Summary This strategy switches between a high yield corporate bond fund and a high yield municipal bond fund based on 3-month returns. A 3-month simple moving average filter is also used. The strategy is very low risk (i.e. low standard deviation and low maximum drawdown) while maintaining reasonable growth (~10% CAGR). Backtesting from 1986 using FAGIX and MMHYX produces CAGR = 11.3%, standard deviation = 5.5%, and maximum drawdown (based on monthly returns) = -5.5%. There are essentially no losing years. No load/no fee mutual funds must be selected for practical application. They are platform-dependent; for Schwab, I selected JAHYX and NHMAX as the best available no load/no fee mutual funds. Using JAHYX and NMHAX and backtesting to 2000, the strategy produces CAGR = 9.7%, standard deviation = 4.8%, and maximum drawdown = -3.5%. There are no losing years. This article explains a rather simple strategy that tactically switches between a high-yield corporate bond mutual fund and a high-yield municipal bond mutual fund, with money market being a safety net. The goal was to develop a low risk, capital-preservation strategy with reasonable growth (CAGR ~ 10%). I also desired to use mutual funds rather than ETFs to reduce volatility. This necessitated that the strategy be updated on a quarterly basis rather than a monthly basis (my usual preference). The reason these two bond asset classes were chosen was because they are not well-correlated; typically, their correlation is about 0.15. To show the feasibility of the strategy, I used two representative mutual funds that could be backtested to 1986 in Portfolio Visualizer (PV): Fidelity Capital and Income Fund (MUTF: FAGIX ) and MFS Municipal High Yield Bond Fund (MUTF: MMHYX ). Some might object to the usage of FAGIX as the high-yield corporate bond mutual fund because a small percentage of the fund is invested in equities rather than bonds. Fidelity Advisor High Income Advantage Class A (MUTF: FAHDX ) is actually a better representative of this class, but its history starts in 1987 in PV. I wanted to include 1987 in the analysis, so I used FAGIX instead of FAHDX. But I will show results using both FAGIX and FAHDX later in this article. The strategy uses 3-month relative strength momentum ranking to determine which asset to pick each quarter. In addition, the top-ranked asset must pass a 3-month simple moving average, MA, filter in order to be selected. If the asset does not pass this filter, then the money goes to the money market. This is a pretty simple set of parameters, and others have shown that a 3-month lookback period for bonds is most satisfactory. The backtesting was performed using the free Portfolio Visualizer (PV) software. Any investor can run these calculations and trade this strategy. The backtest results are shown below for FAGIX and MMHYX. CASHX (PV’s ticker for money market) is the cash filter asset. The timeframe is 1986 – present. It can be seen that the CAGR = 11.3%, the standard deviation, SD = 5.5%, the maximum drawdown based on monthly returns (MaxDD) = -5.5%, and the worst year = -0.3%. Risk adjustment return-on-investment can be seen using CAGR/SD and/or CAGR/MaxDD. In this strategy, CAGR/SD = 2.04, and CAGR/MaxDD = 2.02.

This is commonly referred to as a buy & hold strategy. The equal-weight strategy has a CAGR of 7.7%, but it has a MaxDD of -27.6% and a worst year return of -25.9%. The benefit of the tactical strategy I am proposing can readily be seen: almost 50% higher growth compared to the passive buy & hold strategy (CAGR of 11.3% versus 7.7%) and much less drawdown (-5.5% versus -27.6%). If FAHDX is substituted for FAGIX, the backtest timeframe becomes 1988 – present. The results are shown below. It can be seen that CAGR = 10.5%, SD = 5.6%, MaxDD = 6.5%, and worst year = +0.2%. The CAGR/SD = 1.89, and CAGR/MaxDD = 1.62.

I needed to find mutual funds with no loads and no redemption fees, and operating expenses (including 12b-1 fees) that are kept to a minimum. Of course, every platform has different funds that meet these requirements. I use the Schwab platform, and they provide a lot of no load/no fee options. After extensive searching, I selected Janus High-Yield T Shs Fund (MUTF: JAHYX ) as the best high yield corporate bond mutual fund, and Nuveen High Yield Municipal Bond Fund Class A (MUTF: NHMAX ) as the best high yield municipal bond mutual fund. These funds only permit backtesting to 2000. So the results shown below have a timeframe from 2000 – present. It can be seen that CAGR = 9.7%, SD = 4.8%, MaxDD = -3.4%, and the worst year = +1.6%. The CAGR/SD = 2.03, and the CAGR/MaxDD = 2.66 (a very good number).

The MA has been varied between 2 months and 4 months, and the lookback timing period (TP) was changed between 3 months and 4 months. The overall results do not change appreciably. Robustness of Strategy (click to enlarge) In summary, this article presents a very conservative tactical strategy that produces reasonable growth with very low risk. It is a quarterly updating strategy that uses less volatile mutual funds rather than ETFs. The basic strategy can be implemented on any platform, but care must be exercised in finding the best no load/no fee mutual funds for any given platform. For the Schwab platform, I believe the best mutual funds for this strategy are JAHYX and NHMAX. The pick for last quarter (July – September, 2015) was CASHX. The selection for this quarter (October – December, 2015) is NHMAX. Scalper1 News
