Managed futures – how to diversify with trend following
Investors are scouring the investment universe for sources of return which are not correlated to traditional equity and fixed income performance. Trend following may offer an attractive return profile for such investors.
By design, the systematic nature of trend following strategies - which invest on a long/ short basis across asset classes entirely on the basis of trend signals (not forecasts) – makes them an interesting complement to traditional, discretionary stock and bond portfolios. Traditional portfolios may be sensitive to macro factors such as growth expectations and changes in interest rates and investors seem to worry now more than ever, about how diversified their underlying holdings actually are.
We seek to address several fundamental implementation questions regarding allocating to trend following, including why now might be an appropriate time to invest and how to fund and size a trend following allocation.
The Need for Diversification in a Rising Rate Environment
After eight years of accommodative monetary policy, the Fed appears poised to continue raising interest rates which could create losses for holders of Fixed Income assets. Figure 1 shows the expected impact a rise in rates could have on the return of 10-year US Treasuries, demonstrating that even a modest upward shift in rates would be painful for bondholders. For example, if the current issue 10-year Treasury yield increases +50 basis points over the next year, investors would expect to incur a -2.68% loss on a total return basis.
Traditionally, the diversification implicit in a 60/40 portfolio framework might be expected to offset such a loss as equities tend to outperform bonds in rising rate environments. However, with equities trading close to historical valuation peaks on the back of an easy financing environment and accommodative monetary policy, many investors are reducing their return expectations for equities and ascribing the possibility of a higher than historical correlation between stocks and bonds in a rising rate environment. This presents a potentially daunting scenario for many investors.
Consequently, investors are scouring the investment universe for sources of return which are not correlated to traditional equity and fixed income performance. Trend following may offer an attractive return profile for such investors. Interest rate cycles are often lengthy as policy adjustments are effectuated over the course of months or years. As a result, these cycles may coincide with sustained trends, creating profit opportunities for trend followers. In this way, trend following has the potential to profit from a period of rising interest rates without depending upon positive equity market performance.
Trend Following: Tactical Holding or Core Diversifier?
Figure 2 shows the correlation of trend following to a range of assets commonly held in investor portfolios, many of which have a high correlation to one another, reflecting a propensity to suffer steep losses concurrently. Trend following has not only demonstrated a low (or negative) correlation to equities and bonds over time, it is also uncorrelated from most other asset classes. As such, the introduction of trend following into traditional portfolios has historically represented an effective means of improving overall portfolio risk-return characteristics.
In addition, there is a significant body of work to support the notion that the distribution of trend following returns is skewed to the positive, i.e., there are generally fewer scenarios where a disproportionately large amount of money is lost, and there tend to be several episodes where larger amounts are made (Figure 3)
Finally, trend following strategies have historically exhibited shallower drawdowns than equities. As illustrated in Figure 4, maximum drawdowns for trend following strategies tend to occur on the scale of 1.5x their annualized volatility (this compares to almost 3.5x for equities) and subsequent recovery times tend to be shorter than equities. In addition, trend following can significantly outperform during equity crisis periods, making the strategy particularly attractive to investors seeking to stabilize returns and reduce overall portfolio risk.
The uncorrelated return profile of trend following, combined with its potential to generate positive returns across a range of market environments with less downside risk than equities, leads most investors to view the strategy not as a tactical allocation which can be timed, but rather as a core portfolio diversifier which can play an important role in achieving long term investment goals.
Funding an Allocation to Trend Following
Trend following differs from most long/short strategies in that it seeks to time its exposures (long or short) to markets, and thus does not provide a persistent beta to any particular market. This presents a challenge to investors seeking to incorporate trend following into their portfolios using traditional portfolio optimization techniques. As such, investors may need to alter their portfolio construction methodology in integrating trend following into their portfolios.
One approach may be to base allocation decisions on specific market outlooks; for instance, investors concerned about overextended stock prices may look to trend following as a replacement for specific equity exposures, while investors concerned about rising rates may fund their trend exposures from existing duration risk. Alternately, investor allocations may be based on risk tolerance. While equities represent approximately 60% of exposure in a typical investor’s portfolio in capital allocation terms, they are responsible for approximately 90% of the risk in such portfolios, and this risk concentration may leave portfolios susceptible to large losses during equity drawdowns.
Figure 5 compares the performance of trend following versus equities and bonds since 2000. The analysis suggests that, similar to bonds, trend following has the ability to stabilize portfolios when equity markets decline while also generating positive performance when equity markets are rising. This suggests that investors seeking greater portfolio stability may prefer to fund their trend following exposure from equities.
The potential drawback to this is that trend following (like most other investments) may lag equities during periods of very strong equity performance and return expectations should be adjusted accordingly.
Conversely, trend following has historically provided positive returns during crisis periods, while simultaneously delivering better performance than investment grade bonds in non-crisis periods. While this may position the strategy as an attractive bond substitute, it should be noted that most trend following strategies exhibit a higher volatility than traditional fixed income holdings, and as such, investors need to be comfortable accepting the potential for more risk and larger drawdowns.
Typically trend following strategies are calibrated to a pre-determined target volatility level, and investor allocation decisions based on risk tolerance requires an understanding of the level and use of leverage within their strategy allocation. Because volatility targets impact both the potential for returns and the magnitude of drawdowns, investors should adjust their drawdown expectations accordingly.
Taking these trade-offs into consideration, investors with a higher risk tolerance might consider funding from bonds, while investors with a lower risk tolerance might choose to fund from equities.
Sizing an Allocation to Trend Following
Ultimately, determining how much to allocate to a trend following strategy is subject to a variety of factors such as individual investment objectives and risk constraints, as well as the weights and correlations of existing portfolio holdings.
- A left shift of the efficient frontier
- A similar return with approximately 1.7% lower risk (standard deviation) per annum
- A 0.44% higher per annum return for the same level of risk (10% annualized in this example)
Trend following strategies may serve as an important portfolio diversification tool. They have generally served to reduce portfolio drawdowns in historical crisis periods while producing similar (or higher) returns than investment grade bonds during extended equity market rallies. Further, these strategies may not be susceptible to some of the same issues facing bond portfolios in a rising interest rate environment; to the contrary, they may have the potential to reduce duration risk and profit from a prolonged rising rate cycle.
Allocating to the space does present some interesting challenges, and determining how much to invest and how to fund an investment will depend largely on individual portfolio objectives and risk tolerances. When considering a trend following strategy we encourage investors to examine the total mix of risks, including:
- Level of strategy diversification and correlations to equity and interest rate risk
- Drawdown potential across different market environments
- Level and use of leverage
- Cash management policies
- Fees, which can vary significantly depending on implementation
