Enhancing actively managed strategies

Exploring rules-based enhancements for improving returns when invested in risk assets.
The goal of active investment management is compelling. Capturing more of an asset class’s upside than its downside is an investment recipe for success. In a simple implementation, this could be accomplished by actively switching between a risk asset such as large-cap U.S. equities and a risk-free asset such as cash. Effectively executed, this strategy has the potential to deliver an attractive balance between return and risk. However, what if there was a way to improve returns when invested in a risk asset? It seems that this could add additional value to an actively managed portfolio.

Enhancing an active strategy to deliver the potential for increased return while maintaining a desired risk framework requires a second level of decision-making. In addition to deciding to be exposed to a risk asset such as large-cap U.S. equities, the active manager, interested in potentially increasing returns, should also be deciding what the optimal large-cap U.S. equity exposure is at the time of the allocation. For the purposes of this article, we will call this two-decision approach an Enhanced Active Strategy (EAS).

To embrace an EAS, the active manager has to recognize two things:

  1. Modified exposures to an asset class perform differently through time.
  2. A manager can create a rules-based approach to selecting a preferred exposure.

To illustrate these two points, it is helpful to consider some examples. Let’s assume a manager runs an active strategy that switches between the S&P 500 and cash, and the manager is open to the concept of adapting this strategy to an EAS.

First, the manager would need to identify alternative S&P 500 exposures that perform differently through time. Let’s start with the S&P 500 cap-weighted and equal-weighted indexes. It makes sense that these two indexes would perform differently over time because of their security weightings. When the largest companies in the index are outperforming other constituents, the cap-weighted index will outperform. When performance is more dispersed across constituents, the equal-weighted index should outperform. The following chart divides the price of the S&P 500 Equal Weight Index (S&P EWI) by the price of the S&P 500 and plots the result over time. When the resulting line is moving upward, the equal-weight index is outperforming the cap-weighted S&P 500, and when the line is moving downward, the S&P 500 is outperforming its equal-weighted counterpart. It is clear from the graph that there are extended periods of outperformance of one index over the other.


Next, the manager needs to determine if these performance differences are exploitable. To test this, we overlaid a 200-day moving average (MVAG) and applied a simple trading rule. When the S&P EWI/S&P line crosses above the 200-day MVAG line, we invest in the equal-weight index, and when the S&P EWI/S&P line crosses below, we invest in the cap-weighted index. This simple trading rule added value. From March 2007 through December 2016, following this trading rule resulted in a return of 163.2%, versus a return of 150.5% and 117.5% for the S&P EWI and S&P 500, respectively.

In this example, the EAS would first determine if exposure to the S&P 500 or cash is preferred. Then, if exposure to the S&P 500 is preferred, determine if equal-weight or cap-weight exposure is preferred.

It may be possible for active managers to further enhance their active strategies.

Recognizing that the weighting differences between the S&P EWI and S&P 500 cap-weighted index drive the performance differences, it is fair to explore if weighting can be further differentiated. To explore this, we divided the price of the S&P Equal Weight Index by the price of the Russell Top 50 Index, which represents a market-cap-weighted index of the 50 largest stocks in the Russell 3000 universe of U.S.-based equities. Following the same simple trading rule we used with the S&P EWI/S&P 500 “index,” the S&P 500 EWI/Russell Top 50 “index” delivered 176%—versus the 150.5%, 108.6%, and 117.5% returns for the S&P 500 EWI, Russell Top 50, and S&P 500 Indexes, respectively.


While the analysis presented here is simplistic, it illustrates that it may be possible for active managers to further enhance their active strategies through a process similar to the one discussed, adopting a two-stage, rules-based decision-making process. And, given the explosion of investable exposures, it may be the right time to consider this type of approach for enhancing actively managed strategies.
Disclosure: Investing involves risk, including the possible loss of principal. Index definitions: The Standard and Poor’s 500 Index is a broad-based index, the performance of which is based on the performance of 500 widely held common stocks chosen for market size, liquidity, and industry group representation. The referenced indices are unmanaged and not available for direct investment. Index performance does not reflect transaction costs, fees, or expenses. The S&P EWI has the same constituents as the capitalization-weighted S&P 500 Index, but each company in the S&P EWI is allocated a fixed weight, rebalancing quarterly. The Russell Top 50 Index is a market-capitalization-weighted index of the 50 largest stocks in the Russell 3000 universe of U.S.-based equities.
