Tactical Adaptive Global Strategy Whitepaper

Updated August 10, 2023

TAAS offers two Tactical Adaptive Strategies to investors:

  • Tactical Adaptive Global provides broad exposure to domestic and international equities, fixed income, real estate, commodities and precious metals.
  • Tactical Adaptive Income invests across a diversified basket of fixed income subclasses designed to provide a high level of income coupled with exceptionally low risk.

This paper describes the design and principles which underlie the Tactical Adaptive Global Strategy in considerable detail. It is written for subscribers and prospective subscribers who seek to more fully understand the strategy.

Broad Markets Exposure

The Tactical Adaptive Global Strategy is our flagship strategy. It provides hard-to-beat returns and exceptionally low investment risk across a blended portfolio of global equities, fixed income, real estate, commodities, and precious metals.

Measured across four market cycles between January 2000 and March 2023, Adaptive Global shows the following approximate percentages invested across major asset classes:

  • Equities 40%
  • Fixed income 34%
  • Real Estate 14%
  • Precious metals & commodities 6%
  • Cash 6%

Historical, backtested performance for both cycles shows a Compound Annual Growth Rate (CAGR) of 14%+ and a Maximum Monthly Drawdown (MaxMD) of less than 8%.

Before moving on, let's set the stage with brief explanations of both Market Cycles and Tactical Asset Allocation.

Market Cycles

Our backtest results tables are constructed across market cycles beginning in January 2000.

The second market cycle covers October 2007 through December 2019. The Adaptive Global and Adaptive Income strategies were developed using the first 10+- years of data from this cycle while the final 5+- years are actual.

The first market cycle covers January 2000 through September 2007. This market cycle was used to provide out of sample validation of strategy results from the second market cycle. The fact that the return and risk metrics for the first cycle are statistically comparable to those for the second cycle validates the process.

The fund baskets for our tactical strategies are constructed from indexed Exchange Traded Funds (ETFs) with just two exceptions, an Open End Fund and a Closed End Fund, both with long history. A number of the ETFs we use were not created until 2007+. In each case, we infill using predecessor Open End Funds (OEFs) for which the indexing and/or subclass is substantially similar to the ETF.

We have been asked if it is possible to extend backtests to the 1970’s. While a few publishers attempt this; we believe it is not possible to produce credible results for all but the most basic TAA strategies due to the lack of funds with substantially similar indexing and/or classification. Doing so would force me to stretch the term "substantial" far beyond my comfort level.

Tactical Asset Allocation

Tactical Asset Allocation (TAA) is among the best investment tools available for navigating Full Market Cycles. While TAA tends to lag in late bull markets, it offers opportunities for higher Compound Annual Growth Rates and lower Maximum Drawdowns across a full bull/bear market cycle. Among the greatest strengths of TAA is its mechanical, rules-based approach, which not only keeps the portfolio attuned with market conditions but reduces the anxiety of managing the portfolio.

Perhaps the single biggest distinction between Tactical Asset Allocation and Modern Portfolio Theory is that while Modern Portfolio Theory seeks to reduce risk by spreading it across several asset classes, Tactical Asset Allocation seeks to reduce risk by cutting it. - Earl Adamy

Building A Global Fund Basket

The foundation of Adaptive Global is a basket of low-cost, passively managed, index Exchange Traded Funds (ETFs). It is our Market Conditions Model and Tactical Model which turn this basket into a dynamic, actively managed investment strategy.

Tactical Asset Allocation strategies generally use a basket of 5 to 10 funds; however we use a much larger basket for improved global and asset class coverage. I maintain a funds database of nearly 400 funds, most of which have gone through a “tryout” process for inclusion in the basket. 23 funds have made the cut:

  • 7 domestic equity index funds including large, medium and small caps
  • 4 international equity index funds covering Europe, Asia, and Emerging Markets
  • 1 domestic real estate fund
  • 1 international real estate fund
  • 6 US Treasury funds from short to long duration
  • 1 domestic investment grade bond fund
  • 2 commodity and resource funds
  • 1 precious metals fund

Notable for their absence are international bond funds, none of which carried its weight when added to the fund basket and few of which have the required history.

Market Conditions

A large basket also allows us to tailor fund selections to market conditions. For example, we don’t want to be invested in short term Treasuries in a rip roaring bull market nor do we want to be invested in emerging market equities during a bear market.

The Market Conditions Model (see What Is A Market Conditions Model? How Does It Lower Risk?) is a multi-factor model that tracks price momentum, credit risk, market valuation and analyzes the interrelationships of these factors to identify periods of high and low directional probability. The Model identifies three market conditions:

  • Favorable: A strongly trending market with little risk of major decline. Unexpected declines are likely to be temporary and relatively short-lived.
  • Balanced: Risks of market decline and opportunity for advance are roughly equal; however conditions are supportive of increased volatility and uncertainty.
  • Hostile: High risk of extended market Correction (10%+) and Bear Market (20%+) declines and large equity drawdowns.

The Model measures market conditions in a probabilistic way. For example, it may signal Favorable conditions if there is a high probability of a market rise with low risk. However, a signal of Favorable conditions is not a guarantee of a Bull Market nor does a signal of Hostile conditions presage, with certainty, a Bear Market. However, the three conditions, when coupled with the appropriate fund baskets, work incredibly well in lowering risk and improving returns across full market cycles.

The Adaptive Global fund basket is further tailored to current market conditions:

  • Favorable: The fund basket emphasizes domestic and international equities supplemented with real estate, commodities and fixed income.
  • Balanced: The fund basket includes a mix of larger domestic and international equity funds together with a complement of high quality fixed income.
  • Hostile: The fund basket emphasizes a broad spectrum of government fixed income together with a limited selection of large cap equity funds and commodities.

