The term “tracking error” is frequently used in the finance and investment industry to assess a portfolio’s performance. It is a gauge of how closely an investment portfolio’s returns resemble those of a benchmark index. In portfolio management, tracking error is a crucial metric since it sheds light on the degree of risk attached to the portfolio & the efficacy of the manager’s investment strategy.
Key Takeaways
- Tracking error measures the deviation of a portfolio’s returns from its benchmark’s returns.
- Benchmark and portfolio returns are the two main components of tracking error.
- The basic formula for tracking error is the standard deviation of the difference between portfolio and benchmark returns.
- A higher tracking error indicates greater deviation from the benchmark, but it may not necessarily mean poor performance.
- Common pitfalls in tracking error calculation include using inappropriate benchmarks and not accounting for fees and expenses.
As the standard deviation of the difference between the portfolio’s returns and the benchmark’s returns, tracking error is defined. It gauges how volatile the portfolio’s excess returns are in comparison to the benchmark. The portfolio follows the benchmark closely if the tracking error is low, but it deviates significantly from the benchmark if the tracking error is high. The ability of tracking error to give fund managers and investors important information about the risk & performance of a portfolio makes it important.
Investors can evaluate a portfolio manager’s ability to implement their investment strategy and produce returns that are benchmark-consistent by looking at tracking error. A high tracking error is indicative of a higher level of risk, so it also aids investors in understanding the risk associated with the portfolio. It’s critical to first comprehend the benchmark & portfolio returns that make up tracking error in order to fully comprehend tracking error. Benchmark returns are the results of a particular benchmark index, like the Dow Jones Industrial Average or the SandP 500. An industry or market’s overall performance is reflected in these benchmark indices.
The performance of a portfolio is frequently assessed using benchmark returns as a point of reference. Conversely, portfolio returns are the profits that come from a particular set of assets. The portfolio manager made these returns as a result of his or her investments. A portfolio manager’s objective is to produce returns that surpass the benchmark.
When calculating tracking error, the relationship between benchmark and portfolio returns is essential. The difference between the returns on the portfolio and the benchmark returns is used to compute the tracking error. Whereas a negative tracking error implies underperformance, a positive tracking error shows that the portfolio has outperformed the benchmark. Finding the standard deviation of the difference between the portfolio returns and the benchmark returns is the first step in calculating tracking error.
This formula can be found here: Tracking Error = Standard Deviation (Portfolio Returns – Benchmark Returns). The portfolio’s risk is indicated by the standard deviation, which calculates the dispersion or volatility of the returns. The ex-post, ex-ante, and rolling window methods are some of the ways to calculate tracking error. By periodically updating the portfolio returns & benchmark returns, the rolling window method computes tracking error over a predetermined time frame, like a year. Whereas the ex-ante approach uses expected returns to estimate tracking error, the ex-post method uses historical data to calculate tracking error.
It is essential to interpret tracking error results in order to comprehend a portfolio’s risk and performance. A low tracking error indicates that the portfolio follows the benchmark closely, which is a sign that the portfolio manager is following their investment plan to the letter. However, a high tracking error suggests that the portfolio manager is either taking on more risk or not putting their strategy into practice because it shows that the portfolio deviates significantly from the benchmark. Based on the investor’s risk tolerance and investment goals, tracking error results can have varying degrees of importance. A low tracking error is ideal for investors who want to closely mimic the returns of a benchmark.
It shows that the portfolio is producing returns that are in line with the market and tracking the benchmark with effectiveness. In contrast, a high tracking error might be acceptable to investors who are trying to beat the benchmark. In an effort to produce larger returns, it implies that the portfolio manager is actively trading & departing from the benchmark. In this scenario, the investor should determine if the possibility of higher returns outweighs the additional risk brought on by the high tracking error. When calculating and interpreting tracking error, investors & fund managers should be aware of some common pitfalls, even though tracking error is a useful metric for assessing portfolio performance. A frequent error in tracking error computation is the use of unsuitable benchmark returns.
A benchmark that accurately reflects the asset class & investment strategy of the portfolio should be chosen. The performance of the portfolio may be misinterpreted and tracking error results may be erroneous if the wrong benchmark is used. A frequent mistake is to gauge portfolio performance only by tracking error.
Tracking error should be used to provide a thorough evaluation of the portfolio’s performance along with other performance measures like alpha and Sharpe ratio. It is possible to miss other crucial elements that affect the performance of the portfolio if you only consider tracking error. Another frequent mistake is misinterpreting the results of tracking errors. A high tracking error does not always signify subpar work or undue risk.
