.e., the standard deviation of the residuals) is called "tracking error" i
