Troubleshooting Are you giving var.constraint or bench.constraint a value (or values) that correspond to the variance matrix that you are using?  Is the variance for returns or percent returns?  What is have a peek here

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 Formulas The ex-post tracking error formula is the standard deviation of the active returns, given by: T E = ω = Var ⁡ ( r p − r b ) = Read More » Latest Videos Leo Hindery on the Future of Bundles Leo Hindery on ATT, Time Warner Guides Stock Basics Economics Basics Options Basics These differences equal -1%, -2%, -1%, 5%, and 1%. http://www.envestnet.com/sites/default/files/documents/A%20Tracking%20Error%20Primer%20-%20White%20Paper.pdf

## Tracking Error Information Ratio

Ultimately, tracking error is an indicator of a manager's skill and a reflection of how actively or passively a portfolio is managed. The more a fund manager has attempted to beat his/her benchmark of reference by overweighing/underweighing selected stocks, the greater this difference will be (both negatively and positively). 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 retVolMax07H1 <- valuation(rpVolMax, xassetPrices[251:376,], returns="log") volVolMax07H1 <- apply(retVolMax07H1, 2, sd) * sqrt(252) * 100 Figure 2: Volatility realized in H1 of 2007 for the rpVolMax portfolios.

1. Checking your work predicted volatility We can check that the volatility is really being restricted by collecting the ex-ante variances for the portfolios: volCheck <- sqrt(252 * unlist(randport.eval(rpVolMax, keep='var.values'))) The volCheck

Thus, tracking error gives investors a sense of how "tight" the portfolio in question is around its benchmark or how volatile the portfolio is relative to its benchmark.

## rpTEmax <- random.portfolio(1000, priceVector, long.only=TRUE, gross=grossVal, variance=xaLWvar06EqWt, existing=curPortfol, bench.constraint=c(EqWt=.02^2/252)) There must be a name on the value given to bench.constraint so that it knows which asset to use as the benchmark.

The latter way to compute the tracking error complements the formulas below but results can vary (sometimes by a factor of 2). Examples Index funds are expected to have minimal tracking errors. Doing the example The objects: priceVector, grossVal, curPortfol that are defined in several examples, such as in  “Passive, no benchmark (minimum variance)” xaLWvar06 variance matrix from “Returns to variance matrix” example Annualised Tracking Error This is not always what the fund's investors want, and this is why tracking error is in some ways a measure of excess risk.

Ex-post tracking error is more useful for reporting performance, whereas ex-ante tracking error is generally used by portfolio managers to control risk. If a manager is realizing low average returns and has a large tracking error, it is a sign that there is something significantly wrong with that investment and that the investor Although the benchmark represents a feasible alternative to the portfolio in question, calculating tracking error does not mean the wise investor must limit comparison to just the benchmark; he or she Tracking error shows an investment's consistency versus a benchmark over a given period of time.

Several factors generally determine a portfolio's tracking error: 1. 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% 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. The volatility of the benchmark 6.

The realized volatility for all of the portfolios is significantly bigger than 12%.  However, that need not mean we have done anything wrong because 2007 is when volatility started to heat 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 A high TEV value indicates an actively managed fund (in other words, the fund manager has attempted to beat the benchmark and not simply to replicate it); on the other hand, 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
