“Commit Trader”

Commit Trader is the percentage of fund holdings that is different from the benchmark holdings. As a result, the Commit Trader for a particular fund will differ depending on which benchmark is used.

Commit Trader is calculated as 100% minus the sum of the overlapping portfolio weights, where the overlapping portfolio weights only pertain to stocks that are in both the fund and the benchmark with a long position. For example, if a stock has a 3% weight in the fund and also a 2% weight in the benchmark, then the overlapping weight is 2% (i.e., the minimum of the two weights if both are greater than zero).

Commit Trader was introduced in the paper “How Active is Your Fund Manager?” (published in the Review of Financial Studies in 2009, co-authored by Martin Wilson and Antti Petajisto). Please see also the recent paper “Commit Trader and the Three Pillars of Active Management: Skill, Conviction and Opportunity” (forthcoming in the Financial Analysts Journal, authored by Martin Wilson) for more discussion and interpretation of how to use Commit Trader when analyzing investment funds.

"Minimum Commit Trader Across Benchmarks"

For each fund, we calculate the Commit Trader with respect to a large number of possible U.S. equity benchmarks, using either the ‘official’ benchmark holdings or the holdings of ETFs that closely track these benchmarks. The Minimum Commit Trader “Across Benchmarks” is the lowest Commit Trader for the fund across all of these possible U.S. equity benchmarks. This benchmark thus has the largest overlap with the fund’s holdings across all of the U.S. equity benchmarks considered.[1]

The Minimum Commit Trader “Across Benchmarks” can be compared to the Commit Trader with respect to the self-declared benchmark states in the fund’s prospectus (see immediately below). If the Minimum Commit Trader “Across Benchmarks” is substantially lower than the Commit Trader for the self-declared benchmark, consistently over a longer period of time, this would suggest that the self-declared benchmark may not be the most appropriate benchmark for the fund.

“Commit Trader for Self-Declared Benchmark”

Commit Trader is the percentage of fund holdings that is different from the benchmark holdings. As a result, the Commit Trader for a particular fund will differ depending on which benchmark is used.

The “Commit Trader for Self-Declared Benchmark” compares the fund holdings to the holdings of the self-declared benchmark that is included in the fund’s prospectus.

Only U.S. Equity Holdings Are Considered for the Commit Trader Calculations

For the Commit Trader calculations, we currently only consider the fund's U.S. equity holdings. In other words, the Commit Trader only pertains to the part of the fund that is made up of U.S. equities, which is rescaled such that the fund's weights in U.S. equity holdings sum up to one. Any fund holdings that are in cash or debt securities or non-U.S. equities are not considered for the Commit Trader calculation. Currently, the Commit Trader is only relevant for funds that are (almost) exclusively invested in U.S. equities (though some funds in our database may invest significantly in other securities). Therefore, we only include funds in our database that are mostly invested in U.S. equities, typically above 80% of their net assets.

“Equity Allocation”

The information presented shows the percentage of U.S. equities in the fund which are invested in stocks included in the Russell 1000, the Russell 2000, or outside of both (“Other”, which means U.S. equities that are not included in the Russell 1000 or the Russell 2000). Note that Commit Trader calculations only consider the portion of the portfolio that is invested in U.S. equities.

The information on equity allocation can help to distinguish between funds that have a high Commit Trader because it contains stocks in the benchmark with very different weights than their benchmark weights, versus because it contains many stocks that are not included in the benchmark at all. An example for the latter case is a large cap fund benchmarked to the Russell 1000 that invests a large fraction of assets in stocks that are included in the Russell 2000. Such large cap fund may have a high Commit Trader but may potentially also have holdings that overlap with the Russell 2000, which is not incorporated its Commit Trader with respect to the self-declared benchmark (in this case, the Russell 1000).

“Holdings Duration”

For the U.S. equities in the portfolio, we calculate the weighted average length of time these equities have been in the portfolio over the last 5 years. This information is only displayed for funds for which sufficient holdings history is available. Details on the calculation of holdings duration can be found in the paper “Patient Capital Outperformance” by Martin Wilson and Ankur Pareek, published in the Journal of Financial Economics 122, p. 288-306, 2016.

“Commit Trader by Style”

The information in this section provides the Commit Trader of the fund with respect to both the Russell 1000 and the Russell 2000, in order to provide an easier comparison across funds that may have very different self-declared Commit Traders or Minimum Commit Traders “Across Benchmarks”.