Identifying The Trend

Five years of research and development went into Adaptive Dynamic Momentum (see Adaptive Dynamic Momentum: Improving Trend Identification), our ranking algorithm. While most tactical ranking is performed using fixed length periods; Adaptive Dynamic Momentum identifies the optimum ranking criteria for each fund, each week. It does this by identifying primary and secondary trends as well as applying additional filtering to minimize noise.

Adaptive Dynamic Momentum is used by our Tactical Model to provide the critical pathway to finding (and sticking with) winners while avoiding (and/or quickly discarding) losers.

Fund ranking is just the beginning of the process for selecting funds for the next rebalance. We are just as interested in how well a fund is likely to continue performing in the future as how well it has performed in the past. Adaptive Dynamic Momentum assigns a confidence level to each fund's trend ranking. We use the combined ranking and confidence level to make the final selections.

Allocating Funds

Once the funds eligible for the next rebalance are selected, portfolio weights are assigned to each fund. We employ volatility weighting algorithms which allocate larger percentages to funds with low volatility and smaller percentages to funds with high volatility. The small decrease in return is offset with a larger decrease in portfolio volatility.

Adaptive Global spreads the allocation across the best 3-5 funds for diversification. The number of funds used depends upon the market condition with Favorable conditions warranting a more focused allocation while Balanced and Hostile conditions employ greater diversification.

One of the newest features in our Tactical Model reduces the number of trades. Before replacing an existing position with a higher trend scoring fund, the Model checks to see if it can hold the existing position without compromising expected performance. For the Adaptive Income Strategy, this reduces trades by 6% while extending the average holding period for some funds by as much as 18% providing more opportunity for favorable tax treatment.

Scoring The Results

The Tactical Model is run through four market cycles from 2000 - 2023 to calculate Compound Annual Growth Rate (CAGR), Maximum Monthly and Daily Drawdown, and a number of other statistics including monthly and annual returns.

Tactical Global scores impressive returns for the entire 23+ years and for each of the Market Conditions. And the low drawdowns are exceptional. These are the kind of results which can both enhance your lifestyle and allow you to sleep soundly at night. A few points are worth highlighting here:

  • Note the six month maximum drawdown recovery of Adaptive Global compared to nearly 5 years for the S&P 500.
  • The Ulcer Index, which ignores gains, measures the depth and duration of drawdowns. The Ulcer Index for the S&P 500 is eight times higher!
  • The % Gains Captured and % Loss Captured consistently outperforms the S&P 500 in capturing a large percentage of the gains while capturing a much smaller percentage of the losses.

The statistical summary (at time of writing) suggests a Sustainable Withdrawal Rate of 6.6%. How is this calculated? (See Sustainable Withdrawal Rate)

  1. Assume that the Maximum Monthly Drawdown (7.7%) occurs on the day that a $100,000 investment in the strategy takes place. (Disaster scenario) That leaves $92,300 to invest.
  2. Multiply $92,300 by the CAGR of 14.3% leaving $13,199
  3. Withdraw 1/2 of the $13,199 which equals $6,600 while leaving the remaining half invested to cover inflation and a safety factor

The calculated Sustainable Withdrawal Rate is well above the yields on all of our funds. How is this possible? It is due to large capital gains, especially during the early stages of the bull market. While capital gains are great, we want to identify a rate which does not rely upon out-sized capital gains. Running the Tactical Model with different withdrawal rates provides some additional insight:

  • 4% withdrawal rate: Start with $100,000 and withdraw 4.0% annually in equal monthly installments. The $100,000 would have grown steadily to $910,588 in August 2021 before declining to $873,061 in March 2023.
  • 5% withdrawal rate: Start with $100,000 and withdraw 5.0% annually in equal monthly installments. The $100,000 would have grown steadily to $732,655 in August 2021 before declining to $691,556 in March 2023.
  • 6% withdrawal rate: Start with $100,000 and withdraw 6.0% annually in equal monthly installments. The $100,000 would have grown steadily to $589,195 in August 2021 before declining to $547,412 in March 2023.
  • 7% withdrawal rate: Start with $100,000 and withdraw 6.0% annually in equal monthly installments. The $100,000 would have grown steadily to $473,831 in August 2021 before declining to $433,319 in March 2023.

We can also use the Tactical Model to calculate the Sustainable Withdrawal Rate using just the past 10, 5 and 3 years:

  • 10 years 5.1%
  • 5 years: 4.3%
  • 3 years: 5.9%

This suggests that a withdrawal rate of 5%-6% could prove more sustainable than 6.6%. Why? Because the big gains from the early bull market are behind us and we have no way of knowing when the next bull market will begin. Further, one should not lose sight of the fact that returns during the next 10 years are unlikely to match those of the past 10.

When it comes to withdrawals, I strongly prefer roughly equal monthly withdrawals to level the portfolio volatility risk. Those with RMDs can always adjust or supplement the final withdrawal to meet requirements.


The Adaptive Global Strategy smoothly and effectively transitions between risk on and risk off while delivering exceptional returns.

It combines the use of low-cost, passive index funds with an active management strategy to reduce losses and improve returns. There is a large body of academic research which is both substantive and compelling in making the case for the use of Tactical Asset Allocation to manage all or part of an investment portfolio. With historically extreme equity valuations and increased volatility in credit markets, investors should consider using Adaptive Global for part of their portfolios to improve returns and reduce risks.
