Asset Rotation Model

The Asset Rotation Model (ARM) helps you determine how to position your investments to capitalize on growth in both stocks and bonds, while largely avoiding those unfortunate periods of major market declines.

The ARM uses a dynamic approach to asset allocation. It examines the performance of both stocks and bonds, and positions itself accordingly to generate maximum growth for a portfolio. Under adverse economic conditions, when stocks are losing value, the ARM will shift to bonds to avoid the major losses associated with market crashes.

The chart below shows the backtested performance of the ARM over the last 23 years. For comparison, the performance of SPY (an index fund that tracks the performance of the S&P 500), AGG (an index fund that tracks the Barclays U.S. Aggregate Bond Index), and a 60/40 blend of those two funds are included in the chart. By using a dynamic approach to asset allocation, the ARM was able to generate significantly higher returns than both stocks and bonds, while avoiding major losses during the last three market crashes.

Model performance represents total returns and includes reinvestment of dividends and interest. No management fees or transaction costs are included. Historical performance is not an indication or guarantee of future performance.


The Asset Rotation Model selects the top performing asset class each month (between stocks and bonds) and shifts its investment accordingly. Often, the model remains in a particular asset class for months or years at a time.

The strategy behind the Asset Rotation Model allows it to avoid severe market declines. In the early 2000’s the ARM was able to sidestep the dot-com collapse by moving to the safety of bonds. When stocks began to recover, the ARM shifted back into stocks and rode the bull market higher until the beginning of the financial crisis. At that point, the deteriorating returns in stocks caused the model to shift back into bonds, safely riding out the financial crisis with minimal losses. When stocks resumed their ascent once again, the ARM switched back into stocks to take advantage of their strong growth.

This unique approach to asset allocation contradicts much of the standard industry dogma when it comes to choosing between stocks and bonds. However, many investors immediately recognize the benefit of only being exposed to a certain asset class when it exhibits positive price performance. Why sit with stocks through a market crash? And why hold bonds if their total returns are negative for extended periods of time?

The ARM not only delivers higher returns, it also substantially reduces overall portfolio risk. The table below contains a series of performance metrics that allow you to compare the ARM against portfolios of both stocks and bonds.

Key Performance Highlights:

  • Over the last 23 years the ARM’s compound annual return has significantly outpaced that of both stocks and bonds, as well as a blended portfolio.
  • When compared to stocks, the ARM generates strong excess returns (alpha) while experiencing much less volatility (risk).
  • The reduced volatility and enhanced returns provide for notably higher risk-adjusted returns, as evidenced by the Sharpe, Sortino and Treynor ratios, and a positive alpha.
  • Stocks lost over half their value during the financial crisis. The ARM was able to sidestep those losses by repositioning the portfolio into bonds.

The ARM utilizes two exchange-traded funds (ETFs), which are listed below. SPY is the largest and most widely used ETF for exposure to the S&P 500. AGG is the largest and most widely used bond ETF; it tracks the Barclays U.S. Aggregate Bond Index.
