their investment managers. Strange, unfamiliar terms drift through the air: Sharpe ratio, alpha, r-squared, down-market capture ratio ... You hear the term "batting average" and think you can join in, but it's quickly apparent they aren't talking baseball. There are many statistical factors that professional analysts use to assess an investment manager. They may seem confusing at first, but many of these factors can be used by non-professionals to determine the value of their own investment managers. To make calculations easier, several of these statistical measures are available in commercial software packages such as Wilshire, Zephyr, or PSN Informa. In this article, we'll go through the key statistics you need to know to assess your own managers performance. AlphaAlpha is a measure of investment performance adjusted for the risk taken. It indicates the portion of a manager's return that can attributed to the manager's skill rather than the movement of the overall market. A positive alpha implies that a manager has added value over and above the performance of the market; conversely, a negative alpha would indicate that the manager has reduced value by underperforming the market. (To learn more, read Adding Alpha Without Adding Risk.) BetaBeta measures the manager's systematic risk. It compares the return volatili
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 tracking error example an index. Some portfolios are expected to replicate, before trading and other costs, the returns of tracking error information ratio 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 http://www.investopedia.com/articles/pf/07/investment_manager_stats.asp 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 https://en.wikipedia.org/wiki/Tracking_error 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 portfolio’s active returns (one standard deviation from mean) can be e
