Annualized Standard Deviation

Like R-Squared, Tracking Error is calculated using the common date range of the benchmark and the weighted portfolio

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 how to calculate tracking error in excel is to subtract the benchmark's cumulative returns from the portfolio's returns, as
Tracking Error Calculation Example
follows: Returnp - Returni = Tracking Error Where: p = portfolio i = index or benchmark However, the second annualized tracking error formula way is more common, which is to calculate the standard deviation of the difference in the the portfolio and benchmark returns over time. The formula is as follows: How it http://www.styleadvisor.com/content/tracking-error works (Example): Let's assume you invest in the XYZ Company 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 http://www.investinganswers.com/financial-dictionary/mutual-funds-etfs/tracking-error-4970 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 weightin
standard deviation of the differences between the return on the portfolio and the return on the benchmark; the standard deviation of the excess returns: σ2 = 1/(n - 1) Σ(xi - yi)2 Where σ is the tracking error n is the number http://moneyterms.co.uk/tracking-error/ of periods over which it is measured x is the percentage return on the portfolio in period i y is the percentage return on the benchmark Some sources claim that the average error should be subtracted from right side of the equations above. That would give us the standard deviation of the tracking error from the tracking error over time. The formula given here appears preferable as it is a measure of deviation from the benchmark itself. In order tracking error to make the tracking error comparable it should be annualised. In order to do the right right of the equation should be multiplied by the number of periods in an year. Equivalents σ multiplied by the root of the number of periods in an year. So if the error is based on monthly returns, it should be multiplied by root 12 to annualise. Tracking error may be calculated from historical data (as above) or estimated for future returns. The former annualized tracking error is called ex-post tracking error, and the latter ex-ante (standard terminology for statistics). The causes of tracking error For an actively managed fund tracking error is a measure of how actively managed it is. A closet tracker will have a low tracking error, a very actively managed fund a high tracking error. An index tracker has two different causes of tracking error: trading and management costs, the differences in the composition of the portfolio and the benchmark. The second of these is a direct result of the need to minimise the first. The simplest way to construct a tracker would be to simply hold every security in an index in proportion to its weighting in the index. The problem with this is that it increases trading costs as it involves holding a large number of securities. In order to control trading costs, tracker funds hold a selection of securities that is statistically likely to replicate the performance of the index. This requires statistical analysis to construct the portfolio that will most accurately track the index at the lowest cost. This is why tracker funds are run by quants. A portfolio that is a selected sample of the index will clearly not perform exactly as the index does. It should, however, perform very closely in like with the index. In addition to the costs of actually trading the portfolio, the fees charged by fund managers also reduce th
