## How do you calculate annual tracking error?

Tracking error is calculated by **taking the square root of the average of the squared deviations between the investment’s returns and the benchmark’s returns**, then multiplying the result by the square root of the scale of the returns.

## How do you calculate tracking error in index funds?

Mathematically, tracking error is **the annualized standard deviation of the tracking difference of an Index Fund**. In the above case, the tracking error of the Index Fund is equal to the standard deviation of the tracking difference over the 5 year period which is 2.5%.

## Is tracking error a percentage?

Tracking error is formally defined as the standard deviation of the difference between the returns of the portfolio and the returns of the benchmark—or the dispersion of the excess portfolio returns compared with its benchmark. It’s typically expressed both as an annualized number and **as a percentage**.

## What is a good tracking error number?

Theoretically, an index fund should have a tracking **error of zero relative** to its benchmark. Enhanced index funds typically have tracking errors in the 1%-2% range. Most traditional active managers have tracking errors around 4%-7%.

## What is predicted tracking error?

## What is ETF tracking difference?

Tracking difference is **the discrepancy between ETF performance and index performance**. Tracking difference is rarely nil: The ETF usually trails its index. That’s because a number of factors prevent the ETF from perfectly mimicking its index.

## Is tracking error the same as Alpha?

Alpha is the average active return over a time period. Since backward-looking tracking error measures the standard deviation of a portfolio’s active return, it **is different from alpha**. A portfolio does not have backward-looking tracking error simply because of outperformance or underperformance.
