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

- ABN AMRO Asset Management Introduction Tracking errors are calculated to measure active portfolio risks, to set risk limits calculate tracking error from monthly returns and for risk budgeting purposes within the investment process. Practitioners have recently become concerned about the deviation between the realised (ex-post) tracking errors of their portfolios and their predicted (ex-ante) tracking https://en.wikipedia.org/wiki/Tracking_error error levels. This is not surprising, given the volatility swings in the last couple of years. The investment industry at large has criticised the accuracy of the risk forecasts that risk factor models in general provided. The general opinion is that the risk models underestimate the realised portfolio risks. We therefore believe it is important to investigate how well the ex-ante tracking error http://www.financialplaces.com/articles/managing-ex-ante-tracking-error/ predicts the ex-post tracking error and to make suggestions on how we should manage ex-ante tracking errors going forwards. In our analysis, we use the BARRA Global Equity Model (GEM) to calculate the ex ante tracking error. Definition Of Tracking Error The relative risk profile of a portfolio versus a specific benchmark is measured by the tracking error (or active risk). There are two different ways to measure the tracking error, on an ex-ante and ex-post basis.The ex-ante tracking error is a statistical measure that is defined as the forecast annualised standard deviation of the active returns of a portfolio relative to a pre-defined benchmark. An ex-ante tracking error of 2% indicates that there is a two-thirds probability that the portfolio returns will fall within +/- 2% of the benchmark return over the next year (see graph 1). Source: BARRA, Global Equity Handbook A higher ex-ante tracking error means there is a higher probability that the portfolio return will deviate from the benchmark return. It reflects the riskiness of the portfolio versus the benchmark. In general, the ex-ante tracking error is a function of the portfolio
