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 tracking error calculation excel index returns. Many portfolios are managed to a benchmark, typically an index. Some portfolios tracking error calculation example are expected to replicate, before trading and other costs, the returns of an index exactly (e.g., an index fund), while how to calculate tracking error of a portfolio 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 tracking error formula 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 ] −

How can I calculate the Annualized Tracking Error and why? How does the formula change for monthly returns.
