What is a 'Tracking Error' Tracking error is the divergence between the price behavior of a position or a portfolio and the price behavior of a benchmark. This is often in the context of a hedge or mutual fund that did not work as effectively as intended, creating an unexpected profit or loss instead.Tracking error is reported as a standard deviation percentage difference, which reports the difference between the return an investor tracking error formula receives and that of the benchmark he was attempting to imitate. BREAKING DOWN 'Tracking Error' Since portfolio risk is often measured against a benchmark, tracking error is a commonly used metric to gauge how well an investment is performing. Tracking error shows an investment's consistency versus a benchmark over a given period of time. Even portfolios that are perfectly indexed against a benchmark behave differently than the benchmark, even though this difference on a day-to-day, quarter-to-quarter or year-to-year basis may be ever so slight. Tracking error is used to quantify this difference.Calculation of Tracking ErrorTracking error is the standard deviation of the difference between the returns of an investment and its benchmark. Given a sequence of returns for an investment or portfolio and its benchmark, tracking error is calculated as follows:Tracking Error = Standard Deviation of (P - B).For example, assume that there is a large cap mutual fund that is benchmarked to the Standard and Poor's (S&P) 500 index. Next, assume that the mutual fund and the index realized the follow returns over a given five-year period:Mutual Fund: 11%, 3%, 12%, 14% and 8%.S&P 500 index: 12%, 5%, 13%, 9% and 7%.Given this data, the series of differences is then (11% - 12%), (3% - 5%), (12% - 13%), (14% - 9%) and (8% - 7%). These differences equal -1%, -2%, -1%, 5%, and 1%. The standard deviation of this series of differences, the tracking error, is 2.79%.Interpretatio

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 500 had a 7% return for the year, http://www.investopedia.com/video/play/tracking-error/ 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. View All More Videos No results found.

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 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" in the investment field. The latter way to compute the tracking error complements the formulas below but results can vary (sometimes by a factor of 2). Formulas[edit] The ex-post tracking error formula is the standard deviation of the active returns, given by: T E = ω = Var ( r p − r b ) = E [ ( r p − r b ) 2 ] − ( E [ r p − r b ] ) 2 {\displaystyle TE=\omega ={\sqrt {\operatorname {Var} (r_{p}-r_{b})}}={\sqrt {{E}[(r_{p}-r_{b})^{2}]-({E}[r_{p}-r_{b}])^{2}}}} where rp−rb is the active return, i.e., the difference between the portfolio return and the benchmark return. Interpretation[edit] An active risk of x per cent would mean that approximately 2/3 of the portfolioâ