It could just be an indication of the active investment approach and benchmark divergence of a portfolio manager. When analyzing tracking error results, it’s critical to take the investor’s risk tolerance & investment objectives into account. There are various benefits to using tracking error to assess portfolio performance. It offers a numerical indicator of how closely the portfolio follows the benchmark, to start. In doing so, investors are able to evaluate the degree of risk attached to the portfolio as well as the efficacy of the portfolio manager’s investment approach.
Comparing the performance of various portfolios or portfolio managers can be done by using tracking error, secondly. It offers a standardized measurement that makes comparisons relevant. But, employing tracking error as a performance metric has certain drawbacks as well. First off, tracking error doesn’t reveal anything regarding the direction of the departure from the reference. All that is measured is the excess returns’ volatility.
Consequently, both underperformance and outperformance may contribute to a positive tracking error. Secondly, tracking error does not account for the degree of departure from the benchmark. The performance of the portfolio may be significantly impacted by a large deviation, but it may be negligibly affected by a small one. Comparing tracking error to other performance metrics, like alpha & Sharpe ratio, is a common practice in portfolio performance evaluation.
Different insights into the performance & risk of a portfolio are offered by each of these metrics. After accounting for the risk-free rate of return, alpha calculates a portfolio’s excess return in relation to its expected return. It shows how well the portfolio manager can produce returns that defy the benchmark.
When the alpha is positive, it indicates that the portfolio has outperformed the benchmark; when it is negative, it indicates underperformance. In contrast, the Sharpe ratio calculates a portfolio’s risk-adjusted return. It considers both the portfolio’s excess return and the returns’ volatility. Indicating that the portfolio has produced higher returns in relation to the degree of risk, a higher Sharpe ratio denotes a higher risk-adjusted return. When evaluating the portfolio returns’ deviation from the benchmark returns, tracking error offers a more accurate measurement than these metrics.
It provides information about the risk attached to the portfolio by concentrating on the excess returns’ volatility. Although alpha & Sharpe ratio offer a more thorough evaluation of the portfolio’s performance, tracking error is a helpful metric for assessing the degree of risk involved in the portfolio and the efficacy of the portfolio manager’s investment strategy. There are sophisticated methods for calculating tracking error in addition to the fundamental formula and calculation procedures.
Factor models & regression analysis are two of these methods. Factor models are statistical models that describe how a portfolio’s returns are affected by a number of variables, including market volatility, inflation, and interest rates. Portfolio managers can compute tracking error more precisely by estimating a portfolio’s expected returns and risk using factor models. The calculation of tracking error can also be accomplished through regression analysis. It entails accounting for additional variables that might affect returns by regressing the portfolio’s excess returns on the benchmark’s excess returns. Finding the sources of tracking error can be facilitated by using regression analysis to examine the relationship in greater detail between the portfolio and the benchmark.
With the help of these sophisticated methods, tracking error can be calculated more precisely & intelligently, giving fund managers and investors a better grasp of a portfolio’s risk and performance. An important part of portfolio management is tracking error monitoring and management. Investors & fund managers can spot any departures from the benchmark and take the necessary steps to mitigate the risk by keeping a close eye on tracking error. Establishing a target range for tracking error is a recommended practice for tracking error monitoring. This range ought to be determined by the investor’s risk tolerance & investing goals.
Investors can evaluate if the portfolio is tracking the benchmark within a tolerable risk threshold by establishing a target range. Periodically reviewing the investments & holdings in the portfolio is another recommended practice. Investors & fund managers can find any factors that might lead to tracking error & adjust as needed by looking at the composition of the portfolio and the investment choices made. When monitoring tracking error, the time horizon must also be taken into account. It’s possible that the tracking error’s short-term variations don’t accurately reflect the portfolio’s long-term performance.
It is critical to evaluate tracking error over a significant amount of time and with a long-term perspective. Ultimately, tracking error is a crucial performance indicator for contemporary portfolio management. It offers insightful information about a portfolio’s performance & risk, enabling fund managers & investors to assess the portfolio’s level of risk as well as the efficacy of their investment strategy. Investors & fund managers can make well-informed decisions regarding their portfolios by comprehending the components of tracking error, computing tracking error with the proper techniques, & interpreting tracking error results.
Although there are drawbacks to tracking error, it is a helpful tool for risk management and portfolio performance assessment. In the intricate and ever-changing world of investments, tracking error is essential for assisting fund managers and investors in navigating the opportunities and challenges present in the market. A deeper understanding of one’s portfolio and better decision-making are possible for investors who integrate tracking error into their investment process.
